BIGLOBE doubles network throughput with NEC's traffic management solution

NEC has announced that BIGLOBE, a mobile virtual network operator (MVNO) and a major Internet service provider in Japan has selected NEC's Traffic Management Solution (TMS) to deliver higher quality of experience (QoE) for their mobile communication subscribers. NEC's TMS automatically controls the volume of packets transmitted over the network in response to traffic conditions. This makes it possible to optimise the packet flow rate at a level that will not impair the user's QoE during times of traffic congestion.

The TMS, implemented in BIGLOBE's commercial networks, has doubled network throughput, enabling end users to enjoy Web browsing and video streaming with lower latency and greater stability. Specifically, BIGLOBE has improved network throughput by as much as two times on weekdays from early in the evening until late at night when traffic is particularly heavy.

"In order to deliver high-quality mobile communication services for our customers, we looked for innovative solutions which can prevent QoE deterioration," said Masaaki Nakano, SVP, BIGLOBE. "Implementing NEC's TMS has allowed us to minimise packet loss and increase network throughput during times of congestion, enabling our customers to enjoy higher-speed communication services with their smartphones and tablet devices."

"MVNOs face the challenge of utilising network bandwidth borrowed from mobile network operators as effectively as possible to boost profitability while at the same time providing end users with a high QoE," said Atsuo Kawamura, SVP, NEC Corporation. "Managing deterioration of communication quality during times of congestion is a key factor for MVNOs to improve end-user satisfaction. NEC is pleased that the implementation of its TMS has allowed BIGLOBE to dramatically improve throughput, which will be a key differentiator for their mobile services."

NEC's TMS has been implemented by more than 10 telecommunications operators globally.
