They are short or insufficient pieces of information and require additions to further increase the article's usefulness. The project values stubs as useful first steps toward complete articles.

Transport schedule

The schedule of traffic between peers as seen from the global perspective and assuming the simplest situation of all peers needing to communicate with all other peers using the same amount of bandwidth, requires (n2+n)/2 sessions to be booked. A session in this case is meaning the booking a portion of bandwidth for the same period of time on two peers and establishing a bidirectional stream between them for that time.

The central cycle of global activity is the local day/night cycle because that's the dominant cycle determining the timing of information availability. ie that the majority of syncronisation would be occuring at night time.

Nodal Structure

The structure of what's contained within what in the loop tree is determined by the order resulting in least context-switches. In the context of S&D this order is

Root → Resources → Types → Instances → Sessions
