摘要： A method of requesting reservation of a label switched path (LSP) for traffic of a type compatible with ITU-T G709 amendment 3, in an optical transport network by sending a RSVP-TE path message for the reservation of the requested LSP from an ingress node (10) of the requested path, via intermediate nodes (40) along the path to an egress node (70), and sending a RSVP-TE resv message from the egress node, to cause the nodes to reserve resources for the requested path. The path message has a signal type field having values assigned to indicate traffic types specified in G.709 amendment 3 beyond those specified by G.709 pre amendment 3, without reuse of values specified by G.709 pre amendment 3. Since the nodes along the path can still distinguish in the signal type field any values of the signal type field specified by G.709 pre amendment 3, new nodes can still work with legacy messages.
摘要翻译：一种在光传输网络中请求预留用于与ITU-T G709修订版3兼容的类型的业务的标签交换路径（LSP）的方法，通过从入口发送用于预留所请求的LSP的RSVP-TE路径消息所述请求路径的节点（10）经由经由到所述出口节点（70）的路径的中间节点（40）发送，并且从所述出口节点发送RSVP-TE RESV消息，以使所述节点预留所请求路径的资源。路径消息具有信号类型字段，其值被分配用于指示G.709修正3中规定的超出G.709预修改3所指定的业务类型，而不重用由G.709预修改3指定的值。由于节点路径仍然可以在信号类型字段中区分由G.709预修改3指定的信号类型字段的任何值，新节点仍然可以与旧消息一起使用。

摘要： Control of a label switched path (12) established in a network (10) is transferred between a management plane and a control plane of the network. A node (C) receives a message indicating a change in control of the label switched path (12), the message identifying the label switched path by a cross-connection identifier corresponding to an entry (54) in the control data (52) stored at the node which identifies data plane ingress and egress segments cross-connected at the node. Control data at the node is updated based on the identified label switched path (12). The message includes a list of cross-connection identifiers for nodes (C,E,F) along the label switched path (12). The cross-connection identifier can be an mplsXCIndex.

摘要： Setting up a label switched path (LSP) for traffic between nodes of a network, involves sending a request message requesting reservation of resources for the requested LSP, from an ingress node (10) via intermediate nodes (40) and returning an acknowledgement message to an upstream node along the path. Absence of an acknowledgement from the downstream node, that the request message was received, is detected. Whether the given node should react to the detected absence can be determined from an indication (R) in the request message. Thus other nodes can react more quickly to take remedial action, to reroute or to remove the resource reservations without a long wait for a time out or a refresh message from the waiting ingress node, to enable more efficient use of the resources.
摘要翻译：为网络节点之间的流量设置标签交换路径（LSP）涉及从入口节点（10）经由中间节点（40）发送请求预留所请求的LSP的资源的请求消息，并将确认消息返回沿着路径的上游节点。检测到从下游节点没有接收到请求消息的确认。是否可以根据请求消息中的指示（R）确定给定节点对检测到的不存在的响应。因此，其他节点可以更快地做出反应以采取补救措施，重新路由或删除资源预留，而不需要等待超时或等待的入口节点的刷新消息，才能更有效地利用资源。

摘要： A connection-oriented network (5) has a point-to-multipoint working path (10) between a source node (A) and a plurality of destination nodes (B-F). On detection of a failure in the working path, an indication of the failure is sent to a first node (e.g. node A) identifying the point of failure. The indication is sent via a control plane of the network. The first node selects one of a plurality of point-to-multipoint backup paths (21-25) based on the point of failure. Each backup paths connects the first node to the plurality of destination nodes. There is a point-to-multipoint backup path (21-25) for each of a plurality of possible points of failure along the working path. The backup paths (21-25) can be pre-configured to carry traffic in advance of the detection of failure. Alternatively, the first node can signal to nodes of the selected backup path to fully establish the backup path when it is required.

摘要： The present invention relates to configuring the quality of service in a label switched network. In particular, the invention relates to configuring quality of service for the return path of a bi-directional label switched path in a label switched network. The invention provides a method of configuring quality of service for a return path of a bi-directional label switched path within a network, the bi-directional label switched path having a forward path and a return path. A label information context for a quality of service configuration of the return path of a label switched path is configured separately from a quality of service configuration for the forward path. Path set up messages are formed containing a return path quality of service object indicating the quality of service configuration for the return path separately from a quality of service configuration for the forward path.

摘要： A connection-oriented network (6) has a first working path (W1) and a second working path (W2). A node (E) receives signalling to allocate resources for a part of a recovery path (R1) for the first working path (W1). The resources are shared by the recovery path (R1) for the first working path and a recovery path (R2a) for the second working path (W2). The node (E) stores an association between the shared resources and a node (A) on the first working path, identified in the signalling, which should be notified when the shared resources are used by the recovery path (R2a) for the second working path (W2). An RSVP-TE object in the signalling carries an address of the node to be notified. The node (E) sends an RSVP-TE Notify message to a node (A) on the first working path (W1) which indicates that the shared resources are in use.

摘要： A label switched path through a network of nodes, is torn down by sending a message along the path from an ingress node. If there is a fault along the path, a path error message (2) is sent back along the path to the ingress node. The ingress node uses a different route bypassing the fault to alert (3) a further one of the nodes (NE5, NE6) on that path beyond the indicated fault, to cause that further node to continue the tearing down for other nodes on that path beyond the indicated fault by sending a further message (4) along the portion of the path beyond the indicated fault, to indicate to the other nodes to continue the tear down. This enables the ingress node to clean up the rest of the path beyond the fault, to avoid leaving unused capacity unavailable for reuse, and to avoid time consuming manual clean up.

摘要： In one example aspect, a method is provided for tearing down a label switched path (LSP) through a communications network. The method comprises sending a first message towards an egress node of the LSP informing nodes of the LSP and the egress node of a tear down of the LSP, determining that one of the nodes of the LSP has not forwarded the first message along the LSP, and sending a second message to a controller of the communications network to cause the controller to communicate directly with the one of the nodes to inform the one of the nodes of the tear down of the LSP.
