The increase in network traffic has lead to the concept of congestion in computer networks. The problem of network congestion control remains a major issue in today’s computer networks. Despite various methods and algorithms that has been proposed, however due to the dynamic nature of computer networks, no universal control method has been widely accepted. This paper reviews various conventional methods proposed to avoid network congestion and compares it to computational intelligence (CI) method. A demonstrative simulation is setup to measure congestion in a LAN environment. In addition, the methods of computational intelligence and its efficiency in network congestion management have been addressed in-depth.
