public class IPwithErrorInjection

extends UnreliableIP

This class is a replacement for SSF.OS.IP. Basic functionality is provided by IP and UnreliableIP, which provides the facility to bring down links at given times. This class additionally provides the facility to manipulate the contents of OSPF packets at given times. More details are provided in the additional documentation of the OSPF testsuite.

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 UnreliableIP.

Overrides:
