The tail-drop queue-limit must be hit before the LOCP packets are dropped. All LOCPs with the discard priority set are by default put into an implicitly allocated high priority queue of each physical egress interface. By default, all LOCPs that have the discard pr...

Because access to the network is serial by node and because the only server in the system is the network itself, we can consider allmessage packetarrivals to the server as originating from a single queue. Thus, this single conceptual queue contains the combination of all messages in the indivi...
USB supports two types of transfers: stream and message. A stream has no defined structure, whereas a message does. At start-up one message pipe, Control Pipe 0, always exists as it provides access to the device’s configuration, status andcontrol information. ...
