Abstract: A segment routing-based data transmission method includes that a first network device receives a first packet from a second network device, where the first packet includes a first segment identifier (SID); the first network device obtains, based on the first SID, a first network slice identifier corresponding to the first network device; the first network device generates a second packet based on the first packet, where the second packet includes the first network slice identifier; and the first network device sends the second packet.

Abstract: A method and apparatus for implementing multicast. When a multicast source performs route advertisement, route update is performed on a cross-DC integrated device, and a received device identifier and a received AS number are replaced with a device identifier and an AS number that are of the integrated device. In this way, when a multicast user joins the multicast source, each network device in the network can trace the multicast source based on a received route, and determine a multicast path that is from the multicast source to the multicast user. Therefore, it is possible to accurately perform, in a NG MVPN, cross- DC multicast on traffic of the multicast source.

Abstract: A method is applied to a network comprising a first area and a second area. A first node in the first area obtains aggregated routing information, where the aggregated routing information is obtained by aggregating a plurality of pieces of original routing information, the plurality of pieces of original routing information correspond to N nodes in a network segment, the N nodes in the network segment have a same flexible algorithm flex-algo, and the aggregated routing information carries an algorithm identifier used to indicate the flex-algo and a network segment identifier used to indicate the network segment. The first node sends the aggregated routing information to the second area, where the aggregated routing information is used to indicate a node in the second area to send a packet to the N nodes in the network segment based on the aggregated routing information.

Abstract: The method of establishing a multicast data channel in a network virtualization system includes: creating, on a controller, a virtual remote logical interface for an external interface of a remote node; generating, a multicast tree tunnel that uses a core node as a root, and obtaining a multicast protocol packet sent by a device outside the network virtualization system; acquiring, a multicast source address and a multicast group address from the multicast protocol packet, and generating a multicast forwarding table; searching, the multicast forwarding table for an external interface of the core node, searching for an outbound interface of the multicast tree tunnel on the core node according to the multicast tree tunnel, and generating a P2MP PW forwarding table of the core node, and sending the P2MP PW forwarding table of the core node to the core node. The method implements a multicast service in a virtual cluster router.
