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.
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
