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.

Get the White Paper

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.

At the Open Networking User Group (ONUG) this past October 29th and 30th, hosted by JPMorgan Chase in New York City and attended by over 500 influential IT and industry business leaders, virtualized networking overlays and the need for high performance plus reliable underlays was top of mind. With 2014 and 2015 being the years of open networking pilots and deployments, respectively, much focus was on high-density 40GbE spine switches from Cisco’s Nexus® 9000 series, Arista’s 7500E and HP’s 11900/12900. At ONUG, IT leaders expressed multiple drivers for high-density 40GbE spine switches, including connecting thousands to hundreds of thousands of servers at 10GbE, support for IP storage and the high-growth of virtual connectivity via network overlays, all over a high-performance and highly reliable underlay. In this Lippis Report Research Note we explore the three reference designs for building 288-40GbE spine switches based upon Broadcom Dune, Broadcom Trident II and the new hybrid, custom plus merchant silicon, with an eye toward reliability and available based upon component count and measured in terms of Mean Time Between Failure.

Get the White Paper

By Dr. James Little and Dr. Brendan O’Brien

The rapid increase of mobile devices is making Wi-Fi the preferred method of network access, predominantly within buildings, but also outside. This trend presents businesses with both tremendous potential and unique challenges. Location analytics, in conjunction with the Cisco® Mobility Services Engine (MSE), enables businesses to realize unprecedented benefits from location-based services:

● Location analytics: Estimates the number of visitors, the amount of time they spend, and the frequency of their visits within the site

● Advanced analytics: Provides knowledge of movement patterns by these visitors while they are in the building

Together, these analytics provide detailed insights into general behavior patterns of people moving and interacting within a venue or open space. Location analytics uses advanced data mining techniques tuned to the type of data Wi-Fi location provides. This data is based on potentially millions of position triangulations made per day by Cisco’s MSE. This white paper discusses the technology and capabilities behind Cisco’s location analytics.

The Era of Application Centric Networking

By Nick Lippis

IDC reports that in 2012, Android and iOS combined for 87.6% of the 722.4 million smartphones shipped worldwide, up from 68.1% from 2011. IDC also predicts the expected value of the cloud computing market will increase as much as 130% to $43 billion in 2016. It’s clear that not only are applications being accessed on smartphones and hosted in public and private clouds, but business units are demanding and receiving self-service IT delivery. At the Open Networking User Group (ONUG) in Boston hosted by the Lippis Report and Fidelity Investments large financial service firms showed that self-service Virtual Machine (VM) creation and deletion trend lines are growing exponentially. These trends are powerful, and they are only in the early stages. This poses a challenge to network designers and planners as the rulebook they have referenced for the better part of a decade has become antiquated and a new model to build branch office networks is desperately needed. Download this white paper to find out how to build modern branch office networks in the era of application centric networking.

by Nick Lippis

Cloud and mobile computing deployment has accelerated at a fantastic pace over the last five years, changing the economics of where computing and storage are located, how applications are written and accessed, and most importantly, how corporate computing automates business processes. The pace of change in cloud and mobile computing has been much faster than the evolution of wide area networking, which is now on the critical path to reaping the rewards of modern computing and its favorable business outcomes. Wide area networking, or in particular, the approach to branch office WAN design, is in need of an overhaul as its current form does not support cloud computing. This white paper provides design guidelines for the new WAN in the era of mobile and cloud computing via “cloud connectors.”
