Extreme Networks was established by co-founders Gordon Stitt, Herb Schneider and Stephen Haddock in 1996 in California, USA, with its first offices located in Cupertino, which later moved to Santa Clara. Extreme Networks’ mission was and is to deliver high performance, Layer 3 IP/Ethernet networking technology, including Quality of Service and resiliency, with the scale and speed of emerging Gigabit Ethernet switching.
Its products were targeted at corporate enterprises and companies building and hosting the emerging broadband Internet. Extreme Networks launched its Initial Public Offering in April 1999, listed on the Nasdaq, as ticker ‘EXTR’. Extreme Networks’ first shipping product was the Summit1 gigabit switch, a 6 Port Ethernet Layer 3 switching device featuring 1000SX Dual GBIC SX interfaces. This product shipped in 1997 and won the ‘Best of Show’ award at the Networld+Interop industry tradeshow event in 1997. The Summit1was also named the ‘Best of the Best Grand Winner’ for the event. Extreme Networks won Best of Show awards at Networld+Interop five consecutive years, 1997 through 2001. Extreme Networks introduced its first modular switching products, including the BlackDiamond 8800 and Alpine 6800 switches, in 1999. Extreme Networks launched its first standards-based 10 Gigabit Ethernet solution in 2002, available with its BlackDiamond 6800 switch. Extreme Networks adopted an extensible, modular software Operating System (OS) for its switching products beginning in 2003, where a Linux abstraction layer was featured and debuted with its BlackDiamond 10K switch. The ExtremeXOS software OS was later expanded with its Summit line of fixed switches and the BlackDiamond 8800 family of modular products. Extreme Networks’ most recent high capacity switch is the BlackDiamond 20808, supporting 120 Gigabits per line card, and is purpose built for Carrier Ethernet networks, providing economical Metro transport.
Scalable and Agile Solutions for Data centres, Cloud Computing and hosted environments. Enterprises and hosting companies alike rely on data centres to host essential business applications; universities and healthcare facilities rely on data centres to provide access to critical information and applications; and content owners rely on data centres to host and scale access to content. The data centre is required to offer high-performance and agile responses to the ever-growing demands of the applications and storage they support. The underlying switching infrastructure must have the intelligence to address security and resiliency issues, but do so with simple and efficient solutions. In addition to each of these demands, the switching infrastructure must be cost effective and energy efficient.
The Data Centre is the lifeline of the business today. Downtime in the Data Centre simply means that business stops, leading to lost productivity, lost revenue and increased customer dissatisfaction. With resiliency only as good as the weakest link, key to a 24×7 Data Centre is an investment in network infrastructure that is robust at every level – hardware, software and network. Comprehensive high-availability capabilities are central to Extreme Networks solution spanning resilient hardware, modular software, and leading protection switching features, enabling a highly available network infrastructure. Extreme Networks gigabit and 10 Gigabit Ethernet (GbE) top of rack, end of row and core switches provide agile network infrastructure solutions to keep ahead of the growing bandwidth demands in data centre networks. The Summit® X650 switch helps optimise new server deployments while providing a seamless migration path from existing gigabit to 10 gigabit high-performance servers. The BlackDiamond® 8800 and 8900 series switches’ purpose-built core, aggregation, edge and data centre modules meet high-density switching requirements.

• Connect 10GbE application servers with SFP+ or 10GBASE-T to accommodate existing and future cabling architectures.
• Protect investment through cross-portfolio stacking for architectural flexibility and operating system consistency.
• Help control operating expenses with ExtremeXOS operating system’s feature continuity, simplified network administration, and reduced training requirements.
Extreme Networks supports a complete list of standard based protocols including:
• Spanning Tree, VLAN Spanning Tree, Rapid Spanning Tree (IEEE 802.1w), and Multiple Spanning Trees (IEEE 802.1s) protocols for Layer 2 resiliency.
• RIP, OSPF, and BGP layer-3 protocols with graceful-restart extensions to avoid route flapping and improve network uptime.
• Cross module link aggregation (IEEE 802.3ad) that enables grouping of multiple links on a single logical connection (called a trunk). When one link in a trunk fails, traffic is routed to the remaining links in the trunk.
• Unmatched ring-resiliency for Data Centre aggregation and core connections using Ethernet Automatic Protection Switching (RFC 2619) or EAPS in short. EAPS is superior to the Spanning Tree or Rapid Spanning Tree Protocols, offering sub-second (less than 50 milliseconds) recovery and delivers consistent failover regardless of number of VLANs, number of network nodes or network topology. Best off all, similar to other software features from Extreme Networks, EAPS is available across the entire portfolio of fixed Summit and modular BlackDiamond switches.

Extreme Networks provides high performance networks that support data, voice and video for enterprises, carriers and data centres. The company’s solutions differentiate themselves with resilient hardware, modular software and by providing full featured support of network switch and server virtualisation, end-to-end scalability beyond 10 Gigabit Ethernet, ultra low latency, high availability through redundancy and superior resiliency. Extreme Networks helps customers solve their real-world business challenges, from the data centre, to the cloud to the LAN edge, and the carrier IP edge.
Extreme Networks chassis and stackable switches are designed with several hardware redundancy capabilities. The BlackDiamond chassis products for Data Centre End-of-Row and Core leverage a passive backplane and mid-plane designs and provide redundant and hot-swappable fabric, management and control modules. High availability design elements further include isolated control and data planes, hardware-based traffic monitoring, redundant controller boards for power distribution, and fan control and environmental monitoring to identify anomalies before they affect network availability. The power-supplies and fan tray also provide N+1 redundancy and are hot swappable such that the switch continues to operate even under rare cases where individual elements have to be replaced.
The Summit fixed-configuration products for Data Centre Top-of-rack incorporate patented SummitStack™ resiliency that provides quick failover at stacking speeds up to 512Gbps, which is quadruple or higher compared to other solutions in the market. Summit switches for 100M, 1G and 10G connectivity can be combined into a single stack with a single IP address enabling Data Centres to more seamlessly migrate servers to higher speeds without compromising network resiliency by introducing additional switch layers and architectures.
The complete switching portfolio from Extreme Networks leverages a common operating system, ExtremeXOS®, enabling customers to architect resilient Data Centre designs without introducing complexity and variability of multiple operating systems. Further, unlike unwieldy monolithic operating systems, ExtremeXOS uses a modular system design enabling capabilities such as process restart so applications continue to perform under isolated fault conditions. Newer version of services such as SSH can be dynamically loaded/unloaded software without requiring a switch reboot, thus avoiding unnecessary impact to mission-critical customer applications during such changes. Protocols such as OSPF and VRRP run as separate operating-system processes that are protected from each other as shown in the figure below. Additional enhancements to increase Network availability include the ability to monitoring in real time the independent OS processes and automatically restart them in the rare case these processes become unresponsive, or stop running. Introduced in 2003 and on its 12th major production release in 2009, the ExtremeXOS provides common resilient software for Data Centre Top-of-Rack, End-of-Row and Core enabling error-free network-wide policies. With Scripting and XML further an integral to ExtremeXOS, administrators are then able to build robust Data Centre orchestration capabilities leveraging a common Application Programming Interfaces (APIs) for the entire Data Centre infrastructure.
Extreme networks offers a comprehensive and high performance Ethernet network portfolio for wired and wireless LAN from the enterprise edge, to core, to data centre, cloud and service provider edge.
