* `fixed`: maintains a fixed-size window of Interests in flight; the window size is configurable
via a command line option and defaults to 1.
-* `aimd` : sends Interests using an additive-increase/multiplicative-decrease (AIMD) algorithm to
- control the window size. By default, a Conservative Loss Adaptation algorithm is adopted
- combining with the AIMD algorithm, that is, at most one window decrease will be
- performed per round-trip-time. For details please refer to:

+* `aimd` : adjusts the window size via additive-increase/multiplicative-decrease (AIMD).
+ By default, it uses a Conservative Window Adaptation, that is, the congestion window
+ will be decreased at most once per round-trip-time.
-The default Interest pipeline type is `aimd`.
+* `cubic`: adjusts the window size similar to the TCP CUBIC algorithm.
