$1$ Components

There are two components that you will be building as part of this assignment: a registry and a

messaging node.

$1\mathrm{.}1$ Registry:

There is exactly one registry in the system. The registry provides the following functions:

A$.$ Allows messaging nodes to register themselves. This is performed when a messaging node

starts up for the first time.

B$.$ Allows messaging nodes to deregister themselves. This is performed when a messaging node

leaves the overlay.

C$.$ Enables the construction of the overlay by orchestrating connections that a messaging node

initiates with other messaging nodes in the system. Based on its knowledge of the messaging

nodes $($through function A$)$ the registry informs messaging nodes about the other messaging

nodes that they should connect to$.$

D$.$ Assign and publish weights to the links connecting
