Hi All, I am presently working on IXP Simulator which comes with the CD's of Intel. The issue is sending packets to the microengines. As far as I know there are 2 ways of passing packets to the microengines a) Using the IX Bus which comes with the simulator. b) Passing packets from outside the Workbench ( Foreign Model ). I am sucessful in passing packets from the IX Bus, but do not have any idea of sending packets from outside the Workbench ( i.e. from the network ) so that I can manipulate the packets going to the IXP. I think this can be achieved by creation of some DLL's on Windows ( as specified in the manual ) which can be linked to the Simulator. Can any one out there give me some guidance of how to generate these DLL's and the code ?? Or if you already have some sample code which works this way, can you pass it on to me ?? The idea is to send and receive packets from the network (another m/c) to the Simulator. If these is any other method by which we can achieve this, pls specify. Thanks, Regards, -Murali IISc.
