Code propagation and storage.
This file implements a simple form of code propagation, which allows a binary program to be downloaded and propagated throughout a network of devices.
Features:
Commands: load code, start code Point-to-point download over TCP Point-to-multipoint delivery over UDP broadcasts Versioning of code modules
Procedure:
1. Receive code over TCP 2. Send code packets over UDP
When a code packet is deemed to be missed, a NACK is sent. If a NACK is received, the sending restarts at the point in the binary where the NACK pointed to. (This is *not* very efficient, but simple to implement...)
States:
Receiving code header -> receiving code -> sending code
