Hi, I have made some changes to the file sch_gred.c to modify the GRED queueing discipline to support the following features: 1) The first virtual queue should get absolute priority while dequeueing (not caring if the others get starved) 2) While in equalise mode and with RIO mode enabled, the packets in the first virtual queue should not be count...

Group, I am reading about tc (traffic control) and willing to get my feet wet. As requirement, there should be HTB compiled in the kernel. I grabbed a Mandrake 8.2 distro, and didn''t installed the kernel source. Anyone knows if the HTB is compiled in Mandrake 8.2, or point a way to find that out? I tried to read the /usr/src/kernel.xxxxx/.config file, but it doesn''t exists.

...f I set the priority of two virtual queues as equal ? 3. If I want that the Average queue length being used before dropping a packet should be equal to the sum of the average queue length of all the virtual queues, where would i have to make changes in the source code ... ie, just making changes in sch_gred.c would suffice or I have to make changes to some other files also ...

Hello, We know, VQs are used in Gred to offer different schedulers, in order to make clear what the VQs are, I have read the sch_gred.c in net/sched/. In the function gred_enqueue(), at first it will find the VQ(q) according to the lower four bits of the skb->tc_index, then some parameters of the q is modified, such as q->packetsin and q->bytesin. At last the packet was put into the physical Queue using __skb_queue_tai...

I''m successfully using HTB + GRED to shape traffic based on the DSCP field. I would like to strip the DSCP and possibly replace it with normal ToS bits on egress traffic leaving my network. Leaving DSCP set is pointless, and could potentially cause problems with some ISPs that use DSCP internally I suppose. Setting ToS bits would seem ideal as most networks still honor it to varying
