OREANDA-NEWS. NEC Corporation announced the start of sales for its enhanced "Traffic Management Solution" (TMS) for improving the display speed of web content, decreasing video stalls during video playback and creating greater Return on Investment (ROI) on carrier networks.

This solution enhancement, on top of NEC's existing Traffic Reduction Solution, adds a new "QoE Maximization Solution" (Quality of Experience) and a "Traffic Visualization Solution."

The QoE Maximization Solution drastically improves QoE by dynamically tuning system parameters for each unique user-flow. This solution is realized by various tuning technologies built on NEC's best-of-breed technical capabilities and rich experience.

The Traffic Visualization Solution enables mobile carriers to efficiently conduct traffic control measures by visualizing QoE and to design/optimize network and traffic by leveraging such visualized information. In addition, NEC's TMS also provides a "TMS to SDN Solution" that makes it possible to optimize the operation of a network by linking the visualized information with SDN. These features contribute to further revenue growth and business creation for mobile carriers.

In recent years, mobile carriers are accelerating the introduction and coverage expansion of LTE networks to cope with surging mobile traffic. Generally, the introduction of LTE is meant to deliver faster throughput. However, it does not always satisfy the expected level of throughput, and QoE degradation takes place because traffic concentration and network bandwidth fluctuation occur when users are moving from one location to another.

One of the general methods to improve QoE is to expand network capacity, but this requires enormous investment.

NEC has successfully realized its TMS that maximizes QoE and minimizes investment by adapting to the changing characteristics and conditions of mobile carriers' networks. This enables mobile carriers to continuously provide an optimum level of high quality services to users.
