networking - Configuring TCP for a very high volume network -


currently experiencing network issue in system consisting of 2 sensors (each data rate of 1khz), communicating windows 7 operating system via ethernet link. program running on windows system written in java.

the issue: program runs normal undefined period of time, before coming halt – due tcp native buffer overflow.

my instincts leads me believe due tcp rwin – in consumer slow in comsuming packets stack, leading buffer overflow.

looking @ captured packets nic, final sequences before crash this: large ack block, followed rst each sensor, before shutting down connection. can see on each rst wim size set 200, whereas before upwards of 1000.

enter image description here

could offer suggestions on how begin solving issue? in research done @ point, i’m still @ loss how solve one.

if sensor sending rst, connection got closed @ sensor. should investigate why happened? 1 reason might connection got timed out -- perhaps tcp@sensors trying send , not through. can run trace tool (like tcpdump/windump) @ sensors?
