inputOutputHandler
Class NextMixConnectionHandler

java.lang.Object
  java.lang.Thread
      inputOutputHandler.NextMixConnectionHandler

All Implemented Interfaces:

java.lang.Runnable

final class NextMixConnectionHandler
extends java.lang.Thread

Handles communication with the next mix in the cascade.

Establishes a (TCP) connection with the next mix which is used to transmit messages (Requests and Replyies) of all users connected to the cascade's fist mix (multiplex channel).

(De-)multiplexes Requests/Replyies using an (encrypted) header (see generateInterMixHeader()).

Replyies are put in the InputOutputHandlerController's replyInputQueue (see InputOutputHandlerController.addUnprocessedReply()). Requests are taken from the InputOutputHandlerController's requestOutputQueue (see InputOutputHandlerController.getProcessedRequest()).

Note: Authentication is NOT implemented!
