Abstract: A service node capability processing method and apparatus, a service classifier and service controller are described. The method includes: determining an exchange information set of service nodes on a service function chaining for processing a data packet, wherein the exchange information set includes an intersection of capabilities of the service nodes on the service function chaining; and encapsulating the exchange information set in the data packet, wherein the exchange information set is used for the service nodes to read a processing result which is obtained by processing capability corresponding to the intersection of the capabilities of the service nodes and which is encapsulated in the data packet. In such a fashion, the problem in the related technology is addressed that the blind information exchange causes the waste of resources since the information exchange between nodes is untargeted, and consequentially effectively avoids the waste of field resources by invalid information exchange.

Abstract: A method and device for implementing a Service Function Chain (SFC) are provided. The method is applied to a node on the SFC, and the method includes that: SFC information is encapsulated in an Internet Protocol version 6 (IPv6) of an IPv6 packet; and the IPv6 packet is sent according to the SFC information. After the IPv6 packet containing the SFC information is received, the SFC information is parsed; and an IPv6 address of a next-hop node of a Service Function Path (SFP) is acquired as a destination address, and the IPv6 packet is sent to the destination address.

Abstract: Provided are a method, device and system for implementing address sharing. An address pool configured for unified management over IP addresses is configured on an AAA server; and the AAA server may allocate an IP address to a CGN device according to the configured address pool. By such a technology for implementing address sharing in the present disclosure, IP address resource sharing among CGN devices is implemented, so that problems about resource load sharing among the CGN devices may be solved, a sharing rate of IP address resources is increased, and resource optimization may be implemented; and moreover, in terms of IP address management, a more available platform is provided for an operating company. In addition, the IP addresses are managed by the AAA server in a unified manner, and then the address pool is not required to be configured on the CGN device, so that the CGN device may be started without any address pool.

Abstract: An information transmission method, comprising: a control platform generating forwarding information of a bit indexed explicit replication (BIER) network; and the control platform sending, according to the forwarding information of the BIER network, a BIER flow table to a forwarding device through an OpenFlow protocol. The solution solves the problems that, in a forwarding mode for a multicast message in the relevant OpenFlow technology, a space occupied by an entry is larger and the forwarding efficiency is lower because it is necessary to establish a corresponding flow table and group table on each forwarding device for each flow.
