Description
Technical field
The present invention relates to Internet technical field, relate in particular to a kind of controllable multicast system based on multicast conversion.
Background technology
The high-performance Video transmission system (comprising video conferencing system and network television system) with technical characterstics such as big data quantity, low delays is typical case's application of Next Generation Internet, and this application itself has proposed very high request to aspects such as the network bandwidth and real-times to network, end system and application system.Popular Video Applications system comprises DVTS system, VLC system and high definition non-compression video system at present, resolution is from SD (720 * 480) to high definition (1920 * 1080), transmission bandwidth is from 22Mbps to 800Mbps, there is different characteristics, for the different demand of user provides different services.High-performance Video transmission system generally has a point-to-multipoint or how point-to-multipoint concurrent transmission characteristic, due to reasons such as port speed constraint, network congestions, current the Internet differs and meets surely Video transmission system requirement for bandwidth under concurrent multiplexing scene.Before this, the method of the unspecial solution network problem for Video transmission system, traditional transmission method based on clean culture, under concurrent multiplexing scene, consume network bandwidth seriously, and may be because of excessive network congestion and the packet loss of causing of number of concurrent, each road transmission performance is all affected.
On the basis of IPv6 internet architecture of new generation; Any-Source Multicast (Any Source Multicast; ASM) and specific source multicasting (Source Specific Multicast; SSM) technology is in order to the data-message transmission service of a kind of one-to-many and multi-to-multi to be provided in network layer, to guarantee that the data redundancy in the Internet reduces as far as possible.On the link of a plurality of copies that originally sent datagram, ASM multicast and SSM multicast, by specific method for routing, are restricted to only individual data message by the data message sending on this link, thereby strictly control data redundancy.Yet because model, agreement and routing mode are different, ASM multicast and SSM multicast can not be compatible, and clean culture and multicast can not be compatible.
In ASM multicast and SSM multicasting technology, the source of multicast, recipient and bandwidth are all uncontrollable, and when user node adds continually and exits, the state of Multicast Routing will change continually in addition, cause great state-maintenance expense, seriously affect the extensibility of multicast services.Therefore, how to guarantee controllability and the fail safe of multicast services, and how to reduce extensibility that multicast state changes to improve multicast services be one of multicast services key technology of being used widely.

The configuration of described channel information comprises: network manager is configure channel 1 and channel 2 in gateway topological database, respectively source address is set to the address of user side u1 and user side u2, and fills in two group address and bandwidth, title and profile information that channel is corresponding.
S2: start respectively each transfer gateway and register to network management system;
Be specially: ASM and SSM multicast bi-directional conversion gateway and clean culture and SSM multicast bi-directional conversion gateway start respectively, to network management system, apply for the registration of, the port numbers that network management system provides forwarding to take, ASM and SSM multicast bi-directional conversion gateway and clean culture and SSM multicast bi-directional conversion gateway check after the idle port of self, submit to unique gateway name, IP address, available forwarding address and the port list of the overall situation of gateway self to complete registration, network management system determines that gateway reaches the standard grade.
S3: network management system is respectively each transfer gateway and calculates forwarding list and forwarding list is sent to corresponding transfer gateway;
Be specially: network management system is that online ASM and SSM multicast bi-directional conversion gateway and clean culture and SSM multicast bi-directional conversion gateway calculate respectively forwarding list, and described forwarding list correspondence is sent to ASM and SSM multicast bi-directional conversion gateway and clean culture and SSM multicast bi-directional conversion gateway;
Wherein:
The forwarding list of clean culture and SSM multicast bi-directional conversion gateway comprises: < (u1 address, clean culture and SSM multicast bi-directional conversion gateway address), the group address of channel 1, port numbers 1, the bandwidth > of channel 1 and < (ASM and SSM multicast bi-directional conversion gateway address, the group address of channel 2), the address of u1, port numbers 2, the bandwidth > of channel 2;
The forwarding list of ASM and SSM multicast bi-directional conversion gateway comprises: < (u2 address, ASM address 2), the group address of channel 2, port numbers 2, the bandwidth > of channel 2 and < (clean culture and SSM multicast bi-directional conversion gateway address, the group address of channel 1), ASM address 1, port numbers 1, the bandwidth > of channel 1.
S4: user side sends data by the forwarding service of corresponding conversion gateway to another user side;
Be specially: user side u1 sends unicast data to clean culture and SSM multicast bi-directional conversion gateway, user side u2 sends ASM multicast packet to ASM and SSM multicast bi-directional conversion gateway, clean culture and SSM multicast bi-directional conversion gateway and ASM and SSM multicast bi-directional conversion gateway forward respectively operation, and user side u1 and user side u2 receive respectively the other side's data.
S5: network management system obtains the running state information and traffic statistics information writing information staqtistical data base of this transfer gateway from transfer gateway;
Be specially: network management system is sent traffic statistics order to transfer gateway, after receiving this order, transfer gateway takies situation to up-to-date CPU, internal memory and the gateway of network management system report transfer gateway, and gateway respectively forwards the real-time bandwidth information of channel etc., as: the average CPU in time in the past takies, on average EMS memory occupation, average bandwidth take, and each forwards channel average bandwidth corresponding to tuple.
S6: keeper checks the statistics in described Information Statistics database by network management system;
Be specially: network manager accesses the web services of network management system, online situation and the converting flow historical record of inquiry clean culture and SSM multicast bi-directional conversion gateway and ASM and SSM multicast bi-directional conversion gateway, the information such as the flow historical record of two channels, grasp the running status of extensive controllable multicast system.If there is gateway roll off the production line, that channel sends unsuccessfully etc. is abnormal, can find the reason of problem by this web services.
The forwarding service of described transfer gateway comprises reception data and is forwarded to corresponding destination address, and the data that receive are carried out to flow control.
The present invention, by the collaborative work of many multicast transfer gateways, supports complicated network environment and multicast to support situation.The multicast transmission mode of end-to-end can change repeatedly, is responsible for coordinating each transfer gateway carries out relay conversion by network management system.Can realize extensive controllable multicast system, support the collaborative work of multiple multicast model, under a framework, solve the controlled and scalability problem of multicast.
Above execution mode is only for illustrating the present invention; and be not limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
