In order to spot potential trouble spots, we want to have a pretty clear understanding of the UDP, TCP, and by-product communication between the client and the servers.

The UDP Message System

  • Packet Layout -- the layout of the UDP payload.
  • Packet Accounting -- how the message system handles packet sequencing, reliability, suppression, throttling, etc.
  • Common Messages -- messages that are handled by every indra message system instance. (All messages handled in llmessage/message.cpp)
  • Xfer Manager -- messages used by the LLXFerManager class.
  • Transfer Manager -- messages used by the LLTransferManger class.
