Broadcom’s New StrataXGS Chip Addresses Network Capacity Issues
The BCM56450 is aimed at networks in need of more bandwidth and management capabilities due to the growth of mobile Internet traffic.Broadcom officials are introducing its latest StrataXGS chip that will enable wireless carriers to better address the capacity and management challenges caused by the rapid growth in mobile and video Internet traffic, the number of connected mobile devices and changes in the mobile backhaul network. The company's StrataXGS BCM56450 switch, armed with an integrated traffic manager and other new capabilities, also will bring a 40 percent I/O bandwidth increase over current Broadcom offerings. In addition, Broadcom's offering will give carriers real-time monitoring capabilities and the ability to create more dense cellular networks with more than twice the amount of user capacity. Broadcom's target for the new chip isn't necessarily the wireless networks, but the wired mobile backhaul networks that run behind them, according to Nick Kucharewski, senior director of Broadcom's Infrastructure and Networking Group. The demands on the mobile backhaul are increasing, due in large part to the growing use of mobile devices like smartphones and tablets and in the growth of data usage per device. Using numbers from ABI Research and Cisco Systems, Broadcom officials said sales of smartphones will rise 24 percent while tablet sales will jump 43 percent between 2010 and 2014. Smartphones use 24 times more data than traditional cell phones, while tablets use five times as much data as smartphones.
All that equals skyrocketing traffic growth over wireless networks, Kucharewski told eWEEK. Citing Cisco figures, he noted that by 2015, 1 million minutes of video content will cross the network every second, and that worldwide mobile data traffic will jump 26 times between 2010 and 2015. In addition, by 2015, the number of devices connected to IP networks will be twice the global population.
