[alto] New version: draft-schwan-alto-incr-updates-02.txt

["Schwan, Nico (Nico)" <[e-mail]>]

All,

we have submitted an updated version of the "ALTO Incremental Updates" draft which analyses options for partial updates of ALTO Network and Cost Maps. In this version we have further detailed the solution which is based on Filtered Map Services. As suggested in the last meeting we have also included a short numerical evaluation of the most promising options in the draft. Our main findings are that for more than 100 PIDs partial updates are useful, and that the solution based on Filtered Maps is more efficient than JSON Patch in terms of needed bytes for encoding.

Any comments on the discussed options, the numbers, or anything else are welcome!

Thanks,

Nico

Abstract:
   The goal of Application-Layer Traffic Optimization (ALTO) is to
   bridge the gap between network and applications by provisioning
   network related information.  This allows applications to make
   informed decisions, for example when selecting a target host from a
   set of candidates.

   Therefore an ALTO server provides network and cost maps to its
   clients.  This draft discusses options on how to provide incremental
   updates for these maps, with the goal of reducing the amount of data
   needed for transmitting the maps and shortly evaluates the two most
   promising options.
