The explosive growth of the Internet has provided modern societies with many new opportunities and challenges. The Internet is greatly reliant on the use of TCP/IP protocol suite. Inevitable delays and congestions over the networks are generally managed using TCP, making it a protocol of significant practical value. However, it is well established that for most large networks its simplistic utilization can result in severe inefficiencies. Alternatively, more sophisticated congestion control mechanisms, such as AQM/RED, are widely employed. But given the complexities of these mechanisms, in many situations, their nonlinear dynamics are usually ignored. As such to avoid instability and oscillatory dynamics, their parameters may be set more conservatively than what is really needed, leading to underutilization of the resources. This preliminary work, reports on a global management scheme and the control laws to expand the stability and operability regions for communication systems and the Internet. In turn, these provide for improved efficiency in utilization of the networks.
