System and method for management of network links by traffic type

摘要

A system and method for management of a network link includes a switching device that includes a control unit and a port coupled to the control unit. The port couples the switching device to a partner switching device using a network link. The control unit is configured to receive a first packet over the network link from the partner switching device and determine whether the first packet includes a first traffic type state separation (TTSS) field. When the first packet includes the first TTSS field, the control unit is configured to determine a first network link state for the network link for a first traffic type and a second network link state for the network link for a second traffic type. Otherwise, the control unit is configured to determine a combined network link state for the network link that applies to both the first and the second traffic types.

1. A network switching device comprising:
a control unit; and a port coupled to the control unit and configured to couple the network switching device to a partner network switching device using a network link; wherein the control unit is configured to:
receive a first management packet over the network link from the partner network switching device;determine whether the first management packet includes a first traffic type state separation (TTSS) field, the first TTSS field including a first actor collector status value indicating that the partner network switching device is ready to receive network traffic of a first traffic type on the network link and a first actor distributor status value indicating that the partner network switching device is ready to transmit network traffic of the first traffic type on the network link;when the first management packet includes the first TTSS field:
determine a first network link state for the network link for the first traffic type by determining whether the network switching device may transmit network traffic of the first traffic type to the partner network switching device on the network link based on the first actor collector status value and whether the network switching device is ready to transmit network traffic of the first traffic type and determining whether the network switching device may receive network traffic of the first traffic type from the partner network switching device on the network link based on the first actor distributor status value and whether the network switching device is ready to receive network traffic of the first traffic type;determine a second network link state for the network link for a second traffic type different from the first traffic type; and exchange network traffic of the first traffic type with the partner network switching device based on the first network link state.
