Description
Technical Field
The invention relates to the field of computer networks, in particular to a method and a device for scheduling bandwidth resources.
Background
With the strategic advance of 'broadband China' and the development of 'Internet +', the demand of enterprises on the Internet basic network is higher and higher.
At present, operators adopt 95 strategy charging for basic network bandwidth services (all bandwidth values are taken out, the highest value is removed, and the remaining maximum bandwidth is the charging bandwidth), and the 95 strategy is adopted for charging no matter the conditions of CDN service providers and operators, CDN service providers and bandwidth users, so in the actual process, in order to improve the bandwidth utilization rate, the most common mode is to share the bandwidth. In the internet, and in particular in content distribution networks, a content service is often provided by a plurality of distributed content servers. In order to effectively utilize the resources of all content servers, all access requests to the content need to be dispatched to the content servers in a balanced manner. In the prior art, a traffic scheduling method based on Domain Name System (DNS) resolution is mainly used, and the specific process is as follows:
1. the local DNS receives a request of a client and sends a domain name resolution request to an authoritative domain name server;
2. the authoritative domain name server returns the IP address corresponding to the domain name to the local DNS in equal proportion;
3. and the local DNS returns the IP address to the client, and the client sends a content access request to the corresponding content server according to the returned IP address.
The prior art has the following problems:
1. the fair sharing of services among users cannot be guaranteed, the bandwidth is fully utilized, secondly, no method is available for dynamic and static separation, the phenomenon that some users occupy a large amount of bandwidth due to busy service to influence other services to use the network bandwidth occurs among sharing users achieving dynamic bandwidth reuse, and the sharing effect is poor. 2. The performance differences of the content servers cannot be distinguished. The processing performance of each content server, even the network bandwidth, may be different, and if it is to be ensured that each server can process the traffic allocated to it, the traffic can be allocated according to the server with the worst performance when the equal proportion allocation is adopted, which will result in low utilization rate of the server with better performance.
3. The current operating state of the server cannot be reflected. Some clients may autonomously select a content server, which may result in traffic for this portion of the client not being controlled by the scheduling system. If the DNS load balancing scheduling system distributes other traffic evenly to the individual content servers, the load may be much greater for the content servers accessed by the portion of the request to autonomously select a content server than for the other servers.
In summary, the existing inter-node traffic balancing technology cannot adapt to the actual network situation, the node utilization efficiency is low, the enterprise cost is increased, and the user experience is poor.

In order to solve the above problems, embodiments of the present invention provide a method and an apparatus for scheduling bandwidth resources, where an optimal bandwidth reuse policy is generated by using a relevant optimization mechanism, scheduling is completed according to the bandwidth reuse policy, users in different peak periods of each node are combined with each other to achieve an optimal utilization rate of each node, and the model performs real-time optimization and dynamic adjustment along with service changes. The problems that the existing flow balancing technology between nodes can not adapt to the actual network condition, the node utilization efficiency is low, and the user experience is poor are solved, and the flow balancing between service nodes which is adaptive to the network service bearing condition is realized.
First, a first embodiment of the present invention will be described with reference to the drawings.
The embodiment of the invention provides a bandwidth resource scheduling method, and the flow of completing the balanced scheduling of service flow among nodes by using the method is shown in figure 1, and comprises the following steps:
the bandwidth size data at least comprises any one or more of the following information:
the node identification ID, the average bandwidth per minute of the node, the time point corresponding to the bandwidth and the unique identification code of the user service.
And collecting the unique identification code of the user service, wherein the unique identification code can be used for summarizing the global total bandwidth of the service, and limitation and other strategy processing are required if fluctuation and abnormity occur.
And when the system is initialized, extracting bandwidth scale data of various services corresponding to each user identifier in each service node at the initial time.
The collected bandwidth scale data can be used as a basis for generating a bandwidth multiplexing strategy. The collection can be triggered according to the system requirement to generate a new bandwidth reuse strategy; and the bandwidth reuse strategy can also be obtained by periodic collection and corresponding periodic adjustment.
102, determining a bandwidth multiplexing strategy of each service node according to full-time bandwidth scale data of various services corresponding to each user identifier;
the bandwidth multiplexing strategy comprises the source user identification of the service carried in each time interval and the carried flow.
The method specifically comprises the following steps:
1. determining the bandwidth use conditions of different services in different time periods;
2. analyzing the correlation among the services which can be carried by each service node; and performing correlation analysis through two or more than two service bandwidth models so as to measure the correlation closeness of the bandwidths in the same time, wherein the lower the correlation is, the higher the bandwidth reusability is.
3. The flow generated by the same service is distributed to a plurality of service nodes capable of bearing the service, and the flow occupied by the service on the service node is determined according to the bandwidth use condition of each node in different time periods.
For example, currently, in a Fujian area, there are 10 services of the same type, and there are 3 corresponding nodes, the optimal combination of the three nodes is completed according to the 10 services, where a certain time may be a bandwidth value per minute or 5 minutes, and a time point corresponding to the bandwidth. The method mainly carries out correlation analysis through two variable elements of the bandwidth and the time, so that the maximum use of the bandwidth of a time unit is achieved (each node has an upper bandwidth limit and is changed into an initial node attribute), and the strategy can be periodically adjusted along with the change of the bandwidth of the node.
in this step, when receiving the domain name resolution request, each service node capable of providing the service at the current time point can be determined according to the bandwidth multiplexing policy
And 105, selecting a corresponding number of IP addresses from the corresponding nodes according to the number of the IP addresses of the resolution results provided by each node by the GSLB, and returning the IP addresses as the resolution results to the local DNS.
the resolution result indicates at least two service nodes, each providing at least one IP address.
Preferably, when the online service type changes, the bandwidth reuse policy is adjusted according to the change of the online service type.
If GSLB finds that the traffic carried by a certain service node exceeds the upper limit of the bearer by reporting the summarized data, it triggers a protection mechanism to complete the corresponding bandwidth allocation according to the upper limit (i.e. within the upper limit range). And when the situation exists and the excess flow still exists after the bandwidth allocation is finished, forwarding the excess flow request to the backup strategy. The backup policy may be charged in other manners, such as per-flow charging, with a charging period (e.g., monthly or quarterly). The backup strategy can be adjusted according to the current network load and the network access user condition. And meanwhile, periodically collecting the service and the node bandwidth change condition, and dynamically adjusting and updating the scheduling strategy.
The following is a specific implementation of completing bandwidth resource debugging balance by using the bandwidth resource scheduling method provided by the embodiment of the invention:
after a user client initiates a domain name resolution request, a local DNS finally requests a bandwidth sharing strategy from a GSLB through resolution;
GSLB returns IP analysis result containing sharing strategy to local DNS; the returned result may include the IP in different service nodes, for example, two service nodes, and the allocated bandwidth ratio is 2: 1, when outputting the IP policy, two service nodes will also output the IP policy in a ratio of 2: the number of 1 outputs the IP number, so the final access and traffic distribution will be balanced by the polling access policy of DNS.
GSLB collects feedback information according to actual operation condition, and adjusts existing bandwidth sharing strategy.
After the preliminary scheduling distribution is completed, the nodes can report the information collected by the nodes to the GSLB regularly, the information comprises bandwidth scale data, after the GSLB data center receives the information, the GSLB data center can update and generate a bandwidth scheduling strategy in real time, and when the DNS requests the bandwidth scheduling strategy to be updated.
