T/TCP: Transaction Oriented TCP

• Three-way handshake ? Long delays for transaction-oriented applications.

  • T/TCP extension avoids 3-way handshakes
  • Request/reply data sent with connection messages
  • Server caches a connection count (CC) per-client to detect duplicate requests and avoid replaying transaction
  • TIME_WAIT is shortened by setting it to 8*RTO
  • Latency = RTT + server processing time (SPT)
