- 25GbE is the best choice for data centers to address the exponential growth in bandwidth needs driven by mobile data and video. - Upgrading directly to 40GbE and 100GbE is too costly, while 10GbE is no longer sufficient. 25GbE provides a cost-effective migration path as it leverages existing 10GbE infrastructure and delivers 2.5x the performance through a single lane. - A 25GbE ecosystem is developing, including standards work, available FPGA implementations from vendors like Xilinx, and the formation of a 25GbE consortium to accelerate product rollouts within the next 12-18 months.
