9 Open Fabric SDN The Comprehensive SDN Approach Extreme Networks Open Fabric SDN The Comprehensive Approach to SDN Open Standards The OpenFlow specification provides a clear separation of control and data planes enabling centralized network intelligence Open APIs Programmable interfaces via SOAP and XML enable an application centric network infrastructure Network Overlays Logical and virtual network services using traditional logical separation, technologies, and new innovations such as VXLAN and NVGRE.

10 Comprehensive SDN with OpenFlow Service Enabled OpenFlow OpenFlow Reference Architecture Extreme Networks: OpenFlow with Value Shipping TODAY! 1. Hardware Link Aggregation - EXOS represents the LAG as a single virtual interface to the OpenFlow controller enabling bandwidth scaling, load balancing and link redundancy 2. Hybrid Mode Support - Standard Ethernet switching and OpenFlow based forwarding on a per-vlan basis. 3. Hardware Quality of Service - Configured profile queues are reported to the OpenFlow controller, enabling flows to be programmed directly to hardware queues. 4. Automated Flow Management - EXOS intelligently classifies and maps flows to hardware resources, both the ACL and FDB tables, allowing up to 100,000 flows per switch.

11 Comprehensive SDN with Open APIs and OpenStack XML and SOAP -> OpenStack SOAP Interfaces XML Client Server Messaging Using industry standard messaging protocols allow client and server to exchange configuration, statistics and state information. Available on all Platforms OpenStack is a cloud management and orchestration system that uses API s to provision and manage storage, compute and network resources. Extreme Networks has created a plugin that allows the OpenStack platform to access the network abstraction layer using open API s (SOAP and XML).

12 Comprehensive SDN with Network Overlays Solutions Today Hardware Ready for the Future ISP4 Cust B Cust A Tomorrow VXLAN & NVGRE Currently Available Network Virtualization at Layer 2 with VLANs & L2VPN s with MPLS Network Virtualization at Layer 3 with Virtual Routers (VR) & L3VPN s with MPLS Open API s and OpenFlow can enable applications to create a Network Virtualization Overlay as well see NEC VTN

32 Key SDN Features in EXOS Open vswitch (OVS) based OpenFlow Robust implementation based on OVS Long Term Support (LTS) Advanced Traffic Management Multiple Tables for Deployment Flexibility Multiple VLANs with Edit actions MAC Address Rewrite OpenStack Cloud 32 Orchestration Traffic distributed using LAG hashing Queuing support based on EXOS profiles FDB based flows for simple L2 flows Higher Scale ACL based flows for complex match & set conditions Simple OF based routing between VLANs Support Applications requiring control of multiple VLANs Rewrite source and destination MAC Support L3 SDN applications requiring MAC rewrite Grizzly OpenStack Plug-in for Orchestration Havana Plug-in for Multi-Vendor environments (TBD)

33 Looking to the Future of SDN SDN becomes the Android of networking Open network OS and controller for Ethernet switches and routers OpenFlow and related specifications all available as Open Source Apps for every need From QoS, to PBR, to Identity Management, to Mobility Management, to multi-tenancy and so on Controller vendors eventually become application developers Apps come in free, premium, and freemium models Switch vendors continue to build and sell switches Much like phone vendors continue to sell phones App Stores and Marketplaces for SDN Apps 33

57 SDN Challenges SDN Technology Partners Fast Industry Resource constrained. Channel Partners Identifying Revenue Opportunities Industry view that SDN will lower costs SDN cost savings may be derived from commodity x86 white label switches. Cost savings may be achieved with increased resource utilization, more efficient virtual networking implementations, virtual networking L4-L7 services that replace hardware based L4-7 services Value Proposition in the SDN stack High Performance Networking is a requirement. OpenFlow support a must. X86 won t cut it. New applications (SDN Technology Partners) provide the unique value prop and are key to lowering costs. 57
