Varun,

When HP implemented SIGCOMP support they did it through a plugin 
architecture.  Unfortunately, not compression plugins are released. 
Compression is only supported for UDP.

There is a pretty simple interface that would need to be implemented 
consisting of three functions:

  int (*comp_uncompress) (void            ** state,
                          char             * msg,
                          unsigned int     * msg_len);
  int (*comp_compress) (void         ** state,
                        char          * msg,
                        unsigned int  * msg_len);
  void (*comp_free) (void ** state);

The compress function is called before sending a message and the 
uncompress function is called after receiving a message.  The free 
function is called from the call class, but the allocation is taking place 
using a method in the socket structure.  I have not used this 
functionality, so I can't really provide much more information.
