## Suggestions
### Node health
As a useful metric to define and implement for determining quality of provided service by a node:
- unhealthy - no peer connections are available regardless of protocol;
- minimally healthy:
- Relay has less than 4 peers connected;
- Filter and LightPush has one per each peer connection available;
- sufficiently healthy:
- Relay has minimum 4 peers connected;
- more than 1 connection in Filter and at least 2 connections available in LightPush;
### Peer and connection management
Each protocols should retain a pool of reliable peers. In case a protocol failed to use any peer more than once - connection to it should be dropped and new peer should be added to the pool instead.
