TCP-ROME: Performance and Fairness in Parallel Downloads for Web and Real Time Multimedia Streaming Applications

Category: Software and Web Development, Networking and Communications

Overview Parallel download protocols that establish multiple TCP connections to distributed replica servers have the potential to reduce file download time and to improve the quality of realtime multimedia downloads. Unfortunately, parallel download protocols are also inherently unfair towards single-flow downloads. This paper presents TCP-ROME, a parallel download protocol that allows a dynamic mitigation of throughput and fairness. A receiver-based framework allows a dynamic adjustment of the congestion and rate control of each subconnection. TCP-ROME offers two usage modes: a binary mode where the congestion control of each subconnection can be switched between TCP-fair rates (high priority) and at a TCP-LP (low priority) fair rate and a more complex range mode where the aggregated throughput aims at meeting a specified target rate.
