摘要： In source routed or hop-by-hop routed protocol communication networks, when congestion is detected at a certain network element, a notification message is sent to nodes. The nodes keep track of congestion condition and generally have knowledge of the congestion, thereby allowing them to make more intelligent routing decisions, i.e., rate controlling messages, routing traffic around congestion, regulating admission at the edge of the network. The intelligent routing decision is based on the congestion condition indicated by a restriction level which is periodically and dynamically updated.

摘要： A method and apparatus for processing call signaling messages during burst overloading and sustained overloading of a communications switch include processing that begins by receiving a plurality of call signaling messages, which may be call set-up messages, connect messages, call proceeding messages, call release messages, release complete messages, and/or link layer information. The processing then continues by comparing a queue occupancy level of a call processing queue with a first queue occupancy threshold. If the queue occupancy level compares unfavorably with the first queue occupancy threshold (e.g., the queue is storing more messages than desired), call signaling messages are enqueued into the call processing queue based on the types of the call signaling messages. For example, dispensable call signaling messages are enqueued in a LIFO manner while indispensable and essential messages are enqueued in a FIFO manner. Dispensable messages are those, that if dropped, have minimal impact on the efficiency of the communication switch and/or do not evoke a time-out process to release whatever communication resources have been allocated to a particular communication set-up request.

摘要： Systems and methods of monitoring a communication traffic transfer rate control mechanism are provided. The traffic transfer rate control mechanism may control a rate of transfer of communication traffic from a first communication traffic management device to a second communication traffic management device, for example. A communication traffic storage history, which is indicative of an effect of the transfer rate control mechanism, is compiled by determining amounts of communication traffic stored in at least one communication traffic queue of at least one of the communication traffic management devices, at each of a number of monitor times. An indication of the determined amounts of communication traffic is provided, and may be analyzed to determine whether the transfer rate control mechanism actually achieves a desired effect. The transfer rate control mechanism or control parameters thereof may then be adjusted if the desired effect is not currently being achieved.

摘要： The present invention provides a system and method of calculating a service disruption in a communication network comprising network elements, including nodes connected via links and at least one originating node. Each node is able to detect a failure in an adjacent network element. Upon detection of a failure, a first timestamp is generated. The detecting node generates a release signal which is transmitted, together with the first timestamp, to an originating node which releases the affected connection. The originating node establishes a new connection and initiates a new call. Upon establishing a new connection, a node affected by the failure, which forms a part of the new connection, records a second timestamp. The second timestamp is chosen to reflect, as closely as possible, the actual time of restoration of service in the network. Service disruption is measured as a difference between the first and second timestamps.

摘要： The invention provides a system and method of a selecting an egress connection from egress connections at a node for a call being established in a network along a path being associated with the node. Each connection has sufficient bandwidth to carry the call and terminates at a same destination point in said path. The system and method comprise utilizing at least a bandwidth load balance value for each connection in a set of the connections to select the egress connection from the set. An administrative factor score may be used to further define members of the set.

摘要： In a message delivery system, wherein messages are published by publishers and delivered to subscribers based on subscriptions relating to message content. A last message queue is associated with each publisher, and a last message from each publisher is stored in the message queue associated with that publisher based on an attribute of the publisher. In this way, it is not necessary to modify the content data within the message to create the last message queue.

摘要： A method of providing a shared application infrastructure simultaneously to multiple independent virtual private networks with potentially overlapping IP addresses, involves connecting to an underlying layer 1, 2 or 3 virtual private network offering one or more virtual private networks, determining which virtual private network traffic is being received from or sent into, maintaining logically separate routing tables per VPN to allow overlapping addresses, and providing an application which provides a logical instance of the service to each VPN.

摘要： In a method of managing a content-based network, which is typically XML-based, and optionally may be overlaid on an underlying network having a plurality of network elements interconnected by links, a link state protocol maintains each network element's topological view of the overlay network from the underlying network. A subscription management protocol ensures dissemination of published content within the content-based network independently of the link state protocol.
