TCP IP connection

General info:

To make it possible to publish messages with Blazing Fast performance, a TCP/IP connection is introduced.

The Basic Packet Structure is:

• u8: PacketType
• payload: payload - according to the packet_type;

Packets:

PING=0

• Direction: From Client to Server
• Payload is empty

PONG=1

• Direction: From Server to Client
• Payload is empty

GREETING=2

• Direction: From Client to Server

• Payload structure:

  • Name: PascalString - of Name of the application which is making a connection. MyServiceBus Library version is inside this Feel; Ex: MyApp;1.0.0
  • ProtocolVersion: i32 - Global Version of the Client. Not Used yet. Reserved...

PACKET_VERSIONS=11

Each Packet by default has a version=1. If we are doing a breaking change of the payload - we increase the version of the packet. This packet is sent first one after the connection is established

• Direction: From Client to Server
• Payload structure
  • Len: u8 - the number of packets we are upgrading versions:
  • Len times sequence of
    • packetId: u8;
    • packetVersion: i32
