Issues Descriptions

SequenceNumberSet validity could be too strict

  • Status: open  
  • Source: Object Computing, Inc. - OCI ( Mr. Adam Mitz)
  • Summary: SequenceNumberSet defines one of the rules for validity as
    bitmapBase >= 1

    We have observed that other implementations use bitmapBase 0 in AckNack submessages. There seems to be no downside to just accepting these as valid even though the spec currently says they are not.

    The RTF should determine if this condition in can just be removed.

Support transport-level RTPS message compression

  • Status: open  
  • Source: Real-Time Innovations ( Dr. Gerardo Pardo-Castellote, Ph.D.)
  • Summary:

    Some transports have limited bandwidth and may benefit from compressing the RTPS message prior to being sent over the transport.

    This is something that could be added in a reasonably simple manner by considering this part of the transport PSM.
