A multimedia streaming service uses TCP, UDP, SCTP, and QUIC for different components of its network communication during a live broadcast. The service architecture is designed to optimize the streaming of video data, control signals, user data, and real-time gaming commands.Transmission Details:UDP is used for real-time gaming commands, with 11 commands transmitted every second. Each UDP datagram has a payload of 500 bytes and a header of 8 bytes. TCP is employed for sending control signals with a transmission rate of 9 signals per second. Each TCP segment contains a payload of 1000 bytes and a header of 20 bytes. SCTP is chosen for transmitting user data, with 2 messages sent per second. Each message is divided into 4 chunks, with each chunk containing a payload of 500 bytes (2000 bytes total) and a 16-byte chunk header. QUIC is used for video data, sending 24 frames per second. Each QUIC packet holds a payload of 1500 bytes and a header of 32 bytes. Task:Calculate the total amount of data (in bytes) transmitted during a 7-second session across all protocols, accounting for both payload and header sizes for each type of data packet.
