Abstract
The invention discloses a session initiation protocol-based peer-to-peer connection method of a peer-to-peer network and a peer-to-peer body. The method comprises the following steps that: a first peer-to-peer body receives a connection message carrying destination identification sent by a second peer-to-peer body, and the destination identification is used for indicating the type of a peer-to-peer body with which the connection message allows to connect; and the first peer-to-peer body establishes connection with the second peer-to-peer body after determining that the type of the peer-to-peer body is identical to the type indicated by the destination identification in the connection message. By indicating the type of a peer-to-peer body allowed to be connected with by the destination identification of a connection message, the peer-to-peer connection method ensures that a peer-to-peer body receiving a connection message determines whether self type is identical to the type indicated by the destination identification in the connection message according to the destination identification; if the types are identical, connection processing is carried out according to the connection message; and if the types are different, connection processing is terminated, so that the establishment of error network communication and unnecessary ICE interaction caused thereby are avoided.
Description
Technical field
The present invention relates to network communications technology field, relate in particular to a kind of peer-to-peer method of attachment and peer-to-peer of peer-to-peer network of dialogue-based initiation protocol.
Background technology
SIP (session initiation protocol) is a kind of application layer control protocol, and it can be used to create, revises or stop Multimedia session.The plurality of advantages such as SIP is simple by means of it, be easy to expand, be convenient to realize more and more obtain the favor of industry, and it just progressively becomes the important protocol in NGN (next generation network) and the 3G multimedia subsystem domain.
The weakened concept of server of P2P (Peer-to-peer equity) network, thousands of node all is the identical resource provider in status and requestor in the network, has the relation of equity between all nodes, node is also referred to as peer-to-peer.The P2P network has the advantages such as self-organizing, zmodem, extensibility be strong, becomes to represent the next generation network key technology in future.
At present, researcher in the industry makes its performance advantage separately in the combination of exploring research and development SIP and P2P network.In the peer-to-peer network (P2PSIP network) of dialogue-based initiation protocol, each peer-to-peer is assigned with a peer identification, and peer identification is used for unique identification peer-to-peer on the P2PSIP network.The resource distribution of P2PSIP network is stored on each peer-to-peer, and each resource is specified by unique resource identification.In a peer-to-peer space, its peer identification of peer-to-peer of the resource identification of resource and storage equates, and when certain peer-to-peer deviated from network, the resource of storing on this peer-to-peer is just taken over responsible by other peer-to-peers of being responsible for this resource.Resource distribution just because of the P2PSIP network is stored on each peer-to-peer, and constantly there is peer-to-peer to add dynamically and deviated from network, in order to realize the connection between the peer-to-peer in the P2PSIP network, new connection message is defined to finish ICE (interactive connectivity) and detects the mutual of address information between needed peer-to-peer.
As shown in Figure 1, take peer-to-peer A, the peer-to-peer B of P2PSIP network, peer-to-peer C, peer-to-peer D as example, a typical connection message handling process is described: at first, shown in step 11, peer-to-peer B periodically upgrades it routing table information notice peer-to-peer A by Update (updating message), peer-to-peer A transmits the routing table information of coming according to peer-to-peer B, judges that peer-to-peer C should join in the routing table of peer-to-peer A as new neighbor; Then, peer-to-peer A sends connection message, the resource identification of connection message is set to the peer identification of peer-to-peer C, peer-to-peer C is on the P2PSIP network, peer-to-peer C connection message route sends on the peer-to-peer C shown in step 12, namely receive this connection message, peer-to-peer C processes the address information mutual (shown in step 13) that this connection message is finished peer-to-peer A and peer-to-peer C; At last, peer-to-peer A sets up between peer-to-peer with peer-to-peer C startup ICE process and directly is connected.
In realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art:
Because the neighborhood of P2PSIP network is kept by Keepalive (alive message), but Update and keepalive are two independently processes, therefore, when peer-to-peer B sent its routing table information to peer-to-peer A, the uncertain peer-to-peer C one of peer-to-peer B fixed on the P2PSIP network.As shown in Figure 2, peer-to-peer A sends connection message, the resource identification of connection message is set to the peer identification of peer-to-peer C, peer-to-peer C is not on the P2PSIP network, suppose that peer-to-peer D is responsible for taking over the resource on the peer-to-peer C, then the connection message route sends on the peer-to-peer D shown in step 12, be that peer-to-peer D receives this connection message, peer-to-peer D processes the address information mutual (shown in step 14) that this connection message is finished peer-to-peer A and peer-to-peer D, therefore, caused wrong peer address information interaction and unnecessary ICE is mutual afterwards.
So the connection message of above-mentioned structure is only set up connection between the peer-to-peer by resource identification, not necessarily need the peer-to-peer that connects so that receive the peer-to-peer of this connection message, the network service that leads to errors and follow-up unnecessary ICE are mutual.
