Abstract: The present disclosure provides a routing management method and apparatus, a network device, and a readable storage medium. The method comprises: a controller obtaining network topology information of a network side; the controller calculating, on the basis of the network topology information, path information of a segment routing traffic engineering (SR-TE) instance to be created, and sending the path information to a header node of the network side, wherein the path information comprises segment list information and entropy label (EL) insertion position information; and the controller creating the SR-TE instance from the header node to a tail node on the network side.

Abstract: The present disclosure provides a packet processing method applied to a first edge device, including: sending a route advertisement message of a virtual private network to a second edge device, the route advertisement message indicating whether the first edge device supports a first network architecture and whether the first edge device supports a second network architecture, the first edge device supporting at least one of the first network architecture or the second network architecture; and receiving a second service packet sent by the second edge device, where the second service packet is obtained by the second edge device in response to a first service packet according to the network architecture supported by the first edge device. The present disclosure further provides a packet processing method applied to a second edge device, an edge device, and a computer-readable storage medium.

Abstract: Provided is a virtual circuit-based data packet processing method, which includes that: identification information of a next-hop Provider Edge (PE) node of a routing packet and identification information of an Original PE (OPE) node of the routing packet are determined according to the routing packet corresponding to a Virtual Private Network (VPN) service instance; a context virtual circuit is determined, wherein nodes at both ends of the context virtual circuit are respectively the current PE node and the OPE node; a virtual circuit label of the context virtual circuit is determined; a final data packet to be forwarded is obtained 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 the final data packet to be forwarded is forwarded to the next-hop PE node.
