1 NOVI: Networking innovations Over Virtualized Infrastructures STREP Project No. 257867, Call 5 – FIRE NOVI OVERVIEW Prof. Vasilis Maglaris (NETMODE/NTUA) Dr. Chrysa Papagianni (NETMODE/NTUA) GENI Engineering Conference – GEC 18 Brooklyn, New York, October 2013

2 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.

5 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.

6 NOVI – Information Model

7 The NOVI Information Model Background

8 NOVI Control & Management Architecture

9 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 (

10 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

11 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

12 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

13 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

18 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

19 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…) 19
