Frame Multicast/Broadcast Library 3/14/00
The Frame broadcast library implements a reliable UDP/IP multicast/broadcast protocol for high speed data transfer over high performance networks such as gigabit ethernet. This API is used to send frame data in near real-time from the data collection units/frame builder to the data monitoring machines at the LIGO observatories. The main features are:
  • UDP/IP multicast or broadcast protocol using propritary packets.
  • Optmized for high speed links and bulk data transfer.
  • Reliable; uses UDP/IP retransmission packets.
  • Quality of service implemented in the receiver.
  • Simple buffer management.
  • One transmitter / any number of receivers.
  • All handshaking hidden from the user; join at any time.
  • No complicated start-up procedures.
