Description

一种高速业务跨网通信建立方法和系统 A high-speed traffic across the network communication system and method for establishing

技术领域 FIELD

本发明涉及一种数据网络通信技术,尤其涉及一种高速业务跨网通信建立方法和系统。 The present invention relates to a data network communication technology, and particularly relates to a high-speed traffic across the network communication to establish methods and systems.

背景技术 Background technique

现有的高速业务跨网通信,比如即时消息(IM)软件的跨网数据传送,包括两种方式。 Existing high-speed inter-network communication traffic, such as inter-network data transfer instant messaging (IM) software, including two ways.

一种是直连方式,这种方式由于出口瓶颈限制,速度非常慢。 One is the direct approach, which as export bottlenecks, speed is very slow. 另一种是单^^的服务器中转方式,具体传送形式如图l所示。 Another embodiment is a single ^^ relay server, the specific transmission forms as shown in Figure l. 由于服务器只能和一方在一个网里,当客户端A通过中转服务器C中转数据给客户端B 时,客户端A与中转服务器C在一个网里,数据传送速度比较快。 Since the server and only one in a net, when the client A through C relay server relay the data to the client B, client A and C in the transit server in a network, the data transfer speed is faster. 但是,中转服务器C与客户端B之间跨网通信,所以数据传iMii度非常慢。 However, cross-network communication between the client C and the relay server B, so the data transfer iMii much too slow. 因此,客户端A到B之间传送数据还是比较慢。 Thus, between the client A to B is relatively slow data transmission.

中国宽带运营商分为电信、网通、长城宽带等等。 Chinese broadband operators into Telecom, China Netcom, Great Wall Broadband, and so on. 目前,大部分QQ用户不是在电信骨千网内就是在网通骨千网内,电信用户约占61%,网通用户约占26%。 At present, the majority of QQ users not in the telecommunications backbone network is the backbone network in China Netcom, Telecom users account for about 61%, Netcom users accounting for about 26%. 由于各网之间的出口带宽有限造成互通时数据传送非常慢,严重影响了IM跨网进行视频语音等数据业务应用的质量。 Due to limited export bandwidth between the network interworking caused when data transfer is very slow, seriously affecting the cross-network IM voice quality video and other data services applications.

具体实施方式 Detailed ways

图2是按照本发明的一个实施方案建立双机中转高速业务通信时的指令流向图。 FIG 2 is a dual-transfer instruction to establish a high speed communication service flow according to an embodiment of FIG embodiment of the present invention. 在该图中,RDS是重定向中心服务器,中转服务器1和2分别位于两个不同的运营网里,两服务器用专线互联,客户端A和B是用IM进行数据传送的两个客户端。 In the figure, the RDS redirect the central server, the relay server 1 and 2 are located in two different network operators, private line connection with two servers, client A and client B are the two data transfer with IM.

如图2所示,在步骤Tl,客户端A向RDS申请进行数据传送。 As shown in FIG. 2, in step Tl, the client A data transfer request to the RDS.

由客户端A发起,A向RDS发送请求,表示自己需要用双中转传输数据, Initiated by the client A, A sends a request to the RDS, he said he needs to double the data relay transmission,

请求包中包括对方B的IP地址。 Request packet includes the IP address B of the other. RDS根据客户端A和B的IP地址来判断它们是否处于不同的因特网服务提供商(ISP)的网络中。 The RDS IP address of the client terminals A and B to determine whether they are in a different Internet Service Provider (ISP) network. 如果判断出客户端A 和B在不同ISP网络中,RDS再根据服务器群的负载情况将空闲的中转服务器1及中转服务器2的IP地址同时传送给客户端A,同时派发相应的安全认证签名。 If it is determined that the client terminals A and B at different ISP network, RDS again according to the load server farm will transit server idle 1 and the relay server 2 IP address simultaneously transmitted to the client A, while distributing the appropriate security authentication signature.

在步骤T2,客户端A连接上与自己同一侧的中转服务器1。 In step T2, the client A is connected with its own server on the same side of a relay. 客户端A根据RDS返回的中转服务器1的IP地址,向中转服务器1发出连接建立请求,该请求中包含中转服务器2的H>地址和签名等信息。 A relay server according to the client IP address returned an RDS, issue the connection establishment request to the relay server 1, the request contains H> address and information transfer signature server 2. 中转服务器1根据收到的请求中包含的签名,验证客户端A的合法性,如果验证通过, 则同意建立中转连接。 The relay server 1 according to the signature included in the received request, verify the legitimacy of the client A, if verified, agreed to establish a transit connection. 连接建立起来之后,中转服务器1根据从客户端A收到的连接建立请求中包含的中转服务器2的IP地址来分配与中转服务器2之间一个可用的专线会话通道连接,并将标识该会话通道连接的中转房间号返回给客户端A。 After the connection is established, the relay server 1 to establish the IP address of the relay server 2 included in the request according to the connection from the client A receives the relay server to allocate an available line between two connection session channel, and identifies the channel session transit room number of the connection back to the client A.

在步骤T3,客户端A将中转服务器2的IP地址、签名及中转房间号传送给客户端B。 In step T3, the client A to the IP address of the relay server 2, the signature transfer and room number to the client B.

在步骤T4,客户端B根据中转服务器2的IP地址,向中转服务器2发出连接建立请求,该请求中包含中转房间号和签名等信息。 In step T4, the client B according to the IP address of the relay server 2, issues a connection establishment request to the relay server 2, the request contains the relay room number and signature information. 中转服务器2根据收到的请求中包含的签名进行安全认证。 2 relay server for secure authentication according to the signature requests received included. 如果认证成功,则同意建立中转连接。 If authentication is successful, then agreed to establish a transit connection. 连接建立起来之后,中转服务器2根据从客户端B收到的连接建立请求中包含的中转房间号来识别中转服务器1所分配的专线会话通道连接,并与中转服务器1之间建立这个专线会话通道连接。 After the connection is established, the relay server 2 in accordance with the room number relay received from the client B is included in the connection establishment request to identify the transit server an assigned session channel connecting line, and the establishment of the session path between the line and the relay server 1 connection.

在步骤T5,客户端A与B通过中转服务器1和2双服务器互传数据。 In step T5, transfer data to the client A and B through the relay server 1 and the two pairs of servers. 第一网络内的中转服务器1,比如电信机房内的某台中转服务器,收到客户端A发送来的数据时,先通过专线传送给第二网络内中转服务器2,比如网通的服务器,然后中转服务器2再将该数据传送给客户端B。 When the relay server in the first network 1, such as a transfer station in the telecommunications room server, client A receives the data transmitted, through the first line is transmitted to the second transit network server 2, such as the company's servers, and then transfer the server 2 then transmits the data to the client B.
