## Communication Protocol
Port 42914 is used for Master => Slave broadcasting
Port 42915 is used for Slave => Master return broadcasting
Messages are sent over rednet with the protocol `ccstoragenet`.
### Packet Format
@ -52,17 +50,15 @@ Packet format is uniform between master <-> slaves and is structured like so:
| `itemquant` | false | int | Quantity of the aforementioned item |
| `destination` | false | int | The CC ID of the intended recipient of the item |
Messages are sent over rednet with the protocol `ccstoragenet`.
### Slave Node Initialization
* The slave starts up
* The slave starts up and immediately listens for messages
### Master Node Initialization
* The master node starts up
* The master node sends a packet with type `ping`.
* The master node listens for `pong` packets for a configurable timeout.
* The master node listens for `pong` packets from all slaves.
* The `sourceid` of all `pong` packets is recorded for statistics displays. This cached data is only used for user display. Node availability is evaluated at request time.
### Inventory Search (query)
