摘要： A switching network includes an upper tier having a master switch and a lower tier including a plurality of lower tier entities. The master switch, which has a plurality of ports each coupled to a respective lower tier entity, implements on each of the ports a plurality of virtual ports each corresponding to a respective one of a plurality of remote physical interfaces (RPIs) at the lower tier entity coupled to that port. Data traffic communicated between the master switch and RPIs is queued within virtual ports that correspond to the RPIs with which the data traffic is communicated. The master switch applies data handling to the data traffic in accordance with a control policy based at least upon the virtual port in which the data traffic is queued, such that the master switch applies different policies to data traffic queued to two virtual ports on the same port of the master switch.

摘要： A switching network has a plurality of switches including at least a switch and a managing master switch. At the managing master switch, a first capability vector (CV) is received from the switch. The managing master switch determines whether the first CV is compatible with at least a second CV in a network membership data structure that records CVs of multiple switches in the switching network. In response to detecting an incompatibility, the managing master switch initiates an image update to an image of the switch. In response to a failure of the image update at the switch, the switch boots utilizing a mini-DC module that reestablishes communication between the switch with the managing master switch and retries the image update.

摘要： A technique for executing normally interruptible threads of a process in a non-preemptive manner includes in response to a first entry associated with a first message for a first thread reaching a head of a run queue, receiving, by the first thread, a first wake-up signal. In response to receiving the wake-up signal, the first thread waits for a global lock. In response to the first thread receiving the global lock, the first thread retrieves the first message from an associated message queue and processes the retrieved first message. In response to completing the processing of the first message, the first thread transmits a second wake-up signal to a second thread whose associated entry is next in the run queue. Finally, following the transmitting of the second wake-up signal, the first thread releases the global lock.
