WebFigure 1: An intuitive example of backpressure routing on a four-node line network with FIFO queueing service. Three packets (in black) are injected at nodes 1 and 2 at time B, intended for the destination sink S. Lyapunov Networking framework ([14], [22], [23], [26]), can be shown to be control decisions resulting in a back-pressure routing ... Backpressure routing is designed to make decisions that (roughly) minimize the sum of squares of queue backlogs in the network from one timeslot to the next. The precise mathematical development of this technique is described in later sections. This section describes the general network model and the operation of backpressure routing with respect to this model. Consider a multi-hop network with N nodes (see Fig. 1 for an example with N = 6). The network …

WebJun 13, 2011 · Note that FIFO-backpressure would achieve a [O(1/V ), O(V )] utility-delay tradeoff since packets need to traverse a whole queue in order to get transmitted. ... WebFor example, you can model the back pressure signal, Ready. The AXI4-Stream interface communicates in master/slave mode, where the master device sends data to the slave device. ... For example, you can use the Ready signal when you use a FIFO block to collect a frame of incoming streaming data, which is then processed with your algorithm.
