SDN in the Data Center: Programmatic Control50% reduction in SDN deployment cost


• Concurrent network control by SDN controller and traditional control plane

• Optional “protection” layer between both modes

• Enabled by Brocade’s“Hybrid mode”

• Reuses infrastructure for both SDN and traditional control plane

OpenFlow Feature overview

© 2014 Brocade Communications Systems, Inc. Company Proprietary Information 7

• OpenFlow v1.3 is not backward compatible with OpenFlow 1.0• Greater flexibility with OpenFlow v1.3• Watch out for the details

Example: Volumetric traffic managementEfficient and scalable

• Real-time detection of large flowsvia sFlow-RT (Real-Time)

• Collector programs controller to apply appropriate treatment of flow

• Brocade value:‒Capability integrated into router with

OpenFlow hybrid mode

‒High-performance flow management

• Benefits:‒Mitigation at border relieves rest of DC

‒Programmatic closed-loop control

‒Limits investment in expensive appliances

Software Defined Networkingusing OpenDaylight Controller


A New Network ArchitectureSoftware Defined Networking Logically Centralizes the Control Plane

• EMS, NMS, CLI and APIs specific to the switch or router vendor

• Proprietary control plane per device

• Communication protocols standardized for interoperability

Cloud Orchestration — OpenStackOpen source management framework for clouds

• Open source cloud management framework for private and public clouds

• Created by Rackspace and NASA in July 2010

• Capturing the hearts and minds of the industry

‒ Rapidly becoming the de facto open source standard for cloud computing

‒ ~200 participants and 6,000+ developers

‒ Allows any organization to create and offer cloud computing capabilities using open source software, rapidly and at a low cost

Brocade and OpenStackSelf-service, on-demand provisioning

• Brocade product line support in OpenStack orchestration dramatically decreases time-to-deploy network capacity

• Brocade leading industry efforts to champion:

‒ OpenStack support of Fibre Channel SAN Zoning in the Cinder project

‒ Dynamic Network Resource Management (DNRM) extensions to Neutron project

• Partnering with Red Hat, Rackspace and Piston Cloud for commercial distros of OpenStack

Summary


The benefits of OPEN

• Remember Linux in the 90‘s

• The OPEN networking projects are at varying degrees of maturity

• First use-cases and solutions are already in production

• Eventually, this will be the disruptive standard for agile and flexible network architectures supporting the New IP

• NOW is the time, to shape a strategic OPEN mind settowards the future proof infrastructure of tomorrow
