7. Branch networking: Comparing branch office routers
Branch office routers can do more than offer simple wide area network connectivity these days. Compare what features vendors are integrating in the branch office routers, such as QoS capabilities and Wi-Fi access.
6. Using QoS to limit bandwidth
In 2011, bandwidth didn't get any cheaper, so finding ways to use it resourcefully was a top-of-mind priority for enterprises. This top WAN tip explained how using QoS to limit WAN bandwidth can give your business-critical applications priority over more recreational traffic.
5. How to set up WAN simulators to test branch application performance
Assuring a good user experience of WAN-based applications is another fundamental part of a network architect’s job -- one that involves measuring WAN latency. While you can use ping to measure network latency, many IT pros use a WAN simulator to test branch application performance. This top tip for 2011 gives step-by-step directions on how to set up any network simulator.
4: Application delivery optimization: Five tips for success
In discovering WAN latency, a vast majority of IT professionals will realize they need application delivery optimization (ADO). But how do you roll out a successful ADO deployment? Read this article to get five tips for success.
3. Video conferencing bandwidth requirements for the WAN
2011 made it evident that video traffic is acceptable to use in an enterprise for communicating, training and informing.
