Networking vendors and operators are now mustering to address and benefit from the sea change that SDN/NFV represents, making this an opportune time to establish a broad industry ecosystem, not a series of ‘ego-systems’ revolving around particular vendor implementations, forming competing siloes, and reducing the scope and sweep of operator choices. The successful establishment of an expansive ecosystem requires embracing expansive openness throughout the top-to-bottom architecture.

This white paper assesses the impact of the emerging network virtualization technologies of network function virtualization (NFV) and software-defined networking (SDN) on the operational processes and support systems of communication service providers (CSPs). It outlines the key role the OSS will play in enabling CSPs to deploy and realize anticipated benefits from service agility, operational flexibility and cost optimization.

Virtualization brings the promise of renewed competitiveness to telecom operators, allowing them to move forward with agility, speed and cost savings. As with all new technologies, it requires changes in how operators manage their business processes in procurement, planning and operations. 

Metro Networks Are Growing and Changing Driven by the increased adoption of cloud technology and applications, traffic volume is growing at an average rate of 30 to 50 percent annually in metro networks, even more in some cases. At the same time, service providers are finding that they cannot charge the same amount for transported bits, so they are expected to invest in increased network capacity without an equivalent rise in revenue.

Communications Service Providers (CSPs), need to innovate to keep up with the competitive pressure of the rapidly changing network environment. As more of the value (and revenues) flow to over-the-top service providers like Google and Amazon, CSPs face the prospect of increasingly becoming providers of commodity-like transport services.

Carrier Ethernet is on a massive uptake trajectory. However, its application in transport networks relies increasingly on third party access vendors (AVs) to fill coverage gaps and increase the service provider’s transport footprint. In this paper, CENX explores the service orchestration challenges of off-net circuits. It highlights the need for a new generation service orchestration approach that enables critical inter-carrier use cases such as audit and inventory, ordering, fault isolation, and SLA management required to ensure an optimal customer experience across multiple carrier domains. Finally, it discusses why inter-carrier service orchestration will remain highly relevant in the transition from today’s IP network to the next generation software defined network (SDN).

The coming challenge for Wi-FiTMoffload is to provide a converged network solution for a seamless, transparent and better user experience. The user will not have to interact with its smartphone or mobile device in any way to switch from 3G/LTE to Wi-FiTM. The data stream will even be able to use both connections at the same time depending on QoS requirements.

This short guide explores the technical aspects of Wi-FiTMoffload architecture and its related capabilities. It is presenting the different types of possible integration into existing mobile networks to provide a viable and efficient way to offload subscriber traffic. It concludes with an overview on testing methods.

New report compares the service experience of Over-The-Top (OTT) video chat across leading smartphones. This study was designed to measure the mobile video chat experience for today’s top selling devices, leading LTE networks and most popular OTT applications.

Find out how FaceTime, Skype, Blackberry Messenger and Google Hangouts compare across a number of top devices.

Consumers are demanding the highest Quality of Experience (QoE) from their mobile devices. Bringing new products and services to market is harder than it’s ever been. You need to know how good your QoE is before your customers find out themselves.

This report demonstrates how QoE can be tested before launch to avoid negative customer experiences.

Virtually all service providers have a large installed base of legacy SONET/SDH equipment from multiple vendors. This equipment is not suited to the dynamic telecommunication networks of today. As spare capacity on networks dwindles and older equipment approaches the end of its service life, operators must decide whether to continue investing in outdated, inefficient equipment that does not meet the requirements of today's packet-based, dynamic networks, or transition to a new mode of operation that helps capture additional market share and drive higher revenue while lowering costs.

Today’s enterprises rely on an array of high-bandwidth applications and services every minute of every day, from voice and video conferencing and cloud computing to mobile data services. The corporate networks that support these services have become mission-critical in the most literal sense, as even a minute’s downtime can reduce employee productivity, interrupt revenue-generating services, negatively affect customer service, and cause long-term damage to a company’s reputation. This paper addresses how enterprises can maximize network uptime and performance by partnering with true network specialists instead of managed services generalists.
