TCP Optimization<br />
• Cisco WAAS em<strong>pl</strong>oys TCP optimization to improve ap<strong>pl</strong>ication<br />
throughput and better leverage existing WAN bandwidth capacity<br />
and shield end-nodes from unruly WAN conditions<br />
Bandwidth scalability - help certain ap<strong>pl</strong>ications „fill-the-pipe‟<br />
Connection fairness - ensure bandwidth is allocated fairly amongst flows<br />
Loss mitigation - selective acknowledgement and retransmission<br />
Slow-start mitigation - improve connection setup time<br />
• TCP Proxy architecture provides LAN-like TCP behavior and<br />
provides higher levels of compression than per-packet compression<br />
