Its 5Mbps on ATM actually... We can scale it up as needed, but we are only paying for a QoS of 5Mbps.... Thats MORE than what we need right now as our DS1 service is just starting to reach capacity. Our current situation is that we have quite a few devices on two physical segments (terminal servers, mail, news, DNS boxes, customer equipment etc...) and our collision rate is starting to go up. The FreeBSD boxes are using the de style DEC 10Mbps ethernet cards... I can upgrade them to 100Mbp, but there is not much I can do about the numerous terminal servers which have just 10Mbps. I think a switch would definitly help reduce the collision rate, but since most of the traffic is from everything to the router and vice versa, I thought it would be a good idea to sort of have multiple paths to it. i.e. 3 10Mbps physical routes (made up of our admin work stations, customer equipment and terminal servers), and then 1 100Mbp route from the FreeBSD box to the rotuer, I would hopefully be able to reduce the collision rate and move things along a little faster. ---Mike ********************************************************************** Mike Tancsa (mike@sentex.net) * To do is to be -- Nietzsche Sentex Communications Corp, * To be is to do -- Sartre Cambridge, Ontario * Do be do be do -- Sinatra (http://www.sentex.net/~mdtancsa) *
