    摘要： A system includes an access node having an associated identifier. The access node is configured to insert the identifier into a network connection request. The system includes an IP edge service node connected to the access node and configured to receive the network connection request. The IP edge service node is further configured to store the inserted identifier and to insert the identifier into an Internet protocol version 6 (IPv6) address request transmitted according to dynamic host configuration protocol version 6 (DHCPv6) through an established network connection based on the network connection request. The system further includes a server configured to receive the IPv6 address request and assign an IPv6 address based on the IPv6 address request.

    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： A method and apparatus for processing a signal on an intermediate network node at an edge of a provider packet-switched network to support a link-layer virtual private network includes receiving a signal on a particular interface. The particular interface is for a direct communication link to a customer network node outside the provider network. It is determined whether the signal indicates that the particular interface is changing from an inactive state to an active state, whereby the signal is called first sign of life (FSOL). If it is determined that the signal is FSOL, then configuration data is determined for configuring the particular interface for the particular virtual private network. The signal is processed based on the configuration data. These techniques allow a dynamic response to new signals on a customer interface without human intervention by the provider.
