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

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

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

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

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
