TODOs and notes on networking

Idea: arbitrary model support through observables (a framework for simulation state sync?)

Synchronization model

https://github.com/rygorous/gaffer_net/blob/master/main.cpp

Target bandwidth range vs Actual bandwidth use

• separate sync mechanisms for separate properties
• prioritization of sync for different properties
• adaptive sync methodology
• express changing values as rate of change for interp
• trans Simuation migration of objects
• support simulation-level persistence (binary file, and maybe redis?)
• property bounding (limit range, define quantization)
• custom property serialization traits (e.g. quaternion's 'smallest three')
• delta compression - send only what has changed
• arbitrary precision types (like varint)
• desync handling

Knobs:

• snapshot send rate (per second)
• packet size
• interpolation between snapshots in buffer
• size of snapshot buffer
• extrapolation of velocities, linear and angular
• protocol (tcp/udp) - udp send/ack_send
• data compression (none, zlib, compress)
