FEDERICA Vision
WWW.FP7-FEDERICA.EU
An e-Infrastructure based on virtualization in both computers
and network is a fundamental tool for researchers on Future
(and current) Internet.
The facility should allow researchers a complete control of their
set of resources in a “slice”, enabling disruptive experiments at
all communication layers.
Particular care should be placed in reproducibility of the
experiments and in the avoidance of complexity.
Such e-Infrastructure can be built on existing infrastructures
using a practical approach and should be able to “federate” with
other facilities.

Pictorial of creation of a Slice
WWW.FP7-FEDERICA.EU
The user requests an Infrastructure made of L2 circuits, un-configured
virtual nodes, to test a new BGP version. Creation of:
1. user credentials and authentication and a “Slice”
2. Virtual Gateway (in red) to bridge the user from outside into the slice
3. Create resources and connect them as specified by the user

Offering “Slices” for “any” Research
WWW.FP7-FEDERICA.EU
Using Virtualization technologies the FEDERICA e-Infrastructure
creates “slices” composed by virtual resources (circuits, nodes,
routers)
The slices are configured
according to users’
requests
Possible use cases:
- new routing protocols
- behavior on the network
of distributed
applications
Global Internet
- Inter-domain
services

The User Policy Board tasks
WWW.FP7-FEDERICA.EU
- First contact point for users:
- advises and clarifies initial questions and points to /
clarifies issues in the compilation of the requested
documents (User Information kit)
- Receives the official requests from users and evaluates
technically (not scientifically !) the proposals (with the support
of technical experts)
- Ensures the implementation of slices according to agreed
schedule
- Follows a user with a dedicated FEDERICA person through
the user project lifetime
- Receives user feedback

Users
WWW.FP7-FEDERICA.EU
The project had its launch event end of November 2008.
We have the current users / projects ongoing approved:
- Onelab and monitoring testing (ELTE Hungary)
- Openflow tests (Stanford, Germany, Sweden, Italy)
- Monitoring (Czech Rep. - Internal)
- PHOSPHORUS project
Pending requests from Ireland, Italy, Spain, Germany
Many requests for interconnection capabilities between initiatives and
laboratories and some requests for optical testing

Federating FEDERICA
WWW.FP7-FEDERICA.EU
We should differentiate between various forms of federation:
1. integrated ( the facilities can be used as one with a
inter-domain common control plane)
2. partially integrated (only part of the control is
exchanged, e.g. calendar, AAA information)
3. overlay (each facility just uses the services of the other
without a common control plane, just a data plane,
there is an exchange of information related to
monitoring, faults, and so on)
All these possibilities present challenges …

FEDERICA Data and Control Plane
WWW.FP7-FEDERICA.EU
Access protocol : initially paper due to need for scheduling, security
and technical agreements (no first come, first serve policy). Next step
may be based on SOA (need standard representation of resources)
Control plane is not fully automated and it is a set of tools and manual
configuration (due to the combined network and system resources)

Federating FEDERICA (cont)
WWW.FP7-FEDERICA.EU
Having a common control plane in a multidomain environment is
very difficult, as it places many constraints to each facility (in
time, technology and developments).
Need to develop standard resources representation schemas for
virtual resources and virtual resource sets to exchange services.
The inter-facility exchange of information and synchronization
between facilities has to scale gracefully.
The Intra-facility control plane is complex, due to resource
scheduling and resources mapping from virtual topology (slice) to
physical topology, especially if reproducibility or guarantees are
mandated.

FEDERICA - Onelab2 pre-federation
WWW.FP7-FEDERICA.EU
OneLab nodes can be hosted in a slice. Those node have full
control of their network interface and circuits up to the egress
from FEDERICA into General Internet. The slice can contain
also a “OneLab router”

Conclusions
WWW.FP7-FEDERICA.EU
An infrastructure based on virtualization, network and
computing resources can offer a very useful platform for
innovation and research at many (if not all) communication
layers and can be realized on existing facilities.
The physical resources functionalities and infrastructure
engineering should ensure the functionality to guarantee the
“quality” of the virtualization for reproducibility.
Federation is of outmost importance (e.g. to access new
technologies and to ensure a larger facility), but has many
facets and complexities. A practical approach through a
“supportive” or “pre-federation” is advised.
