摘要： A method is disclosed of forwarding data in a data communications network comprising a plurality of nodes and links therebetween, each link having an associated usage cost and a load capacity. A forwarding node identifies a lowest cost route, comprising one or more links, to a destination node. If a plurality of lowest cost routes is identified, then the forwarding node allocates data for forwarding along each of the lowest cost routes dependent on a relative load capacity of that route.

摘要： A method and apparatus are disclosed for generating routing information in a data communications network. A first network element (such as a router) receives information relating to a second network element, such as another node or a network link. In response, the first network element determines whether the information relating to the second network element indicates a change in the network. When information relating to a second network element indicates a change in the network, the first network element determines a new shortest path through the network from the first network element for each network element in the network. After a delay, the first network element updates routing information for the first network element based on the new shortest path for the first network element. Preferably the delay is proportional to the distance of the first network element from the second network element.

摘要： In one embodiment, a connectivity verification protocol (CVP) session for a particular virtual interface (VI) may operate on a particular group of two or more line cards (LCs) on a network device. The group of LCs may then transmit CVP session packets, at a reduced rate that is sufficient to maintain the CVP session based on a negotiated CVP full rate, onto the particular VI through ingress path processing on the network device. Ingress path processing, in particular, takes transmitted CVP session packets and egresses them onto an appropriate LC of the network device currently responsible for the VI egress. Also, in response to receiving CVP session packets for the VI on an LC of the network device currently responsible for the VI ingress, the receiving LC may forward the received CVP session packets to the particular corresponding group of LCs, which may then process the received CVP session packets.
摘要翻译：在一个实施例中，用于特定虚拟接口（VI）的连接性验证协议（CVP）会话可以在网络设备上的两个或更多个线路卡（LC）的特定组上操作。然后，该组LC可以以足以将CVP会话基于协商的CVP全速率维持在该网络设备上的入口路径处理的CVP会话分组发送到特定VI上。进入路径处理，特别是将传输的CVP会话数据包发送到当前负责VI出口的网络设备的适当LC上。此外，响应于当前负责VI入口的网络设备的LC上接收到用于VI的CVP会话分组，接收LC可以将接收到的CVP会话分组转发到特定对应的LC组，然后可以处理接收到的 CVP会话数据包。

摘要： In one embodiment, a router receives a real-time multimedia flow that comprises IP packets. The router then processes values included in the Identifier fields of the IP packets using resources similar to those used in the monitoring of RTP flows to identify metrics for the real-time multimedia flow. The metrics may be transferred to a remote management device for aggregation with metrics output by other routers located on the data path for the real-time multimedia flow.
