Future networks demand
ID and Locator split
Current Internet: IP address used as both
ID and Locator
For mobility and multihoming: change locators without changing identifiers
Scalable routing, traffic engineering:
Pune, India, 13 – 15 Dec 2010: use different scoped locators, dynamically map them

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

Summary and Future Work
Overviewed ID/locator split-based architecture of future networks distinct namespaces for IDs and locators mapping functions in the Identity Layer helpful for mobility, multihoming and routing scaling
Introduced multi-ID, multi-locators
Multi-ID: to convey application requirements to networks
Multi-locators: to optimally utilize heterogeneous networks
Items for standardization service representation and discovery, host ID configuration, id-tolocator mapping algorithm, etc.
Future work carry out experiments in large scale to prove the concept bring outcomes to SDOs
