Yes, a typical scenario would be a set of Web clients on an over- provisioned (maybe non-ATM) LAN, talking via a Web cache to a Web server. If cache and server are on ATM, they can use Arequipa on behalf of the clients. Given that RSVP is now slowly getting deployed and that also RSVP over ATM implementations are starting to appear, I wouldn't recommend to design new "general" solutions exclusively around Arequipa, because the end-to-end ATM requirement is just too easily violated. However, if you can be reasonably sure that the parts needing guaranteed QoS are interconnected with ATM, a solution based on Arequipa may still be much easier to set up than the corresponding RSVP equivalent. - Werner -- _________________________________________________________________________ / Werner Almesberger, DI-ICA,EPFL,CH werner.almesberger@lrc.di.epfl.ch / /_IN_R_131__Tel_+41_21_693_6621__Fax_+41_21_693_6610_____________________/ |
