Virtualization

Creation of virtual version of …

Hardware components, storage, network.. etc

3

Network Virtualization

Virtualization of Network Resources, e.g:

VLAN = Virtual LAN

4

Network Virtualization

Virtualization of Network Resources, e.g:

Overlay

5

Network Virtualization

Virtualization of Network Resources, e.g:

Software Defined Networking (SDN)

6

SDN

SDN is new approaches of networking with..

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

Timeline

2007: The beginning

2012: The product

2008: The specification

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

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

12

Ethane

Communication flow

13

Ethane

Deployment

14

Ethane

Controller

15

Ethane

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

20

Open Flow

Network of OpenFlow switches
