In IPTV (Internet Protocol Television or Interactive Personal TV) system, IPTV live multicast saves a lot of CDN resources and bandwidth, while OTT live services are currently served in unicast. Therefore, operators want to combine OTT live broadcast with a new multicast technology to provide OTT multicast capability to cope with the high concurrency of OTT live broadcast and the requirement of large traffic, and especially, the OTT service that is very effective to cope with the traffic tides of various live broadcast and network red live broadcast has a different feature compared with the traditional IPTV service: OTT Content providers, in addition to conventional CPs (Content Provider), have a large number of internet CPs, which are basically non-subscribed Content Provider users for operators, and they need Content distribution channels of operators to provide services to final viewers at any time. For non-subscribers, operators cannot allocate service resources and configure scheduling policies to such subscribers in advance in a traditional video service manner.
The embodiment of the invention provides a service resource distribution method and a video service system of a non-subscription content provider, which can reduce the flow tidal impact effect of operators, reduce the operation and maintenance cost and provide differentiated business services for different users.
Embodiments of the present invention will be further described below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a block diagram of a video service system according to an embodiment of the present invention. The video service system mainly comprises a multicast service system deployed in a service layer, a BIER network system deployed in a network layer and a multicast proxy deployed in a terminal, wherein the multicast service system comprises DPI equipment, a multicast service management platform and a multicast server, and the whole network is deployed on a system side to perform centralized management on multicast services; the Bier network system includes BFIR (Bit-Forward Ingress Router, ingress router), BFER (Bit-Forward Egress Router, egress router) and Bier controller, wherein:
multicast service management platform: the main functions include configuring and managing preset switching conditions of the unicast switching group; managing multicast agents including log-in, heartbeat, etc.; maintaining a multicast channel list; sending a multicast switching instruction to a multicast server and a multicast proxy; interacting with BIER controller to manage multicast channel, BFER, BFIR correspondence, etc.;
the multicast server: acquiring multicast channel information and creating a multicast physical channel; unicast-to-multicast and transmitting multicast media data; unicast retransmission supporting multicast agents, etc.;
bier network system: based on the original BIER network, a BIER controller is added and is in charge of communication connection with a multicast service system so as to synchronize the information of BIER equipment; wherein,
and (3) a terminal: a multicast proxy is deployed, multicast channel description information is obtained from a multicast server, and corresponding multicast information is analyzed; supporting the terminal to join the multicast group; receiving a multicast data packet from the BFER; supporting multicast to unicast; support unicast retransmission requests, etc.
Referring to fig. 2, an embodiment of the present invention provides a service resource distribution method of a non-subscription content provider, which is applied to the video service system as shown in fig. 1, and may include, but is not limited to, steps S210 to S250, wherein:
step S210: responding to a service request from a terminal, and providing unicast service by a CDN service node;
step S220: the multicast service management platform hives the service request through DPI equipment, and performs service analysis on the service request according to a preset filtering strategy to obtain service information;
step S230: when the service information meets a preset switching condition, the multicast service management platform sends multicast switching information to the multicast server so that the multicast server creates a multicast channel;
step S240: the multicast service management platform acquires multicast channel information from the multicast server and sends a multicast switching instruction and the multicast channel information to the terminal so that the terminal starts the multicast proxy;
step S250: the multicast proxy joins the multicast group of the multicast channel.
The service request of the terminal is subjected to service analysis, whether preset switching conditions are preset or not is judged according to the obtained service information, if yes, a multicast channel is created by the multicast server, the terminal is informed to start a multicast proxy, the multicast proxy joins a multicast group of the multicast channel, centralized multicast capacity is provided, the flow tidal impact effect of operators can be reduced, the operation and maintenance cost is reduced, differentiated service is provided for different users, the operation cost of a large number of users can be saved, and the satisfaction degree of the users is improved.
Referring to fig. 3, in the service resource distribution method described above, in response to a service request from a terminal in step S210, the CDN service node provides a unicast service, which may include, but is not limited to, steps S310 to S320:
step S310: the dispatching center obtains a service request from a terminal and dispatches the service request to a CDN service node according to a load balancing dispatching strategy;
step S320: the CDN service node provides unicast service.
It can be understood that before the preset switching condition is met, the video service system still adopts a unicast mode to provide services, so that the waste of multicast resources is avoided.
The service resource distribution method further comprises the following steps: and when the terminal starts the multicast proxy, the multicast proxy performs authentication registration to the multicast service management platform.
It should be noted that, the multicast proxy performs authentication registration to the multicast service management platform to ensure validity of the multicast proxy, and after successful registration, the multicast proxy joins the multicast group of the multicast channel.
In the service resource distribution method, after the multicast proxy joins the multicast group of the multicast channel, the multicast proxy and the multicast service management platform keep hot-active processing through heartbeat messages.
Referring to fig. 4, in the above-described service resource distribution method, steps S410 to S430 may further include:
step S410: the multicast service management platform acquires BFER information of the terminal reported by the multicast proxy and synchronizes the BFER information to the BIER controller;
step S420: the BIER controller updates a distribution link of a BIER network according to the BFER information, and distributes a BFIR entry address to the multicast service management platform;
step S430: and the multicast service management platform updates the mapping relation of the multicast channel, the BFIR and the BFER according to the BFIR entry address.
It can be understood that after the multicast proxy joins the multicast group, the BFER information of the terminal is reported to the multicast service management platform, and the multicast service management platform synchronizes the BFER information to the BIER controller, so as to tell the BIER controller that a new terminal user needs to join in the distribution link of the BIER network, thereby updating the distribution link of the BIER network and updating the mapping relationship of the multicast channel, the BFIR and the BFER, and enabling the terminal user newly joining the BIER network to normally acquire the multicast media stream.
Referring to fig. 5, in the above-mentioned service resource distribution method, the BIER controller in step S420 updates a distribution link of a BIER network according to the BFER information, which may include, but is not limited to, steps S510 to S520:
step S510: the BIER controller synchronizes the BFER information to a corresponding BFIR;
step S520: and the BFIR updates and distributes the BitString strings, floods the whole network nodes of the BIER network, and updates and distributes links.
Referring to fig. 6, in the above-described service resource distribution method, steps S610 to S640 may further be included:
step S610: the multicast service management platform synchronizes the mapping relation to the multicast server;
step S620: the multicast server obtains a unicast media stream from the CDN service node, multicasts the unicast media stream into a multicast media stream, sends the multicast media stream to a corresponding BFIR and sends a multicast service starting notice to the multicast proxy through the multicast service management platform;
step S630: the BFIR distributes the multicast media stream to the corresponding BFIR in the BIER network according to the distribution link;
step S640: and the multicast proxy acquires the multicast media stream from the BFER after receiving the multicast service start notification.
Referring to fig. 7, in the above-described service resource distribution method, steps S710 to S720 may further be included:
step S710: the multicast proxy synchronizes the frames of the multicast media stream with the frames of the unicast media stream;
step S720: when the frames of the multicast media stream are completely synchronous with the frames of the unicast media stream, the multicast proxy sends a unicast stopping notification to the terminal so that the terminal stops acquiring the unicast media stream from the CDN service node.
The service resource distribution method may further include:
and the multicast proxy responds to the multicast service request of the terminal, converts the multicast media stream into a unicast media stream and sends the unicast media stream to the terminal for decoding and playing.
In the foregoing service resource distribution method, the multicast server obtains a unicast media stream from the CDN service node, including one of the following two ways:
the multicast server performs stream pulling of unicast media streams to the CDN service node;
and the CDN service node performs push flow of the unicast media stream to the multicast server.
In the service resource distribution method, the service information includes at least one of a user quantity, a bandwidth occupation quantity and a bandwidth change trend; the preset switching conditions correspondingly comprise at least one of the following:
the user quantity is larger than a first preset value;
the bandwidth occupation amount is larger than a second preset value;
the bandwidth occupancy rate continuously rises within a preset duration.
It can be understood that when the user quantity is greater than the first preset value, that is, a certain number of terminals obtain services in a unicast manner, a great amount of network bandwidth of CDN resources is consumed, tide phenomenon is easily caused, and daily operation and cost of operators are seriously affected; similarly, when the bandwidth occupation amount is larger than a second preset value, the tide phenomenon is easy to cause, so that the unicast service needs to be switched to the multicast service, the flow tide impact effect of an operator is reduced, the operation and maintenance cost is reduced, and differentiated service services are provided for different users; similarly, the bandwidth occupancy continues to rise for a preset period of time, indicating that tidal phenomena may have been induced, thus requiring a switch from unicast service to multicast service, reducing the traffic tidal impact effect of the operators.
In addition, the embodiment of the invention also provides a video service system, which comprises a multicast service management platform and a multicast server which are deployed on a service layer and a multicast proxy which is deployed on a terminal, wherein:
the multicast service management platform is used for: the service request sent to the dispatching center by the terminal is hijacked by DPI equipment, and the unicast service provided to the terminal by the CDN service node is subjected to service analysis according to a preset filtering strategy to obtain service information; when the service information meets a preset switching condition, sending multicast switching information to the multicast server so that the multicast server creates a multicast channel; acquiring multicast channel information from the multicast server and sending a multicast switching instruction and the multicast channel information to the terminal so that the terminal starts the multicast proxy;
the multicast server is used for creating a multicast channel and sending multicast channel information to the multicast service management platform;
the multicast proxy is used for carrying out authentication registration on the multicast service management platform, and after the registration is successful, the multicast group joining the multicast channel and the multicast service management platform keep hot-alive processing through heartbeat messages.
It can be understood that, for other functions and roles of each component in the video service system provided by the embodiment of the present invention, reference may be made to each embodiment provided in fig. 1 to fig. 7, and the video service system provided by the embodiment of the present invention and the service resource distribution method provided by the embodiment of the present invention belong to the same invention communication, so that other functions and roles of each component in the video service system are not repeated herein.

It can be appreciated that the BFIR (Bit Index Explicit Replication ) technique provides a stateless multicast forwarding mechanism, where a multicast head node BIER (Router Bit-Forward Ingress Router, ingress route) generates a forwarding BS (BitString) according to multicast receiver BFER (Bit-Forward Egress Router, egress Router) information, and distributes the forwarding BS according to Bit operations of the BS, without maintaining any multicast stream forwarding state information (Group, ingress, egress), and a BIER link state library is generated by BIER extension flooding of IGP (ISIS/OSPF) protocol.
The embodiment of the invention provides a video service in a centralized multicast mode under a non-subscription scene based on a Bier technology. Under the non-signed CP, in order to facilitate unified management and reduce resource consumption of the client, the server performs centralized unified management on the multicast distribution time and strategy:
1) And (3) hijacking the service request for the play request of the user through a beam splitter DPI (Deep Packet Inspection ), mirroring the service request to a multicast service management platform, carrying out service analysis and statistics on hot content information by the multicast service management platform according to a preset filtering strategy (such as CPID, service type, user request protocol type and the like), and then judging whether to carry out unicast and multicast switching according to a preset switching strategy (such as user quantity, bandwidth occupation quantity, bandwidth change trend and the like).
2) When the preset switching condition of the unicast-multicast switching is reached, the multicast service system performs unicast-multicast pulling switching by informing the client on one hand, interacts with the BIER controller on the other hand, synchronizes the BFER information corresponding to the user to the BIER controller, informs the BFIR to update BS (BitString) and refresh the distribution link information, and the multicast server pushes the unicast media stream to the BFIR.
3) BFIR receives the multicast media stream and then forwards the multicast media stream in the BIER network according to the BS string value;
4) The terminal joins the multicast group of the multicast channel of the CP, pulls the multicast media stream to BFER, and converts the multicast media stream into a unicast media stream through the multicast proxy, and the terminal decodes and plays the unicast media stream.
In the existing video service system, the operator only needs to carry out protocol upgrading on related router equipment in the network to support the Bier technology, the server newly deploys a multicast service management platform and a multicast server, and a multicast agent is installed in the terminal to realize the method, so that the cost is low and the management is easy.
The service resource distribution method provided by the embodiment of the invention can be applied to novel Internet high-flow live broadcast services under a non-signed CP scene, such as network red live broadcast, conference live broadcast, live broadcast with goods and the like. In the non-signed direct broadcast CP scene of a large number of Internet, due to sporadic service characteristics and concurrent requests of a large number of users at any time and any place, great impact can be brought to the flow of an operator network, and the tide phenomenon is obvious. In order to reduce the influence of novel live broadcast services on the current network service and the network, the prior unicast distribution is optimized into a mode of combining unicast and multicast, according to the real-time condition of the user quantity, a video service system automatically decides unicast or multicast, meanwhile, multicast distribution based on the Bier technology can completely decouple application and transmission, the real multicast forwarding of a network layer is realized, the service characteristics of the network layer do not need to be concerned, the cost of multicast maintenance and management is further reduced, and the multicast distribution efficiency is improved.
