1 THE REVOLUTION TOWARDS SOFTWARE- DEFINED NETWORKING Transforming Networking with Open SDN Guido Appenzeller April, 2013

2 JOIN THE REVOLUTION TOWARDS OPEN NETWORKING Independence from closed, proprietary systems Freedom of choice in vendors Power of centralized network control 2013 BIG SWITCH NETWORKS, INC. 2

3 CLOSED & PROPRIETARY NETWORKING EQUIPMENT VerNcally Integrated Systems Have Changed LiQle Over the Past 15 Years Feature 1 Feature 2 Provisioning and Management StaNc, manual configuranon Low feature velocity Proprietary Network OS OperaLng Systems Few API s, only CLI (closed OS) Not externally programmable Proprietary System Hardware Systems Lock- in to a parncular vendor Proprietary Silicon System Silicon Slow innovanon cycles Expensive, no economies of scale 2013 BIG SWITCH NETWORKS, INC. 3
