The Comprehensive SDN Approach

Open Standards The OpenFlow

specification provides a

clear separation of control

and data planes enabling

centralized network

Network Overlays Logical and virtual network

services using traditional logical

separation, technologies, and

new innovations such as

VXLAN and NVGRE.

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.

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).

Comprehensive SDN with Network Overlays Solutions Today – Hardware Ready for the Future

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

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

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.
