Hello,
I am trying to understand the following details about TCP implementation
in FreeBSD (6.1).
- The sack.enable sysctl turns on SACK options (RFC2018)?
Yes. It allows SACK to be negotiated during the SYN/SYN-ACK session
setup.
- Does the implementation leverage SACK information for retransmissions
(RFC3517)?
Yes.
- Is Appropriate Byte Counting (ABC) available (RFC3465) now/in the future?
Not yet but in the future. It is currently being implemented along
with a 'pluggable' congestion control framework for TCP.
