  • Session redundancy using a replay model
    Patent number: 8677169
    Abstract: A mechanism for synchronizing states of components in a first routing engine to corresponding components in a second routing engine is provided. In order to reduce the amount of data required to synchronize the state of the components and the time and resources required to perform the synchronization, the state-related information transmitted from the first routing engine to the second routing engine is limited to information used to build states of a subset of the components associated with the first routing engine. That subset of components is limited to those components that receive stimuli (e.g., data streams or data packets) from sources external to the routing engine. Other components on the second routing engine synchronize state by receiving information from those components on the second routing engine that received the external stimuli information.

  • Access device-based fragmentation and interleaving support for tunneled communication sessions
    Patent number: 7761508
    Abstract: 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.
