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
