摘要： The method and apparatus of the present invention may be utilized to interconnect multiple local area networks to a data processing network including both multiple network nodes having routing and functional capability within the data processing network and multiple endpoint nodes having only local address capability, while minimizing the amount of routing information which must be maintained within the data processing network. A concentrator node is established for interconnection between each of the multiple local area networks and the data processing network. The concentrator node includes a network node interface having routing and functional capability for an associated local area network and an endpoint node interface having local address capability. When interconnected between a local area network and a selected network node within the data processing network, the concentrator node emulates a network node within the local area network while appearing as an endpoint node within the data processing network. The concentrator node maintains routing information for communication between the local area network and the data processing network in two segments. The first segment details the route between the local area network and the concentrator node while a second segment details the route between the concentrator node and a node within the data processing network.

摘要： An Adaptive universal multiple access (AUMA) apparatus and method for collision-free, high efficiency multiple access to a shared media uses a corrector to control access to ports in a hub. The corrector assigns each node an active or passive state and subdivides each transmission cycle into NA sub-cycles, where NA is the number of active nodes in the network. The corrector is configured so that each active node is accessed during one sub-cycle. AUMA may be implemented in repeaters, head-ends, or network interface cards in wired, or wireless networks. To provide efficient utilization AUMA has several mechanisms of automatic adaptation to network topology, lengths of media, node activity, bursty traffic, and speed of transmission. AUMA is compatible with standard Ethernet and can be used in Ethernet environment, including mixed networks, where some nodes are UMA nodes, and the other are standard Ethernet nodes.

摘要： The invention relates to the implementation of an access service in a telecommunications network comprising an access network, a network providing services, and user-operated terminals which are connected to the access network. The access service is offered by connecting the user terminal to the network providing the services through interface elements which connect the access network and the network providing the services. As a response to the access service at least one charging record is generated. The record is transferred to billing means for billing the access service subscriber for the access service. So that it would be possible to combine the access service with reliable and versatile billing in a connectionless network, the terminal is used to generate charging messages which are provided with a subscriber-specific digital signature, and the signatures generated by the terminal are verified outside of the terminal. The terminal is given access to the network providing the services, if said messages are received in an acceptable manner. The terminal sends the network data about the subscriber associated with the current user of the terminal, whereby said data are used to verify the validity of the signatures and to target the charging messages received from the terminal at the billing of the subscriber in question.

摘要： A route finder for point to multi-point connection requests in a communications network comprising a plurality of nodes connected by a plurality of links. A cost is assigned to each network link. For each connection request a set of all network nodes not included in its source node or its plurality of destination nodes are selected. An array of bits is created with an array element corresponding to a selected node element having a value of 1 if the node is steiner vertex for a steiner tree of nodes not selected, otherwise the array element has a value of 0. Each array is treated as a bit string and considered as population members which are manipulated by genetic algorithms. The fitness of the population members is evaluated by calculating the cost of traversing the routes represented by the bit strings. The method is capable of routing a plurality of multi-point connection requests, and selecting an overall optimum solution.

摘要： Efficient topology aggregation is realized by generating a full-mesh topology from an original sub-network topology, without compromising accuracy. Then, the full-mesh topology is reduced to a first spanning tree aggregation topology. Distortion in the first spanning tree aggregation topology is evaluated to determine if the resultant spanning tree aggregation topology requires further refinement in order to meet a predetermined distortion criterion. If no further refinement is required, the aggregation topology is advertised. Additionally, a network parameter, e.g., a so-called network radius is generated from the full-mesh topology. In this example, the network parameter is evaluated along with the first spanning tree aggregation topology to determine if the spanning tree aggregation topology requires further refinement. If no further refinement is required, both the aggregation topology and the network parameter are advertised.

摘要： A method for detecting a routing loop when repairing a bidirectional multicast distribution tree is disclosed. According to the method, a splice message is launched from an originating node attempting to join a bidirectional multicast tree and is sent to a root-node to find out if a routing loop is formed when a node is joining the multicast distribution tree. Depending on the multicast application requirement, when a routing loop is detected during the repairing of a multicast distribution tree, the severed node may abort, or the repair can be deferred until the connection to the root-node is re-established. The loop detection and loop prevention method of the invention may be used as a loop avoidance mechanism with any protocol for repairing a partitioned tree.

摘要： A method for establishing a network connection through a link issuing from a physical port is disclosed. The link has an aggregation of connections. The network connection has a required capacity. The method first computes, from mean bit rates of the aggregation of connections, a mean aggregate bit rate over the aggregation of connections. The method secondly computes, from burst durations from the aggregation of connections, a mean aggregate burst duration over the aggregation of connections. The method thirdly computes an equivalent capacity required on the link by the aggregation of connections, the equivalent capacity being a function of the mean aggregate bit rate and the mean aggregate burst duration. The method fourthly computes an aggregate equivalent capacity, the aggregate equivalent capacity being a function of the equivalent capacity and the required capacity of the connection. The method fifthly computes a bandwidth that would be reserved on the link after establishing the connection, the bandwidth being a minimum of a Gaussian approximation and the aggregate equivalent capacity. Then the network connection is established if the bandwidth is less than or equal to a total capacity for the link.
