A video conferencing application requires low latency and high throughput to support real-time communication between participants. Which TCP congestion control mechanism is specifically designed to prioritize low latency over throughput?Question 1Answera.TCP CUBICb.TCP Renoc.TCP Vegasd.TCP BBR

The TCP congestion control mechanism that is specifically designed to prioritize low latency over throughput is d. TCP BBR (Bottleneck Bandwidth and Round-trip propagation time).

Here's a step-by-step explanation:

1. TCP (Transmission Control Protocol) is a standard that defines how to establish and maintain a network conversation through which application programs can exchange data.

2. TCP uses a number of mechanisms to achieve high performance and avoid congestion. These mechanisms include flow control, sequence numbers, acknowledgement messages, and congestion control.

3. Congestion control mechanisms are crucial in ensuring that the network does not become overloaded with too much traffic. They do this by adjusting the rate at which data is sent.

4. TCP CUBIC, TCP Reno, TCP Vegas, and TCP BBR are all different types of congestion control mechanisms.

5. TCP CUBIC and TCP Reno are designed to optimize for maximum throughput, and they do this by aggressively probing the network to find available bandwidth.

6. TCP Vegas also tries to optimize for throughput, but it does so in a more conservative way, by trying to avoid congestion in the first place.

7. TCP BBR, on the other hand, is designed to prioritize low latency over throughput. It does this by continuously estimating the network's bottleneck bandwidth and round-trip propagation time, and adjusting the rate of data transmission accordingly. This makes it an ideal choice for applications like video conferencing, where low latency is crucial for real-time communication.

3. Congestion control mechanisms are critical in ensuring that the network doesn't become overloaded with too much traffic. They work by adjusting the rate at which data is sent in response to changes in network conditions.

4. TCP BBR is a congestion control algorithm developed by Google. It stands for "Bottleneck Bandwidth and Round-trip propagation time".

5. Unlike other TCP congestion control algorithms, BBR does not reduce its sending rate in response to packet loss. Instead, it continuously measures the network's delivery rate and round-trip time and adjusts its sending rate accordingly.

6. This makes BBR particularly well-suited for real-time applications like video conferencing, where low latency is more important than high throughput.
