hi ,
yes thats true , we did had problems if all function had their worst cases,
so i modified it to .

while(1){
function0   tcp stack process
function1   h/w process 
function0   tcp stack process
function2   tcp server process (tcp listener)
function0   tcp stack process 
function3   tcp client process (tcp opener )
function0   tcp stack process
function4   udp server/client process 
}

Regards,
Mrutyunjay B Patel

That means you've got a worst case of 1.5 seconds between calls to one
of those functions.  This might be a problem as you won't be able to
meet the timing requirements of TCP's timers for example.  You certainly
won't get high performance this way, unless I've misunderstood your
approach.
