By Talari Networks

Software-Defined Networks (SDNs) have the potential to revolutionize data centers and campus networks. However, not enough research has been conducted on the applicability of SDN technology to enterprise WANs. This paper will discuss the SDN architecture, enterprise WAN requirements and how Talari’s patented Adaptive Private Networking (APN) technology begins to apply the value of SDN to the enterprise WAN.

Designing WANs for Today that Position You for Tomorrow

By Ashton, Metzler & Associates

Because cloud services are typically accessed over a WAN, the adoption of cloud computing will place a significant volume of new traffic on the WAN. Unfortunately, in many cases, the cost, availability and performance of the WAN will be an impediment to the ongoing adoption of cloud computing. The use of broadband Internet access technologies, such as DSL and cable, is usually regarded as being low cost, but in many situations, it is not regarded as providing acceptable performance or high availability, such as MPLS. A new approach to WAN design combines traditional and broadband access through WAN virtualization to effectively support cloud computing.

Real Estate Firm Boosts Bandwidth, Cuts Cost with Talari

By Tim Green, Network World

Chicago-based real-estate management company Equity Office ran all its voice and data traffic over a 40-branch office network via a MPLS WAN, costing some $400K per year. But when poor peak-time performance drew complaints from end users, it switched to technology that delivers more bandwidth at half the cost, delivering a 10-month ROI. The new WAN blended DSL, cable, fiber and Ethernet over copper in a single local network via WAN virtualization from Talari Networks,

Virtualization Comes to the WAN with Cost and Performance Improvements

Listen to the Podcast

WAN bandwidth, or the lack thereof, is the single largest contributor to poor application performance in branch offices resulting in reduced productivity and the inability of IT to implement their entire strategy. This is especially acute as applications are increasingly centralized in data centers and video traffic starts to dominate flows all of which put more pressure on the WAN. A new approach to wide area networking takes advantage of virtualization concepts. WAN virtualization promises to reduce WAN cost and increase performance. If your WAN utilizes T1 MPLS links at $300/month or higher and ADSL between $10-$15/ month, then you can benefit significantly from WAN virtualization as it offers 3 to 4 times the bandwidth at lower cost and in the process eliminates WAN design constraints limiting IT business leaders. Keith Morris of Talari Networks joins me to discuss WAN Virtualization. I have first-hand knowledge of how good this solution works; if you fit the above profile, then listen up.

Storage networks present major challenges for data center switches that must be resolved to ensure fast and error-free transport of storage traffic. Force10 S60 switches are purpose-built to handle storage traffic with line-rate performance in Gigabit Ethernet and 10-Gigabit Ethernet networks.

WAN Virtualization – Transforming the Enterprise WAN

Get the White Paper

By Talari Networks

Cloud Computing is making service centralization easier and much more cost effective in the Enterprise. This results in growing demand for scalable, reliable and inexpensive WAN access to deliver new WAN-based services. However the cost of private WAN services like MPLS remain stubbornly high and continued telecom service provider investment in Internet-based wired and wireless (4G) consumer-targeted WANs is delivering as much as a 100x price performance benefit for Internet-based connectivity. In addition, co-location facilities are becoming the lowest cost place to locate server/services and provide diverse low cost bandwidth. WAN virtualization allows IT business leaders to use these higher bandwidth but lower cost WAN services in their enterprise reliably.
