摘要： One example embodiment of the method includes receiving first control packets, by a first node, from a source node. The first control packets indicate the status of the source node. Whether the source node is operational and if a connection path between the first node and the source node is operational is determined based on the received first control packets. The method further includes sending a second control packet to a downstream node if the source node is non-operational, or the connection is non- operational. The second control packet includes at least one value indicating the source node is unreliable.

摘要： A multicast path trace capability is provided for tracing a multicast path from a root node to a leaf node where the trace originates at the leaf node. The leaf node sends a multicast trace request to the root node. The root node receives the multicast trace request and initiates a path trace request for collecting path information associated with the multicast path. The root node receives at least one path trace response, in response to the path trace request, which includes path information associated with the multicast path. The root node sends a multicast trace response, including the collected path information, to the leaf node. The leaf node receives the multicast trace response including the path information. The leaf node derives end-to-end path information for the multicast path using the path information received in the multicast trace response. The multicast path trace capability may be used for tracing an MPLS multicast path (e.g., a P2MP LSP) from a root node to a leaf node of the MPLS multicast tree. The multicast path trace capability may be used for tracing multicast paths in other types of multicast networks.
摘要翻译：提供了组播路径跟踪功能，用于跟踪从根节点到叶节点的组播路径，其中跟踪始于叶节点。叶节点向根节点发送组播跟踪请求。根节点接收组播跟踪请求，并发起路径跟踪请求，收集与组播路径相关的路径信息。根节点响应于包括与多播路径相关联的路径信息的路径跟踪请求，接收至少一个路径跟踪响应。根节点向叶节点发送包括收集的路径信息的组播跟踪响应。叶节点接收包括路径信息的组播跟踪响应。叶节点使用在多播跟踪响应中接收到的路径信息来导出多播路径的端到端路径信息。组播路径跟踪功能可以用于跟踪MPLS组播树的根节点到叶节点的MPLS组播路径（例如，P2MP LSP）。组播路径跟踪功能可用于跟踪其他类型组播网络中的组播路径。

摘要： A capability is provided for switching between primary and standby multicast trees on a network egress node of a multicast network. The network egress node includes a first MPLS LABEL Record including a first tree identifier of the first multicast tree, a second MPLS LABEL Record including a second tree identifier of the second multicast tree, and a MULTICAST Record including a plurality of primary tree identifiers and a plurality of standby tree identifiers. The MPLS LABEL Records include parameters, respectively, where the values of the parameters are indicative of respective packet processing rules to be applied for determining whether to accept or discard packets. When the parameter of an MPLS LABEL Record is set to a first value, a determination as to whether to accept or discard a packet received via the associated multicast tree is performed by comparing the tree identifier of the MPLS LABEL Record only to primary tree identifiers of the MULTICAST Record. When the parameter of an MPLS LABEL Record is set to a second value, a determination as to whether to accept or discard a packet received via the associated multicast tree is performed by comparing the tree identifier of the MPLS LABEL Record to primary tree identifiers of the MULTICAST Record or standby tree identifiers of the MULTICAST Record.
摘要翻译：提供了用于在组播网络的网络出口节点上的主要和备用组播树之间进行切换的能力。网络出口节点包括包括第一多播树的第一树标识符的第一MPLS标签记录，包括第二多播树的第二树标识符的第二MPLS LABEL记录和包括多个主树标识符的MULTICAST记录和多个备用树标识符。 MPLS LABEL记录分别包括参数，其中参数的值表示要应用于确定是否接受或丢弃分组的各个分组处理规则。当MPLS标签记录的参数被设置为第一值时，通过将MPLS LABEL记录的树标识符与仅主节点标识符的主树标识符进行比较来执行是否接受或丢弃经由相关联的多播树接收的分组的确定 MULTICAST记录。当MPLS LABEL记录的参数设置为第二个值时，通过将MPLS LABEL记录的树形标识符与对应的多播树的主树标识符进行比较来执行是否接受或丢弃通过关联的多播树接收到的数据包的确定 MULTICAST MULTICAST记录的记录或备用树标识符。
