Tunable Multicast Protocol
The Tunable Multicast Protocol was developed in the spring
of 1996 in order to produce a reusable tool for the research group to use
for developing MBone Applications that require reliability. The protocol
is a receiver-initiated that performs NACK implosion avoidance using
the slotting and damping techniques from XTP and later used in the SRM
protocol from LBL. We have implemented the protocol using the basic RTP
packet formats and have exploited the control protocols used the RTCP sender and
receiver reports to achieve reliability.
TMP is extremely flexible to the needs of applications including:
- Single Source Ordering or Unordered Delivery
- Total or Partial Buffering for Session Persistance
- Multithreaded recovery of Lost Data
- Token Bucket Flow Control for Data and Control
The protocol is currently implemented for Windows95 and NT.
