摘要： The present invention relates tonetwork nodes and methods that use an encoding scheme for encoding a point-to-multipointtraffic path (1) from one ingress node (2) to a pluralityof egress nodes (3) in e.g. a Multi-ProtocolLabel Switching network. According to the encoding scheme a so-called common ERO is used. The common ERO specifies a list consisting ofnodesthat are common to several sub paths (4) in order to provide a compression mechanism that reduces the size of path messages that are used for signaling the point-to-multipointtraffic path.

摘要： A method for establishing a downstream multicast and a upstream and downstream unicast connections between a root and at least one leaf, the root and the at least one leaf being in a tree-type configuration, comprises: creating a downstream unicast label; and distributing the created downstream unicast label in a same signaling message as downstream multicast and upstream unicast labels from the root to the at least one leaf. A network node comprising such a downstream unicast label is used to carry out the method.

摘要： The present invention relates to an ingress node (102, 700) and methods therein for Operation Administration arid Maintenance, OAM related to Resource Reservation Protocol- Traffic Engineering, RSVP-TE5 for obtaining attributes for timer values being assigned to a connection from the ingress node (102) via intermediate nodes (104, 106, 108, 110) to an egress node (112), during configuration of die connection. An interval of suitable tinier values for the intermediate nodes is specified. Configuration attributes are obtained for a timer value within an interval that is acceptable by the intermediate nodes and the egress node, based on the specified interval of suitable timer values. The obtained configuration attributes are applied during configuration of the connection from the ingress node via the intermediate nodes to the egress node, if the obtained configuration attributes are appropriate to the ingress node. Fine-tuning of connection related timers can therefore be achieved, decreasing the overall recovery time and the overall overhead.
摘要翻译：本发明涉及入站节点（102,700）及其中的操作管理和维护的方法，与资源预留协议 - 流量工程相关的OAM，RSVP-TE5，用于获得分配给来自入口节点的连接的定时器值的属性（102）经由中间节点（104,106,108,110）到出口节点（112），在管芯连接的配置期间。指定中间节点的适当值的间隔。基于指定的合适定时器值的间隔，为中间节点和出口节点可接受的间隔内的定时器值获取配置属性。如果所获得的配置属性适合于入口节点，则所获得的配置属性在从入节点经由中间节点到出口节点的配置中被应用。因此可以实现与连接相关的定时器的微调，从而减少总体恢复时间和总体开销。
