Excerpts from Lixia Zhang on Thu, Sep 11, 2008 08:52:16AM -0700:- multipath transport solutions (e.g. like the one Mark Handley presented in Dublin), potentially can bring great benefits to users and applications. - as I presented in Dublin, transport solutions can work, orthogonal to whether using PI or multiple PA addresses. - the only thing that seems problematic is an attempt to scale the routing system by relying on all edge networks doing renumbering.I believe all the pure endpoint-based solutions scale routing by making all addressing hierarchical. Endpoint-based solutions, including multipath, still generally expect an endpoint to know its many addresses
2/ knowing many addresses is one way to get there, not necessarily the only way
1/ even if one uses many addresses that corresponding to many providers, one still does not have to use PA addresses (see my Dublin talk)
and when a site changes its upstream connections it needs to reconfigure all of its services and ACLs to deal with the new addresses.
