January 30th, 2014
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!

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, …

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

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

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

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 protocols for each layer really required?
IEEE 802.1ah (L2)
IEEE 802.1q (L2)
MPLS (L2.5)
IEEE 802.3 (L2)
IP (L3)
IP (L3)
UDP (L4)
VXLAN(L2)
IEEE 802.3 (L2)
IP(L3)
TCP(L4)
How many layers you say? 5? 7? 11?Err..Who cares?

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.
