Message Formats

Binary UDP

Message Layout -- Explanation of message format and the message template
Packet Layout -- the layout of the UDP payload.
Circuits -- Establishment and common operation of UDP circuits between two nodes
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.
Xfer Manager -- messages used by the LLXFerManager class.
Transfer Manager -- messages used by the LLTransferManger class.
All messages -- an alphabetical listing of all messages in the system

Capabilities

The Capabilities system allows viewers to request abilities and be temporarily granted those abilities through a unique URL. The transport format is LLSD XML, and clients can either post new events to CAPS URLs or wait for events to come from the server on the event queue connection the client holds open.

Capabilities use the Linden Lab Structured Data system to represent data. See LLSD.

XML-RPC

Older releases of the official viewer used XML-RPC as part of the Login Protocol. The official viewer now uses a web based authentication protocol, however non-official viewers may still use XML-RPC for login.

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