Re: [A3|Milestone 4] Sending replies
Thread.sleep(1) means basically that you are trying to send 1000 messages/sec. Depending on the speed of your computer, this might already be close to the limit. Maybe use something like Thread.sleep(10). The problem is, that if our TestSender-Application send it's messages to fast, our handler does...

Re: no default stark defined error
This usually happens when the configuration file cannot be found. - Make sure that the configuration file is in the current working directory when you start your program. - When you call Mundo.setConfigFile(), do not add the extension '.xml'. For example, to use 'sender.conf.xml', call Mundo.setConf...

Re: Trace files...
You don't have to implement more regarding NetMon. However, your receiver program should
- directly determine the loss rate and print it to the console
- check that no messages were duplicated
- check that the contents of all messages are correct

Re: Indeterminism?!?
MundoCore passes three or four control messages at connection setup. If DropHandler or your handler drops or damages a control message, such indeterminism may occur. If your handler already works "almost everytime", you do not have to read on. To solve this issue, update to mundocore-java-0.9.3 from...

Re: Assignment 3 - packet loss
The receiver should print out the loss rate observed at the receiver. If only a DropHandler is in the stack, then the measured loss rate should pretty much correspond with the loss rate set at DropHandler. If I add your FECHandler to the stack, then I should see that the measured loss rate goes down...

Re: Assignment 3 - questions
MundoCore reads its configuration from node.conf.xml by default. You can call, e.g., Mundo.setConfigFile("receiver.conf"); (The extension .xml will be appended automatically!) to use an alternate configuration file. The last example uses two separate configuration files to define different protocol ...

Re: [A3] The bowels of a Message
(1) Use a stack like shown on Slide 36. We assume that SampleHandler1 is your handler. The BinCollectHandler above your handler will collect everything that should be transported to the remote peer into the chunk "all:bin". For that reason, you only need to care about "all:bin". To read/write your o...
