Özet:

The increasing use of the internet demands more powerful routers with higher speed, less power consumption and less physical space occupation. IP lookup operation is one of the major concerns in today’s routers for providing such attributes. To accomplish IP lookup on routers, hardware or software based solutions can be used. In this thesis, an SRAM based pipelined architecture proposed earlier for ASIC implementation is re-designed and implemented on an FPGA in the form of a BRAM based pipelined 8x8 torus architecture using Xilinx ISE and simulated and verified using Modelsim Simulator. Some necessary modifications and improvements for FPGA implementation are carried out. The results of our experiments, which are performed for a real router lookup table and a real time traffic load with various optimizations, are also presented. Our study and design effort demonstrates the feasibility of the FPGA implementation of the proposed technique, of course with a considerable performance penalty.
