Improved three-level CLOS routing algorithm based on FPGA crossover

Abstract

The invention relates to an improved three-level CLOS routing algorithm based on FPGA crossover. Based on the internal crossover capability of the FPGA, the invention realizes a routing nesting algorithm of the two-layer three-level CLOS network for realizing the input and output routing crossover function of an optical fiber signal. The first layer of three-level CLOS network increases a design strategy of intermediate-level merge, and the connection between the input and output stages and the switching stage is increased from one connection channel of the traditional architecture to four connection channels, which increases the routing space. The second layer of CLOS network calculates the on-chip routing of the FPGA, and implements a direct-cut mode in the scenario of board crossover without occupying the switching-level resources to increase the routing space, thereby having the advantage of greatly reducing the blocking rate in the scenario of large-capacity crossover. The improved three-level CLOS routing algorithm based on FPGA crossover increases the routing space through the improvement of the architecture and the algorithm, greatly reduces the blocking rate, and improvesthe equipment performance advantage and user experience.
