2 Agenda Software Defined Networking Technologies SDN Use Cases OpenFlow Network Function Virtualization Orchestration 2014 Brocade Communications Systems, Inc. - Company Proprietary Information 3

3 Software Defined Networking Technologies Functional Definitions 2014 Brocade Communications Systems, Inc. - Company Proprietary Information 4

4 Software Defined Networking 3 Areas SOFTWARE NETWORKING TECHNOLOGIES OpenFlow Separation of control and data plane Control Plane agnostic to the underlying hardware Network Programmability Hardware in Software (NfV) Virtualization of networking components Commodity hardware x86 Cost, flexibility, agility Integration with higher-order Orchestration platforms OpenStack, CloudStack, vcloud Director API interaction with network elements Vendor Independence 2014 Brocade Communications Systems, Inc. - Company Proprietary Information 5

5 Programmatic Control OpenFlow A NEW POINT OF INNOVATION FOR NETWORK FUNCTIONALITY Features Device OS Hardware Customer/Vendor/Partner Applications Network Controller The biggest innovation since Ethernet: OpenFlow from distributed to centralized Control Plane allows dramatic reduction in complexity due to End-to-End topology knowledge Applications OS Hardware Applications Applications OS Hardware OS Hardware OS OS Hardware OS Hardware VCS further reduces management complexity OS Hardware Hardware Traditional Network OpenFlow based Network 2014 Brocade Communications Systems, Inc. - Company Proprietary Information 6

6 Network Functions Virtualization A COMPOUND DISRUPTION Virtual machine-based or Bare Metal Leverages server performance Open systems Automation (Templates) Virtualizing the networking components as a Service Routing, Firewall/Security, Load-balancer Cloud Service Provider model Motivation for Telcos (SP) to move to the CSP model 2014 Brocade Communications Systems, Inc. - Company Proprietary Information 7

7 Overlay and Underlay SOFTWARE NETWORKING TECHNOLOGIES An Overlay is a virtual network built on top of an underlying network infrastructure (the Underlay) Overlays are defined by the NVO3 Working Group Guarantees traffic segregation for users (tenants) Allows dynamic placement of end stations (/Servers) and does so independently of the underlay Supports address space independent of the tenants Current Overlay Protocols VXLAN NVGRE STT 2014 Brocade Communications Systems, Inc. - Company Proprietary Information 8

8 Orchestration Layer SOFTWARE NETWORKING TECHNOLOGIES Orchestration is a control layer above the available networking resources that allows for centralized control Openstack, Is aware of all networking resources. Another layer of control (e.g. DNRM) Uses overlay and control language like Openflow to manipulate, monitor and control Northbound API for higher level control Southbound control neutron Orchestration layer Openstack Cloudstack 2014 Brocade Communications Systems, Inc. - Company Proprietary Information 9
