Abstract

See full text

Link fragmentation and interleaving at an access device located between a point to point link and a tunneled connection is provided. A method of access device-based link fragmentation and interleaving is also provided. The method includes 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. The frames may be multilink point to point protocol (MLPPP) frames and the frames may be received through a layer two tunneling protocol (L2TP) tunnel. The method can include scanning a frame for PPP options and removing options related to MLPPP negotiation and then forwarding the frame to a network server.
