2 Presentation Layout Background and motivation Multi-ID and multi-locator (MIML) Service scenarios with MIML Items for research & standardization Conclusion ITU-T Kaleidoscope 2010 Beyond the Internet? Innovations for future networks and services 2

3 Background and Motivation Application Data link Physical Use IP address as Identifier Use IP address as Locator Data link Physical Application Data link Physical Host Link Router Link Host Current Internet: IP address used as both ID and Locator Future networks demand ID and Locator split For mobility and multihoming: change locators without changing identifiers Scalable routing, traffic engineering: use different scoped locators, dynamically map them ITU-T Kaleidoscope 2010 Beyond the Internet? Innovations for future networks and services 3

4 ID/Locator Split Architecture Overview Use IDs Application Map IDs to Locators Application Use Locators Data link Data link Data link Physical Physical Physical Host Link Border Router Link Host Different name spaces for IDs and locators ID locator mapping by the layer ITU-T Kaleidoscope 2010 Beyond the Internet?

7 Why Multiple IDs? a) network-protocol independent multicast, group-cast, or geo-cast b) service differentiation c) optimal network/path selection d) private and public communication e) dynamic relationship between users, services, and hosts ITU-T Kaleidoscope 2010 Beyond the Internet? Innovations for future networks and services 7

8 Why Multiple Locators? a) mobility b) multihoming c) routing d) DTN e) heterogeneous network protocols f) privacy ITU-T Kaleidoscope 2010 Beyond the Internet? Innovations for future networks and services 8

12 Research and Standardization Items (1/4) 1. Service Representation unique representation of service name + quality application_name service_content_name quality{parameters=values} e.g., video: movie_titanic-1997 bw=10mbps, delay=10ms service logical locator application_name host_name service_content_name list{parameters=value} e.g., video: server1#providera.com movie_titanic-1997 bw=10mbps, delay=10ms ITU-T Kaleidoscope 2010 Beyond the Internet? Innovations for future networks and services 12

13 Research and Standardization Items (2/4) 2. Hostname Host ID, Locator Resolution System to find host ID and locator from hostname 3.
