3.2.3.5.5.1 Virtual Connection Cookie Found

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

  1. Inbound proxy MUST conform to IN_R2 protocol sequence.

  2. The virtual IN channel that belongs to the virtual connection found in the virtual connection cookie table is verified to be in opened state. If the verification fails, it is a protocol error and MUST be treated as a protocol error as specified in section 3.2.3.5.10. If the verification succeeds, the IN channel instance MUST be set as a nondefault IN channel and a component of the virtual IN channel found through the virtual connection cookie table. In terms of virtual IN channel state machine, this message MUST effect a transition as an IN_R2/A1 event from the opened state to the Opened_A5W state.

  3. The successor IN channel from client to inbound proxy is switched to plugged channel mode.

  4. The server MUST compare the value of PredecessorChannelCookie in the IN R2/A1 PDU to the value of the DefaultInChannelCookie from the inbound proxy Virtual Connection. If they do not match, the server MUST treat it as a protocol error as specified in section 3.2.3.5.10.

  5. Set the value of the DefaultInChannelCookie in the inbound proxy Virtual Connection to the value of SuccessorChannelCookie from the IN R2/A1 PDU.

  6. Wait for further network events.
