• * Physical
• bit-level operations

• * dropped packets
• can solve via retransmission.
• * out of order packets
• tags packet indices to reconstruct order.
• * destination buffer overflow, buffer overflow/dropped packets along route

UDP (User datagram protocol)

• * Provides socket address for application-level multiplexing
• * No flow control or congestion control
• * No retransmission guarantee

TCP (Transmission control protocol)

• * Acknowledgement system for reliability and flow/congestion control
• Infer rate at which packets have been received by returned ACKs
• * Congestion control
• reduce transmission rates when overflows are detected downstream
• * Flow control:
• Control the amount of traffic ingested into the network. This is done through the use of the send-ack protocol.
