摘要： A wireless services data network supporting the mobility of an Internet Protocol (IP) over ATM networks is implemented such that a joint ATM-layer hand-off and MAC-layer hand-off are respectively used to handle in-session and inter-session mobility. In this way the effect of mobility is localized and transparent to higher-layer protocols. Also, different functions, including the so-called Address Resolution protocol, location of a mobile, and ATM connection, are combined to reduce front-end delay for connectionless packet transmissions in connection-oriented ATM networks.

摘要： A call signaling protocol that uses simplified messaging to set up, confirm set up, tear down, and confirm tear down of a connection. The available capacity of communications links is tracked so that it can be quickly determined whether or not a link can handle a call. Segments (e.g., time slots, wavelengths, etc.) of a link having enough available capacity are allocated by a separate operation. Connection state information is also tracked. The simple messages and information used by the signaling protocol permits it to be easily implemented in hardware. Such an implementation enables high-speed, high-capacity, call signaling.

摘要： A connectionless packet network and an optical WDM network are interconnected by one or more optical interface modules (gateways) that include both optical to electrical interfaces, as well as a connection management module, or control element, that is arranged to control the OADM's and the configuration of lasers and port assignments within the gateways, such that a route through the optical network to a desired endpoint is selected. The OADM's can be programmed, (i.e., locally or remotely controlled by the control element) such that the wavelengths that can be added or dropped by an OADM can be changed, thereby allowing routes to be established through the optical network, from an originating gateway to a destination gateway. In addition, the optical interface modules can include a plurality tunable lasers that can be controlled such that routes can be established through the optical network without requiring changes to the routing table that associates particular endpoints with particular ports. The system can be operated in a “provisioned” mode, where connections are set up a priori (i.e., before actual traffic flow starts), or in a “switched” mode, where connections are set up on a session by session (call by call) basis. The interface modules can be integrated with the components otherwise present in conventional packet routers, or housed separately in intelligent gateways that interconnect conventional packet routers with OADM's on an optical WDM network.

摘要： An address interworking system and method for an internetwork that includes a first network using first network addressing communicating via one or more internetworking gateways with a second network using second network addressing. The gateways register one or more first network addresses in the second network as first network address-encapsulated or- mapped second network addresses. Reachability information regarding the first network-encapsulated or -mapped second network addresses is then disseminated through the second network. When a communication request containing a first network destination address is received from the first network at one of the gateways, the receiving gateway performs encapsulation or mapping of the first network destination address into a first network-encapsulated or -mapped second network destination address. It then routes a communication request containing the first network-encapsulated or -mapped second network destination address through the second network based on said disseminated reachability information.

摘要： Arrangements and methods for improving the probability of finding a connection path that meets user specified delay requirements. The improvements offer packet switches enhanced path selection that will improve the resource utilization of networks, both flat networks and hierarchical networks incorporating such switches. The latter type of networks run the path selection algorithm in the PNNI v1.0 standard where the packet switches are asynchronous transfer mode switches. Two modes of enhanced delay-based path selection are based on two different accumulation methods, namely an additive method and an asymptotic method.

摘要： A facility is provided in which an ATM switch may operate as a switch in the provision of connection oriented services and operates as a router in the provision of connectionless services. In the router mode, the ATM switch may determine "on the fly" a route which may be used to forward received data cells to an intended destination and then forwards each of the data cells in sequence over the determined route. In the switch mode, the ATM switch operates conventionally and forwards a received data cell over a previously defined switched virtual path. In certain cases, the ATM switch may operate as a router only.

摘要： Disclosed is a location management method for a communication network. In a first embodiment, a procedure for finding an optimal path between a calling switch and a visiting switch node is integrated in the call set up procedure. The connection set up procedure starts by setting up a connection path between the calling switch and the home switch. Then, an “optimal crossover node” is determined along the connection path and then the connection path is cranked back starting from the home switch and moving towards the optimal crossover node. Once the optimal crossover node is reached, the a connection set-up proceeds to set up a connection between the optimal crossover node and the visiting switch. In an alternative embodiment, first a connection is set up between the calling switch and the home switch. Then the connection is extended to the visiting switch either by the call-forwarding or by two-phase crankback method. This results in a quickly routed, but sub-optimal connection. Once the connection extension is completed by call forwarding or by the two phase crankback scheme, the route is optimized by selecting a segment on the sub-optimal connection for route optimization and then utilizing the method of the first embodiment to establish an optimally routed connection.
