      Midthaug, Ingvild Hovdelien (Master thesis, 2018)
      Nowadays the global amount of digital data increases rapidly. Internet-connected devices generate massive amounts of data through various interactions such as digital communication and file sharing. In a world surrounded ...
    • HashTag Erasure Codes: From Theory to Practice 

      Kralevska, Katina; Gligoroski, Danilo; Jensen, Rune Erlend; Øverby, Harald (Journal article; Peer reviewed, 2018)
      Minimum-Storage Regenerating (MSR) codes have emerged as a viable alternative to Reed-Solomon (RS) codes as they minimize the repair bandwidth while they are still optimal in terms of reliability and storage overhead. ...
    • Network Traffic Driven Storage Repair 

      Gligoroski, Danilo; Kralevska, Katina; Jensen, Rune Erlend; Simonsen, Per (Journal article; Peer reviewed, 2019)
      Recently we constructed an explicit family of locally repairable and locally regenerating codes. Their existence was proven by Kamath et al. but no explicit construction was given. Our design is based on HashTag codes that ...
