Today, Telstra announced a hybrid network architecture resiliency trial of Nokia's IP Multimedia Subsystem (IMS) software in a world first collaboration with Amazon Web Services (AWS) and Nokia.
The deployment and completion of an internetworking IMS resiliency trial on the AWS cloud promises new ways to build network resilience and reliability in Telstra's fixed and mobile network. The trial will provide continuity of voice services during certain unplanned network interruptions, where the primary solution is not working correctly. The trial orchestrates and delivers another IMS from another supplier leveraging cloud technology to keep voice services working.
The IMS trial stems from a long-standing strategic relationship with AWS to drive Telstra's network leadership, particularly through activities aimed at increasing network reliability, resiliency, and customer experience.
"Telstra has a long history of global and domestic network leadership and innovation. The deployment and completion of our IMS trial with Nokia on AWS is a strong demonstration of what is possible from our strategic collaboration," said Shailin Sehgal, Telstra Network Applications and Cloud Executive.
"For us, success is delivering an incredible experience for our customers. This means leading the way with new technology and services, which can only be done by collaborating closely with AWS to leverage their world class cloud infrastructure, which offers a secure, consistent and reliable environment for our applications."
Building an intelligent and more resilient network for the future
As part of the ground-breaking IMS trial, the Nokia IMS is deployed on AWS via a hot standby set up, where dynamic scaling of the IMS in the cloud for both infrastructure and application capacity is available.
The trial shows the potential for on-demand capacity in an unplanned network disruption scenario. When deployed at scale this will provide enhanced network resiliency by allowing call control to be supported by the cloud, rather than experiencing a network disruption. Telstra is now working with AWS and Nokia on expanding the trial beyond Voice over LTE on IMS to include full scale of network provided services.
"This dynamic network management means that if one part of the network goes down, the network can autonomously adjust its configuration to ensure the smallest possible number of customers and services are affected. The trial has been a huge success and the learnings and achievements we've gained will be invaluable as we continue developments in this area," said Mr Sehgal.
"It's another way we're building a more resilient network and working to keep our customers connected if unplanned network events occur."
"We've been on a journey to help Telstra and its customers adopt cloud-native technologies to increase their pace of innovation and productivity. Today's IMS announcement with Nokia means Telstra can further improve their network's resiliency and availability through the on-demand scale and flexibility of AWS. We're pleased to see the successful trial will help Telstra protect and enhance their customer experience and service delivery if an unplanned disruption occurs," said Chivas Nambiar, General Manager, Telco Business Unit, Amazon Web Services.
Vishal Singh - Senior Vice President - Global Business, Cloud and Network Services Business Unit, Nokia said, "Nokia is pleased to collaborate with Telstra on their industry leading resiliency program with our IMS Cloud Native Communication Suite. Together we were able to demonstrate end user experience can be maintained during an unplanned network disruption by providing a totally independent, scalable, secure and robust solution. "We are looking forward to ongoing collaboration as we work together to bring these capabilities to market."
