摘要： A network switching system comprises a managing device and a first switching device comprising first and second ports. The first port communicates with the managing device. A queue communicates with the second port, stores frames for later output by the second port, and generates a congestion signal when filled above a threshold. A control module directs frames received from the second port to the first port, and selectively sends an outgoing flow control message to the first port when the congestion signal is present.

摘要： It is determined whether a packet is a management-type packet. When it is determined that the packet is a management-type packet, a queue is selected from a plurality of queues corresponding to different priorities, wherein the selected queue corresponds to a defined throughput and/or a defined latency. The packet is enqueued in the selected queue. The packet is transmitted via a port of the network device.

摘要： A network device includes a memory with a first queue and a second queue. A timing module generates a first priority timing signal or a second priority timing signal based on a clock signal. The clock signal is shared between the network device and other network devices in a non-arbitrary network. The network device includes a deblocking shaper or a blocking shaper. The deblocking shaper (i) forwards first protected data from the first queue, and (ii) generates a deblocking signal based on a first frame signal and the first priority timing signal. The blocking shaper (i) forwards one of second protected data and unprotected data from the second queue, and (ii) generates a first blocking signal based on a second frame signal and the second priority timing signal. A selector module selects the first frame or the second frame based on the deblocking signal and the first blocking signal.
