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).
