An ingress fabric endpoint coupled to a switch fabric within a network device reorders packet flows based on congestion status. In one example, the ingress fabric endpoint receives packet flows for switching across the switch fabric. The ingress fabric endpoint assigns each packet for each packet flow to a fast path or a slow path for packet switching. The ingress fabric endpoint processes, to generate a stream of cells for switching across the switch fabric, packets from the fast path and the slow path to maintain a first-in-first-out ordering of the packets within each packet flow. The ingress fabric endpoint switches a packet of a first packet flow after switching a packet of a second packet flow despite receiving the packet of the first packet flow before the packet of the second packet flow.

Aspects of recovery of an application from an error. An error notification is received from an agent associated with an application, the error notification being indicative of an error encountered during execution of the application. The error notification is compared with error patterns stored in a database to determine a matching error pattern. Further, a recovery action is ascertained and the recovery action is provided to the agent to recover the application from the error.

Recovery of application from error

A network device includes a memory, a plurality of packet processors, a switch fabric coupling the plurality of processors, and processing circuitry. The processing circuitry is configured to receive a data stream to be transmitted on a switch fabric and determine a plurality of credit counts, each credit count being assigned to a respective subchannel of a plurality of subchannels. The packet processor is further configured to determine per-subchannel occupancy of the memory for the plurality of subchannels, select, based on the plurality of credit counts and the per-subchannel occupancy of the memory, a subchannel of the plurality of subchannels for transmitting a cell of a plurality of cells for the data stream, and output data for the cell to the memory for output by the selected subchannel.
