摘要： Various embodiments implement a set of low overhead mechanisms to enable on-demand routing protocols. The on-demand protocols use route accumulation during discovery floods to discover when better paths have become available even if the paths that the protocols are currently using are not broken. In other words, the mechanisms (or “Route Optimizations”) enable improvements to routes even while functioning routes are available. The Route Optimization mechanisms enable nodes in the network that passively learn routing information to notify nodes that need to know of changes in the routing information when the changes are important. Learning routing information on up-to-date paths and determining nodes that would benefit from the information is performed, in some embodiments, without any explicit control packet exchange. One of the Route Optimization mechanisms includes communicating information describing an improved route from a node where the improved route diverges from a less nearly optimal route.

摘要： Methods and systems for mobility of mobile nodes in mesh networks are taught wherein the mobile mesh nodes choose an attachment point to another mesh node based on predetermined criteria, such as the characteristics of the attachment point's path to a reference destination, and other factors local to the attachment point, such as load and available capacity. The mobile nodes forward packets on each other's behalf. Static and mobile nodes and the links between them are treated differently from each other in view of their respectively different properties. A special metric is used for paths that include mobile links in addition to the static mesh links and wired mesh links. Mobility is handled completely transparently to any client devices attached to the mesh nodes, where this attachment could be wireless or wired.

摘要： Offloading application level communication functions from a host processor. The offloading apparatus can be configured as either a pre-processor or as a co-processor. An interface is provided for receiving a network message sent to the host. An engine performs processing of the network message above OSI level 4. In one embodiment, in a fast-path, a response to the message is sent back to the network without any involvement by the host, providing a complete offload. For other messages, certain pre-processing can be performed, such as parsing of a header, message authentication, and look-up of meta-data. The results of the look-up are then passed to the host with the processed header, simplifying the tasks the host needs to perform. The messages and data are transferred to the host using control and data buffers.
