摘要： Techniques for providing remote access to a service provider network include exchanging multiple Dynamic Host Configuration Protocol (DHCP) formatted messages instead of any Point to Point Protocol (PPP) message to provide all PPP functions for accessing a service provider network from a customer node. The service provider network is on provider premises and the customer node is on customer premises different from the provider premises. The DHCP format is used to exchange authentication messages, user profile data on Authentication, Authorization and Accounting (AAA) servers, or session keep-alive echo messages, alone or in some combination. When all are message types are combined, these techniques provide a remote access server (RAS) with the capability to perform all functions presently provided by PPP processes. In some combinations, these techniques allow a modified DHCP server to replace a legacy AAA server.

摘要： Techniques for authenticating a user for access to an IP network include receiving from the user's host a DHCP request which includes user identifier data. A random challenge value is determined and sent to the user's host in a DHCP message format. A response message that includes a response value is received from the user's host in DHCP format. A verification value is determined based on a password value associated with the user identifier value in an AAA server and the current challenge value using a secure process that renders impractical an attempt to derive the password. If it is determined that the response value does not match the verification value, then a DHCP offer is prevented from being sent to the user's host in response to the DHCP request. Thus, a user is authenticated using DHCP instead of PPP.
摘要翻译：用于验证用户访问IP网络的技术包括从用户的主机接收包括用户标识符数据的DHCP请求。确定随机挑战值，并以DHCP消息格式发送给用户的主机。包含响应值的响应消息以DHCP格式从用户主机接收。基于与AAA服务器中的用户标识符值相关联的密码值和使用不切实际的尝试导出密码的安全过程来确定当前挑战值的验证值。如果确定响应值与验证值不匹配，则可以防止响应于DHCP请求向DHCP用户的主机发送DHCP报文。因此，使用DHCP而不是PPP进行身份验证。

摘要： In one embodiment, an edge router of a local computer network snoops client-server protocol configuration information of a customer-premises equipment (CPE) device. From the snooping, the edge router may identify an Internet Protocol version 6 (IPv6) transition option in place at the CPE device along with associated configuration parameters for the IPv6 transition option. As such, the edge router may then advertise the IPv6 transition option along with associated configuration parameters to one or more border/relay routers of the local computer network to cause the one or more border/relay routers to provision themselves with the IPv6 transition option and associated configuration parameters.

摘要： In one embodiment, a method includes receiving, by an access node, multicast control parameters for white, black, and grey lists of multicast groups. The access node applies the multicast control parameters to an IGMP process running on a port associated with a subscriber. In response to receiving an IGMP message requesting joining a multicast group, the access node either: autonomously forwarding the multicast group on the port where the multicast group in on the white list, blocking the multicast group on the port where the multicast group in on the black list, or relying on a Layer 3 broadband network gateway (BNG) to instruct the access node whether to add a forwarding entry on the port for the multicast group where the multicast group in on the grey list. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

摘要： A method, apparatus and computer program product for routing data within a packet-switched network using a PW wherein the PW is terminated directly on the layer-3 routing device such that certain services and applications can be utilized is presented. The method, apparatus and computer program product receives an encapsulated layer-2 Protocol Data Unit (PDU) from a pseudowire emulating a service. The encapsulation is removed from the encapsulated layer-2 PDU and a layer-2 circuit associated with the pseudowire is terminated. The circuit is treated as an interface and the PDU is forwarded based on upper layer protocol information within the PDU.
