Title: DATA NETWORK ADDRESS SHARING
Abstract:
A connection (5) to a first network (3, 13) is connected by way of a first routing processor (4) to a switching processor (14), which has a connection (35) to a network address translation processor (17) providing access to one or more hosted functions (22). Connections (6, 25) separate from the network address translation processor (17) are made to one or more hosted functions (9, 16, 23), incompatible with the NAT process, and also to a second network (2). This allows connections not requiring NAT to avoid the delays incurred by that process. Data packets are routed to the network address translation processor (17) or the first routing processor (4) in accordance with header information in the packet identifying a transmission control processor (17) and the second interface (35).
