Hyper-G Client/Server Protocol (HG-CSP)
- Client opens TCP connection on port 418 (by default).
- Protocol format negotiation: binary and ascii forms of
protocol, binary preferred if both can handle it.
- Compression and protocol version negotiation.
- Messages are exchanged (semantics similar to RPC): control
information via port 418, documents through separate channels.
- Documents (e.g. PostScript and VRML files) may also be transmitted in
compressed form, depending on the capabilities of the client.
- Client closes connection (server after timeout).
