MobilityFirst Future Internet Architecture Project

by , under Uncategorized

The Internet is approaching an historic inflection point, with mobile platforms and applications poised to replace the fixed-host/server model that has dominated the Internet since its inception.

The major design goals of our proposed architecture are: mobility as the norm with dynamic host and network mobility at scale; robustness with respect to intrinsic properties of wireless medium; trustworthiness in the form of enhanced security and privacy for both mobile networks and wired infrastructure; usability features such as support for context-aware pervasive mobile services, evolvable network services, manageability and economic viability. The design is also informed by technology factors such as radio spectrum scarcity, wired bandwidth abundance, continuing Moore’s law improvements to computing, and energy constraints in mobile and sensor devices.



The key components of the MobilityFirst network architecture are: (1) separation of naming and addressing, implemented via a fast global dynamic name resolution service; (2) self-certifying public key network addresses to support strong authentication and security; (3) generalized delay-tolerant routing with in-network storage for packets in transit; (4) flat-label internetwork routing with public key addresses; (5) hop-by-hop transport protocols operating over path segments rather than an end-end path; (6) a separate network management plane that provides enhanced visibility; (7) optional privacy features for user and location data; and (8) an integrated computing and storage layer at routers to support programmability and evolution of enhanced network services.
