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.

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!

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, …

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

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

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

Are all these

really required?

How many layers
you say? 5? 7? 11?
Err..
Who cares?

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.
