Data Communication & Computer Networks Projects

Project 1: Socket Programming

  • Implement FTP using Socket to send and receive data
  • Functions: PUT, GET, LIST
Usage
  • Server: ./myftpserver
  • Client: ./myftpclient <SERVER_IP> <LIST|GET|PUT> <FILE_TO_GET|FILE_TO_PUT>

Project 2: Erasure Coding Scheme and Multiplexing FTP

  • Enhanced FTP with erasure coding scheme for data recovery
  • Monitor multiple servers and clients without blocking by select() and multiple thread
  • Functions: PUT, GET, LIST
Usage
  • Server: ./myftpserver serverconfig.txt
  • Client: ./myftpclient clientconfig.txt <list|get|put>

Project 3: NAT

  • Build an NAT program to forward UDP traffic
  • Provide multiple classes of service to difference classes of traffic by Token Buckets
  • Environment:
    • VM A: 2 network interfaces
      • eth0: Virtual, internal network
      • eth1: Department network
    • VM B, VM C: 1 network interfaces
      • eth0: VIrtual, internal network
  • Monitor packets on the NFQUEUE
  • Identify packets matching the criteria by looking up or create NAT entries
  • Modify the packets, i.e. recalculate checksum
  • Decide whether to accept or reject packets
Usage
  • ./nat <IP_Addr> <Ethernet_LAN> <Subnet_MASK> <BUCKET_SIZE> <FILL_RATE>
