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： 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.
摘要翻译：各种实施例实现一组低开销机制以实现按需路由协议。按需协议在发现洪水期间使用路由累积，以便在更好的路径变得可用时发现，即使协议当前使用的路径没有被破坏。换句话说，机制（或“路由优化”）可以改善路由，即使有功能的路由可用。路由优化机制使得网络中的节点被动地学习路由信息，以便在更改重要时通知需要知道路由信息中的更改的节点。在一些实施例中，在没有任何明确的控制分组交换的情况下，执行在最新路径上学习路由信息并确定将从该信息中受益的节点。路由优化机制之一包括传达描述改进路由的改进路由的信息，其中改进路由从较不接近最优路由发散。

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.
