Class PAL

java.lang.Object
PAL
public class PAL
extends java.lang.Object

Order PAL class used for PAL for an ordered algorithm. The class will use the data center to perform calculation on those.

PAL class will implement the Algorithm 1, 2, 3, and traffic aware for both ordered and unordered policy.

  • Method Details

    • costInOrdered

      public double costInOrdered()

      Implement Ordered PAL Algorithm 1 in paper.

      Returns:
      the total communication cost in PAL of a data center.

    • ascendingOrderedOfCommunicationFre

      public int[] ascendingOrderedOfCommunicationFre()

    • ultilityTrafficAwareOrdered

      public double ultilityTrafficAwareOrdered()

      Traffic Aware utility in ordered policy.

      This will place VM pairs (in ascending order of their communication frequency) to a physical machine that are closest to the ingress(first Middle Box).

      Returns:
      total communication cost in traffic aware ordered policy of a data center.

    • PALUnordered

      public double PALUnordered()

      Implement the algorithm 3 in the paper.

      Returns:
      total communication cost in unordered PAL algorithm in data center.

    • utilityTrafficAwareUnordered

      public double utilityTrafficAwareUnordered()

      Implement the total communication cost in unordered PAL Traffic Aware.

      Returns:
      total communication cost in unordered PAL Traffic Aware.
