摘要
The fast increasing of FIB has put unprecedented pressure to the Internet routers. The decomposed storage of FIB has theretofore been widely suggested, which explores the balance of storage overhead over routers' line cards. SPAL can achieve the decomposed storage of FIB, but its implement is very complex, and there exists many redundancy storage of FIB. In this paper, we propose a novel decomposed storage model of FIB, DSF (Decomposed Storage of FIB), which can reduce the unnecessary redundancy of FIB storage across line cards. Moreover, we discuss an enhanced mechanism: EDSF. The real-FIB experiments show that EDSF can further minimize the diversity of line cards' storage. The design and the implementation of our proto type is also validated in detail showing that the proposed architecture is compatible with the existing commercial core-routers.
