摘要： A method for merging protection switching messages in an optical network enables a control of the amount of message bandwidth used for sending protection switching messages. A method for performing protection switching in an optical network does so in an optimal manner by performing the protection switching actions in the various nodes of a protection path in parallel rather than in sequence. To do so, a channel failure message is transmitted from an end node A in the optical network upon detecting a failure in a link in the optical network that includes the end node A. If a failure can be detected at both end nodes, the channel failure messages are transmitted from both end nodes the moment they detect failure without any further waiting. Upon receiving the first channel failure message regardless its originating end node, switching actions in intermediate nodes are initiated. The channel failure messages are forwarded from the intermediate nodes to their corresponding next nodes before completing switching actions in the intermediate nodes. When receiving channel failure response messages, these messages are forwarded to a next node from the intermediate node only after switching actions are complete in the intermediate node.
摘要翻译：在光网络中合并保护倒换消息的方法能够控制用于发送保护倒换消息的消息带宽量。用于在光网络中进行保护切换的方法通过以并行方式而不是依次执行保护路径的各个节点中的保护切换动作，以最佳方式进行。为此，在检测到包括终端节点A的光网络中的链路中的故障时，从光网络中的端节点A发送信道失败消息。如果可以在两端节点检测到故障，则信道故障消息从两端节点发送，无需进一步等待即可发现故障。在接收到第一信道故障消息而不管其始发端节点时，中间节点中的切换动作被启动。在完成中间节点之间的切换动作之前，将信道故障消息从中间节点转发到其对应的下一个节点。当接收到信道故障响应消息时，只有在中间节点中的交换动作完成后，才将这些消息从中间节点转发到下一个节点。

摘要： A network architecture comprised of nodes and a transport network capable of recovering from failures within the network. The network architecture incorporates select functions into the nodes for managing the data flow between individual edge routers and their connection through core routers to the transport network. The select function allows an individual node to recover independently without signaling other nodes over the transport network. Utilizing the select function, the failure of a single core router can be recovered locally without recovery signaling over the transport network.

摘要： A technique for allocating protection-switching mechanisms operates on a per wavelength basis. This allows a designer of an optical network to select a particular protection switching mechanism for a given traffic type, which is usually specific to a particular wavelength in an optical network. For another traffic type, the designer can allocate a different protection switching mechanism, thereby providing optimal protection switching for each traffic type.

摘要： A system for routing data packets in a packet network. Packets are classified as either type-1 or type-2. Each type is routed to its destination on a smallest-delay path. However, each type can experience a different time delay between nodes in the network. Thus, the smallest-delay path for a type-1 packet may be different from that for a type-2 packet, even if the origin and destination of both types are the same. Further, these time delays can change. The invention monitors the changes, and continually identifies the smallest-delay paths for the packets.
