Policy Control for Carrier Service Delivery

Policy-based control technologies have matured to the point where they can now be deployed by network operators to meet on-demand, multiservice network requirements, according to a new report issued by Light Reading's Services Software Insider.

"Policy-Based Service Control: Rules of Order" analyzes and evaluates the approaches to service-related policy control, network resource control, and bandwidth management now being defined in various standards bodies. The report provides a detailed accounting of what policy control does, how it works, and how it fits into the overall context of the service delivery platform (SDP).

"The nature of the telecom service business is changing � services are becoming more numerous, varied, and complex," notes Caroline Chappell, lead analyst and author of the report. "Operators expect to sell hundreds if not thousands of services, which means service delivery may soon require a wide range of policy-based variables, including presence management, time of day, device type, subscriber permission, subscriber preference, subscriber age, location, role, billing arrangement, and many others. Operators will need to store the expanding range of parameters that can be applied to individual subscribers and check against these to see which features apply as soon as a user requests a service."

Key findings of the report include the following:

-Service providers absolutely need policy control to manage new, disparate network services.
-Operators now see the benefit of creating an overarching policy-control framework.
-The main barrier to inter-operator policy control is economic, not technical.
-Tazz Networks has the early lead in policy control, but competitors are gaining ground.

Digital Talent Demand Exceeds Supply in Asia-Pac

Even the savviest CEO's desire for a digital transformation advantage has to face the global market reality -- there simply isn't enough skilled and experienced talent available to meet demand. According to the latest market study by IDC, around 60-80 percent of Asia-Pacific (AP) organizations find it "difficult" or "extremely difficult" to fill many IT roles -- including cybersecurity, software development, and data insight professionals. Major consequences of the skills shortage are increased workload on remaining digital business and IT employees, increased security risks, and loss of "hard-to-replace" critical transformation knowledge. Digital Business Talent Market Development Although big tech companies' layoffs are making headlines, they are not representative of the overall global marketplace. Ongoing difficulty to fill key practitioner vacancies is still among the top issues faced by leaders across industries. "Skills are difficul

Mobile Device Market Still Awaiting Recovery
