NOVI’s Objectives
• NOVI targets innovative research in a bottom-up approach,
addressing a critical area in FI services: How FI users securely
share a multi-domain networking substrate.
• NOVI builds a set of algorithms, methods and services for
control and management of federated virtualized
infrastructures.
•
Provide experimenters the ability to request, reserve, use and
update a basket of virtualized resources in a federated
environment, tailored to their needs.

NOVI’s Technical Approach
• Design and implement a modular data, control and
management plane architecture as an integrated prototype
implementing:
– An ontology-based Information Model capturing the abstractions of virtualized
resources and services across different platforms.
– A framework providing interoperability of monitoring tools across federated
heterogeneous platforms.
– A semantic distributed resource discovery and mapping framework tackling the
inter-domain virtual network embedding problem.
– A policy-based management framework able to enforce intra and inter-domain
management policies.
– Data-plane stitching mechanisms towards transparent data-plane connectivity
across dissimilar platforms involved in multi-domain user-slices.
NOVI – Information Model
The NOVI Information Model
Background
NOVI Control & Management
Architecture
NOVI External Components
• Build on top of Slice Federation Architecture – SFA
– FEDERICA adapter
1. Acts like an Aggregate Manager
2. Acts as the C&M plane for FEDERICA
3. Extended RSpec ProtoGENI v2
• Prompted the development
of the Generic SFA Wrapper
by NOVI partners
(http://sfawrap.info/)
Innovative NOVI Services (1/4)
• NOVI API
– Exposes services provided by NOVI service layer e.g. combined slice
creation, slice deletion, resource cross-listing
– Feedback component: captures interactively how a user request is
being handled within NOVI service layer
• Request Handler
– Invokes appropriate operations to the corresponding SFA APIs
o Handles resource provisioning requests to the underlying platforms
o Enables information retrieval from test beds
o Translates NOVI IM to PlanetLab/FFEDERICA RSpec and vice versa.
– Triggers calls to the NSwitch service
Innovative NOVI Services (2/4)
• NSwitch Service
– Provides L2 connectivity between resources of the same slice residing
in different domains: PlanetLab (slivers) and FEDERICA (Logical
Routers)
– Ethernet over GRE traffic originating from PlanetLab slivers is
translated to FEDERICA VLAN tagged traffic via the NOVI NSwitch
• Resource Information Service (RIS)
– Responsible for collecting information about available resources
across the federation and providing it to other NOVI services.
– Maintains information about slices, users and policies
– Resource discovery/ registration /reservation
Innovative NOVI Services (3/4)
• Monitoring Service
– Handles the available monitoring tools in a uniform way
– Harmonizes the measurement data that the tools provide
– Triggers substrate / slice passive or active monitoring
– Slice Monitoring API
• View instantiated slices via Platform specific GUIs
• Keep track of monitoring information
• Submit slice monitoring tasks into the NOVI federated testbeds
Innovative NOVI Services (4/4)
• Policy Service
– Policy based management system / Ponder2 policy framework.
– Policies
o Intra-domain (Access Control, Event-Condition-Action, Role Based Access
Control - RBAC)
o Inter-domain (Mission).
• Intelligent Resource Mapping Service
– Orchestrates the creation of a new combined slice
– Combined Slice Embedding; decides upon the strategy for dealing
with the various sub-problems of the mapping process (Multi-domain
Virtual Network Embedding)
– Facilitates slice re-embedding e.g., upon node failure

Need for Federated FI Testbeds: The
NOVI Experience
• Validation of NOVI innovative services over small scale
representative stitched testbeds
– FEDERICA: controlled virtualized environment (networking and
computing resources) - modeling a private virtualized Data Center
(IaaS) with commercial middleware (VMware ESXi, Juniper Junos)
– Private PlanetLab installations - modeling public cloud PaaS.
• NOVI relied on wide area networking resources (L2/L3
connectivity) and expertise from NRENs and GÉANT
• NOVI faced complex SW engineering issues for delivering a
stable distributed approach
– Building upon GENI and FIRE basic services
18
Lessons Learned
• Greatest challenge: to orchestrate a multi-national,
multi-faceted consortium towards delivery of
innovative FI services as stable proofs of concept
• The NOVI consortium combined:
–
–
–
–
Academic excellence (Universities &Research Centers)
SW development skills (Laboratories active in FI R&D)
Operational experience (NRENs)
Industrial insight of a major vendor (Cisco)
• NOVI profited from strong links with the global FI
community (FIRE, GENI, NRENs, GÉANT, Internet2…)
