Path Protocol Test8RECOMMENDATION FOR ADVANCED ORBITING SYSTEMSThis test injects packets into path from the subnetwork and checks that they emerge on the localnode and are re-transmitted if necessary.It demonstrates the path layer's ability to handle multiple paths.Run the test using the command:ts pp.t8.lot pp.lotType START at the hippo prompt (after some time) and then select ppt8 from the menu. Stepthrough the events offered using the NEXT command of hippo. Eventually the success eventshould take place and the next NEXT command will result in deadlock.The choice taken when multiple events are offered is not important for the success of this test;the exception to this is that the success event should not be chosen unless no alternative exists.This is just a holder for the test behaviour:process ppt8 (pType : PacketType,dataLossFlags : Bool) : noexit :=(hide pkt, oct, man, snw in(test[pkt, oct, man, snw]|[pkt, oct, man, snw]|PathProtocol[pkt, oct, man, snw] (pType, False)))whereThis is the test behaviour itself:process test[pkt,oct,man,snw] : exit :=hide success, failure in(CCSDS HISTORICAL DOCUMENTSet up the paths through the management gate:man !
