Question

Im planning to deploy a version for some IETF drafts and need some code references or guidance. Im familiar with basic TCP sockets but want to know how to translate requirements into code.

Example: Format for the Session Initiation Protocol (SIP) Common Log Format (CLF)

Would like to see how to translate:

 0          7 8        15 16       23 24         31
  +-----------+-----------+-----------+-----------+
  |  Version  |           Record Length           | 0 - 3
  +-----------+-----------+-----------+-----------+

   Version (1 byte):  0x41 for this document; hexadecimal encoded.

   Record Length (6 bytes):  Hexadecimal encoded total length of this
  log record, including "Flags" and "Record Length" fields, and
  terminating line-feed.

into code.
How can I define Version?
Which type?
Int, char, etc?

Thanks

Instead of writing it from scratch, I would suggest to use applications like Jboss Netty , Apache Mina or Grizzly. They are specifically targeted for high performance protocol development.

Here is an example of Grizzly being used for Supporting SIP.
