Recent Triggers of Congestion, Transmission Failures and QoS Degradation in Packet Switched Networks

This study proposes active causes of network congestion, transmission failures and QoS degradation. Communication Networks associate traffic limits. The infinite set of traffic overwhelms the network capacity accompanied by packet loss. Capacity overflows and packet loss create diversified situation such as communication cut off in packet switched networks. Remote linkage of networks are growing hastily. The rapid growth of network architecture has resulted several novel factors that degrade QoS in remote conversation and seriously caused by communication failures. We made an effort to investigate the recent triggers of transmission failures, network errors, http errors, network stress and happening of congestion. The ultimate objective of this study is to find out most prominent sources that activates most critical situations in end-to-end communication. Usually, social networks are more error prone and bandwidth consumer sources. In this study, social, non-social and multimedia servers are examined to predict the share of errors related to http and network layer. We utilized network stress and load testing tool (WAPT6.0) to get practical results about several sort of remote servers in order to predict their effect upon QoS in network communication through particular experimentations.
