Tripling Capacity, Reducing Cost per Bit for Video Processing Case Study
Considering the market shift to near-insatiable demand for data-consuming Over-the-Top (OTT) services like mobile video, reducing cost per bit is top-of-mind for today’s network operators. 40G ATCA allows operators the capacity and efficiency to both meet this demand and prepare for future technological growth in a cost effective way. Figure 4 below offers a comparison of three common systems currently available for video processing systems, by outlining their processing throughput, video sessions, packet processor, ATCA blades and total platform cost. The table compares two different configurations of 40G and one configuration of a 10G system to allow for relative cost comparisons per bit. While the 40G System B requires the greatest upfront investment, upon closer examination, it allows for the most per-bit cost savings by a wide margin.
At a cost of $130,000, the 40G system configured to process 180 Gbit/s and 324,000 video sessions handles three times the capacity of the 10G system. Although it costs 30 percent more than the 10G system, it delivers a 57 percent savings in cost per bit, when using the most robust 40G setup (System B). This option costs only $0.72 per Mbit/s and $0.40 per video session. When comparing 40G System B to 10G and the 40G System A, the advantages of the 40G System B from a throughput and price efficiency standpoint are clearly delineated.
T40 40G ATCA Allows TEMs, Operators to Outpace Demand
The T40 40G ATCA platform by Radisys, for example, is designed to decrease cost per bit by more than 50 percent and provide mobile network operators with the increased network performance to accommodate the high access speeds inherent in the launch of LTE. Built to Network Equipment Building System (NEBS) specifications and pre-integrated with the leading processors and most comprehensive selection of ATCA blades on the market, the T40 platform has the capacity to deliver high-density Input/Output (I/O). The T40’s customizable COTS format allows operators to utilize it in a wide spectrum of telecommunications applications, including DPI, security and Evolved Packet Core (EPC).
Current and Projected Mobile Data Explosion Calls for Increased Efficiency, Capacity
The past decade’s upsurge of mobile video consumption is forecast to continually increase in pace, making system optimization an undeniable necessity for all players in the mobile infrastructure industry. Cisco’s VNI predicts that the total mobile data growth rate will nearly double every year between now and 2016—an overall Compounded Annual Growth Rate (CAGR) of 78 percent. The case for making the switch to 40G ATCA is clear, when considering the availability of a preintegrated, application-ready platform such as the T40, combined with its measurable cost savings. TEMs can markedly reduce their time to market, increase their R&D output and minimize their investment risk. Mobile network operators can leverage 40G ATCA’s standardized components to upgrade only the systems necessary to achieve 40G and reach a cost-per-bit savings of 57 percent. The migration to 40G provides a truly scalable, customizable solution that is not only beneficial for today’s mobile data requirements, but is configured to handle the projected expansion of years to come.
