Principles,rinters, servers, and web cams. With the development of the Internet of Things, hundreds of billions of devices will soon be connected via the Internet. By “connect,” we mean that the Internet enables these hosts to transfer files or bit streams among each other. To reduce cost, all these hosts shar

First, TCP is an approximation of a distributed algorithm that maximizes the total utility of the active connections. Second, a new class of “backpressure” protocols optimize the scheduling, routing, and congestion control in a unified way.
