With the development of Mobile IPv6 and multicast technology, mobile multicast becomes a research hotspot. Based on two basic mobile multicast methods, the Bi-directional Tunnel (BT) method and the Remote Subscription (RS) method, some mobile multicast schemes have been proposed. However, most of them evaluate the performance by means of analysis and simulation, but lack of testing the performance...
This paper makes use of the fluid-based approach to model the throughput of TCP Veno flow over wired/wireless networks. A generalized formula is derived between Veno's throughput and its window evolution parameters, packet loss rate and round-trip time. Simulation experiments and real network measurements are conducted to validate the accuracy of this model.
This paper aims to study the queue dynamics of TCP Veno with RED in the wired-wireless heterogeneous networks. The authors first develop a fluid-flow model of TCP Veno with RED over heterogeneous network, and then use the classical linear feedback control theory to analyze it. Analysis results reveal the relationship between the RED queue oscillation and the network parameters. The authors use simulation...
TCP Veno was recently proposed to eliminate TCP performance suffering in the wireless networks. Real network and live Internet measurements have validated Veno's significant performance improvement over Reno. In this paper, we revisit Veno's state distinguishing scheme, and give a detailed study of Veno's performance when three different recovery schemes: Partial ACK, SACK and PACK, are incorporated...
In this paper, we aim to study TCP Veno's loss distinguishing accuracy in different network conditions and its performance influence. We first propose a heuristic formula. Based on the simple math analysis and experiment results, we show the sensitivity of Veno's loss distinguishing accuracy on network parameters. Thereafter, we demonstrate two cases to study its performance influence. One case is...
In this paper, we develop a fluid-flow model of TCP Veno with RED queue management, and use this model to analyze its equilibrium state stability and throughput. On the stability side, our model reveals the relationship between Veno AIMD parameters and system stability region. On the throughput side, our model derives a closed-form throughput formula for bulk transfer TCP Veno flow. We found that,...
One sender-side TCP enhancement, called TCP Veno, was recently proposed to mainly eliminate TCP performance suffering in the wireless environments. Although TCP Veno shows remarkable performance improvement over legacy TCP, namely TCP Reno, Veno has not been utilized at its full potential. In this paper, we study the enhancement of TCP Veno with FACK (forward acknowledgement), called TCP Veno-F. The...
