Hi,Andy
I don't understand what you mean.I have a adsl router based on mips linux2.4.17.In this adsl router,one side is 100Mbit ethernet card,another side is adsl line,as following:
LAN------(ethernet)--------ADSL Router------(ADSL line)-------------WAN
On this adsl line,it can configue rfc1483bridge or router,or pppoe to get wan ip from ISP. I think this side(upstream) is the bottleneck link. I ported iproute2/tc on this router and i can control traffice on the upstream line.
But I got completely no idea for doing these: (from TR059 Technical Report DSL Forum)
1.The device MUST support the capability to fragment AF and BE traffic in order to constrain the perturbing impact of AF and BE packets on EF traffic delay, for example using a mechanism such as MLPPP LFI.(RFC1990)
2. The packet size threshold before fragmenting AF and BE packets MUST be configurable.
Thank you very much!
