摘要： One embodiment includes, inter alia, methods, apparatus, computer-storage media, mechanisms, and/or means associated with automated transitioning between different communication protocols in a network. In one embodiment, automatic transition routers are automatically discovered along with the knowledge of what non-native protocols need to be transported across a network. Communication pathways are automatically established as needed to transport these non-native protocols. One embodiment is particularly useful in transitioning a network from one protocol to another, such as from Internet Protocol version 4 to version 6.

摘要： A method is provided in one example and includes receiving signaling data associated with a request for a multicast channel, the request includes an Internet protocol version 6 (IPv6) source and an IPv6 group address. The method may also include identifying an Internet protocol version 4 (IPv4) source and an IPv4 group address to be mapped to the IPv6 source and the IPv6 group address. The signaling data can be converted from a first protocol to a second protocol. The converted signaling data can be communicated to a network element. In more particular embodiments, the network element is an IP edge router configured to join the multicast channel and stream data in response to receiving the converted signaling data. The IP edge router can be configured to perform an encapsulation operation to transport IPv6 multicast packets within an IPv4 multicast channel.

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： In one embodiment, for each port of an access node in an access-based computer network, one access server of a plurality of access servers is configured as a preferred access server for that port. Upon receiving a session initiation message at a particular port, the access node forwards the session initiation message to one or more of the access servers based on the configured preferred access server for the particular port.
