New Clouds Old Clouds and Virtualization
The world is abuzz with the possibilities of the Cloud, but today’s “Cloud” is not a new concept. What is new is the ability to virtualize and host applications and content on a massive scale while offering content to the public on demand in the manner of Netflix and other vendors. Private clouds have existed as long as networking has existed, albeit under different names, such as “server farms” and mainframes. A good example is corporate email, which is often stored on a central server (the “cloud”) and not on each employee’s individual computer.
For many enterprises, the ability to virtualize applications and services (such as access point control) rather than the ability to purchase hosted services from a public “Cloud” is what offers real and dramatic change.
Virtualization promises to revolutionize cost savings and enterprise access to critical programs within businesses. In order for that promise to be fulfilled, enterprise networks must be ready for an unprecedented increase in high-bandwidth wireless traffic from smart devices seeking to run these virtual applications. Avaya WLAN solutions have been designed to both enable cloud applications and to leverage cloud services. A split-plane architecture allows the control plane to move into the private cloud as a virtualized service while independently scaling the application plane to handle the explosion of traffic over wireless as users leverage private and/or public cloud-based applications. Splitting the two planes and leveraging the Cloud for both maximizes the effectiveness of each.
Offloading data forwarding to Ethernet switches gives Ethernet-quality performance and line-rate, non-blocking throughput based on current ASIC designs, regardless of packet tunneling. This ensures peak performance for the application traffic, maximizing throughput and reducing latency.
