Problem 7. (9 points) This question comes from Lecture-19's reading assignment "The Evolution of Distributed Dataset Synchronization Solutions in NDN" (so you must read the paper:). Please keep your answer short. 7.1 (3 points) Section 2 states that, as a transport protocol, TCP provides 3 basic functions. Which of these 3 functions does NDN's transport perform? 7.2 (3 points) Both syncps and PSync uses IBF to encode the dataset names, but they do so in different ways. Please explain how syncps encodes data names and how PSync does it. 7.3 (3 points) What are the top 2 differences between the designs of PSync and SVS (State Vector Sync)?
