NEC Corporation has 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 Maximisation Solution (Quality of Experience) and a Traffic Visualisation Solution.
The QoE Maximisation Solution 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 Visualisation Solution enables mobile carriers to efficiently conduct traffic control measures by visualising QoE and to design/optimize network and traffic by leveraging such visualised information.
In addition, NEC’s TMS also provides a TMS to SDN Solution that makes it possible to optimise the operation of a network by linking the visualised information with SDN. These features contribute to further revenue growth and business creation for mobile carriers.
“NEC was one of the first companies to offer TMS solutions commercially in EMEA and APAC, where NEC has a strong track record spanning several years of stable, large-scale commercial network operation with total bandwidth of several Tbps (terabit per second),” said Masaaki Nakano, general manager, Telecom Carrier Business Unit, NEC Corporation.
“This solution is built upon NEC’s advanced research and development efforts in packet communication infrastructure and traffic optimization and NEC plans to further expand its TMS solution coverage within EMEA, APAC and North-American markets.”
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 said it has successfully realized its TMS that maximises QoE and minimises 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.
Key Features of the TMS
Superior quality of experience
NEC’s proprietary data flow control technology and tuning expertise enable content download time to be reduced by half, while communication speeds can be doubled.
Moreover, thanks to “Predictive Pacing Engine” technology, this solution can reduce the number of video stalls during video playback during a congested period by over 90% in comparison to existing technologies.
In this way, this solution can maximize throughput while providing users with rich service quality under the condition of limited network resources.
Maximise return on investment
The solution reduces traffic by 30% by combining technologies such as video compression, caching, image compression and text compression. Moreover, the number of concurrent user connections in a congested area can be increased by over 200% without adding radio base stations, helping maximize ROI.
Real-time visualisation of traffic information
The TMS also helps carriers to grasp information and quickly visualize the statistical information of traffic in real time, which takes as much as a full day with conventional batch processing.
In addition, it enhances the effect of optimisation by leveraging traffic visualisation capabilities, such as dynamic tuning features where optimum parameters can be determined and set by traffic visualisation and analysis.
Improvement of optimum network design/operation and customer satisfaction using the TMS to SDN solution
The solution links visualised traffic information with SDN to realize efficient network operation by dynamically designing and reconfiguring networks in accordance with traffic patterns.
Simultaneously, based on the visualised SLA information of particular services, carriers can expand network scale by linking TMS with SDN and can further improve SLA to satisfy users and particular service providers, thereby enabling carriers to offer higher value-added services or solutions to the market.
NEC is showcasing this solution at Mobile World Congress 2014, Hall 3, Stand No. 3N10, from 24-27 February in Barcelona, Spain.
