www.fp7-federica.eu FEDERICA Vision

• Create by fall 2008 an e-Infrastructure for all researchers on Future Internet. Allow researchers complete control of resources in a “slice”, enabling disruptive experiments.

• Support research in virtualization of e-Infrastructures integrating network resources and nodes capable of virtualization (V-Nodes). In particular on multi(virtual)domain control, management and monitoring, including virtualization services and user oriented control in a federated environment

www.fp7-federica.eu The Enabling Elements1. Virtualization in computing systems and in network is available. It

creates “resources”, given a supporting physical substrate, which :- Have a looser or no dependency from a specific physical location or

entity (computing, data, circuits may migrate)- On-the-fly reconfiguration, cancellation and creation of resources in

the e-Infrastructure (e.g. a routing element, a generic resource)- off-the-shelf components offer in hardware, embedded virtualization

functionalities.2. The European NRENs are managing owned hybrid infrastructures and

actively performing network research, starting from users’ needs. The federated NREN architecture scenario offers now significant interdomainservices and research capabilities.

3. The traditional testbed, focused on a small number of technologies has a usefulness limited to the specialized nature of users. It also implies a long set-up time and a fast obsolescence.

www.fp7-federica.eu FEDERICA e-Infrastructure


www.fp7-federica.eu FEDERICA Principles1. Create an agnostic and neutral (transparent) infrastructure2. Create “slices” which are a set of (virtual) network and computing

resources according to user’s request and are “disruptible”3. Provide to the user complete control within a slice down to the lowest

possible layer (in particular allow any application and protocol)4. Strive/engineer for reproducibility of experiments, i.e. given the same

initial conditions, the results of an experiment are the same5. Allow slices (if requested) to connect to the general Internet, to access

external services/nodes (e.g. for content/delivery, specialized HW)6. Ensure isolation between slices maintaining the possibility to cross-

connect slides on request7. Allow simultaneous use without conflict8. Force/be exposed to topology changes (various level of resiliency)9. Open to interconnect / federate with other e-Infrastructures10. Access granted through a User Policy Board

www.fp7-federica.eu Slicing the Core (Substrate)

FEDERICA substrate

Switches: Juniper MX480, (virtual and logical routing, MPLS, VLANs, IPv4 v6, QoS linecards)

V-Nodes: Up to 8-16 images/node, Unix OS, 4-8 Ethernet NICs, ~ 1 TB disk, 4core CPUs


www.fp7-federica.eu Access and Use Policies

• A User Policy Board will receive and approve project for the use of the infrastructure

• Access to the infrastructure is subject to the signature of an “Acceptable User Policy”, which includes providing feedback

• Usage of a FEDERICA slice will be free of charge if no additional equipment is requested

• Interconnection with other infrastructures (e.g. labs) is possible. The cost is to be defined case by case.

• The time duration of a single experiment will be in principle limited to facilitate turnover (3 months initially)

• Access is open to research groups from academia and private sectorwith priority to European Community funded projects.

• The code and tool bench produced will be Open Source

Users’ requirements are fundamental and are being collected


www.fp7-federica.eu

Federating and Interconnection with other projects/groups

• “Soft” model– Act as a user of the project (hosting its virtual resources with

possible interconnection to external resources using Internet)– Collaboration at the project/user group level to exchange

intermediate results, perform joint developments

• “Hard” model– Hosting in FEDERICA a physical resource – Interconnecting the testbeds using a dedicated network resource

Need for a resource/service description format (e.g. TMF, IPSphere, …)


www.fp7-federica.eu FEDERICA - Goals Summary—Provide on European scale network and system agnostic e-Infrastructure

to be deployed in phases for Future Internet research (and not only). Provide its operation, maintenance and on-demand configuration

—Act as a forum and support for researchers/projects on “Future Internet”. Support of experimental activities to validate theoretical concepts, scenarios, architectures, control and management solutions. Users have full control of their slice

—Validate and gather experimental information for the next generation of research networking also through basic tool validation

—Dissemination and cooperation between NRENs and researchers’community

—Contribution to standards in form of requirements and experience

Inscope

—Internal extended research, e.g. advanced optical technology—Development of Grid applications (but open to hosting)—Offer raw computing power—Offer transit capacity

Out ofscope


www.fp7-federica.eu Initial Boundaries

• Equipment hosting, federation with other testbed

• Not all technologies available (e.g. wireless, nomadic nodes)

• Slower initial provisioning, compatible with decision process and overall management• Initial manual provisioning

• Rely more on software emulation• Less powerful switches outside the core

• Hardware QoS is available on two Juniper MX480 switches

• Packet switching and statistical multiplexing assumed by default

• Not considered a limiting factor, can be overcame later using WDM equipment

• Ethernet framing (large MTUs) as data link

• Equipment is ready for IPv6• IPv6 unconfigured, to be enabled according to users’ requests

• Larger virtual slices can be obtained reducing the number of concurrent users, user’s equip. may be added

• Scalability


www.fp7-federica.eu

Control Plane and Virtualization:an additional challenge…

- The main control plane is now tied to the “basic substrate”, its main and new function is to create “slices” made of “resources”. It implies the need to define:- user interface specification for request (UNI-type, but UNIs do not

have currently the required parameters) - resources abstraction and specification (network part ongoing in GN2

(AutoBAHN) and international collaboration with I2, ESnet)- signalling protocols for UNI communication- Interdomain communication specification

- Need to manage the basic substrate and one or more slices at the same time:- Control plane extensions in the layered framework- control plane capable of communication with one or more”hosted”

control planes


www.fp7-federica.eu C.P. and Virtualization (cont)…

- Extension and definitions for naming, addressing, to allow the possibility of global reachability

- Monitoring interaction,synergy between the substrate and the slices in sharing the physical elements

FEDERICA will start with manual provisioning of virtual resources, a single IP AS and public IP network addresses for the substrate.

Overall neither the integrated model, nor the layered one may be adequate and further advances are required in HW and SW to allowvirtualization capabilities with resource assurances.

BUT …


www.fp7-federica.eu THE challenge: Complexity

The major risk is to create a system which is too complex.

L’acronimo GARR deriva da

“Gruppo per l’Armonizzazione delle Reti della Ricerca”.

Il Gruppo si e’ autocostituito nel 1987 per permettere una sinergia delle comunitàscientifica delle Università e degli Enti Pubblici di Ricerca italiani nella realizzazione, gestione, ricerca e utilizzazione delle reti di interconnesione, analogamente alle Reti della Ricerca e dell’Istruzione già esistenti in altri paesi.Nel 1989 Il GARR si costituisce formalmente grazie ad un progetto finalizzato del MURSTNel 2002 nasce l’Associazione senza fini di lucro “Consortium GARR”, essendo CNR, CRUI, ENEA ed INFN i membri fondatoriIl mandato principale del Consortium GARR e’ di gestire e sviluppare la rete della ricerca e dell’istruzione italiana.
