Keywords: SCAMP, scalable membership, gossip, WebRTC

This project is a Nodejs implementation of the Scalable Membership Protocol (SCAMP) [1] which is a gossip that automatically resizes its neighbourhood tables in order to fit with the size of the network using local knowledge only. For instance, a peer within a large network knows only a small subset of the peers. Still, the links between the peers create a connected graph.

The project rtc-SCAMP-mbr uses WebRTC which allows creating peer-to-peer connections within the browser. To our knowledge, there do not exist any implementations which do not rely on a central server to ease the initialisation phase of the membership. Thus, this project aims to fill this gap. Such implementation would allow building distributed network by only manually sharing a piece of data (e.g. by mail, via URL...).

You can use the node packet manager to get the module: $ npm install rtc-scamp-mbr

Please check the p2pnetwork API.

An example is available at the rtc-SCAMP project page which uses this SCAMP membership protocol paired with a simple broadcast mechanism. This composition creates a working network within your browser.
