V- Accel

1. V-Accel File Transfer Acceleration Technology V-Accel: File Transfer Acceleration Solution

2. What could be the reason? Will Increasing bandwidth help? But we can see that the existing bandwidth is not fully utilized ! Does other protocol help? FTP ?? HTTP ?? CIFS ?? Oops ,Nothing Helps !!! Feeling Like THIS !!! • Why sending files ( like MPEG video file or any other file)take ages, even over 45Mbps ??? Patent pending technology of Viaedge V-Accel can help you  V-Accel: File Transfer Acceleration Solution

3. TCP – The Culprit • Flow Control • TCP Buffer, Sender requires for packet retransmission and Receiver requires for ordering out-of-sequence packets. • BDP establishes minimum TCP window size reqd. (under ideal conditions). • 1Mbps  600 msec RTT ~ 77KB Buffer. • 16 KB Buffer  600 msec RTT ~ 213kbps. • Congestion Control • Works in two phases, Slow Start & Congestion Avoidance. • Slow Start phase occurs at beginning of a connection / after Retransmission Time-Out. • Congestion avoidance phase occurs after packet loss. • Impact in environment having high bit-rate error & RTT. • Loss events results in reduced transmission rate. • Slow Start terminates prematurely, longer time required to reach Maximum throughput. • Perspective • 1Mbps  6K Buffer  50 msec RTT  4 Round Trip  200 msec. • 1Mbps  77K Buffer  600 msec RTT  10 Round Trip  6000 msec. • Perspective (Error Recovery) • 1Mbps  6K Buffer  50 msec RTT  4 Congestion Window Increase  200 msec. • 1Mbps  77K Buffer  600 msec RTT  25 Congestion Window Increase  15000 msec.
