ABSTRACT:
Packets may be routed within a node or a network device using independent input buffers for each interface and a centralized scheduler. By employing a centralized scheduler, the risks of starvation and unfairness may be reduced. Furthermore, a centralized scheduler may be able to track the relative arrival order of all of the packets received by a node or network device, and thus older packets may tend to be routed before younger packets, leading to improved performance. Also, by maintaining independent buffers for each interface, more efficient physical routing may be achieved within a node or network device.
