CSE 489/589: Modern Networking Concepts (Fall 2010)

Programming Project 1

• Project 1 specification
• Grading criteria
• The binaries of my implementation of project 1 (for you to test yours against):
• Mac OS X version release 0.8
• Linux version release 0.8
• Sun OS version release 0.8
• There are 4 sample programs you should study carefully. To extract the source files of any example, gunzip filename.tar.gz and then tar -xvf filename.tar. Then, cd into the untared directory and type make to compile the programs. Read the README files in each directory, and also the comments inside the source codes to see what's going on. (To check your machine's IP, use ifconfig as I've shown in class.)
  • TCP Echo Client & Server: there are actually two clients: client is plain with many design flaws, iom_client uses IO multiplexing with select that fixes a flaw from client. Server is multi-processing (it forks a new process to handle a new request)
  • UDP Echo Client & Server
  • A Generic Server Using IO Multiplexing (Generic means it can handle both UDP and TCP; clients are either TCP or UDP above)
  • Generic TCP/UDP Using Multi-threading (the clients are either TCP or UDP above)

Helpful resources for your project

• Organizing code files in C and C++ (this is a bit too lengthy). Structuring header files is short and sweet
• A short makefiles tutorial (this should be sufficient for our purpose)
• A nice CVS tutorial
• Pthread tutorial
• C Programming by Steve Holmes
• Beej's Guide to Network Programming
• Introduction to Unix Signal Programming
• An Introductory 4.4BSD IPC Tutorial (Postcript File)
• GNU Make manual
• You can also check out some more advanced documents (these are not absolutely needed for project 1, read them if you have time)
  • Advanced BSD IPC tutorial
  • CVS tutorial
