Protocol
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
LLXFerManagerclass. - Transfer Manager -- messages used by the
LLTransferMangerclass.
Communication with userserver
- Userserver Agent -- agent update information which alters userserver state.
- Userserver Relay -- messages relayed between the back-end systems and the viewer.
Communication with simulator
- Agent Messages -- agent movement, animation, appearance, etc.
- Inventory Messages -- agent inventory and asset management.
- Money Messages -- money queries and updates.
