Important Considerations When Choosing a WAN Optimization Solution

WAN optimization technology is becoming more strategic to application delivery as IT organizations become more dependent on the WAN for delivery of applications and services to remote users. In initial trials many IT organizations deployed this technology to a few key locations to solve bandwidth or latency challenges. The main selection criteria were around the core features such as data compression and application response time improvements. T…

Many companies are rapidly evolving toward cloud computing, though from different starting points and not without debate as to the best direction or computing model. For example, advocates of public cloud computing sometimes advise not owning any software or hardware or employing any IT administrators and instead relying on professional providers of IT applications, platforms, infrastructure, and services.

802.11n Ratification – What Does this Mean for You?

This final version of the specification is not significantly different from the 2.0 version of the Draft specification to which we have been building products. As a result, our Linksys by Cisco routers will automatically be certified without any firmware or hardware changes. Also, this announcem…
