Abstract
Disclosed is a network communication switch that facilitates reliable communication of high priority traffic over lower priority traffic across all ingress and egress ports. The network communication switch may monitor the frame storage buffer regardless of egress port, and when the frame storage buffer reaches a predetermined level, the switch may discard lower priority frames from the most congested port. When the frame storage buffer reaches a second predetermined level, the switch may discard lower priority frames before they are stored according to egress port. The network communication switch may further monitor ingress frames for priority, and assign priority to frames according to pre-assigned priority, ingress port, and/or frame contents.
