Abstract: A method for generating forwarding information includes determining, by a controller, a first service forwarding entity (SFE) and a second SFE forwarding a service stream, where the first SFE and the second SFE are on a service function chain corresponding to the service stream, generating, by the controller, first forwarding information for the first SFE and second forwarding information for the second SFE, and sending, by the controller, the first forwarding information to the first SFE and sending the second forwarding information to the second SFE. Hence, the controller generates forwarding information for the SFE such that a service chaining technology can be applied to a service environment in which a large quantity of services and a large quantity of service processing function units exist.

Abstract: The present invention provides an access method and system of a customer premise equipment, and a broadband network gateway. The access method of a customer premise equipment includes: receiving, by a BNG in a BNG pool, an access request packet sent by a CPE, where the access request packet carries an identifier of a CPE group to which the CPE belongs; and obtaining, by the BNG, an access policy of the CPE group according to the identifier of the CPE group, and performing access control on the CPE according to the access policy. Through the present invention, a BNG in a BNG pool is enabled to provide an access service for a CPE according to an access policy, so that when a BNG in a BNG pool is faulty, a BNG that is not faulty in the BNG pool can provide an access service for a CPE originally accessing the faulty BNG, thereby improving the reliability of the entire network.

Abstract: Embodiments of the present invention disclose a method and a gateway device for managing an address resource, which relate to the field of Internet technologies and can maximally reduce horizontal traffic between gateway devices, thereby improving system performance. The method in the present invention includes: sending an address delegation request message to a management gateway device in a same gateway group, where the management gateway device is configured to manage an address pool(s) or an address in an address pool; receiving a response message sent by the management gateway device, where the response message includes a delegated address, and the delegated address is an address in the address pool(s) managed by the management gateway device; acquiring the delegated address in the response message; and allocating an address in the delegated address to a user terminal in a same user group. The present invention is used for managing the address resource.

Abstract: The embodiments of the present invention disclose a method, apparatus and system for implementing routing aggregation, which relate to communication field, and solve the problem that too many routings advertised on the DHCPv6 relay agent leads to huge number of routing table entries of the backbone network. The technical solution of the present invention comprises: sending a message to a dynamic host configuration protocol DHCPv6 relay agent, such that the DHCPv6 relay agent generates an aggregation routing of requesting router prefix routings according to the message; wherein the message comprises information about a prefix pool which assigns address prefixes to the requesting routers access to the DHCPv6 relay agent or aggregation routing destination address information generated according to the information about the prefix pool. The method, apparatus and system for implementing routing aggregation may be applied in DHCPv6 network constructions.
