Abstract:
An SFC-based communications method and system, and an apparatus are provided. The SFC includes a CF node, an SFF node, and an SF node, and the SFF node is connected to the SF node. The method includes: receiving, by the CF node, a first message from the SFF node; obtaining, by the CF node, network topology information of the SFC based on the first message; obtaining, by the CF node, an SFC forwarding table, where the SFC forwarding table is determined based on the network topology information of the SFC; and sending, by the CF node to the SFF node, a second message used to indicate the SFC forwarding table. In this way, a network topology of the SFC can be flexibly and efficiently discovered.

Claim (Index 18):
A classifier (CF) node in a service function chain (SFC), wherein the SFC comprises the CF node, a service function forwarder (SFF) node, and a service function (SF) node, the SFF node is connected to the SF node, and the CF node comprises:\n a non-transitory memory storing instructions; and a processor coupled to the non-transitory memory; wherein the instructions, when executed by the processor, cause the CF node to: receive a first message from the SFF node, wherein the first message comprises identification information and attribute information of the SFF node, and identification information and attribute information of the SF node; obtain network topology information of the SFC based on the first message received by the CF node, wherein the network topology information of the SFC comprises the identification information and the attribute information of the SFF node, the identification information and the attribute information of the SF node, and information used to indicate a connection relationship between the SFF node and the SF node; obtain an SFC forwarding table, wherein the SFC forwarding table is determined based on the network topology information of the SFC that is obtained by the CF node; and to send, to the SFF node, a second message used to indicate the SFC forwarding table obtained by the CF node, so that the SFF node forwards a data packet based on the SFC forwarding table.
