摘要： In one embodiment, a network device determines identities of each peer device in a second routing domain attached to edge devices in a first routing domain. The network device associates each address prefix reachable in the second routing domain with an identity of each peer device in the second routing domain that advertised the address prefix and with an identity of one or more edge devices in the first routing domain to which that peer device is attached. The network device determines an address prefix is associated with a same identity of a peer device in the second routing domain but with different edge devices in the first routing domain. The network device assigns the different edge devices in the first routing domain associated with the determined address prefix to a shared risk node group (SRNG).

摘要： In one embodiment, one or more tunnel mesh groups may be established in at least a portion of a computer network, where each tunnel mesh group corresponds to a differentiated routing profile. Traffic may then be received at the portion of the computer network, the traffic indicating a particular differentiated routing profile (e.g., based on a received label corresponding to the differentiated routing profile as advertised by the portion of the computer network). Accordingly, the traffic may be routed through the portion of the computer network along a tunnel of a particular tunnel mesh group corresponding to the particular differentiated routing profile traffic.
摘要翻译：在一个实施例中，可以在计算机网络的至少一部分中建立一个或多个隧道网格组，其中每个隧道网格组对应于不同的路由简档。然后可以在计算机网络的部分处接收业务，该业务指示特定差分路由配置文件（例如，基于与该计算机网络的部分所通告的差分路由配置文件对应的接收到的标签）。因此，业务可以沿着与特定差异化路由选择业务对应的特定隧道网状组的隧道路由到计算机网络的部分。

摘要： In one embodiment, a device of a particular non-backbone routing domain in a computer network determines whether each of one or more routes is reachable within the particular non-backbone domain. The device may then generate a filtered set of label mappings having only those of the one or more routes reachable within the particular non-backbone domain. Accordingly, the device may advertise label mappings only of the filtered set to one or more neighboring devices.

摘要： In one embodiment, an apparatus in a network determines particular metadata to communicate infrastructure information associated with a particular packet to another apparatus in the network. The apparatus sends into the network the particular packet including a metadata channel, comprising said particular metadata, external to the payload of the particular packet. Examples of infrastructure metadata carried in a packet include, but are not limited to, information defining service chaining for processing of the packet, contextual information for processing of the packet, specific handling instructions of the packet, and operations, maintenance, administration (OAM) instrumentation of the packet.

摘要： Routes advertised in a network may include an Internet Protocol (IP) address and one or more values to distinguish the route from other route(s) including the same IP address. Routes in a same context (e.g., within a same Virtual Private Network or for an entire network) with a same IP address are considered to refer to a same destination. When these routes are associated with different paths through a network, these different paths can be used to forward traffic for packets associated with routes including a same IP address (in a same context), particularly in response to a network problem.
摘要翻译：在网络中通告的路由可以包括因特网协议（IP）地址和一个或多个值以区分路由与包括相同IP地址的其他路由。具有相同IP地址的相同上下文（例如，在相同的虚拟专用网络或整个网络内）的路由被认为是指相同的目的地。当这些路由与通过网络的不同路径相关联时，这些不同的路径可以用于转发与包括相同IP地址（在相同上下文中）的路由相关联的分组的流量，特别是响应于网络问题。

摘要： Packets are encapsulated and sent from a service node to one or more application nodes for applying one or more Layer-4 to Layer-7 services to the packets. Before which for a packet, the service node performs a lookup operation based on a destination address of the packet in a routing data structure derived from a exterior network protocol, such as, but not limited to Border Gateway Protocol (BGP). This lookup operation results in the identification of a next hop packet switching device to which the packet would be sent from the service node. The service node includes this identification of the next hop address in the request packet sent to the application node(s). After the service(s) are applied to the packet, an application node will send the services-applied packet to this next hop address. In this manner, application nodes do not need to run an exterior network protocol. Although, they typically will run an Interior Gateway Protocol for identifying how to forward packets to the next hop address.
摘要翻译：分组被封装并从服务节点发送到一个或多个应用节点，以将一个或多个第4层到第7层服务应用于分组。在分组之前，服务节点基于来自外部网络协议（例如但不限于边界网关协议（BGP））的路由数据结构中的分组的目的地地址来执行查找操作。该查找操作导致从服务节点发送分组的下一跳分组交换设备的标识。服务节点包括发送到应用节点的请求分组中的下一跳地址的标识。应用程序节点将该服务应用于数据包后，将将应用服务的数据包发送到下一跳地址。以这种方式，应用节点不需要运行外部网络协议。虽然，它们通常将运行内部网关协议，用于识别如何将数据包转发到下一跳地址。

摘要： In one embodiment, a communications distribution process maintains at least two pseudowires through a network such that the pseudowires share a burden of delivering data through the network. The communications distribution process receives feedback data concerning operation of each pseudowire. The communications distribution process utilizes the feedback data to distribute communications to the common destination across each of the pseudowires. Additionally, the communications distribution process utilizes the feedback to establish at least one new pseudowire, in addition to the first pseudowire and the second pseudowire, for transmission of data traffic.
