Abstract

Linear codes with locality r and availability t have a wide application in distribution storage because they permit local repair and parallel accesses of hot data. In this letter, the locality and availability of some linear codes based on finite geometry are given. According to these results, we give some linear codes that have higher rate than known codes with the same locality and availability.
