  • United States Patent 20060029074, "Enhanced Multicast Forwarding Cache (eMFC)" Abstract: An Enhanced Multicast Forwarding Cache (eMFC) supports multicast transmissions in mobile mesh networks. The enhanced MFC is designed to support mesh node mobility, quality of service, and security requirements that are particular to mesh networks. To achieve these goals, the enhanced MFC draws from a global state maintained by a unicast routing protocol, multicast aware applications, and distributed services. The eMFC distributes this derived global state through the use of an eMFC-specific multicast packet header. Information contained within the eMFC header is also used to collect and derive multicast traffic statistics at each mesh node. To maintain backwards compatibility, multicast traffic without the eMFC-specific header is also honored by the MFC. Mobile mesh network specific interfaces, such as radio interfaces, as well as conventional interface types are supported. Security is maintained through the use of authentication and encryption techniques.
  • United States Patent 20070140129, "Ad-Hoc Network Routing Metric Optimization" Abstract: A network processing device calculates variable link metrics and then prioritizes selection of network links for sending packets according to the calculated variable link metrics. The variable link metrics can include a link capacity index that represents a combination of platform and interface capabilities for nodes on opposite ends of the network links. The link metrics can also include an expected retransmission value that indicates the percentage of packets that may have to be transmitted over different links.
  • United States Patent 20070140239, "Distributed Services For Mesh Networks" Abstract: Nodes in a mesh network are configured to access centralized Internet Protocol (IP) services whenever the Internet infrastructure is accessible and then dynamically switch to providing the IP services locally in the mesh network when the Internet infrastructure is not accessible and operate through collaborative cooperation. In one embodiment, a Reported Node Time Server (RNTS) is elected when the mesh network is disconnected. In another embodiment, a Mesh Network Name Cache (MNNC) protocol pre-provisions each mesh node with the names and addresses of all other mesh nodes. In another embodiment, a Mesh Address Allocation Protocol (MAAP) provides DHCP services for DHCP clients in the mesh network.
