March 18th, 2014

By Cisco Systems

It’s a mobile world, with almost 7 billion mobile subscribers worldwide in 2013, the equivalent of almost one device for every person on the planet. The rapid increase in mobile devices is making Wi-Fi a preferred method of network access, with the United States having more than 1 mobile device per person and 125 million smartphones shipped every year. With this growth rate, and a predicted 10 billion mobile devices by 2016, organizations can look to mobility and the Wi-Fi network to deliver innovative user services and enhanced customer experience. At the same time, this trend presents businesses with both tremendous opportunities and unique challenges, and numerous innovative businesses are rapidly emerging to help unlock business value from this growth.

Network Technology Performance Evaluation Cisco Wireless High Availability By Syracuse University’s Center for Convergence of Emerging Networking Technologies (CCENT)

February 24th, 2014

Dramatic improvements in wireless networking combined with an increasingly important role for mobile devices are driving a trend towards Wi-Fi as the primary network access mechanism in many networks. An increasing number of enterprise networks, and especially mission critical networks like healthcare, cannot afford to have application sessions drop. These trends are driving CIO’s and network managers to demand increasing levels of service resiliency. Wireless network vendors are addressing these needs by implementing new capabilities, more intelligent wireless networks that are able to prioritize mission critical traffic and dynamically recover from component failures. Cisco approached Syracuse University’s Center for Convergence of Emerging Networking Technologies (CCENT) to perform a systematic beta test, including before/after benchmarking of several applications, of its newest Wireless LAN Controller (WLC) Software (code version 7.5), which includes a new controller failover feature called Client Stateful Switchover (Client SSO). We tested this new service offering on our wireless testbed that included Cisco 5508 Wireless LAN controllers and the Cisco AIR-2602i access point.

Empowering IT Innovations and Reducing Complexity with Unified Access

February 12th, 2014

By IDC

Unfortunately, wired networking equipment and wireless networking equipment have traditionally operated in separate realms, with inconsistent features, policies, tools, and management. This increases the network administrator’s burden and drives up management costs and complexity. Cisco has recently released a new set of unified networking and management platforms designed to bring consistency and continuity to all aspects of the campus network, from the wiring closet to WLAN controllers — and everything in between. By implementing such an architectural approach to unifying wired and wireless networks, IT and network managers can introduce new levels of efficiency, gain greater levels of manageability, and improve user experience. Enabling greater levels of business innovation and growth while controlling costs, IT can demonstrate how it is driving innovative value-add to the business.

August 11th, 2013

By Lippis/Ixia

The Cisco Systems Nexus® 3548 is the fastest ToR switch that we have tested at these Lippis/Ixia tests by a large amount. The Nexus® 3548 forwards packets in slightly more than half the time of the next fastest switch we have tested! That is, it’s nearly twice as fast as the fastest previous switch tested. The Nexus® 3548 is also the fastest IP multicast forwarding switch we have tested to date, being able to forward packets some 62.5% faster than the previously fastest ToR switch tested. The Nexus® 3548 is an engineering achievement for both its raw packet processing performance, congestion management and value added Algo Boost and Warp Mode technology.

Lippis Report 207: The Killer SDN Applications: Network Virtualization and Visualization

April 8th, 2013

nicklippis.jpgAt the last Open Networking User Group (ONUG) meeting in Boston organized with partner Fidelity Investments, it became very clear that there are two killer SDN applications: network virtualization and visualization. Some argue that network virtualization used for VM-VM networking is not an SDN technology, but I beg to differ. Sure, there are closed and open approaches to network virtualization, but over the next business cycle, the integration of OpenStack and OpenFlow will make it clear that network virtualization is an SDN application, especially as it’s extended to physical networks. The second killer app is network visualization—that is, the ability to monitor network traffic and tweak application performance.   At ONUG Rich Groves, Principal Architect at Microsoft presented his SDN based approach to network visualization he designed with Big Switch Networks, cPacket, IBM, Arista and other suppliers that everyone is now using.  Why is network visualization an SDN killer app? Because it uses SDN technology, and most importantly, lowers the capital cost significantly from existing network visualization approaches while also delivering an entirely new level of self-server flexibility. Companies, such as Big Switch Networks, Gigamon, Arista, Cisco, NetScout, Ixia/Anue, cPacket and others, are now positioning their network visualization offers within an SDN context and for good reason. In this Lippis Report Research Note, I focus on network visualization as an SDN killer app.

Lippis Report 201: What Comes After Zero Latency Switching?

November 5th, 2012

During mid-September 2012, Arista Networks and Cisco Systems launched what both claimed to be the industry’s lowest latency switches aimed at big data, cloud, Web 2.0 and high frequency trading markets. Both products are Top of Rack (ToR), 10 and 40GbE switches. Arista’s is based upon merchant silicon, while Cisco utilized custom ASIC. Arista’s 7150 Series claims 10 and 40GbE, 350 nanoseconds Layer 2 or 3 forwarding, VXLAN support and what it calls “flexible forwarding.” Cisco’s Nexus 3548 claims 10GbE, 250ns to 190ns Layer 2 or 3 forwarding, and Cisco Algorithm Boost or Algo Boost technology. At 10GbE speeds, a bit is 1/10 of a nanosecond long, so Arista’s 7150 and Cisco’s 3548 switches delay is 3500 and 2500 or 1900 bits, respectively. That is, these products offer processing delays equal to the time it takes a few thousands of bits to traverse a simple metallic or optical wire at 10Gbs! In this Lippis Report, we review Arista’s and Cisco’s new ToR switches and answer the question: what comes after zero latency switching?
