# Packet
|
|
|
|
A `Packet` is the largest communication object between established `peers`. All communication is done
|
|
via these `packets`. The `packet` itself consists of a fixed size header, and a variable size body.
|
|
The body contains a more specific type of data.
|
|
|
|
## Packet header
|
|
|
|
The packet header has a fixed size of 4 bytes, with the following layout:
|
|
|
|
```
|
|
0 1 2 3
|
|
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

| Version | Type | Reserved |
|
|
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
|
|
```
|
|
|
|
The first byte is used to indicate the version of the protocol. Currently, only version 1 is supported
|
|
(0x01). The next byte is used to indicate the type of the body. `0x00` indicates a data packet, while
|
|
`0x01` indicates a control packet. The remaining 16 bits are currently reserved, and should be set to
|
|
all 0.
