The ADSL2 Line MIB contains the upstream and downstream information that is "current" within an ADSL2+ modem. A similar table is present in the original ADSL line MIB as well (Full-rate DMT modems for example). Devices in the home could query the MIB objects to obtain upstream and downs

Clearly, a third party querying an ISP for provisioned link speed associated with any IP address has tremendous privacy concerns. However, what I am thinking is that an ISP managed ALTO server (at the edge router) disseminates this information only to a DSL/cable modem when the modem attempts

Salman, I don't remember if the WG ever decided whether the 'provisioned link speed' was in scope or not. But as an ISP, I have always been uncomfortable in sharing this data item in an ALTO service. In North America, broadband connectivity may cost between ~$15/month and ~$250/month, depending l

[alto] 'Link capacity' in scope?

2009-06-02 Thread Salman Abdul Baset
When a home customer purchases a [high speed] Internet plan from an ISP, the ISP typically promises a certain upload/download link capacity for the plan. In the old days of dialup, a device using a modem established a point-to-point connection with the ISP and knew the link capacity which w
