Section 3.8

Question 1

What are advantages of the streams concept in QUIC?

Answer 1

1.Since each stream has its own error control, if one stream experiences an error (e.g., lost or damaged segment), the other streams are unaffected
2.
Streams allow concurrent retrieval of web objects, while avoiding Head of the Line (HOL) blocking

Question 2

What are advantages of implementing transport-layer functionality in QUIC at the application layer?

Answer 2

1. QUIC can establish all connection parameters (security, reliability, flow and congestion control)in just one handshake rather than separately in two
2. As an application-layer protocol, QUIC can be updated/modified at “app frequency” rather than at the frequency of operating system updates.
