[LARTC] buffer size

2003-11-11 Thread yuxiao jia
Hi Stef   I have one flow, I mark as EF class, then I use CBQ to control rate   in tc script there is place to control queue size (buffer size) for example   ## Definition of the CBQ leaf classes to support EF and BE## EF class$TC class add dev eth1 parent 2:1 classid 2:5 cbq bandwidth 100Mb

[LARTC] HTB algorithm

2003-07-30 Thread yuxiao jia
Hi Stef I try find the algorithm of HTB, generally HTB shape is based on the Token Bucket Filter (TBF) algorithm I still want know the theory , I went to Martin site, most link doesnot work http://luxik.cdi.cz/~devik/qos/htb/ Could you tell me where I can find HTB algorithm? thanks Regards

[LARTC] under Linux how is FTB derived from routing table

2003-06-20 Thread yuxiao jia
Hi There are two processes about routing. (as deepak email said) Forwarding is a process of moving packets from input to output based on: - Forwarding Table - Information in the Packet. Routing: The Process by which the Forwarding table is built and maintianed. - One or more routing protoco

[LARTC] how to emulate large IP routing table

2003-06-15 Thread yuxiao jia
Hi all I am conducting the experiments comparing IP router forwarding delay and MPLS LSR forwarding delay, it is obvious in theory MPLS in Core should be faster than IP, but for small netork (only have several core routers), result show it is not, this is why I want emulate a large IP routing tabl
