摘要： A method and apparatus for rerouting connections in a data communication network based on detection of faults or other undesirable characteristics using a user connection monitoring function is presented. After a connection is established that is managed by a control plane, the status of characteristics of the connection is monitored using a user connection monitoring function. In one embodiment, the user connection monitoring function includes the use of operation and management (OAM) cells. When the status of one or more of the selected characteristics being monitored is determined to be unacceptable, control plane rerouting of the connection is initiated. Selected characteristics that may be monitored using the user connection monitoring function include, for example, continuity, data corruption, data loss, latency, and misinsertion of data. The reroute initiated in response to the unacceptable characteristic may be a hard reroute or a soft reroute.

摘要： An event processing system performs quickly processing of events in a communication network. The system comprises a client process that controls the sequencing of event processing, a plurality of servers that process the events with the help of a shared object library and a dispatcher that selects an available server so that no two servers process events from the same event queue at any given time. The client time-stamps the events and organizes them into event queues per node, using a node identification. An outstanding queue tracks the current events being processed for a node based on a message ID that is returned by the dispatcher when an event is sent to a server. Also, an overflow queue tracks the sequence of nodes to be serviced after a maximum outstanding limit of events being processed at a given time has been reached.

摘要： A method and apparatus for communicating data packets according to classes of service is described. One or more service interfaces are coupled to a plurality of transport interfaces. The service interfaces carry packets having multiple classes of service, while each of the plurality of transport interfaces carries packets of a single class of service. A differentiated services codepoint profile is associated with each service interface and maps a differentiated services codepoint value of a data packet to a class of service and a drop precedence. The data packet is assigned to a transport interface based on its class of service and its drop precedence. Other factors, such as the destination of the data packet may be considered when assigning the data packet to a transport interface. Data packets from different transport interfaces are preferably enqueued in different queues of a destination service interface.

摘要： A method and apparatus for communicating and utilizing control plane congestion information in a communication network that utilizes a source routed signaling protocol is presented. When control plane congestion is detected at a network element within the communication network, a congestion notification message is generated corresponding to the detected control plane congestion. The congestion notification is then provided to at least one additional network element within the communications network. The at least one additional network element can then utilize this knowledge of the congestion within the network to perform various network functions, including the routing a connection set-up message.

摘要： A method and apparatus for optimizing redundant link usage allows a portion of the wasted bandwidth in a redundant link system to be utilized for additional data traffic without compromising the ability of the system to respond to and correct for a failure of a link. In one embodiment, one of two independent, individually addressable links is selected as a nominal communication path, and the other as a standby communication path. The path independent traffic is sent via the nominal communication path, while the path dependent data is sent via the nominal communication path or the standby path, in accordance with the dependence of the traffic. In another embodiment, critical time sensitive traffic is sent via a nominal and standby time sensitive paths, while normal traffic is sent via nominal normal path, and non-critical traffic is sent via a standby normal path.

摘要： An interface system and method for creation and configuration of a connection between routers is provided. The interface comprises facility for entry of physical connection information, and entry of protocols selection and configuration information. Information for selection and configuring routing instances, network interfaces, and protocols for the connection is only requested from the user interface once before it is forwarded to an NMS to carry out the steps for actually setting-up the connection. Transport and protocol profiles for re-use with various physical connections are also provided.

摘要： A method and apparatus for controlling multicast group subscriptions in a multicast distribution circuit is presented. When a router included in the multicast circuit receives notification to terminate support of a particular multicast group (group leave request), data flow with respect to that multicast group is initially maintained on the communication link coupling the router to the hosts. Queries are issued to hosts on the communication link to determine whether continued support of the particular group is desired by any hosts coupled to the communication link. If, while waiting for a positive response to the queries issued, a request to join an additional multicast group is received, bandwidth availability on the communication link is examined to determine if adequate bandwidth is available for supporting the newly requested group addition. If adequate bandwidth is available, the newly requested group is added to those groups supported on the communication link. However, if adequate bandwidth for support of the newly requested group is not available, one or more groups that are pending termination (group specific queries have been issued for these groups) are selected for early termination in order to make enough bandwidth available to support the newly requested group addition. The selection criteria utilized to determine the groups to be terminated may be based on a variety of parameters.

摘要： An embodiment of the present invention provides a method for network management that allows the configuration of IP links in one step, via a GUI form, even though the management protocols available at the two end links (routers) may differ. According to one embodiment, the method comprises gathering information from the user, validating this information, and then sending this information to the appropriate router(s). According to one embodiment, the method enables a user to specify various configurations when provisioning an IP link, for example, the type of IP link (Point-to-Point, Point-to-IP, or Point-to-Subnet), the numbering type (Numbered or Unnumbered), the application type (MPLS and/or IP Forwarding), and the sub-layer interfaces to be used (Packet Over Sonet, Asynchronous Transfer Mode, GigEthernet, and others). In addition, according to one embodiment, the method allows the IP link to be associated to existing router interface(s), or the interfaces can be created as part of the IP link creation process.

摘要： A method for distributing aggregate routes that does not require a user to provision a next hop address or specify a redistribution policy is presented. Embodiments of the method utilize a modified command language interface (CLI) with a network device (e.g., router). In the various embodiments, the modified CLI is well-suited for use in routers that utilize interior gateway protocols such as open shortest path first (OSPF), routing information protocol (RIP), integrated intermediate system-to-intermediate system (ISIS), interior gateway routing protocol (IGRP), enhanced interior gateway routing protocol (EIGRP), and NetWare link services protocol (NLSP). In one or more embodiments, the invention has the advantage of providing an easier means of specifying aggregate routes, which saves user time and is less error-prone.
