ABSTRACT:
A method for providing quality of service (QoS) for an Internet Small Computer System Interface (iSCSI) environment is presented. The method includes the steps of shaping one or more Protocol Data Units (PDUs) in an iSCSI initiator according to QoS policies, and marking in a Transmission Control Protocol (TCP) layer at an initiator node the shaped PDUs according to the QoS policies, and wherein the PDUs are command PDUs, wherein the shaping of the command PDUs occurs before assigning command sequence numbers to said command PDUs.
