摘要： Proxy devices associate their direct connection with a client/server connection passing through one or more NAT devices. First proxy device receives a network connection request from a client. First proxy device stores connection information in association with a connection identifier. Connection information may reflect the usage of NAT devices between the two proxy devices. First proxy device sends a connection response including the connection identifier to the client. Second proxy device sends a direct connection request to first proxy device to establish a direct connection. Direct connection request includes the connection identifier, which is used by first proxy device to associate the direct connection with stored connection information. First proxy device may use the connection information to direct network traffic received via this direct connection to the correct destination and to divert network traffic from the server to the client through the direct connection and first and second proxy devices.

摘要： In a network supporting transactions between clients and servers and proxies that are interposable in a network path between at least one client and at least one server, wherein a pair of proxies can modify a packet stream between a client and a server such that packet data from the client to the server is transformed at a client-side proxy of the proxy pair and untransformed at a server-side proxy of proxy pair and such that packet data from the server to the client is transformed at the server-side proxy and untransformed at the client-side proxy, a method and apparatus for a discovering proxy to transparently discover its position in a proxy pair by using proxy signals to indicate to other proxies that could pair with the discovering proxy. A discovering proxy might determine that it is a client-side proxy by receipt of a packet from client without a proxy signal. A discovering proxy might determine 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, that proxy pair might transform traffic from the server to the client or vice versa, transforming the traffic at one proxy of the proxy pair and untransforming the traffic at the other proxy of the pair.

摘要： Self-discovering transaction accelerators improve communications between a client and a server. A client directs a message to a server. A client-side transaction accelerator intercepts the message, terminates the connection with the client, and accelerates the request by replacing segments of data with references. The accelerated request is forwarded to a server-side transaction accelerator through a new connection. The server-side transaction accelerator reconstructs the message by replacing the reference with segment data in a persistent segment store accessible to the server-side transaction accelerator. The reconstructed request is then provided to the server. Accelerations may occur in any direction of communication. Persistent segment stores can be pre-populated with segment data from other transaction accelerators and anticipated transactions. The persistent segment store can store segments that are data segmented based on content of the data and can be independent of transaction protocol, application, and device.
摘要翻译：自发发现事务加速器可改善客户端与服务器之间的通信。客户端将消息指向服务器。客户端事务加速器拦截消息，终止与客户端的连接，并通过用引用替换数据段来加速请求。加速请求通过新连接转发到服务器端事务加速器。服务器端事务加速器通过将服务器端事务加速器可访问的持久段存储中的段数据替换为引用数据来重构消息。然后将重建的请求提供给服务器。加速可能发生在任何通信方向。可以使用来自其他事务加速器和预期事务的段数据预先填充持久性段存储。持久段存储可以存储基于数据内容进行数据分段的段，并且可以独立于事务协议，应用和设备。
