Packet Classification by Multilevel Cutting of the Classification Space: An Algorithmic-Architectural Solution for IP Packet Classification in Next Generation Networks

Algorithm 2

Get number of cuts for each selected dimension.

Initialize max No. of cuts to a predefined value

Initialize max % of empty nodes to a predefined value

No. of cuts = 1

Loop

  No. of empty nodes = 0

  Loop on cuts

    Get the range to search in

    No. of rules in this cut = 0

    Loop on rules

     If rule is in the range then increment the No. of rules in this cut

     If No. of rules is this cut is 0 then increment the No. of empty nodes

  Calculate the % of empty nodes to total nodes

  If (% $>$ max % or empty nodes $\setminus \setminus$ number of cuts $\ge$ max number of cuts)

    break

  else

    double the number of cuts
