  1. Quality of Service & Emergency Services: Does it make sense? Tony Rutkowski Panel Members

  2. Barbara Stark – Position Statement • Short Answer: Yes, where appropriate • Which networks are involved? • Core Internet (many interconnected providers) • Emergency Networks (operated by public safety and other government agencies) • Private Networks (corporate and home networks) • Access Networks • Tightly-controlled access, e.g., cell / mobile phone networks (outside of my scope) • Not-so-tightly-controlled access, e.g., broadband connections, some hotspots

  3. Barbara Stark – Position Statement • Which traffic to mark, and how? • “sos” SIP, and associated RTP (voice and video) • DSCP, but only when trusted (which DSCP? EF (AF for video)? New DSCP for emergency services?) • Destination (to emergency network) or origination (from emergency network) IP address may be useful in some networks when marking is not trusted. • Other means for trusting nature of traffic? • Priority vs. Admission Control • Since other VoIP traffic will be sharing EF queues in some networks, is there a need for separate emergency DSCP with admission control for the case when call volumes spike during a disaster?
