Using network virtualization to allocate WAN bandwidth

One key way WAN managers can apply network virtualization technologies is to create multiple virtual network "channels" on the same physical network. Many IT organizations are concerned not only with whether they are allocating enough bandwidth to each of their business-critical applications but with how applications on the same physical networks are affecting one another. Creating virtual channels and assigning each of these channels to individual applications enables organizations to ensure that each critical application can be seamlessly transferred across the network and ensure that new technology rollouts are not causing deterioration of existing business services.

New applications, IT initiatives and end-user requests for improving the effectiveness of managing enterprise infrastructure are changing the role that WAN optimization solutions play in the enterprise. Benefits that end-user organizations are looking to achieve from deploying various WAN optimization and accelerating technologies go beyond just mitigating bandwidth upgrades and improving network throughput. WAN optimization solutions are becoming one of the key enablers of top IT initiatives. IT projects such as data center consolidation and desktop and server virtualization improve the flexibility of managing computing resources; but, at the same time, they are moving computing resources further away from the end user, which increases the amount and complexity of data that is being transferred over the WAN.
