Detailed Description

NDN consumer application with more advanced congestion control options.

This app uses the algorithms from "A Practical Congestion Control Scheme for Named Data Networking" (https://dl.acm.org/citation.cfm?id=2984369).

It implements slow start, conservative window adaptation (RFC 6675), and 3 different TCP algorithms: AIMD, BIC, and CUBIC (RFC 8312).
