3.2.4.5.6.1 Virtual Connection Cookie Found

  • Article

If the virtual connection cookie is found in the virtual connection cookie table, an implementation of this protocol MUST execute these steps:

  1. Conform the outbound proxy to the OUT_R2 protocol sequence.

  2. Initialize an instance of the Outbound Proxy OUT Channel and set the Non Default Outbound Channel Reference of the Outbound Proxy Virtual Connection, which is considered the successor channel.

  3. Set the Non Default OUT Channel Cookie in the Outbound Proxy Virtual Connection to the value of SuccessorChannelCookie in the OUT_R2/A3 RTS PDU.

  4. Compare the PredecessorChannelCookie in the OUT_R2/A3 PDU to the Default OUT Channel Cookie in the Outbound Proxy Virtual Connection. If they do not match, the outbound proxy MUST treat this PDU as a protocol error as specified in section 3.2.4.5.14.

  5. Set the value of PeerReceiveWIndow in the outbound proxy OUT Channel to the value of OutboundProxyReceiveWindowSize in the OUT R2/A3 RTS PDU.

  6. Send OUT_R2/A4 RTS PDU to the server.

  7. Switch the successor OUT channel instance to plugged channel mode.

  8. Transition the state machine to state B1OrC1W.
