Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The following describes the process shown in fig. 1 provided in the present application:
referring to fig. 1, fig. 1 is a flowchart of a bandwidth allocation method provided in the present application. The process is applied to a network device, and as shown in fig. 1, the process may include the following steps:
Wherein the shared bandwidth is initially pre-reserved; the FlexE group binds at least one FlexE service port.
The network device includes a plurality of physical ports, where the plurality of physical ports may use part of the physical ports to form at least one FlexE group, or may use all the physical ports to form at least one FlexE group, where, for example, one FlexE group may include at least one physical port, each physical port is configured with bandwidth resources correspondingly, and then the total bandwidth resources corresponding to the FlexE group refer to a sum of the bandwidth resources configured for each physical port.
For example, if the FlexE group includes two physical ports, which are respectively denoted as physical port a and physical port B, the bandwidth resource configured for physical port a is a1, and the bandwidth resource configured for physical port B is B1, then the total bandwidth resource corresponding to the FlexE group is the sum of a1 and B1.
The first partial bandwidth resource in this embodiment is only named for convenience of distinguishing from the following partial bandwidth resource, and is not used to limit a certain partial bandwidth resource.
For one embodiment, the shared bandwidth may be set according to an integer multiple of the basic bandwidth, for example, if the basic bandwidth is 5G, the shared bandwidth may be 30G or 50G.
In this embodiment, the FlexE group is bound to at least one FlexE service port, which may be understood as that the FlexE service port and a physical port in the bound FlexE group are in a mapping relationship, so that a service stream forwarded by each FlexE service port may be forwarded through the physical port in the bound FlexE group.
And 102, allocating corresponding bandwidth resources to each Flexe service port according to the set service influence factor of each Flexe service port.
The sum of the bandwidth resources allocated to each FlexE service port is the remaining bandwidth resources except the first part of bandwidth resources in the total bandwidth resources.
In this step, each FlexE service port is pre-assigned which service type to forward the service flow, that is, the FlexE service port is related to the service type to which the FlexE service port forwards the service flow, and the service impact factor may be used to indicate the importance degree of the FlexE service port forwarding the service flow, where a larger service impact factor of the FlexE service port indicates a higher importance degree of the FlexE service port forwarding the service flow, and conversely, a smaller service impact factor of the FlexE service port indicates a lower importance degree of the FlexE service port forwarding the service flow. Thus, more bandwidth resources are allocated to the FlexE service port with a large service impact factor, less bandwidth resources are allocated to the FlexE service port with a small service impact factor, and if the service impact factors of the FlexE service ports are not different from each other, equal bandwidth resources can be allocated to the FlexE service ports. As an embodiment, the sum of the service impact factors of the FlexE service ports is 1.
Illustratively, the service flow forwarded by the user requirement comprises a video service flow, a short message service flow and a voice service flow, and the video service flow, the voice service flow and the short message service flow are sequentially ordered from high to low according to the importance degree of the service flow, so that the service impact factor of the FlexE service port for forwarding the video service flow is highest, the service impact factor of the FlexE service port for forwarding the voice service flow is next to the service impact factor of the FlexE service port for forwarding the voice service flow, and the service impact factor of the FlexE service port for forwarding the short message service flow is lowest, based on which, the service impact factor of the FlexE service port for forwarding the video service flow is set to 0.5, the service impact factor of the FlexE service port for forwarding the voice service flow is set to 0.3, the service impact factor of the FlexE service port for forwarding the short message service flow is set to 0.2, if the total bandwidth is 100G, and the reserved shared bandwidth is 30G, then the allocated bandwidth resource for the FlexE service port for forwarding the video service flow is (100-30 x 0.5G), the bandwidth resources allocated to the FlexE service port for forwarding the voice service stream are (100-30) × 0.3G, and the bandwidth resources allocated to the FlexE service port for forwarding the short message service stream are (100-30) × 0.2G.
And 103, when the bandwidth utilization rate of at least one Flexe service port exceeds the set bandwidth threshold value, selecting the bandwidth resource allocated to each Flexe service port from the shared bandwidth and correspondingly allocating the bandwidth resource to each Flexe service port.
In this step, for a FlexE service port, the bandwidth utilization rate of the FlexE service port refers to a ratio of the currently used bandwidth resource of the FlexE service port to the bandwidth resource allocated to the FlexE service port in step 102.
As an embodiment, the bandwidth threshold may be determined according to the service type to which the service flow forwarded by each FlexE service port belongs, the bandwidth thresholds set corresponding to the FlexE service ports may be different, and the bandwidth thresholds set corresponding to the FlexE service ports may also all be set to the same value, for example, the preset percentage of the bandwidth resource allocated to one FlexE service port may be set to 100%, the preset percentage of the bandwidth resource allocated to another FlexE service port may be set to 95%, or the bandwidth thresholds set corresponding to the FlexE service ports may also all be set to 95%.
For example, if the bandwidth threshold corresponding to the FlexE service port for forwarding the video service stream can be set to 90%, it means that when it is monitored that the bandwidth utilization rate of the FlexE service port exceeds 90%, it is necessary to select the bandwidth resource allocated to the FlexE service port from the shared bandwidth, and correspondingly allocate the allocated bandwidth resource to the FlexE service port; if the bandwidth threshold corresponding to the FlexE service port for forwarding the voice service stream can be set to 95%, it means that when the bandwidth utilization rate of the FlexE service port exceeds 95% by monitoring, the bandwidth resource allocated to the FlexE service port needs to be selected from the shared bandwidth, and the allocated bandwidth resource is correspondingly allocated to the FlexE service port; if the bandwidth threshold corresponding to the FlexE service port for forwarding the short message service stream can be set to 100%, it means that when the bandwidth utilization rate of the FlexE service port exceeds 100%, the bandwidth resource allocated to the FlexE service port needs to be selected from the shared bandwidth, and the allocated bandwidth resource is correspondingly allocated to the FlexE service port.
In this embodiment, when it is monitored that the bandwidth utilization rate of at least one FlexE service port exceeds the set bandwidth threshold, this indicates that traffic congestion occurs in each monitored FlexE service port, and to avoid further causing data packet loss, a bandwidth resource allocated to each FlexE service port is selected from the shared bandwidth and correspondingly allocated to each FlexE service port, so that the bandwidth resource allocated to each FlexE service port is extended, each FlexE service port can further forward a suddenly increased traffic, and the problem of reducing data packet loss due to FlexE service port congestion caused by the suddenly increased traffic is avoided.
In this step, monitoring that the bandwidth usage rate of at least one FlexE service port exceeds the set bandwidth threshold may include two cases, one case is monitoring that the bandwidth usage rate of only one FlexE service port exceeds the set bandwidth threshold, and the other case is monitoring that the bandwidth usage rate of at least two FlexE service ports exceeds the set bandwidth threshold, for the two cases, in some embodiments, as shown in fig. 2, one implementation manner of implementing step 103 may include step 1031:
And the second part of bandwidth resources are less than or equal to the bandwidth resources allocated to the Flexe service port.
In this embodiment, the second part of bandwidth resources are only named for convenience of description, and are not used to limit a certain bandwidth resource.
In this embodiment, the second part of bandwidth resources is less than or equal to the shared bandwidth resources, and the second part of bandwidth resources of the basic bandwidth multiple may be allocated to the FlexE service port on the basis of the basic bandwidth, so that after the second part of bandwidth resources are allocated to the FlexE service port, the FlexE service port can forward the current service traffic as much as possible, thereby avoiding the problem of packet loss caused by congestion of the FlexE service port, and at the same time, the bandwidth usage rate of the total bandwidth corresponding to the FlexE Group can be further improved, so as to improve the rationality of bandwidth allocation.
As another example, as shown in fig. 2, another implementation of implementing step 103 may include step 1032:
In this embodiment, when it is monitored that the bandwidth utilization rates of two or more FlexE service ports exceed the set bandwidth threshold, this means that a congestion problem may occur at the same time for a plurality of FlexE service ports, and in view of limited shared bandwidth, in this embodiment, bandwidth resource allocation is preferentially performed for the FlexE service port with the largest service impact factor from among the shared bandwidths according to the service impact factors of each FlexE service port, and in order to facilitate other types of service flows to avoid congestion as much as possible, the third part of bandwidth resources is less than or equal to the bandwidth resources allocated by the current FlexE service port, so that the other FlexE service ports whose bandwidth utilization rates exceed the set bandwidth threshold can also forward service flows through the allocated third part of bandwidth resources. For convenience of description, the FlexE service port to which the third part of bandwidth resources are already allocated is denoted as a FlexE service port a, then after the third part of bandwidth resources are allocated to the current FlexE service port, when it is determined whether bandwidth resources still exist in the shared bandwidth, if bandwidth resources still exist, the step of selecting the current FlexE service port from all the monitored FlexE service ports as the FlexE service port with the largest service impact factor is returned. It should be noted that, all the FlexE service ports in the return execution step refer to the FlexE service ports of all the monitored FlexE service ports except the FlexE service port a to which the third part of bandwidth resources are allocated, the third part of bandwidth resources are selected from the shared bandwidth, and the third part of bandwidth resources are allocated to the current FlexE service port, which is the FlexE service port a, until the shared bandwidth is completely allocated, or all the monitored FlexE service ports are completely allocated with the third part of bandwidth resources.
It can be seen that, in the technical solution provided in this embodiment, when it is monitored that the bandwidth usage rates of the two FlexE service ports exceed the set bandwidth threshold, the network device allocates a third part of bandwidth resources to the monitored FlexE service ports according to the service impact factors of the FlexE service ports until all the monitored FlexE service ports are allocated or all the bandwidth resources sharing the bandwidth are allocated. Therefore, a Flexe service port capable of transmitting a service flow with a large service influence factor is not limited by a set bandwidth threshold any more, even when the bandwidth utilization rate of the Flexe service port exceeds the set bandwidth threshold, the reserved shared bandwidth is dynamically called to relieve the packet loss problem caused by traffic congestion, meanwhile, the bandwidth utilization rate of the Flexe Group corresponding to the total bandwidth can be improved, and further the reasonability of bandwidth allocation can be improved.
So far, the description shown in fig. 1 is completed.
Therefore, in the technical scheme of the embodiment of the application, the network device monitors the FlexE service ports bound with the FlexE, and when it is monitored that the bandwidth utilization rate of at least one FlexE service port exceeds the set bandwidth threshold, the bandwidth resources allocated to each FlexE service port are selected from the pre-reserved shared bandwidth and correspondingly allocated to each FlexE service port, so that each FlexE service port is no longer limited by the configured bandwidth resources, and when the bandwidth utilization rate of the FlexE service port exceeds the set bandwidth threshold, the reserved shared bandwidth is dynamically called to alleviate the problem of packet loss caused by congestion of service traffic, and meanwhile, the bandwidth utilization rate of the FlexE Group corresponding to the total bandwidth can be improved, and further, the rationality of bandwidth allocation can be improved.
After completing the description shown in fig. 2, after the monitored FlexE service ports have allocated bandwidth resources from the shared bandwidth, monitoring whether the FlexE service ports have bandwidth usage rates of the FlexE service ports smaller than the bandwidth threshold, and reclaiming the bandwidth resources allocated to the FlexE service ports having bandwidth usage rates lower than the bandwidth threshold, as an embodiment, as shown in fig. 3, after step 1031, the method further includes the following step 1033:
and 1033, when it is monitored that the bandwidth utilization rate of the FlexE service port to which the second part of bandwidth resources are allocated is smaller than the set bandwidth threshold, recovering the allocated second part of bandwidth resources in the FlexE service port, and adding the recovered second part of bandwidth resources to the shared bandwidth.
It should be noted that the bandwidth utilization rate in this step is the same as the determination method of the bandwidth utilization rate described above, that is, the ratio of the currently used bandwidth resource of one FlexE service port to the bandwidth resource allocated to the FlexE service port in step 102 is referred to.
In this step, it is monitored that the bandwidth utilization rate of the FlexE service port to which the second part of bandwidth resources are allocated is smaller than the set bandwidth threshold, which indicates that the FlexE service port can also normally forward the current service traffic using the bandwidth resources allocated in step 102. And recovering the second part of bandwidth resources allocated to the Flexe service port, and adding the recovered second part of bandwidth resources to the shared bandwidth for continuous use when other Flexe service ports are congested.
It can be seen that, in the technical solution provided in the embodiment of the present application, for a FlexE service port whose bandwidth utilization rate is less than a set bandwidth threshold and to which a second part of bandwidth resources are already allocated, the allocated second part of bandwidth resources in the FlexE service port can be timely recovered, and the recovered second part of bandwidth resources are added to the shared bandwidth, so that the FlexE service port is reallocated and used when congestion occurs in forwarding service traffic, and the bandwidth utilization rate of the total bandwidth corresponding to the FlexE Group is further improved, thereby further improving the rationality of bandwidth allocation.
As another example, as shown in fig. 3, after step 1032, the method further includes the following step 1034:
It should be noted that the bandwidth utilization rate of this step is the same as the above-described determination method of the bandwidth utilization rate.
In this step, it is monitored that the bandwidth utilization rate of the FlexE service port existing in the FlexE service port to which the third part of bandwidth resources is allocated is smaller than the set bandwidth threshold, which indicates that the FlexE service port having the bandwidth utilization rate smaller than the set bandwidth threshold can normally forward the current service traffic using the bandwidth resources allocated in step 102. Based on the above, the third part of bandwidth resources allocated to the FlexE service ports are recovered, and the recovered third part of bandwidth resources are added to the shared bandwidth to be used continuously when other FlexE service ports are congested.
It can be seen that, in the technical solution provided in the embodiment of the present application, for a FlexE service port whose bandwidth utilization rate is less than a set bandwidth threshold and to which a third part of bandwidth resources are allocated, the allocated third part of bandwidth resources in the FlexE service ports can be timely recovered, and the recovered third part of bandwidth resources are added to the shared bandwidth, so as to be reallocated and used when congestion occurs in service traffic forwarded by the FlexE service port, so that the bandwidth utilization rate of the total bandwidth corresponding to the FlexE Group is further improved, and further the rationality of bandwidth allocation can be further improved.
The flow shown in fig. 1 to 3 is described below based on an embodiment:
for convenience of description, the network device is a network device applied to the FlexE technology, and the network device includes three physical ports, which are respectively denoted as a physical port a, a physical port B, and a physical port C, and the bandwidth resource configured for the physical port a is 60G, and the bandwidth resource configured for the physical port B and the physical port C is 50G, so that the total bandwidth resource configured for the three physical ports is 170G, the three physical ports form a FlexE group, and the service types are set to include a video type, a voice type, and a short message type according to the service types to which the services belong and according to the requirements of users for forwarding services, so that the three service types correspond to the three FlexE service ports, one of the three FlexE service ports is used for setting and forwarding the video type service, one is used for forwarding the voice type service, and the other is used for forwarding the short message type service. And the FlexE group binds the three FlexE service ports, so that a mapping relationship is formed between the third physical port of the FlexE group and the three FlexE service ports, and service streams forwarded by the three FlexE service ports are all mapped to the three physical ports for forwarding.
Taking 5G as a basic bandwidth, the network device selects bandwidth resources which are 5 times as shared bandwidth from 170G corresponding to the FlexE group configured by the network device, for example, 70G is determined as shared bandwidth; determining a service influence factor of each Flexe service port according to the importance degree of service type forwarding of each Flexe service port, setting the service influence factor of the Flexe service port for forwarding video services to be 0.5, the service influence factor of the Flexe service port for forwarding voice services to be 0.3, the service influence factor of the Flexe service port for forwarding short message services to be 0.2, allocating 50G from 100G to the Flexe service port for forwarding video services, allocating 30G from 100G to the Flexe service port for forwarding voice services, allocating 20G from 100G to the Flexe service port for forwarding short message services, wherein 100G is determined by subtracting 70G of shared bandwidth from 170G corresponding to Flexe group.
Monitoring the bandwidth utilization rates of the three FlexE service ports, and when monitoring that the bandwidth utilization rate of only one FlexE service port of the three FlexE service ports exceeds the set bandwidth threshold, where the bandwidth utilization rate is the ratio of the bandwidth resource used by the current service traffic of one FlexE service port to the bandwidth resource allocated to the FlexE service port, for example, the bandwidth resource used by the current video traffic of the FlexE service port forwarding the video-class service is 62G, and the bandwidth resource allocated to the FlexE service port is 50G, then the bandwidth utilization rate of the FlexE service port is 62/50 × 100% × 124%, and similarly, setting the bandwidth resource used by the current voice traffic of the FlexE service port forwarding the voice-class service as 15G, and the bandwidth resource allocated to the FlexE service port as 30G, then the bandwidth utilization rate of the FlexE service port is 15/30% × 100%, (50%), and setting the bandwidth utilization rate used by the FlexE service port forwarding the short message-class service as 10G, and the bandwidth resource allocated to the FlexE service port is 20G, the bandwidth utilization rate of the FlexE service port is 10/20 × 100% — 50%. The bandwidth threshold is preset, in order to avoid congestion, the FlexE service port for forwarding the video service is set to 90%, the bandwidth threshold corresponding to the FlexE service port for forwarding the voice service stream is set to 95%, the bandwidth threshold corresponding to the FlexE service port for forwarding the short message service stream is set to 100%, based on the determined bandwidth utilization rates of the respective FlexE service ports, it can be known that only the bandwidth utilization rate of the FlexE service port for forwarding the video service is greater than 90% corresponding to the FlexE service port, the bandwidth resource (62G) required by the FlexE service port for forwarding the current video traffic minus the allocated bandwidth resource (50G) is equal to the bandwidth resource (12G) to be allocated, and 5G is used as the basic bandwidth resource, then, at least, 15G needs to be selected from 70G as the second part of resources to allocate the bandwidth resource to the FlexE service port, and 15G is assigned to the FlexE service port. And continuously monitoring the bandwidth utilization rate of each Flexe service port, and when the bandwidth utilization rate of the Flexe service port for forwarding the video service is monitored to be less than 90% of the set bandwidth utilization rate, recovering the 15GG allocated in the Flexe service port, and adding the recovered 15G into the shared bandwidth, wherein the shared bandwidth has 70G for the use when service congestion occurs in the Flexe service port.
When the bandwidth utilization rate of the Flexe service port for forwarding the voice service and the bandwidth utilization rate of the Flexe service port for forwarding the video service in the three Flexe service ports are monitored to exceed the set bandwidth threshold, determining the service influence factors of the two Flexe service ports, setting the service influence factor of the Flexe service port for forwarding the video service to be greater than the service influence factor of the Flexe service port for forwarding the voice service, preferentially distributing bandwidth resources for the Flexe service port for forwarding the video service from the shared bandwidth 70G, setting that the Flexe service port for forwarding the video service needs 120G for statistics on the current service flow, and considering that the Flexe service port for forwarding the video service is configured with 50G, if 70G needs to be allocated to the FlexE service port from 70G, it indicates that the bandwidth resources in the shared bandwidth have been completely allocated, and bandwidth resources cannot be allocated to the FlexE service port for forwarding the voice service from the shared bandwidth. If it is monitored that 80G is needed for forwarding the current service flow through a FlexE service port for forwarding the video service and 60G is needed for forwarding the current service flow through a FlexE service port for forwarding the video service, 30G is configured for the FlexE service port for forwarding the voice service in view of 50G being configured for the FlexE service port for forwarding the video service, 30G is selected from 70G as a third part of bandwidth resources to allocate bandwidth resources to the FlexE service port for forwarding the video service, and 30G is added to the FlexE service port allocated to the FlexE service port, it can be seen that the bandwidth resources in the shared bandwidth also store 40G, and based on this, 30G is selected from 40G as the third part of bandwidth resources to allocate bandwidth resources for the FlexE service port forwarding the voice service, and adding 30G to the Flexe service ports until all the Flexe service ports with the bandwidth resources smaller than the bandwidth threshold value are allocated. And continuously monitoring the bandwidth utilization rate of each Flexe service port, and when the bandwidth utilization rate of the Flexe service port for forwarding the video service is monitored to be less than 90% of the set bandwidth utilization rate, recovering the allocated 30G in the Flexe service port, and adding the recovered 30G into the shared bandwidth, wherein the shared bandwidth has 40G for the use when service congestion occurs in the Flexe service port.
Thus, the description of the embodiments is completed.
The following describes the apparatus provided in the present application:
referring to fig. 4, fig. 4 is a schematic structural diagram of a bandwidth distribution apparatus 400 provided in the present application.

and when the bandwidth utilization rate of the Flexe service port existing in the Flexe service port allocated with the third part of bandwidth resources is monitored to be smaller than the set bandwidth threshold, recovering the allocated third part of bandwidth resources in the monitored Flexe service port, and adding the recovered third part of bandwidth resources to the shared bandwidth.
Thus, the apparatus shown in fig. 4 is completed.
It can be seen that, in the technical solution of the embodiment of the present application,
when monitoring that the bandwidth utilization rate of at least one Flexe service port exceeds the set bandwidth threshold, the network equipment selects the bandwidth resources allocated to each Flexe service port from the pre-reserved shared bandwidth and correspondingly allocates the bandwidth resources to each Flexe service port. Therefore, each Flexe service port is not limited by the set bandwidth threshold, even if the service flow exceeds the allocated bandwidth resource, the reserved shared bandwidth can be dynamically called to relieve the packet loss problem caused by service flow congestion, and meanwhile, the bandwidth utilization rate of the total bandwidth corresponding to the Flexe Group can be improved, and further the reasonability of bandwidth allocation can be improved.
