KoriNet (Korixa Network Protocol)

A modern alternative for TCP communication—simple, fast, and secure. Designed to structure high-level data exchanges, KoriNet ensures reliability, integrity, and continuity. Lightweight and modular, it adapts to any type of application, from chat and audio to server management, providing developers with a robust and universal protocol.

⚠️ Warning / Usage Limitations

KoriNet is not recommended for public production use. Its current design, which ACKs every message, is optimized for low-latency LANs and stable 24/7 infrastructures. It is intended for internal APIs and fixed applications, not for video, high-latency networks, or heterogeneous clients.

⚠️ Important: At the moment, there is no version coordination, so all clients must run the exact same version of KoriNet to ensure reliability. Future updates will add TLS 1.3 encryption and version management.

Use KoriNet only in environments where stability, low latency, and controlled network conditions are guaranteed.

📦 Installation

KoriNet is available on PyPI.

pip install korinet

Requires Python 3.11+.

🔌 Connection resilience & reconnection handling

The following console capture illustrates how KoriNet behaves during a connection loss between a client and a server.

(1) Client-side behavior

The client automatically detects the connection failure and continuously attempts to reconnect by creating new TCP sockets. This demonstrates KoriNet’s ability to recover from transient network errors without manual intervention.

(2) Connection interruption

The disconnection is intentionally triggered using a KeyboardInterrupt on the server side. This simulates a real-world network failure (service crash, link loss, or network interruption) and produces the same behavior as an actual outage.

This example highlights KoriNet’s usefulness for long-running services (24/7), internal APIs, and stable infrastructures, where automatic reconnection and communication continuity are critical.

☁️ Server

import time
import traceback
from korinet import server

# SOCKET
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
sock.bind(("127.0.0.1", 1235))
sock.listen(10)
sock.settimeout(5)
try:
    while True:
        try:
            conn, addr = sock.accept()
            client = server(conn)
            while True:
                print(client.recv(giveID=True))
                client.send({"status": True})
                time.sleep(1)
        except Exception as e:
            print(traceback.format_exc())
            print(e)
except Exception as e:
    print(traceback.format_exc())
    print(e)

👤 Client

from korinet import client
C = client("127.0.0.1", 1235, timeout=4)
num = 0
while True:
    C.send({"type": "ping", "num": num})
    print(C.recv())
    num += 1
    time.sleep(1)

🔧 RAW Protocol (Low-level usage)

from korinet import protocol

session = protocol.v2(sock)  # raw TCP socket required
session.send({"type": "ping"})

response = session.recv()
if response["status"] is not True:
    raise RuntimeError("Invalid response")

KoriNet exposes a raw protocol layer (protocol.v2) that can be used directly on top of an existing TCP socket, without the high-level client / server abstractions.

This mode is intended for advanced users who want:

• full control over the socket lifecycle
• minimal overhead
• a simple framed message protocol (block-based send/recv)

⚠️ Important limitations

When using the RAW protocol:

• ❌ No automatic reconnection
• ❌ No session continuity
• ❌ No metadata for recovery
• ❌ No compatibility with client / server

If the underlying TCP socket is closed or lost, the session is definitively broken. You are fully responsible for:

• detecting disconnections
• recreating sockets
• restoring application state

This behavior is equivalent to a classic TCP protocol without resilience.

---

🔌 When should you use RAW protocol?

Use protocol.v2 only if:

• you do not need reconnection
• your application tolerates socket loss
• you want a thin, structured framing layer on top of TCP
• you manage network failures yourself

Typical use cases:

• short-lived connections
• internal tools
• experimental protocols
• controlled environments

If you need 24/7 stability, automatic reconnection, or network fault tolerance, use the high-level client / server API instead.

---

➡️ In this mode, KoriNet only guarantees message framing, not connection recovery.

---

🧠 Design note

The RAW protocol is the foundation layer used internally by:

• client
• server

Those high-level components add:

• reconnection logic
• session metadata
• continuity guarantees

Using protocol.v2 bypasses all of this by design.
