A method and apparatus for multiple communications sessions is described. In one embodiment of the invention, a computer implemented method comprises establishing a session at a data link layer between a host and a remote access concentrator, determining a set of network layer information corresponding to the session, and applying the set of network layer information to the host at the data link layer.

A method and apparatus for PPPoE multicast is described. A computer implemented method comprises determining a PPPoE client to be multicast capable, determining a layer 2 multicast channel from a layer 3 multicast channel, and transmitting multicast traffic for the layer 2 multicast channel as PPPoE multicast traffic in a PPPoE multicast session to the PPPoE client.

Method and apparatus for PPPoE multicast

A method and apparatus for combining data packets having different protocol encapsulations within a circuit is described. In one embodiment, a method includes receiving a number of Internet Protocol (IP) packets over Ethernet on a real circuit. Each IP packet over Ethernet has an Ethernet header and an IP address. The method also includes removing the Ethernet header from the number of IP packets. Moreover, a number IP packets within a Point-to-Point Protocol (PPP) over Ethernet are received on at least one virtual circuit. Each of the number of IP packets within the PPP over Ethernet includes a PPP header, a PPP over Ethernet (PPPoE) header, an Ethernet header and an IP address. Additionally, the at least one virtual circuit runs within the real circuit. The method also includes removing the PPP header and the PPPoE header from the number of IP packets within the PPP over Ethernet and removing the Ethernet header from the number of IP packets within the PPP over Ethernet. The number of IP packets over Ethernet and the number of IP packets within PPP over Ethernet are forwarded based on the IP address.

A machine readable medium for remote circuit provisioning is described. In one embodiment of the invention, a machine readable medium comprises receiving a packet on a circuit and provisioning the circuit in response to receiving the packet, wherein provisioning the circuit comprises retrieving parameters from a database, creating an empty circuit structure, and populating the empty circuit structure with the parameters.
