METHOD AND SYSTEM FOR FACILITATING APPLICATION-ORIENTED QUALITY OF SERVICE IN A FIBRE CHANNEL NETWORK

摘要

One embodiment of the present invention provides a system that facilitates quality of service (QoS) in a Fibre Channel (FC) network. During operation, a host bus adaptor (HBA) allocates the bandwidth on an FC link between the HBA and an FC switch into a plurality of logical channels, wherein a respective logical channel can transport data frames of variable length. Furthermore, a respective logical channel is associated with a dedicated buffer on the HBA. The HBA associates data frames from a logical entity associated with the HBA with a logical channel, and transmits data frames from the logical entity to the FC switch on the corresponding logical channel within the link from the HBA to the FC switch.

1. A computing system, comprising:
one or more ports; processing circuitry; a storage device coupled to the processing circuitry and storing instructions which when executed by the processing circuitry cause the processing circuitry to perform a method, the method comprising:
associating a first logical channel with a virtual machine, wherein the first logical channel is associated with a first dedicated buffer to facilitate a class of service, and wherein a first port of the one or more ports accommodates a number of logical channels;assigning a group of logical channels associated with the port to a class of service; andassociating a packet from the virtual machine with the group of logical channels based on the class of service to which the virtual machine is associated.
