摘要： In one example, techniques of this disclosure may enable a point of local repair (PLR) network device to signal availability of link protection or node protection to a merge point (MP) network device and enable a network device to actively determine whether or not it is a merge point router. Based on whether or not the network device determines it is a MP, the network device may selectively clean up LSP states when there is an upstream link or node failure. The RSVP-TE protocol may be extended to enable a network device to send a tear down message to a downstream router, which may enable the downstream router to conditionally delete locale LSP state information. In some instances, a PLR network device may directly send a tear down message to a MP network device even though the PLR network device may not have a working bypass LSP.
摘要翻译：在一个示例中，本公开的技术可以使得本地修复（PLR）网络设备的点能够向合并点（MP）网络设备通知链路保护或节点保护的可用性，并使得网络设备能够主动地确定其是否是一个合并点路由器。基于网络设备是否确定它是MP，当存在上游链路或节点故障时，网络设备可以选择性地清除LSP状态。可以扩展RSVP-TE协议以使网络设备向下游路由器发送撕下消息，这可以使下游路由器有条件地删除区域性LSP状态信息。在一些情况下，即使PLR网络设备可能没有工作旁路LSP，PLR网络设备也可以直接向MP网络设备发送拆卸消息。

摘要： Methods and systems for resource reservation networks configured to maintain low latency and latency variation of co-shared sessions. A session creation module (SCM) creates a bi-directional parent session (Sp), between first and second session partners, by: allocating co-shared network resources over a first network hop, and allocating network resources over a second network hop; wherein the network resources allocated to the Sp guarantee a maximum end-to-end latency variation (e2eLV) below 100 usec. The SCM further calculates a maximum e2eLV of a potential bi-directional derivative session (Sd) between the first session partner and a third session partner; wherein the potential Sd utilizes network resources over a third network hop and the co-shared network resources over the first network hop. And the SCM creates the Sd responsive to determining that the maximum e2eLV of the Sd being below 100 usec.

摘要： A method implemented by an apparatus for providing spare capacity allocation (SCA) for dual link failures in a network. The SCA scheme computes the SCA for each of a plurality of flows in the network for a plurality of primary backup paths corresponding to a plurality of disjoint working paths for the flows using a first integer linear programming (ILP) model. The SCA scheme further computes the SCA for each of the flows for a plurality of secondary backup paths corresponding to the disjoint working paths and the primary backup paths using a second ILP model and the computed spare capacity information for the primary backup paths. The SCA scheme further aggregates the computed SCA for the primary backup paths and the secondary backup paths for all the flows.

摘要： A reservation request is received for a data transport session. The reservation request contains a requested class of communication service through the asynchronous network. The state of the network along the route is then preferably determined and at least one end-to-end route through the network is obtained. The route is based on the requested class of communication service and the state of the network. The data transport session is then controlled, such that data is forced to travel along at least one route through the asynchronous network. This is preferably done by controlling multiple data controllers dispersed along the at least one route by mapping specific data protocols to specific routes, or mapping specific data protocols to specific ports in each data controller. If a state of the asynchronous network indicates that the route cannot transport data in conformity to the class of communication service, then the route is changed to a backup route through the network.

摘要： A method for processing data packets in a communication network includes establishing a path for a flow of the data packets through the communication network. At a node along the path having a plurality of aggregated ports, a port is selected from among the plurality to serve as part of the path. A label is chosen responsively to the selected port. The label is attached to the data packets in the flow at a point on the path upstream from the node. Upon receiving the data packets at the node, the data packets are switched through the selected port responsively to the label.
