## Packets Specification

Packets structure

![alt text](https://www.gistrec.ru/wp-content/uploads/2019/01/Packets.png)

## Script Specification

1. Sender send `NEW_PACKET` packet to broadcast (or unicast) address

2. Sender send all parts of file via `TRANSFER` packet

3. If any pacckets were lost, receiver ask them sending `RESEND` packet to broadcast (or unicast) address

4. Sender wait `RESEND` packets or wait TTL and turns off

5. Receiver ask all lost parts, until the whole file is no downloaded or wait TTL and turns off
