### Responsibilities
Each micro service is responsible to generate its own messages and keep track of messages coming from other
micro services. This is necessary so that any micro service may reach our any other micro service. This provides
discovery for any micro service. All current micro services provided in OpenWiFi perform these functions. If you leverage
the C++ framework, this functionality if performed automatically.
### `event-type`
When a service joins the bus, it should generate an event-type of `join`. When a service shutdown, it should generate a `leave` event-type. Every 30 seconds, a service
should generate a `keep-alive` message.

#### `join` event
When a service start and joins the bus, it should generate an event-type of `join`.
### `leave` event
When a service shuts down, it should generate a `leave` event-type.
### `keep-alive` event
Every 30 seconds, a service should generate a `keep-alive` message.
### `id`
You should generate a random number from some unique factor for the system. This ID is used to identify different services. You should reuse that ID
when you restart.
## Micro-service maintaining bus state
A micro-service should maintain its own lists of available micro-services by looking at the messages it receives and keep a list.

The build is done in 2 parts. The first part is to build a local copy of the framework tailored to your environment. This
framework is called [Poco](https://github.com/pocoproject/poco). The version used in this project has a couple of fixes
from the master copy needed for cmake. Please use the version of this [Poco fix](https://github.com/stephb9959/poco). Building
