In order to use the existing Geode client/server infrastructure, we will be leveraging the current Geode "cache server" component.  In the current server implementation, the server expects an initial "handshake" byte, which tells the server the client protocol and how it should be handled. A client, using the new protocol, can connect with the Geode server by sending a protocol byte. Initially, we this protocol will support the following two protocols:

• byte - 110: Message will contain the whole request or response. 
• byte - 111: If the message is large then client or server can divide the message into the set of small messages. Then they need to collect all the small message and parse the whole request or response.

We may add additional protocol definitions here to indicate the use of an alternative serialization mechanism.  For instance bytes 112 & 113 might indicate the but require the server to use Protobuf for serialization of client/server messages.  How we handle other serialization libraries will be addressed when the pluggable-serialization architecture is roughed outbegin with the byte 110.
