Sliding Window Protocol 6

This repo aims to enhance my understanding of the network protocol hierarchy and flow control and error control techniques by implementing a sliding window protocol in a simulated communication network system. The programming language will be Java.

Source Files

Two java source files are provided:

.
├── SWP.java        # The skeleton of the Sliding Window Protocol component. Note: this is the only provided java source file that you can change. You may add new java classes in order to fully implement the sliding window protocol.
└── PFrame.java     # The frame class source file. Note: this java source file is provided for your reference in implementing sliding window protocol, but you should not change anything in this file.

Class Files

A number of java class files are provided, which implement the Network Simulator component and the Sliding Window Environment component:

.
├── NetSim.class                               # the main class of the Network Simulator component.
├── Forwarder.class                            # an auxiliary thread class of the NetSim component.
├── VMach.class                                # the main class of the Virtual Machine component
├── SWE.class                                  # the major class of the Sliding Window Environment component.
├── FrameHanlder.class                         # an auxiliary thread class of the SWE component.
├── NetworkSender.class                        # an auxiliary thread class of the SWE component.
├── NetworkReceiver.class                      # an auxiliary thread class of the SWE component.
├── EventQueue.class                           #an auxiliary class of the SWE component.
├── Packet.class                               # an auxiliary class of the SWE component.
├── PacketQueue.class                          # an auxiliary class of the SWE component.
├── PEvent.class                               #  an auxiliary class of the SWE component.
├── PFrame.class                               # an auxiliary class of the SWE component
└── PFrameMsg.class                            # an auxiliary class of the SWE component.

Testing Text Files

Two text files are provided for testing purpose. They are used by the Sliding Window Environment component to generate a sequence of packets to be sent to the other communicating machines:

.
├── send_file_1.txt                              # the file is used by VMach 1 to generate a sequence of (text) packets to VMach 2
└── send_file_2.txt                              # the file is used by VMach 2 to generate a sequence of (text) packets to VMach 1.
