Atm0s SDN: Global-scaled Ultra-low latency Decentralized SDN

A SAN I/O driven, open-source decentralized network infrastructure that can deliver high-quality data with minimal latency and efficient cost, similar to what Cloudflare achieves for their network.

For a deep dive into the technical aspects of network architecture, please refer to our Smart-Routing

Features

• Blazingly fast, powered by Rust.
• High availability by being fully distributed, with no central controller.
• Multi-zone support, high scalability.
• Definable Metric based Adaptive routing: cost, latency, .etc...
• Fixed size routing table.
• Designed with large scale built-in PubSub service.
• Automatic Network orchestration and discovery (also can be manual).
• High extendibility by using Network Service.
• Built-in features: PubSub, KeyValue, VPN.
• Cross platform: Linux, MacOs, Windows.

Architecture

Each node in the network is embedded with Geo-Location data inside its ID. A Node ID consists of multiple layers, and every node will have multiple routing tables, each corresponding to a layer.

• Layer1: Geo1 Table (Zone level)
• Layer2: Geo2 Table (Country level)
• Layer3: Inner Geo Group Table (City level)
• Layer4: Inner Group Index Table (DC level)

Getting started

cargo add 8xff-sdn

Create a group chat application (Optional)

You can refer to the chat_example file here to get started on the basis of building an application for the network.

Demo group chat application

Running manual discovery multi nodes in a single device

Start node1:

cargo run --example chat_example -- --node-id 0

Start node2:

cargo run --example chat_example --node-id 1 --neighbour /p2p/0/ip4/127.0.0.1/udp/50000

In node1

> router
[Registry 0] local services: [] remote services: [], nexts []
[Table 0/3/0] slots: []
[Table 0/2/0] slots: []
[Table 0/1/0] slots: []
[Table 0/0/0] slots: [1]
# Join the room using join command with room id
> join 1

In node2

> join 1
> send hello

Now, node1 will receive a message from node2

Node 1 to room 1: hello

Available commands:

• help: Show available commands and description
• router: Print routing table
• join: Join a room
• send: Send a message to room
• leave: Leave joined room

Running manual discovery multi nodes in multi devices

It can also start chat-example in multi nodes and connect over LAN or Internet

Start node1:

cargo run --example chat_example --node-id 0

Start node2:

cargo run --example chat_example --node-id 1 --neighbours /p2p/0/ip4/[IP_HERE]/udp/50000
