- TFRC Veno: An Enhancement of TCP Friendly Rate Control Over Wired/Wireless Networks
- TFRC is a TCP-Friendly Rate Control protocol based on TCP Reno's throughput equation. It is designed to provide optimal service for unicast multimedia flow operating in the wired Internet environment. However, in wireless networks, TFRC, same as TCP Reno, suffers significant performance degradation. This paper proposes to make use of...

- TCP-Friendly Rate Control With Token Bucket for VoIP Congestion Control
- TCP Friendly Rate Control TFRC is a congestion control algorithm that provides a smooth transmission rate for real-time network applications. TFRC refrains from halving the sending rate on every packet drop; instead it is adjusted as a function of the loss rate during a single round trip time. TFRC has...

- Improving TCP Friendly Rate Control Behaviour in DVB Satellite Networks
- This paper envision in the not so distant future an Internet where the biggest share of bandwidth is used by streaming applications, without any hard reservations in the network core. Such a traffic distribution calls for a robust end-to-end congestion control mechanism, eventually forced by access networks, so that the...

- Performance Analysis of TFRC Over Wireless Link With Truncated Link-Level ARQ
- In this paper, an analytical framework is proposed for evaluating the Quality of Service QoS of TCP-Friendly Rate Control protocol TFRC in hybrid wireless/wired networks. For the wireless network, a link-level truncated Automatic Repeat reQuest ARQ scheme is deployed to reduce the packet losses visible to the transport layer protocol....

- Efficient Data Transport in Wireless Overlay Networks
- Performance evaluation of GPRS is an active research area. TCP performance, buffering, scheduling, and quality of service were studied through analytical analysis and simulation. The study describes excessive buffering in the GPRS network that results in unfair sharing of bandwidth between several TCP flows. The paper presents a transparent proxy...

- TCP-Friendly Many-to-Many End-to-End Congestion Control
- The paper addresses the issue of TCP-friendly congestion control mechanism for many-to-many communication environment. Lack of congestion control inhibits deployment of WAN applications that involve collaboration of groups of processes in the Internet environment. Recent efforts targeted unicast WAN congestion control TFRC. The paper extends that approach to multicast many-to-many...
