In high bandwidth and low latency data center networks, when multiple data senders simultaneously communicate with a single receiver, namely in many-to-one communication pattern, it is frequently occurred that the burst data overload the receiver's switch buffers, which leads to TCP throughput collapse. This phenomenon is termed to TCP Incast problem, which has become a new hot research topic in recent...
In order to solve the problem of transporting e-VLBI data in fast long distance networks, a new TCP algorithm is proposed in this paper. This new algorithm directly relays on the application layer to adjust its congestion window (cwnd) and transfer rate, so we named it ABCTCP (Application Based rate Controllable TCP). To reach the desired throughput, ABCTCP increases its cwnd aggressively without...
Wireless stations (WSs) in an IEEE 802.11 access network compete with each other for collective bandwidth offered by access points (APs). The competition involves selecting an AP with the consideration of potential link rate and workload status. From the perspective of system, a good AP selection policy should be stable, increase overall system throughput, and maintain bandwidth fairness among WSs...
WiMAX technology is a good candidate to provide broadcast TV services for mobile users because it supports QoS based multicasting functionality. To provide multicast-based TV services over the mobile WiMAX network, a multicast session setup involves both MAC-layer and IP-layer multicast management. However, in mobile environment, IP-layer multicast management entails service interruption due to unreliable...
