Why to enable RFC-1323? What are the advantages of enabling RFC-1323?
RFC 1323 is a TCP enhancement for improving performance and reliability when transmitting data.
Before RFC-1323, the TCP window size was limited to 64K. This implied that without window scaling, TCP could only send 64k of data before waiting for an ACK. This RFC defines a new TCP option that allows a window size larger than 64K of data before window scaling.
- Enhances the high-bandwidth and long-delay operation of the ProxySG appliances over very high-speed paths, ideal for satellite environments.
- Adds (besides window scaling) RTT calculations that helps with Retransmit TimeOuts (RTO).
- Allows selective ACK with better recovery for dropped packets and Protection Against Wrapped Sequence numbers (PAWS).
NOTE: Some servers or routers don't or are not configured to support TCP extensions for high performance as stated in RFC-1323. This may cause difficulties later on. If you do encounter difficulties when RFC-1323 is enabled on your proxy, please see TECH242703 for some troubleshooting information.
