摘要： A method and apparatus are provided for emulating VPLS within an ATM network. Provider Edge devices are configured for the VPLS connections. Each provider edge device advertises its configured VPLS IDs to other provider edge devices by propagating an information group up the PNNI hierarchy, the information group containing an association between an ATM address of the provider edge device and the VPLS ID. Information groups are propagated back down the PNNI hierarchy, so that each lowest level node learns all ATM addresses to be associated with each VPLS ID. For each pair of provider edge devices supporting the same VPLS ID, one of the provider edge devices establishes a virtual circuit between the pair. In this way, a mesh of virtual circuits is established between provider edge devices, and a VPLS-like service can be offered to users without having to implement MPLS. The method of advertising ATM addresses can also be applied to other services requiring a number of interconnections between provider edge devices, such as Virtual Private Networks.

摘要： A method and apparatus for emulating VPLS within an ATM network. Provider Edge devices are configured for VPLS connections. For each pair of provider edge devices supporting the same VPLS ID, one device establishes a virtual circuit between the pair. Thus, a full mesh of virtual circuits is established between provider edge devices, and a VPLS-like service can be offered to users without having to implement MPLS. Establishing the virtual circuits within a PNNI hierarchy maybe facilitated by each provider edge device propagating through the hierarchy an information group containing an association between the ATM address of the device and a VPLS ID, so that each provider edge device learns all ATM addresses to be associated with each VPLS ID. The method of advertising ATM addresses can be applied to other services requiring a number of interconnections between provider edge devices, such as Virtual Private Networks.

摘要： The present invention provides a method for permitting fully detailed advertising of reachability information for some addresses in a network while efficiently summarizing reachability information for other addresses. At least one embodiment is implemented as part of a process used by logical nodes for advertising reachability information for members of a group of nodes represented by the logical node. At least one embodiment provides an “exception” instruction that allows detailed reachable address information to be advertised for an address that would otherwise be included in summary address information. At least one embodiment allows detailed reachability information to be advertised for the particular address while still allowing summarization of reachable address information for addresses sharing a common prefix with the “exception” address. At least one embodiment thereby allows detailed information to be advertised where needed while allowing summary address information to be advertised where such detailed information is not needed.

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.
摘要翻译：一种用于在通信交换机的突发过载和持续超载期间处理呼叫信令消息的方法和装置包括通过接收多个呼叫信令消息开始的处理，其可以是呼叫建立消息，连接消息，呼叫进程消息，呼叫释放消息，发布完整消息和/或链路层信息。然后通过将呼叫处理队列的队列占用水平与第一队列占用阈值进行比较来继续处理。如果队列占用水平与第一队列占用阈值不利地进行比较（例如，队列正在存储比期望的更多的消息），呼叫信令消息基于呼叫信令消息的类型被排队到呼叫处理队列中。例如，可分发呼叫信令消息以LIFO方式入队，而不可缺少的和基本的消息以FIFO方式入队。可分散的消息是那些如果丢弃的消息对通信交换机的效率的影响最小，或者不引起超时过程来释放已经分配给特定通信建立请求的任何通信资源。

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： 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.
