Description
Technical field
The present invention relates to the network communications technology, relate in particular to a kind of application layer multicast system and streaming medium data processing method.
Background technology
Stream media technology is that a kind of this technology makes the user can watch program while downloading with the stream transmission mode technology of multi-medium data such as audio plays, video on the internet, does not watch after not needing whole file downloaded again.The develop rapidly of the network bandwidth is used the solid network foundation that provides for Streaming Media, and wherein, net cast is one of emphasis of Streaming Media application.The system of carrying net cast business mainly contains client/server (Client/Serves on the Internet at present; Abbreviate as: C/S) pattern, content distributing network (Content Delivery Network; Abbreviate as: CDN) pattern and peer-to-peer network (Peer to Peer; Abbreviate as: P2P) pattern.
Wherein, Fig. 1 is a kind of structural representation of existing C/S framework.Comprise server 11 and a plurality of and server 11 direct-connected clients 12 in C/S structure shown in Figure 1.In the C/S framework, in the face of the stream media live service in the Internet time, server 11 is all set up a link that sends stream medium data for the client 12 of each request stream media live service.In this pattern, if there are a plurality of clients 12 to ask same stream media live service simultaneously, then will there be many parts of identical stream medium datas on the internet.
Fig. 2 is a kind of structural representation of existing CDN system.As shown in Figure 2, this CDN system is a virtual network of setting up and covering on the Internet, be made of the node server group 23 who is made of a plurality of node servers 21 who is distributed in zones of different, wherein, each node server 21 stores identical stream medium data, and is connected with a plurality of clients 22.This CDN system mainly is by a plurality of node server 21 configuration node server zones, avoids may influencing on the Internet bottleneck and the link of data transmission bauds and stability, and the assurance client can be obtained required content nearby, reduces response delay.
The P2P network is different from the network of C/S model, is a kind of distributed network.In the P2P network, share the part resource that has between each node each other, each node is the server in the C/S model, is again the client in the C/S model.The P2P network mainly is to cooperate to alleviate load of server by the active between each node.
But, for high definition, real-time, large-scale net cast business, above-mentioned variety of network systems all exists not enough in realization: if adopt the system of C/S model to carry, because the data volume of net cast business is bigger, heavier to load of server, there is the problem that system that server itself brings can't dilatation; In addition, many parts of identical stream medium datas transmit in the Internet simultaneously, will take a large amount of network bandwidths, cause the waste of the network bandwidth, namely C/S model and be not suitable for carrying high definition, in real time, large-scale net cast business.In like manner, the C/S framework grows up because the CDN system is based on, and therefore, has the problems referred to above equally, namely the CDN system also be not suitable for carrying high definition, in real time, large-scale net cast business.For the P2P network, be based on asynchronous sharing owing to pass data between the client mutually, be certain P2P client-requested certain live broadcast service data may from other P2P clients of oneself watching this live broadcast service simultaneously, may not watch this live broadcast service from other yet but store the P2P client of part live broadcast service data, this just can't satisfy live broadcast service to the requirement of synchronism (being real-time), and namely the P2P network also is not suitable for carrying high definition, real-time, extensive net cast business.
A kind of application layer multicast technology has appearred in the variety of issue based on current carrying high definition, real-time, extensive net cast business face.Application layer multicast is by copying in application layer and data cached bag, rather than duplicate packet is avoided the deployment issue of network layer multicast (being the IP multicast) on router.Node in the application layer multicast net is the multicast member main frame, the route of stream medium data, copy, function such as forwarding all finished by the multicast member main frame; Set up and safeguard an overlay network at the multicast member main frame based on self-organized algorithm.Application layer multicast has been inherited the communication efficiency of multicast pattern, has overcome the shortcoming that IP layer multicast is difficult to carry out in Internet, has for example solved the variety of issue that C/S, CDN occur when professional in the face of high definition, real-time, extensive net cast.
Fig. 3 is for having the structural representation of the flow media distribution system of realizing based on the application layer multicast technology now.This system comprises: centre point server 35, a plurality of Edge Servers 31 that are connected with centre point server 35, the Request Routing Server for Peer to Peer 33 that is connected with Edge Server 31 and the P2P client 34 that is connected with Edge Server 31, and each the P2P client 34 that is in the autonomous territory also is connected to each other.This system utilizes the upload ability of P2P client 34 to transmit a part of stream medium data mutually, thereby has saved the consumption of centre point server 35 resources by making up the autonomous territory of P2P client, has reduced the load capacity requirement to centre point server 35.But, are asynchronous sharing owing to transmit data mutually between the P2P client, still can't satisfy the net cast business to the requirement of real-time.
