Class LinkCostMatrix

java.lang.Object
  cgl.narada.protocol.LinkCostMatrix

All Implemented Interfaces:

ProtocolDebugFlags

public class LinkCostMatrix
extends Object
implements ProtocolDebugFlags

The link cost matrix maintains the cost associated with traversal over any of the edges within the connectivity graph, hosted at a server node. The link cost matrix reflects the communication costs involved in communication with units at disparate levels. These costs are not absolute costs, and simply reflect the relative costs associated with communications between nodes in different units as compared to the communication costs between nodes in a cluster. These costs along with the graph traversal rules aid the calculation of the shortest routes from any node in the connectivity graph to the vertex node.
