چکیده
Many researchers have explored enhancements of the Internet s best e ort service model that allow real time and other inelastic applications to obtain preferential Quality of Service However these applications are limited to utilizing the opportunistic shortest path routes pro vided by the current routing infrastructure To better support real time applications this paper introduces extensions to interdomain multicast routing to scalably compute and install alternate paths and non opportunistic or pinned routes We present a simple multicast setup protocol for installing alternate paths and discuss how it prevents loops Furthermore we include the results of a simulation study to demonstrate the viability of using localized route construction to nd adequate alternate paths
