基于LAC的LFI支持隧道PPP会话

LAC-based LFI support for tunneled PPP sessions
Abstract:
An embodiment may provide for link fragmentation and interleaving at an access device located between a point to point link and a tunneled connection. An embodiment may include a method of receiving frames through a tunnel from a network server, fragmenting at least some of the frames from the network server, and sending fragmented and unfragmented frames over a data link to an endpoint device. In some embodiments the frames may be multilink point to point protocol (MLPPP) frames. In yet another embodiment, the frames may be received through a layer two tunneling protocol (L2TP) tunnel. An embodiment may include scanning a frame for PPP options and removing options related to MLPPP negotiation and then forwarding the frame to a network server. An embodiment may comprise means capable of executing the embodiment method or may include instructions that when executed on a machine are capable of the embodiment method. An embodiment may include a device with a first port to send or receive fragmented frames to a data link, a second port to tunnel assembled frames to a network server through a packet network, and circuitry in communication with the first port and the second port, the circuitry to fragment link fragmentation frames to be sent through the first port, reassemble any fragmented frames received from the first port, and send or receive assembled frames through the second port.
