Abstract
The invention relates to the network communication forwarding technology, and provides a communication implementation method based on an application-layer transparent proxy technology. The communication implementation method comprises the following steps: proxy service takes an IP (Internet Protocol) address of a client side or a server side as a source IP address to perform local binding, and sends a connection establishment request to the server side or the client side through a TCP (Transmission Control Protocol)/IP stack; and a data link layer (DLL) transfers a data response packet to a proxy directional association module for processing the data response packet and associating the processed data response packet to connection involved in the connection request sent by the proxy service so as to perform association processing and further realize communication implementation between the client side and the proxy service or between the proxy service and the server side. In the communication implementation method, under a transparent proxy technical model, a transparent proxy only needs to pay close attention to application-layer businesses which need to be provided with the proxy service (FTP (File Transfer Protocol) service), the other services can reach the server side by a two-layer network transparent forwarding mode, and the transparent proxy only processes transparent proxy forwarding of the FTP, which greatly meets the requirement for flexibility of business correlation processing and embodies independence and advancement of the transparent proxy service mode.

(3) after agency service was through above-mentioned two establishment of connections success, follow-up needs carried out the round forwarding of packet through perfect connection, can realize the miscellaneous service demand for services based on Transparent Proxy.
Among the present invention, only needs are carried out agency's business datum execution Transparent Proxy service, and other business datums are adopted the mode of two layers of forwarding of network protocol stacks.Business data packet to agency's forwarding and two layers of forwarding of network protocol stack does not change its content, directly carries out two layers of Transparent Proxy service or network protocol stacks and transmits original client and service end data bag.
The difference that the present invention and other are acted on behalf of scheme is:
1, realizes the Transparent Proxy forwarding mechanism in application layer
Transmit in the implementation in traditional network packet; It is the forwarding of pure packet; The typical case, does not act on behalf of though accomplished the transparency like the packet routing forwarding implementation of switch, router; Promptly not setting up TCP with the two ends of communication respectively and be connected, only is that the bag of network protocol stack data link layer and network layer is transmitted.
In traditional agency mechanism, no matter be that the application layer or the agency of network protocol stack bottom transmit, all can't accomplish the transparency.No matter be forward agency or reverse proxy, agency service all needs independent IP address, and TCP is connected and carry out active data bag transport communication as setting up with client and service end with this.This dual mode; Opaque for client; Opaque for service end, if, then can't accomplish seamless insertion in the basic deploy agency service of original client and service end communication construction; And the configuration that need be correlated with to client or service end, could the successful implementation agency service.
Transparent Proxy mechanism of the present invention; Then demonstrated fully the two-way transparent characteristic of client and service end; Can not only independently set up TCP and be connected, realize the transparent forwarding of packet with two ends, and in the network topology environment that original ripe client is communicated by letter with service end; Can be as increasing the network two-layer switching equipment, seamlessly must insert the Transparent Proxy service.This invention has supported to increase in the complex network environment maintainability and the scalability scheme of miscellaneous service greatly.
2, the innovation realization mechanism of uniqueness
The Transparent Proxy main frame need not possess the IP address of communicating by letter with service end with client, seems just as two layers of exchange of network forwarding unit.As everyone knows, purpose IP address is not the network communication data bag of this host IP address, can't arrive application layer through transport network layer, because this locality does not provide service TCP serve port and is connected.Reverse proxy and forward agent skill group, they need be configured into the industry IP address of communication of being engaged in, and carry out conventional TCP and connect and communicate by letter so can follow a well mapped-out plan; Equally, for the forwarding unit of two layers on network and three layers, need not set up TCP and connect, transmission network packet only need not run counter to the rule of any ICP/IP protocol stack yet.
The Transparent Proxy technology, needing to break through reception IP address is the restriction of the packet of non-main frame local ip address, and sets up virtual TCP connection and monitor serve port.When the packet of client-access arrives agency service host data link layer; The connection orientation of packet is associated with local monitoring serve port; The IP address that local monitoring serve port adopts service end at this moment is as source address; Set up TCP with client and be connected, client is connected with TCP between the agency service just to set up and finishes like this.In like manner, after agency service and client have been set up TCP and be connected, need set up TCP with service end and be connected, at this moment, agency service, is set up TCP with service end and is connected as source IP address with the original ip address of client.After two-way connection was set up and finished, client and service end just can be carried out transfer through agency service, realized the data communication that connects based on TCP.
For UDP communication send a letter here, need not set up reliable connection, therefore in the process of communications, just save the TCP establishment of connection process of foregoing description, and only used the purpose that reaches transparent transmission through the exchange of IP address.
3, a care needs agency's data service
Traditional forward agency and reverse proxy technology based on application layer, owing to disposed the IP address of direct communication, the IP address is as the direct target of communication, so it has occupied an independently communication entity.When service end provides a plurality of application service, as and HTTP is provided service, also comprise FTP; SSH service etc., then under traditional agent framework, the configuration of acting server; Not only HTTP need be supported, FTP must be supported, SSH etc.; Otherwise the service that service end provides just can't obtain normal communications access.
Transparent Proxy technology mainly is based on the shortcoming of forward agency and reverse proxy technology, carries out a kind of brand-new improvement implementation, thereby realization is to client and service end transparent way all.Under the Transparent Proxy technology, the purpose IP address of client-access is the direct IP address of service end, advances after the Transparent Proxy service, and the original visit IP address that service end is seen is the IP address of client not yet.Under a kind of like this technic relization scheme, in the network topology structure of disposing the Transparent Proxy service, need not change any network configuration, just can realize the application deployment of Transparent Proxy service.
