摘要： A system is provided for selecting connection paths in a telecommunications network having a multiplicity of nodes interconnected by a multiplicity of links. The system identifies multiple constraints for connection paths through the network between source and destination nodes, and identifies paths that satisfy all of the constraints for a connection path between a selected source node and a selected destination node. A system is also provided for optimizing utilization of the resources of such a telecommunications network by establishing connection paths through the network between selected source and destination nodes, the established connection paths satisfying the constraints; for each established connection path, determining whether other connection paths exist between the selected source and destination nodes, and that satisfy the constraints; and if at least one such other connection path exists, determining whether any such other connection path is more efficient than the established connection path and, if the answer is affirmative, switching the connection from the established connection path to the most efficient other connection path.

摘要： A telecommunications system includes a network for transporting packets on a path between selected subscriber end points. The network has multiple nodes connected by links, with each node (a) pairing the forward and backward paths of a connection and (b) allowing for the injection of messages in the backward direction of a connection from any node in the path without needing to consult a higher OSI layer. A system is also provided for protecting connection paths for transporting data packets through an Ethernet telecommunications network having a multiplicity of nodes interconnected by a multiplicity of links. Primary and backup paths are provided through the network for each of multiple connections, with each path including multiple links. Data packets arriving at a first node common to the primary and backup paths are duplicated, and one of the duplicate packets is transported over the primary path, the other duplicate packet is transported over the backup path, and the duplicate packets are recombined at a second node common to the primary and backup paths.

摘要： A system is provided for controlling the flow of data-packet traffic through an Ethernet telecommunications network having a multiplicity of nodes interconnected by multiple network links. Incoming data-packet traffic from multiple customer connections are received at a first node for entry into the network via the first node. Flow control messages are generated to represent the states of the first node and, optionally, one or more network nodes upstream from the first node, and these states are used as factors in controlling the rate at which the incoming packets are admitted to the network. Alternatively, the flow control messages may be used to control the rate at which packets generated by a client application are transmitted to the first node.

摘要： A method of controlling the flow of data packet traffic from a first point to at least two second point in an Ethernet telecommunications network having a multiplicity of nodes interconnected by multiple network links, comprises monitoring the level of utilization of a link between the first and second points, generating flow control messages representing the level of utilization and transmitting the control messages to the first point, and using the states represented in the flow control messages as factors in controlling the rate at which the packets are transmitted from the first point to the second point. A method of controlling the flow of data packet traffic through an Ethernet telecommunications network having a multiplicity of nodes interconnected by multiple network links, comprises receiving incoming data packet traffic from multiple customer connections at a first node for entry into the network via the first node, the first node having an ingress trunk, and limiting the rate at which the incoming data packets are admitted to the network via the ingress trunk.
