1Have special function again, the filling apparatus that its general do as one likes can be better, resource is sufficient is worked as, and that is to say with respect to other common peer-entities in this P2P autonomous networks to have better processor ability, internal memory or storage resources, bigger bandwidth etc.Under this framework, the index function entity in the P2P autonomous networks is responsible for writing down common peer node and static super node S
1On burst information, when a content fragment distributes on a plurality of nodes, the index function entity can (may be by obtaining its bandwidth, processor resource etc. with each node according to certain strategy alternately, determine whether that this node is effective content source) availability of perception burst on each node, and give certain priority to a plurality of nodes that comprise same burst, when other nodes obtain data from peer node like this will according to the priority of index function entity indication (such as, at node S
1Under the enough situation of disposal ability preferentially from node S
1Obtain content, obtain content from other common peer node simultaneously; At node S
1Load when heavier, preferentially obtain modes such as content from peer node) obtain data, the system that makes has higher reliability.Such as, among Fig. 3, node S
1Have better disposal ability and storage capacity, a large amount of content fragments that may distribute above it, when node A wants to obtain certain content fragment in this P2P autonomous networks, the index function entity can tell node A preferentially from super node S
1On obtain.
Framework shown in Figure 4 is introduced under the P2P mechanism pattern necessary in client network, because terminal equipment usually storage and disposal ability a little less than, and it is unstable relatively, require for telecommunications network under the situation of high reliability, need to introduce this super node mechanism and guarantee the user experience that high reliability is become reconciled.
Fig. 5 has described a P2P autonomous networks inside, on the node during burst content change burst index information safeguard flow process.Such as, cause burst increase on its node because the new program of system injects on certain node, or (aging strategy refers to: system can be with the strategy of some content fragment from this knot removal in order to save the space owing to aging strategy.Such as: a month nobody watches the just strategy of deletion according to the program on the node.) coming into force causes on this node some bursts deleted, will trigger this flow process.Node after the index function entity is notified, upgrades the interior content fragment index information of P2P autonomous networks of local maintenance with the burst information notice index function entity that changes.
Fig. 6 has described a P2P autonomous networks inside, and node is to index function entity inquiry burst information flow process.When certain node does not satisfy from user or other node request, can in inquiring about this P2P autonomous networks, the index function entity whether have the content that satisfies request by other node, at this time trigger this flow process.Node sends query requests to the index function entity, the index function entity is received in the content fragment index information of request back in this P2P of local maintenance autonomous networks and is searched, if find then burst information is returned to the initiation node, do not have otherwise notify in its this P2P autonomous networks.
Fig. 7 has described in a P2P autonomous networks inside, P2P transfer process between node.When certain node does not satisfy content requests, whether other node exists the content that satisfies request in the index function entity is inquired about this P2P autonomous networks, the index function entity is received in the content fragment index information of request back in this P2P of local maintenance autonomous networks and is searched, qualified burst index information is returned to the initiation node, after receiving, the node A that initiates to ask sets up data or media transmission channel to each peer node respectively, move data or medium to this node from other peer node, can trigger the flow process of Fig. 5 simultaneously.
