Dynamic capacity migration between circuit and packet networks is an unexplored topic, but it can be an effective way to improve network utilization. We discuss techniques for dynamic capacity sharing between circuit and packet services.
The active queue management in Internet routers exploits the idea that an incoming packet can be dropped by the router even if there is some available buffering space in the router. Therefore, the router can send congestion signals to TCP before the actual congestion occurs, preventing queues and delays from growing too high. Many active queue management algorithms has been proposed till now. Unfortunately,...
Overlay applications are generating most of the traffic in today's Internet. Therefore, the impact of the increasing P2P traffic on ISP's Capital and Operational Expenditures (CAPEX/OPEX) is one of its major concerns. In this paper, an overview of ISP methods for P2P traffic management is provided. The ISP has to consider the optimization of this traffic and its associated operational costs. Therefore,...
Queue length oscillation at a congested link causes many undesirable properties such as large delay jitter, underutilization of the link and packet drops in burst. The main reason of this oscillation is that most queue management schemes determine the drop probability based on the current traffic without consideration on the impact of that drop probability on the future traffic. In this paper, we...
