NetReality, Sonus in VoIP Partnership

(Telephony) NetReality has joined Sonus Networks’ Open Services Partner Alliance and will add its network application priority switching expertise to the voice-over-IP interoperability effort.

NetReality’s technology shapes and tags packets, including those carrying voice over IP, to prioritize their transport over IP networks.

“It's very important that you prioritize voice-over-IP traffic, because it’s very sensitive to latency, issues of delay,” said Kit Waugh, vie president of marketing and business development. “Equally, it’s important to be able to cap the number of sessions that you can run at any one time, because they will starve any of your other applications from having connectivity.

In this way, NetReality’s technology advances beyond MultiProtocol Label Switching (MPLS) that labels packets to improve quality of service and efficient network transport, he said.

“It’s important that you have some kind of device somewhere on the network that is differentiating the traffic types and doing that MPLS labeling,” said Waugh. “Ours is that device. We actually put on the label for MPLS so that, when it gets to the carrier IP switch, it knows which path to take.”

The Sonus partnership is important as NetReality demonstrates that it interoperates with other VoIP products, Waugh said.

“Sonus has emerged as the pre-eminent voice services switch in the marketplace,” he said. “They’re a market leader, and it’s very important to them to have a device like ours that can actually do this classification and do this tagging to support their product and support the services the carriers are running for their product.”
