  31. TCP Express • Behaviors of a good TCP/IP implementation. • Proper congestion detection. • Good congestion recovery. • High bandwidth utilization. • Being too aggressive can cause individual connections to consume all of the network. • Not being aggressive enough will leave unused bandwidth especially during a low number of connections. • Always needs to adapt to changing congestion. • Increased windowing and buffering will often help compensate for latency and can also offload the application equipment more quickly. • Most important tuning you can do in TCP typically has to do with window sizes and retransmission logic (aka congestion control behavior). • On today’s networks, loss is almost always caused from congestion. • Most TCP stacks are not aggressive enough.

  32. F5’s TCP Congestion Control Algorithms • Reno Congestion Control • Original TCP fast recover algorithm based on BSD Reno. • Initially grows congestion window exponentially during the slow-start period. • After slow-start, increases CWND by 1MSS for each CWND acked (this is linear growth). • When loss or a recovery episode is detected, the CWND is cut in half. • New Reno modifications (this is currently the default mode) • Improves on the Reno behaviour. • When entering a recovery episode, implements a fast retransmit: • Each ACK less than the recovery threshold triggers a one-time resend of the data started by the ACK. • Results in more aggressively sending the missing data and exiting the recovery period. • Scalable TCP (added in 9.4) • Improves on the NewReno behaviour. • Upon loss, the CWND is reduced by only 1/8. • Once out of slow start, CWND increases by 1% of an MSS for each CWND ACK’d. • HighSpeed (F5's proprietary congestion control added in 9.4) • Similarly improves on the NewReno behaviour in combination with Scalable TCP. • Progressively switches from NewReno to Scalable TCP based on the size of the CWND. • Upon loss, the CWND is reduced by somewhere between ½ and 1/8. • CWND grows somewhere between 1% and 100% of an MSS for each CWND ACK’d.

  33. OneConnect ™ – Connection Pooling • Increase server capacity by 30% • Aggregates massive number of client requests into fewer server side connections • Transformations form HTTP 1.0 to 1.1 for Server Connection Consolidation • Maintains Intelligent load balancing to dedicated content servers Good Sources: http://tech.f5.com/home/bigip/solutions/traffic/sol1548.html http://www.f5.com/solutions/archives/whitepapers/httpbigip.html

  35. Content Spooling Problem: TCP Overhead on Servers • There is overhead for breaking apart…”chunking” content • Client and Server negotiate TCP segmentation • Client forces more segmentation that is good for the server • The Servers is burdened with breaking content up into small pieces for good client consumption Solution Slurp up server response Spoon feed clients Benefit: Increases server capacity up to 15%
