      Conference report
      Restricted access - publisher's policy
      Compact routing schemes address the fundamental tradeoff between the memory space required to store the routing table entries and the length of the routing paths that these schemes produce. This paper introduces the first ...
    • Internet routing paths stability model and relation to forwarding paths
