<abstract>
<t>
   This memo makes the case for interdependent TCP control blocks, where
   part of the TCP state is shared among similar concurrent connections,
   or across similar connection instances. TCP state includes a
   combination of parameters, such as connection state, current round-
   trip time estimates, congestion control information, and process
   information.  This state is currently maintained on a per-connection
   basis in the TCP control block, but should be shared across
   connections to the same host. The goal is to improve transient
   transport performance, while maintaining backward-compatibility with
   existing implementations.
