Abstract: A method of implementing a service chain in a service chain-enabled domain network includes: receiving, by an intermediate service node (SN), an extended first Border Gateway Protocol (BGP) packet from a downstream SN that is on a service chain path and immediately adjacent to the intermediate SN, the extended first BGP packet including a service chain path identifier identifying the service chain path and a first service chain path including a service chain path from an ingress SN to the intermediate SN, determining an upstream SN that is on the first service chain path and immediately adjacent to the intermediate SN, and sending an extended second BGP packet to the upstream SN, the extended second BGP packet including the service chain path identifier and a second service chain path including a service chain path from the ingress SN to the upstream SN.

Abstract: This application discloses a method for implementing communication between an NVO3 network, to implement inter-AS communication between an NVO3 network and an MPLS VPN network. The method includes: obtaining an identifier of a PE device in the MPLS network and an MPLS label allocated by an ASBR in the MPLS network; allocating an IP address for the MPLS label from a local address pool; sending routing information to an NVE, where the routing information includes an identifier of the PE device and the allocated IP address, and the allocated IP address is used as an outer destination address of an NVO3 encapsulated packet sent by a TES in the NVO3 network to a CE device connected to the PE device in the MPLS network.

Abstract: A control point obtains a correspondence between a plurality of groups and a plurality of access policies; determines that a user in a first group accesses a network by using a first policy enforcement point, where the first group belongs to the plurality of groups; and sends, to the first policy enforcement point, a first access policy corresponding to the first group, where the first access policy belongs to the plurality of access policies, and the first access policy is used to determine whether the first group is accessible by a second group.

Abstract: The present disclosure discloses a flow specification (FlowSpec) message processing method. In the method, a controller forwards device interface information reported by the forwarding device; selects at least one forwarding device interface to which a FlowSpec rule needs to be applied from the received forwarding device interface information; generates an application interface rule based on the at least one forwarding device interface to which the FlowSpec rule needs to be applied; and sends a FlowSpec message to the forwarding device.

Abstract: A route processing method includes obtaining, by a first network device, a flow effective time parameter and a route related to the flow effective time parameter, processing, by the first network device in the specified time interval, service traffic corresponding to the route related to the flow effective time parameter, generating a route control message, where the route control message carries the flow effective time parameter and the route, and sending, by the first network device, the route control message to a second network device.

Abstract: A route processing method, a device, and a system, where the method includes obtaining, by a first network device, a flow effective time parameter and a route related to the flow effective time parameter, processing, by the first network device in the specified time interval, service traffic corresponding to the route related to the flow effective time parameter, generating a route control message, where the route control message carries the flow effective time parameter and the route, and sending, by the first network device, the route control message to a second network device. Therefore, limited-time effective information is automatically disseminated, a limited-time effective requirement for a traffic control policy is met, configuration workload is reduced, and maintenance difficulty is lowered.
