Claim 0:
1. A virtual circuit-based data packet processing method, which is applied to a Provider Edge (PE) node and comprises:
determining, according to a routing packet corresponding to a Virtual Private Network (VPN) service instance, identification information of a next-hop PE node of the routing packet and identification information of an Original PE (OPE) node of the routing packet, wherein the VPN service instance is deployed on a current PE node and the OPE node;
determining a context virtual circuit, wherein nodes at both ends of the context virtual circuit are respectively the current PE node and the OPE node;
determining a virtual circuit label of the context virtual circuit;
obtaining a first final data packet to be forwarded by carrying a VPN label of the routing packet and the virtual circuit label with an initial data packet of the VPN service instance; and
forwarding the first final data packet to be forwarded to the next-hop PE node.
