Abstract: Asynchronous network interface and method of synchronisation between two applications on different computers is provided. The network interface contains snooping hardware which can be programmed to contain triggering values comprising either addresses, address ranges or other data which are to be matched. These data are termed “trip wires”. Once programmed, the interface monitors the data stream, including address data, passing through the interface for addresses and data which match the trip wires which have been set. On a match, the snooping hardware can generate interrupts, increment event counters, or perform some other application-specified action. This snooping hardware is preferably based upon Content-Addressable Memory. The invention thus provides in-band synchronisation by using synchronisation primitives which are programmable by user level applications, while still delivering high bandwidth and low latency.

Abstract: A system and method for networking. A globally valid address in a Wide Area Network includes device identification information and device location information, wherein the device identification information is distinct from the device location information. This facilitates providing network services for mobile devices. Device identification information includes a persistent, globally unique identity for devices that can be coupled to the network, and for each communication endpoint adapted to be coupled to the Wide Area Network. Network addresses are portable, allowing a network services customer to easily change its network service provider, and supporting hosts that have more than one network interface. Inline agents provide network services efficiently and transparently to users. The present invention provides a definition of network service that scales well and is capable of exploiting opportunities that will be presented by new network technologies.
