Wireless Networks for Disaster Control and Bandwidth Augmentation

"This is a proposal to develop the software needed to provide backup wireless connectivity for a damaged shipboard network. In addition to controlling the wireless link, the software must also reconstitute the network and perform triage of the packetspassing through it.The wireless link scavenges bandwidth wherever it can be found; there are no guaranteed link statistics. The performance has to be measured and then the routes recalculated. An optimum network routes by the message's type of service. Metric Systemsproposes to reinsert type of service routing into OSPF and to add separate arithmetics for each type of service, so that costs such as reliability can be used.The wireless link will allow messages to flow through the network, but not at the same rate as on the undamaged network. Under these circumstances, it is necessary that a "vital" message have delivery precedence over an "important" message. IP has setaside three bits in the packet header to contain "Precedence." The meaning of these bits and the rules for interpreting them and forwarding them is undefined. Metric Systems proposes to establish the meaning and rules for these bits and modify a Linuxkernel to observe the rules.The wireless link scavenges bandwidth wherever it can be found; there are no guaranteed link statistics.
