Figure 1: Illustration of the model. The top panel depicts the number of flows 𝑁 𝑡 as a function of time, the middle panel the rate allocated to each source as a function of time, and the bottom panel the workload 𝑊 𝑡 as a function of time; we have chosen 𝑊 = 3 / 2 . Note that when 𝑁 𝑡 = 1 the rate per source equals 𝐶 / 2 when the buffer is empty, and 2 𝐶 / 5 when the buffer is nonempty. Also note that the queue builds up when 𝑁 𝑡 2 .
