| Abstract(in English) | TCAM (Ternary Content Addressable Memory) is widely used for high speed address lookup. However, TCAM has a potential problem on hardware cost and energy consumption, which limits to deploy large amount of capacity in IP routers. In this paper, we propose a new TCAM-based hardware architecture which reduces significantly power consumption. The proposed architecture consists of multiple sub TCAMs and a indexing table. We also propose a method to select appropriate bit posisions used for indexing based on the statistical characteristics of routing table. Our numerical results show that the proposed method can divide the whole routing table neally equal to sub TCAMs. |
