Lost Teeth Impact Total Health In the past, the loss of teeth was dismissed as a natural part of the aging process, and dentures were considered a normal sign of old age. While such ignorance is rapidly becoming a thing of the past, there is still not a general awareness of the seriousness of edentulism (the condition of being completely toothless). Multiple tooth loss is most commonly caused by periodontal disease, i.e.. gum and bone disease. Periodontal disease has a high statistical correlation with chronic debilitating disease, such as diabetes, cardiovascular disease and arthritis. So it is not very surprising that studies now show a shortened life expectancy by as much as 10 years for persons who have lost their natural teeth, when compared to those who have kept their teeth. In addition to longevity, quality-of-life differences are just as significant. The functional efficiency of dentures has been measured to be only 20% of that of natural teeth. Can there be any doubt that nutritional deficiencies will be much more prevalent in those without their natural teeth? Loss of teeth often causes a feeling of loss of wholeness and a sense of deterioration and aging. Given these factors, preservation of the natural teeth is integral to whole-person wellness.

FreeBSD 7.2, mpd5.3 + ng_car + ng_bpf (rate-limiting on this machine - the perfomance of traffic processing is very good, because ng_car & ng_bpf is in kernel space, but have trouble described in PR kern/137881, i think on FBSD 7.0 it may be works fine, but no test are made, i'm busy) 3. Use PPPoE concentrator and traffic shaper/rate_limiting on different machines - it is best but is very older practice.

It seems, that even 96 FTTH ports with 100 MBit each do not hit the limit of a 1GE upstream, so the now I could test the "Sun Fire X4100M2" becaus it has four 1GE ports, which mean, I can use one as upstream and then connect the three others to up to three FTTH DSLAMS...

The solution you are implementing will mean to make hundreds of users share the same broadcast domain. As all your FTTH and other DSLAMS would be working in bridge mode. This scenerio is not safe as if anyone of your clients will start his own pppoe server you will be in strange trouble, there can be other issues too. I guess your DSLAMs must have built in pppoe support and radius client, if its there then every port of dslams can be separate broadcast domain. This will cause you extra routing management (depending upon your scsnerio) In case your DSLAMS have no pppoe feature then i would suggest you to at least put every DSLAM's uplink port in deparate VLAN and connect pppoe server using trunk port or multiple single ports. And before implementing this solution consult your DSLAM vendor cause ive observed problems in ipdslams when used in bridge/transperant mode.

There was someone on the which? has? suggested? me? to? use FreeBSD, because the PPPoE it is already build to? authenticate? against Radius. So, what I like to know is, if I have a 1GE and 10GE network,? how? many clients can? one? PPPoE? Server? handel? and? what? are? the? CPU/Memory requirements? There is a little problem to get small but? reliabel? Servers? with? TWO 10GE interfaces.

Please note, that I am ongoing ISP with over? 150.000? customers? in? DE between Freiburg and Karlsruhe (Baden-W?rttemberg)? and? using? consumer mainboards is NOT reliabel since in the last 6 years I lost at least? 20 per year in 280 Low-Cost Servers. A "Sun Fire X4100M2" would be more reliabel... but even the smallest CPU would be overkill because the machine has only 1GE interfaces. Any suggestions?

The problem is, HOW many VLANS can you open? If I use the Transmode TS DWDM (GE) and/or CWDM (10GE) then I am limited to 4096 VLAN's. So, if you have inside this network business customers which require seperated VLAN routing you run out of VLAN's Yes, I can use a biger system, but this cost at least twice of the "Transmode TS" system. Juniper is much more expensive. > And before implementing this solution consult your DSLAM vendor cause > ive observed problems in ipdslams when used in bridge/transperant > mode. I am already in contact with Iskratel in Kranj/Slovenia, because the Distributor in Germany is a little bit to small for the Project and I get direct help from there engineers to implement this. The only difference between is, that my Servers are running entirely "Debian GNU/Linux" and where it fit better, FreeBSD.
