A mechanism for controlling incoming Internet Traffic into Multi service Networks

Controlling of incoming internet traffic is very challenging in today’s computer networks because network administrators have limited control over incoming traffic. Prioritizing incoming traffic in public institutions such as universities is challenging as students often tend to misuse internet by initiating a lot of traffic with non-academic interaction including downloading entertainment materials such as movies amidst limited bandwidth for those focused on research. The Explicit Congestion Notification mechanism enables the Universities’ network administrators to control incoming internet traffic without help from the Internet Service Provider (ISP) as well as installing special devices on the network. The low priority traffic is controlled before leaving the sender by tricking the sender to think that the network is congested by using Explicit Congestion Notification (ECN) signal and adjusting the congestion window size of the low priority traffic. This will free bandwidth for high priority traffic needs such as research. This mechanism has proven efficient in securing and making available 80% of the total bandwidth for high priority traffic.
