From 27852c26baab8b95fc9a2b3e8a18770ecd553f10 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Thu, 2 Feb 2006 16:57:31 -0800 Subject: [SCTP]: Fix 'fast retransmit' to send a TSN only once. SCTP used to "fast retransmit" a TSN every time we hit the number of missing reports for the TSN. However the Implementers Guide specifies that we should only "fast retransmit" a given TSN once. Subsequent retransmits should be timeouts only. Also change the number of missing reports to 3 as per the latest IG(similar to TCP).
