Hi all, how many people actually implement a QOS design within an ISP network which is for data heading from a DSLAM or router TO the customer ? I am interested to know of those that do are you dynamically managing the QOS using prioritisation of packets or are you hard setting speeds in multiple queues to manage the VOIP quality heading to the customer ? We have written a system which dynamically prioritises packets to the customer, it tears down the default queue created at PPPOE login time and then builds a new queue structure with a parent and two children, one for VOIP and one for everything else. It works very well, however the Mikrotik priority system is a little slow in reacting sometimes for VOIP and we still see some packets not getting through in front of a large download which is smashing the connection for example. We can obviously reduce traffic bandwidth in the non-VOIP queue but that would be a permanent thing so even when there was no VOIP traffic they still wouldn't see maximum bandwidth. We know how to handle both scenarios but I am just interested in how others handle it or whether they do it at all.... Regards Paul
