| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | An emerging data structure, a learned index structure, which uses machine learning to associate key-position pairs in a key-value store. We have applied learned index structures to a forwarding information base (FIB) of IP, referred to as a learned FIB. The learned FIB consists of the following two phases: First, it predicts the position of the FIB entry corresponding to an input IP address by leveraging a machine learning regression model. Second, it searches around the predicted position for the FIB entry to correct errors caused by the regression model. In this study, we optimize our implementation for lookup speed, exploiting that for fast FIB lookups it is enough to approximate the key-position pairs with a piece-wise linear function, instead of having to learn the key-position pairs. The experiments using real BGP routing information snapshots suggest that the size of the proposed FIB is compact and lookup speed is sufficiently fast regardless of the length of matched prefixes. | |
