Radware Demos 20Gbps Performance, Emphasizes Need for ADCs

By Paula Bernier April 29, 2016

Radware in a demonstration with 6WIND’s Virtual Accelerator showed that the 20Gbps performance of its Alteon NG Virtual Appliance with OpenStack in an NFV environment is five times that of the nearest competitors. That kind of performance is important, the company explained, because while OpenStack is good for network optimization, virtual application speeds slow dramatically.

“As we've now proven, it's wholly conceivable to run an NFV architecture in an OpenStack environment that's capable of managing a high load without a degradation in service," said Frank Yue, director of solution marketing, application delivery for Radware and a standing INTERNET TELEPHONY magazine columnist.  

As Yue writes in his Application Networking column in the upcoming June issue of INTERNET TELEPHONY, IT infrastructures are increasingly becoming virtualized to allow for more dynamic and flexible application delivery. However, he notes, orchestration and automation systems for virtualized architectures can greatly alter the infrastructure’s application delivery characteristics by enabling elasticity, which is a good thing, but also more opportunities for misconfiguration or other problems, a not so good thing.

“The evolution of IT architectures to these virtualized designs cannot succeed if we replace stability with agility, since the flexibility of the application delivery infrastructure doesn’t matter without stability,” he adds. “Having the fastest car is irrelevant if it only runs 10 percent – or even 90 percent – of the time. We need technologies and functions that can ensure the stability of these dynamic software-based architectures.”

The good news is that application delivery technology can ensure the stability of application delivery from client to server so when an application server fails, its load balancing function can automatically detect and mitigate the failure.

“If the problem is location- or network-centric, global server load balancing technologies can redirect the application traffic to available resources,” he explains.
