The PRISTINE project proposes a new approach to SDN using RINA as its foundation. The project aims to build a RINA SDK to allow experimentation with SDN in a way that addresses the limitations of current SDN approaches. It will develop RINA management systems and policies to create optimized DIFs for use cases like distributed cloud, datacenter networking, and network service providers. The goal is to leverage RINA's ability to maximize invariants and simplify protocols to provide programmability benefits for SDN.
Pristine Intro SDN Concertation Workshop
- 1. PRISTINE Project A different approach to SDN Joan A. García-Espín Area Director Distributed Apps and Nets January 30th, 2014 RINA Research, Korea-EU Workshop
- 2. Primary Goals of SDN 1. Commoditization of network equipment 2. Programmability What for? • Flexibility, agility, re-use and automation • Seamless integration with infra. management solutions • … and lowering CAPEX and OPEX! SDN Concertation Workshop January 30th, 2014 1
- 3. Generic Scenario App. MW or Orchestrator Northbound interface Controller Southbound interface (Openflow or other) SDN Concertation Workshop January 30th, 2014 Northbound interface East/West interface App. MW or Orchestrator Controller Southbound interface (Openflow or other) 2
- 4. Inconveniences • Commoditization: Who decides what is the minimum? • Programmability: Only for the forwarding table? – What about data transfer, flow control, resource allocation, authentication, access control, enrolment, … • Complexity: Still based on TCP/IP? – Tons of RFCs, security, multi-homing, mobility, … SDN Concertation Workshop January 30th, 2014 3

- 7. RINA and SDN Goals, how? • Commoditization: – RINA defines the common elements in computer networking • Programmability: – RINA defines the variable behaviour for common elements, and hence common APIs to program them • Complexity: – RINA maximizes the invariants, hence requires far less protocols to provide computer networking SDN Concertation Workshop January 30th, 2014 6
- 8. PRISTINE at a glance • Design a RINA SDK • Design and implement a RINA management system (multi-layer) • Implement trial policies to create optimized DIFs: distributed cloud, DC networking and NSP SDN Concertation Workshop January 30th, 2014 External Advisory Board Cisco Systems, Telecom Italia, Deutsche Telekom, Colt Telecom, Boston Univesity, Interoute 7
- 9. PRISTINE and RINA Roadmap • Research on policies for different areas: – Congestion control, distributed resource allocation, addressing, routing, authentication, access control, encryption, DIF management • Prototype and Test: – Implementation leveraging IRATI for Linux OS. – Develop SDK, Policies and DIF-MS • Experiment: – Complex deployments, coexisting technologies at once (IPv4, IPv6, Ethernet), business applications SDN Concertation Workshop January 30th, 2014 8

- 11. Summary • SDN is not only OpenFlow and controllers • RINA offers a new playground for SDN • PRISTINE project just started, to build RINA SDK for you to experiment SDN in a different way SDN Concertation Workshop January 30th, 2014 10
- 12. Moltes gràcies! Thank you! Joan A. García-Espín jage@i2cat.net @joanange
- 13. Bottomline TCP(L4) IP(L3) IEEE 802.3 (L2) Are all these protocols for each layer really required? VXLAN(L2) UDP (L4) IP (L3) IP (L3) IEEE 802.3 (L2) MPLS (L2.5) IEEE 802.1q (L2) How many layers you say? 5? 7? 11? Err.. Who cares? IEEE 802.1ah (L2) Thanks we have RINA!

- 15. PRISTINE Use Cases • Distributed cloud – Decentralized cloud technology; customer’s applications run in DCs but also in servers from offices and home users. – Infrastructure interconnected through multiple ISPs, overall connectivity provided through overlay on top -> Use RINA to provide this overlay • Datacentre networking – Evaluate RINA as a technology that allows more dynamicity and tighter integration with applications (dynamic instantiation of application-optimized VPNs) • Network Service Provider – Investigate benefits of RINA for NSP: better network design, simpler management, DIFs that support different levels of QoS with stronger flow isolation, better security, programmability, etc. SDN Concertation Workshop January 30th, 2014 14
