@aki, I don't work in the ISP industry! Never have actually but I believe they use VLANs and rate limiting. Most of them actually use MRTG as their tool of choice for monitoring the bandwidth implying this would be clearly stated in an SLA. I am sure there are guys on the lis who work for ISP's. Here is hoping they can shed more light on this. On Wed, Sep 30, 2009 at 8:16 PM, Denis G. Wahome <dwahome@gmail.com> wrote:

@aki, VLANs might help to some extend but only to stop network broadcast which is helpful to some extend, Rate-limiting being a form of QoS will help a great deal and probably add traffic shaping
@Net Net
Locally i think providers use vlans for directing traffic thus creating the circuit over WiMax, fibre etc then as Aki says they do rate limiting to set the up and down throughputs then further upstream use a bandwidth manager eg. allot, packeteer(now Bluecoat) to enforce the SLA per contract. From there some ISP use cache technologies and DPI to do application acceleration and enforce policing. BTW i wish all ISP would not do cache and DPI stuff on client internet circuits.

Guys, wondering on the VLANS and rate limiting first, before we go down MTUs? Ok, I've been out of touch with dist networks for a long while, so am catching up on the technologies in deployment locally. Wimax, Fiber. I assume that they are all using VLANS for circuits and rate limiting applied to set circuit throughputs, am I correct in thinking this? In case of point-point and point to multi-point? And is rate limiting still used to set some part of SLAs? Or have the entire industry headed towards wi-fi broadband concept?
Rgds.
