METHOD AND APPARATUS FOR BLOCKING TRANSMISSION OF FRAMES FROM A NETWORK DEVICE

摘要

A network device including first and second queues, a timing module and a shaper. The first queue receives first frames. The second queue receives second frames. A priority level of the second frames is lower than a priority level of the first frames. The timing module determines a start time of a burst period of the first frames. The first frames are transmitted from the network device during the burst period. The shaper determines: a size of a head-of-line frame of the second frames; a predetermined maximum size of one of the second frames; or a predetermined minimum size of one of the second frames. The shaper determines whether to block transmission of the head-of-line frame from the network device based on (i) the start time, (ii) the size of the head-of-line frame, (iii) the predetermined maximum size, or (iv) the predetermined minimum size.

主权项

1. A network device comprising:
a first queue to receive a first plurality of frames, wherein the first plurality of frames have a first priority level; a second queue to receive a second plurality of frames, wherein the second plurality of frames have a second priority level, and wherein the second priority level is lower than the first priority level; a timing module to determine a start time of a burst period of the first plurality of frames, wherein the first plurality of frames are transmitted from the network device during the burst period; and a shaper to determine (i) a size of a head-of-line frame of the second plurality of frames, (ii) a predetermined maximum size of one of the second plurality of frames, or (iii) a predetermined minimum size of one of the second plurality of frames, wherein the shaper is further to determine whether to block transmission of the head-of-line frame from the network device based on (i) the start time, (ii) the size of the head-of-line frame, (iii) the predetermined maximum size, or (iv) the predetermined minimum size.
