The document discusses the rise of network virtualization and software-defined networking (SDN). It describes early research projects on campus networks like Ethane in 2007 that led to the OpenFlow specification in 2008. This allowed experiments with new network protocols. The document outlines the founding of Nicira in 2007 and the company's product launch of the Network Virtualization Platform in 2012, which used SDN to virtualize networks.

7. Why?
The Need of New Network Architecture
 Changing Traffic Patterns
 Consumerization of IT
 Rise of Cloud Service
 “Big Data” means more bandwidth

8. Why?
Limitations of Current Networking Technologies
 Complexity leads to inactivity
 Inconsistent policies
 Inability to scale
 Vendor dependence

10. The Beginning (2007)
Faster networks but not better networks
Innovation in other areas
 OS: file systems, schedulers, virtualization
 DS: DHTs, CDNs, MapReduce
Networks are largely the same
as years ago
 Ethernet, IP, WiFi
10

11. Ethane
 PhD project in Stanford
 Allow managers to define single network-wide
fine-grain policy
Principles
 Network policies declared over high-level names
 Policy determines path
 Strong binding between a packet and its origin

16. Ethane
Performance and Scalability
Execute Ethane in campus network
Extrapolate result for bigger network
Controller able to handle up to 20k hosts
Latencies ≈ RTT between hosts
in diff. subnets in campus network

18. The Specification(2008)
OpenFlow
 The whitepaper inspired by Ethane
 Developed in Stanford as well
 Evolve into Open Networking Foundation
 Problem statement: No practical way of
experiment with new network protocols. How we
can run experiments in Campus Networks?

19. OpenFlow
Switch feature that can help extend
programmability into wiring closet of college
campuses

26. The Product
Network Virtualization Platform (NVP)
 “The Matrix”
 Allow to reprogram the network used by
programs or applications
 More reliable internet
 Move like a “liquid” between data centers
