  1. Route Construction Jonathan Rosenberg Cisco Systems

  2. Problem Definition • Lack of clarity on how a UA determines Route header set for a request • Lack of definition on handling of 305 response

  3. Sources of Route • Record-Route • Configured outbound proxies • DHCP • 3gpp air interface • Config framework • 305 response • Email discussion on usage in populating Route header, not Contact • Service-Route

  4. Specific Points of Confusion • Do I include Route header field in my REGISTER? • Generally, what methods? • Does service-route override default outbound proxy?

  5. Goal of Draft • Define an explicit algorithm for construction of Route at UA for each request, clearly defining how each route source relates • Define an explicit algorithm for construction of service route at proxy, with specific points of variation

  6. Question • Interest in this work?
