Design and implementation of an SDH high-speed switch

In this short paper, we propose a design of SDH high-speed switch, which can switch 16/spl times/16 STM-16 streams with speed at 2.488 Gbit/s. In this design a novel fabric structure was used to perform nonblocking connection of STM-1 data in any timeslot of 16-bit parallel STM-16 data rate at 155.5MB/s. The prototype of the design is implemented in Altera's Stratix/spl trade/ GX FPGA devices. The test results show that the prototype meets all requirements.
