Transport Layer

Transport Layer

1. TCP

   • Flow Control
     • Go-Back-N
     • Selective Repeat
     • Sender won't overrun receiver by transmitting too much too fast
   • Congestion Control
     • Having too many sources sending too much data, too fast for network to handle
   • Slower, but more reliable

2. UDP

   • Connectionless (No Handshaking)
     • Makes it faster.
   • Faster, but less reliable due to less error detection and correction

3. Error Handling

   • RDT 2.0 / 3.0
     • Checksums
     • Sequence Numbers
   • Round Trip Time and Time Out

4. Multiplexing/De-multiplexing

   • Distinguishing different applications on a machine connected to the internet
