Re: [re-ECN] implementations

BT has produced an implementation on Linux. It has specifically been
built on kernel version 2.6.27.7, but would work on any version where
the patched files are not altered from this version. 

It has a simplified version of byte accounting i.e it attempts to
forward mark packets to an equivalent number of bytes to those that have
been congestion marked. It does this by keeping a record of the largest
segment transmitted and assuming that feedback of a congestion mark
relates to the largest packet transmitted so far. This is a conservative
approach, ensuring that the implementation does not under report
expected congestion.

Re-ECN interworking with ECN (Re-ECN co-mode) has also been implemented.

Availability is via email to me.

Hi,

Following up an off-list suggestion -- we've heard passing references to

re-ecn implementations, but it would probably be good to be able to be a

bit more authoritative.

If you've done such implementation work -- I'm happy to collect 
references here and at least have a slide up in Hiroshima to list 
them/provide further pointers for people.

Thanks,
Leslie.
