public class UnreliableIP

extends SSF.OS.IP

This class is a replacement for SSF.OS.IP, from which the basic functionality is inherited. UnreliableIP adds the possibility to drop all packets which are received or should be sent on a given interface at a given time. This behavior can be used to simulate broken links.

Inner Class Summary

config

public void config(com.renesys.raceway.DML.Configuration cfg)
            throws com.renesys.raceway.DML.configException

Configure this ProtocolSession

 ProtocolSession[ name ip use SSF.OS.OSPFv2.test.UnreliableIP
         fail[
             from 
             until 
             interface 
         ]
         ...
 ]
 

Overrides:

config in class SSF.OS.IP

push

public boolean push(SSF.OS.ProtocolMessage message,
                    SSF.OS.ProtocolSession fromSession)
             throws SSF.OS.ProtocolException

Handles incoming and outgoing IP-packets. Dependent of the interface and the simulation time, the packets are dropped or simply passed to IP.

Overrides:

push in class SSF.OS.IP
