WATM11 — Issue/Telecom Wireless CORBA: Retransmissions in UTP

  • Key: WATM11-2
  • Legacy Issue Number: 7610
  • Status: closed  
  • Source: Nokia ( Kimmo Raatikainen)
  • Summary:

    The section 7.4 'UDP Tunneling' does not say anything about retransmissions. This may lead to implementations that are either suboptimal in bandwidth consumption or incompatible.

    Give recommendations about retransmission policy similar to TCP's NewReno-SACK.

    Revised text:

    Add a new subsection 'Retransmission Policy' before the subsection 7.4.2 'Fragmentation':

    Retransmissions in UDP Tunneling Protocol SHOULD be controled by a policy based on an estimate for the Round Trip Time (RTT) such as NewReno-SACK in TCP [RFC nnnn]. The Retransmission TimeOut (RTO) MUST be at least the estimated RTT.

    Add the following note at the end of subsection 7.4.6 'Resume':

    Note: The Resume chunk SHOULD be included in each UTP message until the sender has received an acknowledgement for a message containing a Resume chunk.
