many many thanks to mohit , abiola and francis. i have spent the past few days poring over the lartc and diffserv archives. although i now know how to use the 'tc' commands , i yet am unaware of any way to test if tc works as it should do. presume it can be tested by passing packets throught the network. if any body in here who has implemented diffserv and aplied it to set of mpls routers can tell me about how to go about it, i'd be grateful. thanking you in anticipation nerd (have attached the list of responses i received in the hope that they will be of use to other members.) From: Mohit Singh <mohitsingh76@yahoo.com> u can implement it using open source libraries available for linux implementations - e.g. RED /RIO for linux ! to check how it works , u need to ascertain quality of the data u are processing. e.g., for VoIP qos, u need to test voice quality depending on system invloved. plz be in touch... mohit ------------------------------ "Abiola O. Adegboyega" <agboyega@sce.carleton.ca> Hi there! 1. Use a network simulator (ns-2 is available for free at www.isi.edu/nsnam/ns) 2. Follow the instructions and install on unix. 3. There are example scripts that you can simulate and observe results 4. You might want to use some perl scripts to measure average queue lengths, bandwidth provisioned etc. If u need further help, let me know. Rgds, 'Biola. ------------------------ From: "Scott Allen" <scott.allen@telesuite.com> If you receive direct replies to your email, could you forward me copies of the DiffServ advice? I also am tasked with building a DiffServ network (using a Cisco infrastructure however, not Linux, but who knows how things might change) and I'm interested in the replies you receive. If they are global replies to diffserv@ietf.org <mailto:diffserv@ietf.org> , of course, I'll see them. Thanks. Scott Allen Chief Information Officer TeleSuite Corporation 937-836-9995 option 2 ---------------------------- FrancisDomoney@aol.com you could try looking at this site http://www.nwfusion.com/auddev/pop/LANFOC208.html then hit the Cisco site for some teach yourself tutorials. then arm yourself with a modelling tool and build a model of the network. When it gives you the required theoretical performance buy some routers and build it.
