QNET Protocol Overhead


We’re working on a paper to justify a number of design descisions we’ve
made. One of them is the use of QNET instead of tcp/ip over our wireless
links of our system. We would like to know about the overhead requirements
of the current (QNX 6.3) implementation of the qnet stack. How much
bandwidth does the lastest QNET incarnation use in the protocol sections of
a packet?
