Abstract: A network switch including a set of communication ports is provided. The communication ports may have an allocated prebuffer to store data during packet switching operations. The network switch may further include a calendar associated with the set of communication ports that provides bandwidth configuration for the set of communication ports. The network switch may further include a secondary calendar that may be dynamically setup. The secondary calendar may provide an alternative bandwidth configuration strategy for the set of communication ports. The switch includes circuitry that may increase the prebuffer size and upon the successful increase of the prebuffer size reconfigure the set of communication ports from the original calendar to the secondary calendar, without a reboot. The circuitry may reset the prebuffer size after reconfiguration is complete and the switch may continue operation according to the reconfigured settings.

Abstract: A network device, such as a network switch, can include an ingress to receive data packets from a network. The ingress can communicate with an egress included in the network device though a fabric included in the network device. At least one of ingress and the egress can enqueue a data packet prior to receipt of all cells of the data packet. The ingress can also commence with dequeue of the cells of the received data packet prior to receipt of the entire data packet from the network. At least one of ingress and the egress can process the data packets using cut-through processing and store-and-forward processing. In a case of cut-through processing of a data packet at both the ingress and the egress of a network device, such as CIOQ switch, the fabric can be allocated to provide a prioritized virtual channel through the fabric for the data packet.
