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

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
