Web支援OpenFlow的交換器中的路由表多是由三元可定址內容記憶體(TCAM)所製成。然而，TCAM在軟體定義網路網路中是一項很昂貴的資源，所以如何有效率地去使用TCAM容量，是軟體定義網路中很重要的議題。規則快取則是一個能有效率使用TCAM容量的方法。 WebThe “don’t care” state allows the TCAM to flexibly match any one of four search words – "10000," "10010," "10100," or "10110." Adding a “don’t care” state is done by adding a mask bit for each memory cell and increases complexity even more. A priority encoder in the TCAM ensures that only the first matching entry is output.

WebAug 12, 2005 · Here are some more TCAM allocation examples. Just because, for instance, 8K is allocated to routing tables, this doesn’t mean that you can only have a routing table of that size. There’s always the fallback of process switching. Process switching means that everything will be done by the processor instead of in hardware (TCAMs).
