Abstract: The present application provides a redirection method, apparatus, and system, to increase a redirection success rate. In the method, a broadband remote access server (BRAS) receives a first Transport Layer Security (TLS) handshake packet sent by a terminal, where the first TLS handshake packet carries a flag and an identifier of the terminal, and the flag is used to indicate that the terminal is capable of performing redirection according to a uniform resource locator (URL); after determining that the first TLS handshake packet carries the flag, the BRAS obtains a URL of a destination server and a certificate of the destination server according to the identifier of the terminal, where the destination server is a server that redirection is destined for; and the BRAS sends the URL of the destination server and the certificate of the destination server to the terminal.

Abstract: The present application provides an IPv6 address tracing method, apparatus, and system, where the method includes: receiving a to-be-traced target IPv6 address; selecting, in a longest match manner, IPv6 address information that matches the target IPv6 address, where the IPv6 address information includes an IPv6 address or IPv6 prefix information; and acquiring a user identifier corresponding to the IPv6 address information. The present application implements IPv6 address tracing.

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.

Abstract: Embodiments of the present invention provide an information providing method, a home gateway, and a home network system. The method includes: obtaining an IPv6 address or an IPv6 prefix of a client and a service type of the client; establishing a mapping between the IPv6 address or the IPv6 prefix of the client and the service type of the client; sending the mapping between the IPv6 address or the IPv6 prefix of the client and the service type of the client to a Broadband Remote Access Server (BRAS), so that the BRAS dispatches and manages a service of the client according to the mapping between the IPv6 address or the IPv6 prefix of the client and the service type of the client.

Abstract: A method for providing user information to a CGN device, includes: receiving, by the RADIUS server, accounting start request information of a user sent by the BRAS device, where the accounting start request information carries user information of the user, and the user information includes: a user identity and management information of the user; and sending, by the RADIUS server, the user information to a CGN device, so that the CGN device is capable of performing network management on the user according to the user information.
