TCP Optimization

The Certeon aCelera optimizes TCP transfers so they are more efficient across the WAN. The TCP optimization allows for higher bandwidth utilization in the WAN in both low and bandwidth environments, faster recovery after any packet loss and WAN bandwidth fairness with other flows.

The TCP optimization includes the following features:

• Window Scaling – increases the default 64K TCP window size to ensure efficient throughput in LFNs (Long Fat Networks)
• Slow Start with Congestion Avoidance – Determines available bandwidth and avoids sending more data than network can handle. Avoids network congestion
• Fast Convergence – Rapidly increases throughput of each new TCP connection ensure optimum throughput
• Selective Acknowledgements – Able to precisely determine which packets were lost during transmission so only those need to be retransmitted
