# SPTP

[![Build Status](https://travis-ci.org/yankeguo/sptp.svg?branch=master)](https://travis-ci.org/yankeguo/sptp)

Simple Payload Transmission Protocol

We assume protocol is handled via internal networking, thus UDP can be considered as a reliable transport.

The only problem is UDP packet size limitation, we solve this by chunk reassembling with unique message id.

## Packet Format

binary format, little-endian

* 1 byte, magic number, `0xAF`

* 1 byte, mode

    * bit 0, 1 = chunked message, 0 = simple message

    * bit 1, 1 = gzipped, 0 = plain

* (for chunked message only), 10 bytes, chunks info

    * 8 byte (uint64), unique message id, random generated

    * 1 byte, total chunk count

    * 1 byte, current chunk index

* n bytes, (segmented) payload
