public class PacketGenerator

extends IPwithErrorInjection

This is a replacement for the SSF.OS.IP class, which is able to manipulate packets flowing from and to an OSPF session. The way, the packets are manipulated are specified by some predefined test behaviors -- each used in certain test cases of the OSPF test suite.
The session can be configured as follows:

   ProtocolSession [ name ip use SSF.OS.OSPF.test.PacketGenerator
       debug <no|log|error|all>
       test [
           interface <id>
           behavior <behavior-id>
       ]
   ]
 

Each interface of the router may have one behavior associated with it in a separate test attribute. The behavior-id can be one of the following:

• default: Normal OSPF behavior.
• old_lsa_rcpt: Handling of the receipt of old LSAs (Test 2.6)
• nbr_state_too_low: Correct handling of LSRequests from neighbors in a state lesser than EXCHANGE (Test 2.7)
• dd_retransmit1-4: Retransmission of database description packets (Test 2.8)
• event_seq_number_mismatch1-8: Verify the generation of the SequenceNumberMismatch event (Test 2.9)
• lsa_request_reransmit1-2: Retransmission of LSRequest packets (Test 2.17)
• event_bad_ls_req1-2: Correct handling of the BadLSReq event (Test 2.18)
• remove_lsa_from_retransmission_list: Removing LSAs from the retransmission list, when they are discarded from the link state database (Test 2.21)
• ls_sequence_number_wrap: Correct behavior, when the LS sequence number wraps (Test3.22)

For a more detailed description of the tests, see the additional documentation of the test package.

Inner Class Summary

(package private) class	PacketGenerator.BehaviorTimer This is a generalized timer class, which can be used to execute delayed actions for a specific test behavior.
(package private) class	PacketGenerator.NeighborState these attributes contain information about the actual state of the adjacency, which triggers certain special behaviors

Method Detail

config

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