Connectivity protocol delegation

摘要

In general, techniques are described for delegating responsibility for performing a connectivity protocol from one or more endpoint devices to network infrastructure situated along a network forwarding path connecting the endpoint devices. In some examples, an intermediate network device includes a connectivity protocol module of control unit that operates a connectivity protocol session on behalf of a server, wherein the server exchanges application data with the client using an application-layer communication session with the client. The connectivity protocol module monitors connectivity for the application-layer communication session with the connectivity protocol session by exchanging connectivity protocol messages for the connectivity protocol session with the client to determine a connectivity status for the communication session. The connectivity protocol module updates the server with the connectivity status for the communication session by sending a summary report message that includes the connectivity status for the communication session to the server.

1. A method comprising:
receiving, by a network device situated on a bidirectional forwarding path connecting a server and a client of the server, a delegation request from the server, the delegation request specifying parameters for a connectivity protocol session for monitoring connectivity for an application-layer communication session between an application executing on the server and an application executing on the client, the parameters including a unique identifier for the application executing on the server; sending, by the network device to the client in response to the receiving the delegation request and in accordance with the parameters for the connectivity protocol session, application-layer data that includes connectivity protocol messages for the connectivity protocol session with the client to determine a connectivity status for the application-layer communication session, wherein each of the connectivity protocol messages specifies the unique identifier; and sending, by the network device, a summary report message that includes the connectivity status for the application-layer communication session to the server.
