COOPERATIVE PROXY AUTO-DISCOVERY AND CONNECTION INTERCEPTION |
摘要 |
In a network supporting transactions between clients and servers and proxies that are interposable in a network path, a pair of proxies can modify a packet stream such that packet data from client to server is transformed at a client-side proxy of the pair and untransformed at a server-side of the pair and packet data from server to client is transformed at the server-side proxy and untransformed at the client-side proxy. A discovering proxy transparently discovers its position in a proxy pair by using proxy signals. A discovering proxy might determine that it is a client-side proxy by receipt of a packet from client without a proxy signal, or that it is a server-side proxy by receipt of a packet from server without a return proxy signal. Once a proxy pair is discovered, it might transform traffic from server to client or vice versa, transforming and untransforming the traffic. |

1. A method of probing for devices on a network path, the method comprising:
monitoring, at a first probe node in the network path, packets directed at a target client and apparently from a target server to detect packets containing return signals, wherein the return signal is an indication that the device at a second probe node has detected a previously sent presence signal as being a probing signal; upon determining that a return signal is responsive to a previously sent presence signal, storing information associated with the second probe node at the first probe node; and using the stored information in future communications between the target client and the target server.
