A method for use in a first layer-3 switch, the method comprising: learning, by the first layer-3 switch, a first layer-3/layer-2 (L3/L2) cache, the learning of the first L3/L2 cache including generating a first cache entry that maps a layer-3 address of a first device to a layer-2 address of the first device, the first device being part of a first LAN portion; and transmitting, over a wireless network, contents of the first L3/L2 cache to a second layer-3 switch, the transmitted contents including at least a portion of the first cache entry, the second layer-3 switch being part a second LAN portion, the second LAN portion being connected to the first LAN portion via the wireless network.

Method for mobile ad-hoc network (manet) multi-hop routing in a broadcast domain

A fault recoverable computer system including an instruction table having a plurality of processor instructions. The system also includes at least one sensor arranged to monitor an environmental condition and output sensor data. A monitor module is arranged to receive sensor data and/or processor state information. A testing module is arranged to perform a plurality of self-tests including a first self-test of the computer system and, if the first self-test fails, output a failure notification. A recovery module is arranged to update the instruction table in response to receiving the failure notification. The update includes replacing a first processor instruction arranged to perform a first function with a replacement set of processor instructions configured to alternatively perform the first function.

Systems and methods for processor monitoring and recovery

Described embodiments provide systems, methods and apparatus for operating a mobile ad-hoc network (MANET). The MANET includes a plurality of nodes that are identified as stationary nodes or mobile nodes. One or more of the identified stationary nodes are set as backbone nodes. A backbone network is formed by the one or more backbone nodes and an alias is determined for each backbone node. Channel access is allocated to each backbone node based upon the determined alias for the one or more backbone nodes.

Self-configuring backbone for mobile ad-hoc networks (MANETs)

In one aspect, a method to schedule network communications includes transmitting a node identification associated with a first node joining a network over a first portion of control timeslots based on a first probability, detecting nodes in the network using a second portion of the control timeslots and receiving acknowledgments from at least one of the nodes in the network. The method also includes that if a ratio of a number of acknowledgments received to a number of the nodes in the network detected is greater than a predetermined percentage: transmitting control data over the first portion of the control timeslots based on a second probability associated with a number of the nodes detected and transmitting data over the second portion of the control timeslots based on a network schedule.
