TCP vs. UDPBy: Ryan A Rose
TCP (Layer 4)• Connection-oriented
• SYN, ACK, FIN connections
• Detects loss of messages and retransmits them
• Congestion Control
• Flow Control
UDP (Layer 4)• Simplest protocol – Performance >
Completeness
• Connectionless
• No ACK’S
• No Detect of loss of messages nor retransmits them
• Ensure that data is received in the same order that it was sent
• No congestion control
• No manage of the flow of data
RTP (Application Layer 5-6-7)• AKA RTTP
• “provides end to end transport functions suitable for applications transmitting real time data”
• Not QoS protocol, don’t handle retransmissions
• Not used for setup/teardown
• Can also use real time control protocol to monitor the stream
