Hi,all I am using iproute2/tc to manage bandwidth and control traffic.I must realize these two tricky functions in mips linux(kernel 2.4.17): 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. I am completely stunned.I think these functions are about qos,and I heard that Cisco realize MLPPP LFI in its qos function. Would anyone please supply some suggestion?Thank you very much!
