  1. HINLO: An ID/LOC Split Scheme for Mobile Oriented Future Internet Heeyoung JUNG ETRI (Electronics & Telecommunications Research Institute) Republic of KOREA

  2. Background • Mobile trends • Wide popularity of smart phones and emergence of various wireless/mobile networks • “The number of mobile users will be more than 1.6 billion in around 2014 and thus exceed the number of desktop users” [Morgan Stanley report 2010] • The mobile trend was not considered in the design of original Internet • Many (possible) limitations in mobile environment • Typical one is overloaded semantic of IP address • Major source of mobility and routing scalability • ID/LOC split is being recognized as a promising solution • HINLO (Host Id and Network LOcator) is an ID/LOC split solution for mobile environment

  3. ID Requirements for Mobile Environment • Mobile host is mandatory and fixed host is special • Mobile hosts will be dominant • Host ID and LOC should be separated • LOC for routing and ID for upper layers • ID for host itself is necessary • To efficiently support mobility and multi-homing • Support of hosts with multiple interfaces • LOC does not need to be allocated to host • Static LOC allocation for moving hosts is meaningless • Network based control to support lightweight host • More secure ID structure • Mobile environment is more vulnerable for attack

  4. HINLO Architecture IP address is allocated to network i/f and used as both ID and LOC Internet • IP address is allocated to host itself and ID and LOC is separated • LBS provides the mapping information AN: Access Network AR: Access Router LBS: Location Binding Server HINLO

  5. How to Bind HID and LOC • LBS is responsible for the binding between HID and LOC • Distributed LBS is preferred for scalability • Procedures • HID is informed to AR during attachment • Implicitly or Explicitly • If an AR realizes that a new host is attached, it registers the information (HID:LOC of AR) to LBS by sending LOC Binding Request, on behalf of the host • LBS confirms this binding by replying with a LOC Binding ACK • When the host moves into another AR region, the same procedure will be repeated

  10. Packet Delivery Cost (a) Impact of transmission delay b/w AR and LBS (b) Impact of transmission delay b/w MH and AR

  11. Conclusions • This paper • Identified a set of requirements for mobile oriented ID/LOC split scheme • Proposed the architecture of HINLO that satisfies the requirements • Notable features of HINLO • Allocates LOC to a AR, not a host, whereas a host has only its ID • Can be a incremental approach to allow AN heterogeneity and the use of IPv4/v6 in core • Expected to show much better handover performance than existing ones because of its address-free feature in host • HINLO is being developed as a part of a Korea government funded project on Future Internet • For more information, please visit “www.mofi.re.kr”
