Broadband Service Providers Invest in SDP

According to a new study, fixed and mobile network operators will invest a total of $4 billion in service delivery platform (SDP) capital infrastructure over the next five years. One question remains, however. Will providers fully utilize these flexible platforms to co-create new engaging services with third-party developers -- and their customers -- or will they continue to create controlled walled-garden applications?

Applied wisely, the SDP investment will potentially yield a significant payoff, both in reduction of operating expenses for Intelligent Networks and IP networks, and in the creation of new revenue from IP-based services. Worldwide, ABI Research forecasts that operators will generate $49.6 billion in service revenue from IMS-enabled applications in 2011.

"Telecom networks are going through a period of profound change as they adopt service-oriented architecture and implement IT systems based on open standards," says ABI Research analyst Ian Cox. "This brings with it all the advantages of a vast range of new data services, beginning with click-to-dial but rapidly moving to rich voice sessions, all under the control of next generation service delivery platforms."

Cox further comments that "Progress is also being made on integrating network and Web-based services and developing secure and reliable charging solutions for complex user sessions. But additional work is needed to formalize the relationship between IMS, service delivery platforms and session border controllers."

For users, says Cox, SDP will allow many new services, including VoIP, to be offered over SIP-enabled networks. Each service � instant messaging, for example � can be used at the same time as another service because the user will be able to see the "presence" of another user. It also allows users to have a single device that can be used on both fixed and wireless networks.

For vendors, SDP will allow specialist firms to develop applications and equipment independently of each other, secure in the knowledge that they will work together and can be deployed by any service provider. SDP enables new services to be introduced quickly, tried and discarded if they are not popular. A single database holds all subscriber information, leading to lower operating costs for multiple services over multiple access technologies.

The Cloud Imperative for Telecom Operators

The telecom sector is undertaking an update of its IT infrastructure. As demand for data continues to soar with the proliferation of 5G and new apps, network operators can't rely on their legacy hardware and network architectures. The process of "Cloudification" offers a path to reduce costs, improve efficiency and scalability, plus meet increasingly ambitious infrastructure sustainability goals. According to the latest market study by Juniper Research, cloudification spending by telecom operators will see tremendous growth in the coming years, rising from $26.6 billion in 2024 to $64.9 billion by 2028 -- that's a 144 percent increase in just four years. Telecom Cloud Apps Market Development "Telecom networks are becoming more complex; requiring increasingly automated network management systems. However, operators must insulate mission-critical traffic when reducing power, to guarantee quality of service for enterprises," said Alex Webb, research analyst at
