Re: [alto] ALTO Cost calendars in wireless access networks

["Scharf, Michael (Michael)" <[e-mail]>]

Hi Uwe, all,

Personally, I am not sure whether a single RAN cell is indeed the right granularity for PIDs.

But draft-ietf-alto-deployments is a WG document and in general the editors have been open to suggestions for further realistic deployment cases of ALTO. draft-ietf-alto-deployments has some text already on mobile access networks, albeit at a much larger granularity of PIDs.

As usual in the IETF: Propose specific text ;)

Best regards

Michael

Hi Sabine,

Is http://tools.ietf.org/html/draft-ietf-alto-deployments-10 the appropriate place to add these?

Kind regards,
Uwe

Hi Xiao and Uwe,

The cellular or other access use case also calls I think for looking at related ALTO Service deployment cases.
Best,
Sabine

Hi Uwe,

Your document sounds like a very reasonable and useful extension. Just have two related thoughts:

1. Have you considered your cells extension using PID properties? The relevant draft is here: http://tools.ietf.org/html/draft-roome-alto-pid-properties-02#section-4.2 I believe the PID property document provides a solution to both requirements in your document (via Solution B).

2. Since the nodes change cells frequently, do you think this extension would benefit from incremental updates? The incr update document (http://datatracker.ietf.org/doc/draft-roome-alto-incr-update-sse/) provides the SSE framework, but I am not sure how convenient SSE is to mobile networks.

Best,
Xiao

Hi Sabine,

Thanks for the pointer. Yes, I think your proposal will meet the expectations of the sketched use cases.
In fact, our proposal is orthogonal and tries to address the problem that in mobile networks, the network attachment
point can be one additional important parameter that should be addressed in ALTO.

So far, ALTO helps to decide “where to connect to” (where: the endpoint that provides the service).
The cost calendar enhances this to become “when and where to connect to”.
In mobile, the whole picture would become “via which cell/access, when and where to connect to”.

Kind regards,
Uwe

Hi Uwe,

I see that your draft http://tools.ietf.org/id/draft-rauschenbach-alto-wireless-access-00.txt will be presented in the next ALTO WG session.

Given that your draft poses the need for a calendar in its following sections 3.2.1.  Cost calendar to extend battery life for background tasks and section 3.2.2.  Cost calendar to optimize application sessions, you may want to look at http://tools.ietf.org/id/draft-randriamasy-alto-cost-calendar-02.txt, that proposes ALTO cost calendars and will be presented during the ALTO WG session as well, as it would be interesting to see how this proposal may meet your expectations.

Best regards,
Sabine
