Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
As shown in Figure 1, in the present invention, central server 101 meets data client that transmit to require, that external IP is arranged with network traffics and as the node of instant messaging the instant communication data between the client is carried out transfer transmission, reaches the purpose of saving the transfer server bandwidth thus.Can client become node and be judged by central server 101 and select.
Among the step S101, central server 101 judges that according to the information that client reports whether client possesses the ability of transmission data, is chosen as the node that client provides the data relay service.
Client is regularly to central server 101 reporting equipment environmental information and network traffic informations, facility environment information and network traffic information that central server 101 reports according to client, judge whether client can be used as node and use, and preserve facility environment information, network traffic information and the node signature of node.
Facility environment packets of information includes network device name, the local zone time that client reports to central server 101, whether carried out transmission, CPU information, memory information, local IP and the port (port) etc. of big data quantity such as voice call, video, file.Network traffic information comprises linking number, initiator's request time, channel data bag amount, channel data bag flow etc.Node signature comprises that the key and the term of validity, central server 101 utilize the signature of node to generate a pair of client signature, promptly inserts client signature and destination client and signs, and is used for the identity of node checking client when client inserts; The time that normal connection when the term of validity is the client access node is set up, when the client access node, node is when whether authentication secret is correct, with the term of validity of this machine time contrast key, if overtimely just think that it is invalid signing.
Among the step S102, when needing by node transmission data between client 103A and the destination client 103B, client 103A initiates node to central server 101 and inserts request; Central server 101 is according to the close principle of IP, select a plurality of IP to provide the data relay service for client 103A near the node of client 103A or 103B, be a SN_key of each node Random assignment (node key), and a pair of client signature that utilizes the node signature to generate, promptly insert client signature and destination client signature, insert request-reply to client 103A return node then, node inserts in the request-reply and has comprised the node signature, node IP and port, SN_key and utilize the client signature of the client 103A that node signature generates and the client of client 103B to sign.
Among the step S103, client 103A sends to client 103B by the communication port that instantaneous communication system provides with node link informations such as node signature, node IP and port, SN_key and destination client signatures.
Among the step S104, after client 103B receives the node link information of client 103A transmission, each node in the node link information is carried out ping instruction, and the ping commanded response information of each node 102 is returned to client 103A.
Among the step S105, client 103A is according to the ping commanded response information of client 103B and the ping commanded response information that self each node execution ping instruction back is obtained, the node of data relay transmission is carried out in selection, and with the node notice client 103B that selects.
Among the step S106, client 103A and 103B initiate to insert request to node 102 respectively, node 102 is verified client according to the client signature of client 103A and 103B, whether the identity of judging client is legal, and whether the term of validity of signature is effective, if client identity is legal, and signature effectively, then node 102 is respectively client 103A and 103B open communication port, sets up the transfer communication passage.
Among the step S107, client 103A utilizes the SN_key corresponding with node 102 to encrypt to need the data of transmitting, and data encrypted is sent to node 102; After node 102 receives the data of client 103A transmission, whether legal by client signature judgment data, will verify that then legal data forwarding is to client 103B; Client 103B utilizes the SN_key of node 102 that data are decrypted processing after receiving the data of node 102 forwardings.
Provide in the process of data relay service for client 103A and 103B at node 102, central server 101 requires node 102 regularly to report local network traffic information, central server 101 is controlled the instant messaging quality when guaranteeing himself as client according to the network traffic information that node 102 reports in real time to maximum number of connections, initiator's request timed out value, passage maximum data packet amount and the passage maximum stream flow etc. of node 102.Node 102 is controlled local network traffics, and network traffics is controlled the result return central server 101 according to the network control message of central server 101.
Carry out in the instant messaging process between client 103A, 103B, if unsettled situation appears in the communication of node 102, as cutting off the power supply, go offline etc., client 103A, 103B can automatically switch to other node and communicate.
