Filed:

Aug 2, 2012

Appl. No.:

13/564985

Inventors:

Michael Lau - Rockville MD, US
Nathan Shumway Hill - Milpitas CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

G06F 15/173

US Classification:

709225

Abstract:

A method and network device provides port scheduling for data ports in the network device. The network device may assign data ports of the network device into port groups according to port characteristics of the data ports. The network device may schedule processing time slots for active data ports by determining a selected port group based on group selection parameters. The network device may then determine a selected data port from the selected port group using port selection criteria. The port selection criteria may maintain minimum and maximum packet spacing requirements for the data ports of a port group. The network device may also maintain an active ports list to disqualify inactive data ports from selection.

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.
