##Our project:

####Decentralized Membership System for Health Check and Service Discovery. (For clarification, we are proposing an engineering project, not a research topic. We want to open source this project, and hope we can use this in real production environment in the future.)

Problem we want to solve: Relieve the load on central coordinator, thus improve the scalability.

Why we think this might be a problem:

#####Problem:

Agent A has an address addA. The address addA also has an aliases addA'.
When A starts, it uses addA as its address, so it computes its id = ID(addA)
Another agent B starts, it wants to join A, but it only knows the aliases address of A, that is addA', so it uses this address to to compute the id of A, which is ID(addA').
Later, when A and B exchange information, A will see an id = ID(addA'), and treat it as a different node from itself, thus A will then send message to itself.

#####To solve the problem:

	### Install dependencies

	We have two kinds of dependencies in this project: tools and angular framework code. The tools help
	us manage and test the application.

	* We get the tools we depend upon via `npm`, the [node package manager](https://www.npmjs.com/).
	* We get the angular code via `bower`, a [client-side code package manager](http://bower.io/).

	`npm` is configured to automatically run `bower install` and `gulp`. Before you run the application for the first time, simply run this command from the `www/master` directory:

	1. Update the syncPod in container_runtime branch.
	2. Add tests for rkt runtime.
	3. Think about Puller, Exec.
