Hello Peter Sir,

Thanks for replying and guiding me . Sir u r right i am a beginner in using the OPNET TOOL and really doesnt know the meaning of the terms used in OPNET. thats why if you see my previous questions u will find i have asked of suggesting a book for learning OPNET TOOL . 

Anyways, sir regarding the ethernet based client server model.  I am using OPNET MODELER 14.5 for my research work.sir i am learning to make models in OPNET 14.5 from tutorials available on internet. so from seeing there i have made a small office model in which i have made a multiple switch ethernet based network consisting of server and 10 workstations  as nodes and defined there attributes .  sir u please tell uptill now is it ok.

after that i have joined them using 10BaseT ethernet Links and assign an application config. and Profile configure.in the model  for inserting traffic to the network and define its attributes also. Then after assigning all parameters to the server,wkstations and to links i verified the links ,it was verified OK.  After that I go to the individual  statistics of the OPNET TOOL  and select ethernet load in bits/sec and from there giving time to compile the model and give results as 20 minute and executed it and after executing it the above error [Errors given in file (C:\Users\ritesh\op_admin\tmp\cc_err_2220] comes. 

Meaning of this error i am asking. Now please tell me the mistakes i have done in making the model. I accept that i have done wrong but i am not getting it where the mistakes have done and since i am just a beginner please guide me how to make networks and models in OPNET 14.5. I am doing my Research work in VOIP technology and basically want to do my analysis on VOIP only using this OPNET TOOL. i want to design networks and want to do analysis of its Key parameters like delay,Mean opinion score,echo,throughput,etc.

Second thing sir,regarding copying a model means when we have made a model or network or scenario,etc in OPNET TOOL and save it. Now if we want to see the model in word document then how can I copy and paste that model or scenario or project in word document. This thing is needed because after doing analysis i have to write research papers and there in Figures I have to paste the model that I have made and research papers are written in .doc format or in .docx format.Thats why i have written i need to know the function in OPNET MODELER TOOL 14.5 of how to copying the model or project and paste it in .doc format.

sir it is very silly thing but i am a begineer so such small things i have to learn. I hope this time i am able to clarify my problem in detail.

Peter sir please reply my queries

Thanking you,

Ritesh sadiwala
