Class Link

java.lang.Object
  edu.colorado.cs.ns2.sim.Link

All Implemented Interfaces:

java.io.Serializable

public class Link
extends java.lang.Object
implements java.io.Serializable

This class implements the NS2 notion of a Link. A Link provides a means by which to physically connect two nodes. Links are defined by the nodes that they connect, a queuing model, a bandwidth, latency, and optional queue arguments.
