摘要： Erroneous data due to faults are prevented from propagating through a distributed network node having diversely routed communications links by using a fault masking technique that eliminates the 60 ms of error propagation time associated with SONET networks. The fault masking technique can also prevent random bit errors from propagating through the distributed network node. A frame alignment technique used in the network node is scalable for very wide words (e.g., 128 bits) for use with high speed optical communications protocols, such as OC-192.
摘要翻译：通过使用消除与SONET网络相关联的60ms的错误传播时间的故障屏蔽技术，防止由故障导致的错误数据传播通过具有不同路由通信链路的分布式网络节点。故障屏蔽技术还可以防止随机位错误传播通过分布式网络节点。在网络节点中使用的帧对准技术对于用于与诸如OC-192的高速光通信协议一起使用的非常宽的字（例如，128位）是可缩放的。

摘要： A communication system includes a first ingress content processor that receives information associated with a first traffic type. The first ingress content processor places the information associated with the first traffic type into a system cell having a common system cell format. A second ingress content processor receives information associated with a second traffic type. The second ingress content processor places the information associated with the second traffic type into a system cell having the common system cell format. A switch fabric receives system cells from the first and second ingress content processors. System cells from the first ingress content processor are automatically sent to the switch fabric while system cells from the second ingress content processor are required to be scheduled before being sent to the switch fabric. The switch fabric separately queues system cells carrying payloads associated with the first traffic type from system cells carrying payloads associated with the second traffic type. The switch fabric services system cells carrying payloads associated with the first traffic type prior to servicing system cells carrying payloads associated with the second traffic type.

摘要： A system supports 50 ms protection switching times independent of network architecture. The system includes multiple protection switch fabrics to perform facility protection switching for the signals and a central switch fabric to switch a subset of the signals in a non-facility protection switching manner among the protection switch fabrics. Linear and ring network configurations are supported by the system. The system has flexibility to perform Linear Automatic Protection Switching (LAPS), Unidirection Path Switched Ring (UPSR) protection switching, and Bidirectional Line Switched Ring (BLSR) protection switching without burdening the central switch fabric with unnecessary or redundant traffic.
