Abstract
The present disclosure discloses a service chain routing method and system, and equipment in the system, wherein, the service chain routing method includes that: a relay node receives a first data message forwarded by a switching node, wherein the first data message is a message sent to a next-hop node which does not support service chain routing, and the relay node forms a binding relationship with the next-hop node; after determining that a type of the next-hop node is a service node, the relay node deletes a service chain identifier in the first data message; and the relay node sends the first data message in which the service chain identifier is deleted to the switching node, as to the switching node to forward, according to the binding relationship, the first data message in which the service chain identifier is deleted to the next-hop node.
