=== Introduction ===

'''GNRS(Global Name Resolution Service)'''

In MobilityFirst, there is a clear separation of an end host identifier from its location. The identifier is the GUID(Globally Unique Identifier), while the location is the Network Address(NA). The GNRS is a large scale distributed system that provides mapping between a GUID and corresponding NAs.


'''Inter-Domain Routing'''

Inter-Domain Routing is concerned with determining paths between Autonomous Systems(AS). In the MobilityFirst's Edge-Aware Inter-Domain Routing(EIR), the network elements are aggregated into 'aNodes' connected by 'vLinks'. This aggregation into aNodes allows an AS to control extent of internal structure details advertised.


'''Motivation'''

Consider a stub network moving from one AS to another. Individual updates through the routing protocol will be costly and time consuming. With GNRS assisted routing, a single update to the GNRS would suffice.

This projects aims to explore the feasibility of moving the routing functions into the GNRS.
