In the context of service fulfillment, most operators are saddled with numerous siloed service fulfillment solutions customized for every service vertical. These siloed solutions are created and maintained to support services crossing different network devices and vendors, which leads to significant funds being invested with legacy OSS vendors and is a systemic hit every time a new service is added. Further, these ad hoc developments are not designed to be future-proof, but are tactical efforts undertaken to alleviate a given problem.
System integration, professional services and support costs are a major impediment for most service providers. Heavy Reading research shows that Tier 1 operators spend on average 40-45 percent of their IT budgets on maintaining their legacy OSSs. Time to market of new services remains stubbornly high with an average of six to nine months. Opportunity costs for delayed service launch runs into the millions of dollars, negatively impacting the operator's bottom line.
It is, therefore, not a surprise that as the number of services, the number of vendors to support, the growing appetite for sophisticated security systems and the evolution of network architecture accelerates, this legacy of ad hoc service fulfillment design becomes a roadblock in the way of service providers' transformation vision.
To bring home the point and suggest solutions, Trade Commission, Embassy of France in India and UBIqube Solutions of France jointly organised a seminar on ‘Reinventing Network and Security Orchestration in a World migrating to SDN (Software Defined Network) and NFV (Network Functions Virtualisation)’, on 18 November 2014 at Hotel Taj Palace, New Delhi. The Seminar was well attended by professionals from the broadband and telecom industry. Virtualization promises hardware vendor independence, improved operational efficiency, standardized and open interfaces and the dynamic chaining of network and IT functions to create new "integrated" services. The current industry attention paid to software-defined networking (SDN) and network functions virtualization (NFV) trends stems from the above.
SDN & NFV both promise hardware vendor independence, improved operational efficiency, standardized and open interfaces and the dynamic chaining of network functions to create new services. While potentially bringing disruptive benefits to the networking industry, these technologies also come with their own sets of challenges. Key among these is service orchestration and management in particular when legacy network architectures are to be part of a hybrid service delivery solution.
This model of NFV is also suitable to the video delivery networks like the cable TV networks where cloud based software architecture can manage a set of small cable networks as exists in India to achieve the same efficiency and economy as achieved in a large network of a National MSO. A white paper on ‘Adaptable Orchestration Framework for Seamless Service Fulfilment’, researched and written by Heavy Reading for UBIquest was presented to the delegates, Speakers at the seminar included Mr Nabil Souli, Chairman and CEO of UBIqube Solutions, Mr Flerve Guesdon- VP of engineering and CTO and Mr Rama Murthy – industry consultant.
