packet scheduler


Also found in: Acronyms, Wikipedia.

packet scheduler

A function at the network protocol level that allocates bandwidth to competing online connections. Residing in the transmitting machine, it determines how many packets are handed to each connection (each flow) at a given time. A packet scheduler makes its determinations by observing the packet flows from the applications or by request from a quality of service (QoS) protocol such as RSVP or Diffserv. See QoS.

In our proposed system model, the video blocks are dispatched into several paths by the packet scheduler. The controller computes the available bandwidth and the RTT of each path for each flow, and dispatches the packets into the paths based on scheduling algorithm MARS.
