Guaranteeing QoS in a Crises Response Network

Abstract: Main task in this thesis is to see how different queuing techniques can be used to provideguarantee QOS (message precedence) in crises response network. There are different types oftraffic on communication links e.g. voice, video and elastic data. If the network is not properlydesigned, traffics will chop all the bandwidth of the link and the link would be congested, inemergency situation prioritized call will get prioritized over general traffic. Sometimesemergency situation occur in these situations emergency calls will get prioritized. In these cases,prioritization queuing methods must be applied in order to secure emergency communication andto assign it the highest priority.The evaluation is conduct in a laboratory environment, where a network is set up with equipmentlike 3600 and 2800 series CISCO routers, 3800 series CISCO switches, with some real clientsand Cisco IP communicators.
