Messages communicated between the client and server follow the same format, but have different meanings depending on which end is the recipient. A message's intent is determined by its packet ID, a unique identifier that tells the client or server how it should react to the received message. A message id that incites bidirectional communication between the client and server should typically be associated with the same message id on the client as on the server, so as to avoid confusion.
A packet of communication between the client and server is considered to be a seamlessly connected regions of bytes, the boundaries of which are defined in the header of the packet.

All references to the 'byte' in this document refers to individual 8-bit octets, as is the de facto standard in modern computing. All binary-encoded multi-byte quantities sent in a packet are to be sent in network byte order (big endian).

### Packet IDs
A packet ID may have a specific "direction" of communication, in that an endpoint may either act as a _requester_ or a _responder_. A _requester_ is an endpoint that drives all of the communication on that specific packet ID, while the _responder_ is responsible for providing a timely response to the requests it receives. A _responder_ for a specific packet ID should never send that packet ID unsolicited; either the packet will be ignored or the other endpoint will close the connection. Any packet ID marked as bidirectional may be initiated by either endpoint at any time.
A _blind requester_ is an endpoint that sends out a packet of a certain ID and either does not expect a response or expects a response on a different packet ID.
## Body
The message body immediately follows the header with no separator, and consists of a sequence of byte regions as defined in the header that are joined together without any separator. The position of a byte region in the body should correspond to the offset of the length segment in the header.

## Master/Slave Servers
To keep track of the status of multiple servers from a centralized point that the client may query, each server must be able to communicate with a "master" server that will record and dispense information regarding all servers to clients. All servers that report to the master server will hereby be refered to as "slave" servers.
