What: European Community co-funded project in its 7th Framework Program in the area “Capacities - Research Infrastructures”, 3.7 MEuro EC contribution, 461 PMs

When: 1st January 2008 - 30 June 2010 (30 months)

Who: 20 partners, based on stakeholders on network research and management: 11 National Research and Education Networks, DANTE (GÉANT2), TERENA, 4 Universities, Juniper Networks, 1 small enterprise (MARTEL), 1 research centre (i2CAT) - Coordinator: GARR (Italian NREN)

Where: Europe-wide e-Infrastructure, open to external connections


WWW.FP7-FEDERICA.EUFEDERICA Vision

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.

Switch: Juniper MX480, Dual CPU, 1 line card with 32 ports at 1Gb Ethernet. Virtual and logical routing, MPLS, VLANs, IPv4, IPv6, 2 of the 4 line cards have hardware QoS capabilities)

V-Nodes: each is a 2 x Quad core AMD @ 2GHz, 32GB RAM, 8 network interfaces, 2x500GB disks, Virtualization SW

FEDERICA substrate


WWW.FP7-FEDERICA.EUThe Core Substrate - IP

Management plane defined as an IP Autonomous System:

AS: 47630 (public, no transit, peers with GARR, PSNC which announce the AS to GN2 and General Internet) active

IP v4 : 194.132.52.0/23 (public addresses) active

IP v6 : 2001:760:3801::/48 (public) (to be configured soon)

WWW.FP7-FEDERICA.EUPictorial of creation of a SliceThe 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

FEDERICA substrate (only CORE is shown)



WWW.FP7-FEDERICA.EUOffering “Slices” for “any” Research

Using Virtualization technologies the FEDERICA e-Infrastructure creates “slices” composed by virtual resources (circuits, nodes, routers)

FEDERICA substrate (only core is shown)

Global Internet

The slices are configured according to users’ requests

Possible use cases:

- new routing protocols

- behavior on the network of distributed applications

- Inter-domain services

WWW.FP7-FEDERICA.EUThe User Policy Board tasks- 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


WWW.FP7-FEDERICA.EUUsers

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


WWW.FP7-FEDERICA.EUFederating FEDERICA

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 …

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)

WWW.FP7-FEDERICA.EUFederating FEDERICA (cont)

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 substrate


Onelab Slice

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”


WWW.FP7-FEDERICA.EUConclusions

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.
