A system and method provides network address translation as an external service for private networks. Give the fact that local office networks (i. e. , stub networks) are typically assigned only one globally unique IP address (or a small set of addresses), the invention presents a novel service provider access server (e. g. , router) which performs basic network address translation (NAT) and network address port translation (NAPT) for such networks. The system allows NAT and NAPT features to be removed from stub network routers, thereby significantly reducing the cost of Internet infrastructure to individual companies and organizations. NAT features on service provider's access servers provide the ability for multiple hosts in disparate private (unregistered) networks to utilize the services of a service provider, using a single global address for each private network and allow private networks to avoid renumbering with access to each new service provider.

A communication technique for high volume connectionless-protocol, backbone communication links in distributed processing systems provides for control of latency and reliability of messages transmitted. The system provides for transmit list and receive list processes in the processors on the link. On the transmit side, a high priority command list and a normal priority command list are provided. In the message passing process, the command transmit function transmits commands across the backplane according to a queue priority rule that allows for control of transmit latency. Messages that require low latency are written into the high priority transmit list, while a majority of messages are written into the high throughput or normal priority transmit list. A receive filtering process in the receiving processor includes dispatch logic which dispatches messages either to a high priority receive list or a normal priority receive list. The filtering function also acts to drop messages received according to the amount of available buffer space in the receiving processor, as measured against watermarks based on reliability tags in message headers.
