YOUTH DRIVE VIETNAMESE MOBILE DATA MARKET


Add Vietnam to the long list of countries where teenagers and young adults use more mobile data than any other demographic. Half of all Vietnamese ages 15-24 use mobile data, says a recent Nielsen Company study. That group regu- larly accesses the mobile Internet at triple the rate of all Vietnamese mobile users. Vietnam Mobile Telecom


Services Company (VMS), which sells service under the MobiFone brand, is revamping its transport network to meet that demand. At a Tellabs workshop, VMS learned that many Tier 1 mobile operators use MPLS to support 2G and 3G back- haul. VMS subsequently deployed the Tellabs®


8600 Managed Edge


System as part of its 3G upgrade. “Instead of using TDM and


separate Ethernet circuits, we can aggregate all that traffic onto one transmission link,” Nguyen Dang Nguyen, VMS vice president of network planning and management, told Insight in late 2010. Nguyen estimates that using the Tellabs 8600 system has reduced its back- haul lease costs by at least 30%. 

Service providers face a tough balancing act. Network traffic is growing exponentially, driven by high-speed Internet, high-definition video and business services. One answer is to add more bandwidth. But service providers also are under pressure to reduce costs to maintain profitability. A better option is to use the current network capacity to enhance service offerings. Standardized Optical Transport Network (OTN) switching meets these network needs. Available now on the Tellabs®


100 Gbps per optical wavelength scalability and switching rates over 1Tbps support future bandwidth growth.


7100 Optical Transport System, OTN switching


Tellabs’ OTN offering improves traffic delivery by reducing the service provider’s overall cost per bit of transport by as much as 80%.


enables service providers to aggregate and encapsulate a variety of traffic, including native Ethernet and SONET/SDH. The Tellabs 7100 system also enables them to transport it as an aggregated traffic bundle across backbone networks. The low-latency solution also enhances


business and enterprise services. Because the OTN switching is service transparent, multiple customers’ traffic can ride on the same wavelength and reach their destinations quickly, securely and reliably. “With dynamic optical networking,


packet switching and OTN technology on one platform, service providers can rely on unparalleled flexibility and resiliency in their optical networks,” said Dan Kelly, executive vice president, Tellabs global products. “With OTN on the Tellabs 7100 system, service providers can scale as their networks grow and cost-efficiently aggregate all services to create a truly converged transport network.”


Investment protection for the future The Tellabs OTN solution also positions service providers well for the future. For example, OTN capabilities can be rolled out as needed. The solution also has capacity to support continuous bandwidth growth with the capability to scale to 100 Gbps per optical wavelength and switching rates of more than 1 Tbps.


Flexible deployment for all OTN switching makes sense for all types of service providers that face growing network traffic: mobile, wireline, cable operators and government agencies. The Tellabs 7100 system’s flexibility and scalability of the Tellabs OTN solution can reduce costs and improve transport network efficiency, no matter what type of services are offered. 
