3.2.4.5.6 OUT_R1/A3 or OUT_R2/A3 RTS PDUs

  • Article

The OUT_R1/A3 RTS PDU and the OUT_R2/A3 RTS PDU have the same format, and the outbound proxy determines which RTS PDU it received based on internal state as defined in this section.

An outbound proxy implementation MUST NOT accept either of these RTS PDUs in any state other than Open_Start. If they are received in any other state, the outbound proxy MUST treat these PDUs as a protocol error as specified in section 3.2.4.5.14.

If either of these RTS PDUs is received in the Open_Start state, the outbound proxy implementation MUST retrieve the virtual connection cookie from the OUT_R1/A3 RTS PDU and search for a matching cookie in the virtual connection cookie table. If found, it MUST execute the sequence of steps specified in section 3.2.4.5.6.1. If not found, it MUST execute the sequence of steps specified in section 3.2.4.5.6.2.
