- Utilize TrySend to properly backpressure network traffic
- Split updates into reasonable sized frames using WS fragmentation
- Use WS pings for network aliveness (requires 4.1 protocol revision)
- Measure RTT only at start of connection, rather than periodically
(this avoids them being affected by other network traffic)
- Refactor network queue
- Refactor network ping, ping from server as well
- Improve meta topic performance
- Implement unified approach for network value updates (currently client and server use very different approaches) that respects requested subscriber update frequency
This adds a new protocol version (4.1) due to WS bugs in prior versions.
Currently, the server rejects duplicate client IDs. As we want to make
the client implementation as simple as possible, instead deduplicate the
name on the server side by appending "@" and a count.
NT4 spec has been updated for this change.
