摘要： There is provided a method and apparatus for the prioritization, multiple queuing and selective processing of PVC management frames by a Frame Relay message processing device. The device had an input port for receiving the messages. It also provides a number of message queues for storing and retrieving the received messages, each of the queues respectively corresponding to one of a number of response priority levels which vary from highest priority to lowest priority. Each of the response priority levels is assigned to a number of message classes associated with predetermined link management processes for communicating the status of message relay links among networking devices. The message processing device has a first processor for determining the message class associated with each of the received messages and for allocating each of the messages to a corresponding one of the queues based upon the response priority level assigned to the determined message class. A second processor is provided for retrieving each of the messages from the queues, and an output port is provided for dispatching the retrieved messages.

摘要： Embodiments of the invention are directed to monitoring resources of a network processor to detect a condition of exhaustion in one or more of the resources over a predetermined time interval and to provide an indication of the condition. Some embodiments periodically sample various resources of a network processor and from the samples calculate utilization of the network processor's memory bus and core processor, and determine if an interworking FIFO packet queue error has occurred. Such information may help network operators and/or support engineers to quickly zero in on the root cause and take corrective actions for network failures which previously could have been attributed to many different causes and that would have required significant time and effort to troubleshoot.

摘要翻译：本发明的实施例涉及监视网络处理器的资源，以在预定时间间隔内检测资源中的一个或多个资源中的耗尽状况，并提供该状况的指示。一些实施例周期性地对网络处理器的各种资源进行采样，并且从样本中计算网络处理器的存储器总线和核心处理器的利用率，并且确定是否发生了互通的FIFO分组队列错误。这些信息可能有助于网络运营商和/或支持工程师迅速消除根本原因，并对以前可能归因于许多不同原因的网络故障采取纠正措施，并且需要大量时间和精力进行故障排除。
