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： Data path processing information is included in the pseudowire layer of pseudowire packets in order to provide information for use in the data path processing of data (e.g., a packet), typically, but not always, included in the payload of the pseudowire packet itself. The pseudowire packet typically includes in corresponding fields: a pseudowire label for identifying a pseudowire type; a pseudowire control word; and payload data. The pseudowire type identifies the structure of the pseudowire control word field and the payload field, including the location of data path meta data, such as in the pseudowire control word field or payload field. This data path meta data identifies one or more attributes for use in processing the payload data.

摘要： In one embodiment, packets received at head-end nodes in a computer network may have a payload and protocol ID of an original protocol of the packet. To allow load balancing across the network, the head-end node may convert the protocol ID to indicate a UDP packet, and may insert a UDP shim header into the packet having a load balance ID, at least one port ID of a destination tail-end node of the packet, and an indication of the original protocol ID. The head-end node may transmit the converted UDP packet toward the tail-end node as part of a load-balanced UDP flow based on the load balance ID. Tail-end nodes may receive UDP packets, and determine whether they are converted UDP packets. If so, the original protocol of the packet may be determined, the UDP header may be removed, and the packet may be processed according to the original protocol.
摘要翻译：在一个实施例中，在计算机网络中的头端节点处接收的分组可以具有分组的原始协议的有效载荷和协议ID。为了允许跨网络的负载平衡，前端节点可以将协议ID转换为指示UDP分组，并且可以将UDP垫片头部插入到具有负载均衡ID的分组中，至少一个目的地尾部的端口ID，分组的终端节点，以及原始协议ID的指示。基于负载平衡ID，头端节点可以将转换的UDP分组作为负载平衡UDP流的一部分向尾端节点发送。尾端节点可以接收UDP分组，并确定它们是否是转换的UDP分组。如果是这样，则可以确定分组的原始协议，可以去除UDP报头，并且可以根据原始协议来处理分组。

摘要： An application node advertises service(s), using a routing protocol, that it offers to other network nodes. For example, the routing protocol used to advertise service(s) in a Service Provider Network is typically an link-state, Interior Gateway Protocol (IGP), such as, but not limited to, Intermediate System to Intermediate System (IS-IS) or Open Shortest Path First (OSPF). Packets are encapsulated and sent from a service node (e.g., packet switching device) using one or more advertised services applied to a packet by an application node (e.g., a packet switching device and/or computing platform such as a Cisco ASR 1000).
摘要翻译：应用程序节点使用其提供给其他网络节点的路由协议来通告服务。例如，用于在服务提供商网络中通告服务的路由协议通常是链路状态内部网关协议（IGP），例如但不限于中间系统到中间系统（IS-IS）或开放最短路径优先（OSPF）。使用由应用节点（例如，分组交换设备和/或诸如Cisco ASR 1000的计算平台）应用于分组的一个或多个通告的服务，将分组封装并从服务节点（例如，分组交换设备）发送。

摘要： An application node advertises service(s), using a label distribution protocol, that it offers to other network nodes and a corresponding label to use to identify these services(s). For example, a Targeted Label Distribution Protocol (tLDP) session may be established between a packet switching device and the application node providing these services to communicate the advertisement. Packets are encapsulated and sent from a service node (e.g., packet switching device) with the corresponding label to have one or more advertised services applied to the packet by an application node (e.g., a packet switching device and/or computing platform such as a Cisco ASR 1000).
