Outline
• FIA Vision
• Future Internet Architecture (FIA) Projects
• FIA Projects’ Current Ideas about Using GENI
• Going Forward—What might be next for FIA &
GENI?
2
Future Internet – The Vision
• Society’s needs for an IT infrastructure may no longer be met
by the present trajectory of incremental changes to the
current Internet
• Society needs the research community to create the
trustworthy Future Internets that meet the needs and
challenges of the 21st Century.
• Research should include intellectually distinctive ideas,
driven by the requirement for long-range concepts unfettered
by the current limitations of or the requirement for immediate
application to the current Internet. Architecture includes all
needed functionalities (overarching architecture).
• Research on Future Internets create a community better
informed and educated about network architecture design

Future Internet Architectures (FIA)
NSF issued a call for proposals:
• To support innovative and creative projects that
conceive, design, and evaluate trustworthy
Future Internet architectures
• 4 projects awarded – A diverse portfolio
– (smaller projects under consideration and expected
submit to NeTS Large)
• http://www.nets-fia.net/

FIA Projects and their View of the Future
• Mobility First
– The future is mobile (Cellular, wireless sensors, machineto-machine, smart grid & vehicular nets integrate physical
world awareness and control into Internet applications)
• NEBULA
– 24x7 Utility for secure communication, computation and
storage
• Named Data Network (NDN)
– Content is the future driver
• eXpressive Internet Architecture (XIA)
– Design for evolution of: usage (host-host, content retrieval,
services) and technology (link, storage, computing)

MobilityFirst
• Principle Investigator: Dipankar Raychaudhuri, Rutgers
– Collaborating Institutions: Duke Univ., Massachusetts
Institute of Technology, Univ. of Massachusetts/Amherst,
Univ. of Massachusetts/Lowell, Univ. of Michigan, Univ. of
Nebraska/Lincoln, Univ. of North Carolina/Chapel Hill, Univ.
of Wisconsin/Madison
• Underlying architectural principles
– Mobility is the norm without gateways or overlay
accommodations
– The architecture uses generalized delay-tolerant networking
(GDTN) to provide robustness even in presence of
link/network disconnections. GDTN integrated with the use
of self-certifying public key addresses to provide an
inherently trustworthy network. Wired networks special case.

Named Data Networking
Principle Investigator: Lixia Zhang, UCLA
– Collaborating Institutions: Colorado State University, PARC, Univ.
of Arizona, Univ. of Illinois/Urbana-Champaign, UC Irvine, Univ. of
Memphis, UC San Diego, Washington Univ., and Yale Univ.
Underlying architectural principles
• Content is what users and applications care about; By naming data
not location data become a first-class entity.
• Underlying architectural principles
– Packets indicate what (content) , not who/where (IP address)
– Packet is a <name, data, signature>
• Securing named data potentially allows trust to be more user-centric.
– Retain the hourglass in the architecture
– Separate routing and forwarding

Named Data Networking (NDN)
♢
The architecture retains the hourglass shape
♢ Change the thin waist from using IP addresses
to using data names



♢
♢
Always retrieve data from closest copy on a path to
source; use memory for intrinsic multicast
distribution
IP addresses name locations; retrieving data by
names eliminates a fundamental hurdle in mobility
support
Retrieving data by names facilitates new
application development in sensor networking
Robust security from per packet signature
The new strategy layer enables intelligent data
delivery via broadcast, multicast, and multiple
paths

NEBULA
• Principle Investigator: Jonathan Smith, Univ. of Penn.
– Collaborating Institutions: Cornell Univ., Massachusetts Institute of Technology,
Princeton Univ., Purdue Univ., Stanford Univ., Stevens Institute of Technology,
Univ. of California/Berkley, Univ. of Delaware, Univ. of Illinois/UrbanaChampaign, Univ. of Texas, Univ. of Washington
• Underlying architectural principles
– Always-on utility where cloud computing data centers are the primary
repositories of data and the primary locus of computation
– Storage, computation, and applications move into the "cloud“
– Data centers are connected by a high-speed, extremely reliable and
secure backbone network.
– Parallel paths between data center and core
– Secure access and transit, policy-based path selection and
authentication during connection establishment

eXpressive Internet Architecture (XIA)
• Principle Investigator: Peter Steenkiste, Carnegie Mellon
Univ.
– Collaborating Institutions: Boston Univ., Univ. of
Wisconsin/Madison
• Underlying architectural principles
– XIA offers support for communication between current
communicating principals--including hosts, content, and services-while accommodating unknown future principals.
– For each type of principal, XIA defines a narrow waist that dictates
the application programming interface (API) for communication and
the network communication mechanisms.
– XIA enables flexible context-dependent mechanisms for
establishing trust between the communicating principals.

XIA Components and Interactions

FIA Projects’ Current Ideas to use GENI
Project:
• Just began September 1, 2010;
• Are at different levels of maturity; as are
• Their plans for experimentation and how
they might use GENI.
14
Potential use of GENI in NEBULA*
• GENI Technology:
-
Enables experiments involving multiple sites
Isolates NEBULA experiments to a single VLAN
Eliminates need for special HW & Address Translation
• Potential Uses:
-
Multisite student collaboration on Ncore (NEBULA Core)
Testbed for NDP (NEBULA Data Plane) experiments
Platform for NVENT (NEBULA extensible control plane)
* No GENI-enabled switches on NEBULA campuses-->so preliminary
thoughts
15
15
XIA Testbed Requirements
• Run fairly large, geographically diverse experiments
– Several tens or more nodes
• High speed packet processing platform
– Evaluating Openflow – XIA is very different from IP
• Diverse access network technologies
– Evaluate XIA over diverse networks using
applications
• Short learning curve for students
– Avoid time sink that takes away time from research
– Essential for UG and MS student participation
