Overview

Chamomile

Build a robust stable connection on p2p network

features

Support build a robust stable connection between two peers on the p2p network.
Support permissionless network.
Support permissioned network (distributed network).
DHT-based & Relay connection.
Diff transports: QUIC(default) / TCP / UDP-Based Special Protocol.
Multiple transports connecting at same runtime.

Simple test.

A: cargo run --example permissionless 127.0.0.1:8000
B: cargo run --example permissionless 127.0.0.1:8001 127.0.0.1:8000
C: cargo run --example permissionless 127.0.0.1:8002 127.0.0.1:8000

If not support 127.0.0.1 binding, you can change to 0.0.0.0 and try again.

Relay test.

A: cargo run --example relay 192.168.xx.xx:8000
- this ip is your LAN address, it will do relay work.
B: cargo run --example relay 127.0.0.1:8001 192.168.xx.xx:8000
- start waiting stable connected by relay.
C: cargo run --example relay 127.0.0.1:8002 192.168.xx.xx:8000 XX..
- XX.. is above's B network peer id will connected it.
- And if change B and C 127.0.0.1 to 0.0.0.0, they will automatically connect after the handshake is successful, no longer need relay.

Design point

Mobile phones, IoT devices, PC and servers are first-class citizens
Ability to adapt to the transmission and penetration of complex network environments
Support for springboard function, virtual connection with other nodes, build virtual DHT
Encrypted transmission and secure DHT protection
It can support all interconnections and single-center connections under the LAN, and can also support DHT in the public network environment
Automatically switch the connection according to the number of connections and the network environment
If Alice use QUIC, Bob use TCP, they can still connect and communicate with each other.

[Question] Protocol and Transport Characteristics
I've got a couple of general questions about the chamomile protocol and transports:

What are the requirements for a chamomile transport implementation at the message level. Does it need to make sure that messages are delivered reliably and in-order like TCP or can messages be unordered and unreliably delivered like UDP?

Is the protocol suitable for streaming applications such as network gaming or video conferencing or is it not designed for high-bandwidth, low-latency communication and it would instead be used to find peers and establish a different protocol connection between peers for things like streaming video?

RFC: QUIC-like UDP transport.

What ?

QUIC-like UDP without it's cryptography, because we has our cryptogrpahy protocol.

Why ?

we need a udp transport, because many connection will incoming, so tcp socket has limit number, it is better to use UDP.

How ?

RFC: support multiple transports at same runtime.

When peers use different transport, and want to connect, the sender must use the receiver's default transport. Example: Alice use tcp as default, Bob use quic as default.

When Alice wants to connect to Bob, she needs to start a quic connect to Bob, and then they use this quic connection. When Bob wants to connect to Alice, he needs to start a tcp connect to Alice, and then they use this tcp connection.

Tip: quic is server/client in one socket. quic socket must only start one time. And as runtime transport. (Default is QUIC)

And when start a new transport (no default), it will use 0:0:0:0:0 to generate a socket by system.

RFC: Under relay find can directly, changed it.
What ?

when peer stable connections is relay, and then find a directly incoming, and it is this stable connection, change the stable connection to directly.

Why ?

Better connection.

How ?

When incoming stream to server, server check it is new & check it is stable connection on relay.

if peer_list.stables.contains(peer_id) && peer_list.stables.get(peer_id).unwrap().is_relay { // }

RFC: Add request/response network state message.

Why

When want to know current network state, need a function to get.

How

Add SendMessage::NetworkState

enum SendMessage {
    ...
    /// Request for return the network current state info.
    /// params is request type, and return channel's sender (async).
    NetworkState(StateRequest, Sender<StateResponse>),
}

/// Network state info response.
#[derive(Debug, Clone)]
pub enum StateRequest {
    Stable,
    DHT,
    Seed,
}

/// Network state info response.
#[derive(Debug, Clone)]
pub enum StateResponse {
    /// response is peer list and peer is relay or directly.

RFC: message delivery feedback.
Why

Because p2p network is complex and unstable, so , add delivery feedback for stable connection.

How

use u32 as data's symbol. and only work on stable connection, not DHT.

Add new enum type ReceiveMessage::Delivery(u32, bool)

Add u32 to ReceiveMessage::StableConnect(u32, ..), ReceiveMessage::StableResult(u32, ..), ReceiveMessage::Data(u32, ..)

Add u32 to SendMessage::StableConnect(u32, ..), SendMessage::StableResult(u32, ...), SendMessage::Data(u32, ..)

Implement hole punching

I would like to help implement hole punching for understanding i think we need stun server to know peer public ip and port. Client will send udp packing to server with port and adding it public ip and address to DHT So that others can connect directly to it.

1)The two peers both open a UDP socket bound to a random local port The two peers both contact a server on the internet. This server responds and tells them what IP and port their packet was received from. Since the server is on the Internet the IP/port seen by the server is the external IP and port 2)The two peers exchange information about the external IPs and ports through some mechanism. The two peers start trying to send UDP traffic to each other. 3)Hopefully the external IP and port used by the NAT for the traffic to the server are the same as the external IP and port used for the traffic sent towards the other peer. So once both peers have sent packets out through their NATs the incoming packets match the mappings and peer to peer communication is established.

Note: This strategy will work reliablly with full cone, restricted cone or restricted port cone NATs. It will work most of the time with port-preservative symmetric NATs. It will not work with randomising symmetric NATs.

Sun can you provide some guidance for this ???

RFC: Use the group to deal with the same PeerId in the network

In the previous logic, when two same PeerID appear in the network, the node will be automatically replaced with the new peerID. This logic is based on the fact that the nodes are automatically generated randomly, but now the start_with_key interface is added, and the nodes are no longer random. May be repeated. So there needs to be reasonable logic to handle this.

When a common node receives the same PeerId, it will check whether the peer is eq. If the peer is eq completely, will only update SessionKey. If it not, it will not be replaced, and the existing node with the same PeerId will be sent to the request node.

When the node receives the same PeerId as self, it will check whether the Peer is eq completely with self. If it is eq, it is considered to be itself. If it not, it is considered to be other nodes in the same group, and is included in the management of the same group, and sends a special message to the upper-layer application.

AND. When a node receives a message, It will broadcast this message to all node in this group.

Possibility of WASM Support?

Hey there, I just found this and I was wondering what your thoughts on the possibility of WASM support might be. A quick check and attempt at compiling leads me to think that the only thing stopping it so far is its dependency on async-io from the smol crate.

For web we might be able to get away without smol by using wasm-bindgen-futures and I recently ported async_lock to work on web ( it just needed to remove the dependency on std::instant ) so we might be able to get async_channel to work as well ( or it will just work, I haven't tried it.

At that point you just have to worry about the transport. You would have to use websockets I think, and peer to peer doesn't really work on web without a signalling server we would have to take that into account to.

Anyway, I literally just found this, but I thought it looked neat and I've wondered about having a Rust library that I could on desktop native and in web to provide peer-to-peer DApps for a while so I thought I'd ask. :)

RFC: DHT update with weight algorithm.

Now Kademlia use binary distance to check if bucket is full, remove far node. In our project, if the node is to as relay, it maybe not update easily, need has a weight. weight maybe include binary distance, relay's info, online time and physical location.

RFC: Robust stable connection.
Now stable has two connect type.

Direct (EndpointStream) - listen the transport's stream. like Tcpstream.

Relay (SessionSend) - use other session's channel address as endpoint.

If listen, need handle two way.

build stable connection table, add other connect type and keep stable connect the remote peer. (by relay).

If current connection is lost, use other channel to it. and then rebuild stable connection table.

If lost connection.

If now is Directly, reconnect. (if not ok, change to Relay way.).

If now is Relay, if relay session is closed, choose other closest peer in DHT and send Ping to check.
