IP Queuing Analysis

There is a huge demand for the Internet as the number of services keeps increasing. One common service is database transaction processing. Currently most confidential information is maintained in a database, and whenever users want to access the information, the information is retrieved from the database over the network. In order to complete this transaction process successfully the network should maintain a good QoS ( Quality of Service) to provide satisfactory results to the user. QoS must be efficient to differentiate the traffic and satisfy their specific requirements. The router allots some resources and queuing techniques govern how packets are buffered while waiting to be transmitted or processed. There are various queuing disciplines that can be used to transmit packets, and the two queuing techniques discussed in this paper are WeightedFactor-Queuing (WFQ) and First-In-First-Out (FIFO). The simulation model consists of heavy database traffic flowing through the network’s bottleneck link.
