Abstract [en]
Despite the continuous developments concerning the performance of the global Internet, and hence networking in general, congestion management remains to be a significant challenge. This is due to the heterogeneity of (1) the infrastructure (wired and wireless), (2) network flows (responsive and unresponsive to congestion), and the enormous growth of users and the variety of services. There are number of solutions proposed to tackle congestion, especially concerning the co-existence of responsive and unresponsive transport protocols. One of those, termed as Combined Model for Congestion Control (CM4CC), in addition to the set of classical congestion control mechanisms employed by TCP, introduced mobile agents to manage the unresponsive flows, such as UDP.
The paper goes beyond the theoretical foundations of CM4CC, established in a few early articles, by using the simulation paradigm to validate the model. In order to do so, various scenarios are implemented in the simulation environment provided by the Optimized Network Engineering Tool (OPNET). The results of the simulation study clearly prove that CM4CC, which is a collaborative effort by TCP feedback mechanisms and mobile agents monitoring and control of the network and in particular the behaviour of UDP sources, is more than a promising venue towards a comprehensive congestion management. Inter alia, the focus is on the extensions made to the OPNET to accommodate mobile agents beyond the multi-tier system, and thus extending the original simulation capacity to the areas such as congestion management, network performance enhancement and stability.
