By separating different message types onto dedicated communication channels, Kaia can maintain efficient block propagation and consensus even under heavy network congestion. + +### Architecture + +![Multi-Channel Server](/img/learn/multichannel.png) + +_Multi-Channel Connection_ + +![Single Channel Server](/img/learn/singlechannel.png) + +_Single-Channel Connection_ + +### Configuration Modes + +- **Multi-Channel:** Uses two ports. Enabled by default in `kend` due to `MULTICHANNEL=1` in `kend.conf`. Disable by setting `MULTICHANNEL=0`. Customize ports using `--port` and `--subport` flags. +- **Single-Channel:** Uses one port (default 32323). Active when `MULTICHANNEL` is not set or set to `0`. + +### How Multi-Channel Works + +Multi-channel separates different message types onto dedicated ports: + +- **Main Port:** Handles block-related messages (requests/responses for hash, header, body, receipt) and consensus messages (Request, Preprepare, Prepare, Commit, RoundChange). The meaning of the messages can be found in [PBFT](./consensus-mechanism.md#pbft-practical-byzantine-fault-tolerance). +- **Subport:** Handles transaction messages. + +This separation enhances network stability: if one port fails, the other continues operating. For example, if the subport (typically congested during high traffic) fails, the main port maintains essential block and consensus operations. + +### Connection Establishment + +- **Multi-Channel to Multi-Channel:** Both ports are used. +- **Other Cases (Multi-Channel to Single-Channel or Single-Channel to Single-Channel):** A single port is used. + +If a node attempts to connect without specifying a subport, it initially connects using a single port. During the handshake, if the peer is multi-channel, the connection is re-established using both ports. + +### Port Configuration (KNI) + +See [the KNI scheme](./kni.md) for details. Default ports are 32323 (main) and 32324 (sub). + +### Integration with KNI + +Multi-channel integrates with KNI for node discovery and connection. KNI URLs allow specifying both main and subports. + +### Implementation Note + +Kaia's multi-channel implementation deviates slightly from the original specification. While the details of this deviation are beyond the scope of this document, the core principles of enhanced network communication and robustness remain central to Kaia's operation. This information is primarily relevant for node operators and developers. + +In summary, multi-channel enhances Kaia's network by segregating message traffic, improving efficiency and resilience. While providing advanced configuration options for node operators, the system remains transparent to general users.
