Looking to boost real-time communications in the cloud, Sonus Networks unveiled new capabilities for members of its cloud family of products, a move the vendor expects to simplify and accelerate CSP implementation of virtualized solutions.
These enhancements come at a time when CSPs' adoption of cloud and virtualization are becoming more complex and entering more critical business areas, says Kevin Riley, Sonus CTO, in an interview.
"They've been working their way from the outside in, to the core. They've been virtualizing from the customer premise, mostly from the CPE. Then it moved to the access edge, now it's shifting in earnest to the core," he says. "We've been partnered with some leading customers -- not just for Sonus but in the industry -- to shape our offer and move forward and now we're at a good point to show we're moving forward. Is everybody virtualizing their core yet? Absolutely not. That part of the transition is early... That turn-up will start to happen in 2017."
Sonus Networks Inc. (Nasdaq: SONS) developed cloud-optimized versions of its Element Management System (EMS) and PSX Centralized Policy and Routing Engine, plus a microservices version of its SBC SWe cloud solution, the company says. This optimization allows CSPs to instantiate virtual policy, routing control and virtual session management, Sonus says. The vendor also delivers solutions for geographic redundancy, high availability and load balancing across numerous virtual network functions (VNFs).
Sonus uses microservices to separate signaling, media processing and transcoding into separate components, allowing independent orchestration and scaling depending on network traffic.
"They are like Lego blocks that can be reassembled arbitrarily," says Riley. "That was customer-directed because that allows them to scale our capabilities throughout their network."
An embedded data agent in every VNF instance communicates traffic and usage information into a cloud-based data warehouse for analytics, he says. This information is used for on-demand VNF management, optimizing resource usage at the microservices level, monitoring and troubleshooting, adds Riley.
"We have the proper tools now that allow the CSP to visualize where our applications are running, how they're running, are they meeting the SLA, and provide the visibility into the application as they're running," he says. "That's become increasingly important as we switch to software because you can't see and feel the app as it's running."
