Packets format

Packets are tarball files with .packet suffix.

On logic level, every packet consists of:

  • one header, a dictionary of key-value pairs;
  • records, a dictionary of key-value pairs and optional data depending on record type.

Header

Header is being stored in JSON notation in /header file in packet tarball.

  • src, sender's GUID
  • dst, optional destination GUID
  • filename, suggested file name for packet file, it is assumed to be unique

Record types

  • sn_push:
  • cmd: sn_push
  • src: sender's identity to push from
  • [dst]: receiver's identity to push to, optional for packets from master
  • sequence: Sequence associated with packet's payload
  • ACK packet:
  • type: ack
  • src: master's identity
  • dst: receiver's identity ack is intended for
  • push_sequence: original PUSH packet's sequence
  • pull_sequence: Sequence after merging original PUSH packet
  • PULL packet:
  • type: pull
  • src: sender's identity to pull to
  • dst: receiver's identity to pull from
  • sequence: Sequence to pull for
