摘要： An improved client network address translation (“NAT”) system is provided. Methods are provided for initializing connection control blocks with the client NAT addresses when a storage pool of connection control blocks are allocated. This avoids the costly overhead as connections are created and destroyed. Unlike the prior art solutions, once the connection control blocks of the present invention are allocated, they remain in effect until the storage subpool is deleted. Secondly, in order to provide as large a pool of client NAT addresses as possible, methods are provided for using intervals to allocate and reclaim client NAT addresses as subpools are allocated and freed.

摘要： Mechanisms and techniques provide a method for routing a packet that includes a content request and an Internet Protocol address and port number that identify a source transmitting the packet. The method relates to selecting a routing policy to forward the packet, based upon at least a portion of content request. The method includes a data communications device receiving a packet having a content request and an Internet Protocol address and port number that identify a source transmitting the packet. The device performs a network address translation, based upon at least a portion of the content request, to translate the Internet Protocol address and port number of the packet to a respective communications device Internet Protocol address and communications device port number. The device then selects a routing policy based upon the communications device Internet Protocol address and routes the packet to a destination according to the routing policy.
摘要翻译：机制和技术提供了一种用于路由分组的方法，该分组包括内容请求和识别发送分组的源的因特网协议地址和端口号。该方法涉及基于内容请求的至少一部分来选择转发分组的路由策略。该方法包括接收具有内容请求的分组的数据通信设备和识别发送分组的源的因特网协议地址和端口号。设备基于内容请求的至少一部分执行网络地址转换，以将该分组的因特网协议地址和端口号转换为相应的通信设备因特网协议地址和通信设备端口号。然后，设备基于通信设备因特网协议地址选择路由策略，并根据路由策略将分组路由到目的地。
