"Standards-based is fine, but standards-based plus is really what you're looking for with large scale, highly-reliable enterprise network deployments," Rau said.

Rau also addressed a question during the webcast about whether or not he thought taking a multi-vendor approach was the right path to build a next generation network.

"One of the benefits that an end-to-end Cisco infrastructure delivers is a large amount of test and integration work that we do," Rau said.

Rau added that an enterprise could do that with multiple vendors, but it would take time to do all the test and integration work. In his view, the benefit of having Cisco end-to-end is a higher level of service.

QoS isn't enough

Rau also address the myth that having a basic level of Quality of Service (QoS) in a network is good enough. With the rise of video demand on networks, QoS requirements have changed.

"There is one thing that is really true about video, throwing bandwidth at video doesn't necessarily solve the problem of doing large scale management and control," Rau said. Part of the challenge with video is how to do you manage it when there is a request for more bandwidth than is available?"

Rau suggested that new QoS services are required to meet next generation video networking needs and good enough isn't good enough for video.

"In addition to QoS, we also have to bring in capabilities to mange control and troubleshoot video," Rau said.
