	att_abstract={{Multimedia distribution, especially broadcast TV distribution over an IP  network requires high bandwidth combined with tight latency and loss  constraints, even under failure conditions. Due to high bandwidth  requirements of broadcast TV distribution, use of IP-based multicast to  distribute TV content is needed for capacity efficiency. The protection  and restoration mechanisms currently adopted in IP backbones use either  IGP re-convergence or some form of Fast Reroute. The IGP re-convergence  mechanism is too slow for real-time multimedia distribution while a  drawback of fast reroute is that since they re-route traffic on a  link-basis (instead of end-to-end) they can suffer traffic overlap during  failures. Here traffic overlap is defined as the same traffic passing  through the same link along the same direction more than once, which  requires more link capacity. We propose a method that interacts with Fast  Reroute and multicast to minimize traffic overlap during failures. We also  present an algorithm for link-weight setting that avoids traffic overlap  for any single link failure. Performance analysis shows that the proposed  method improves network service availability and significantly reduces the  impact of failure events. version 2 record added in error; please see version 1 for paper. }},
