Abstract

Systems, methods and software useful for overcoming network congestion problems including head-of-line blocking issues and other network congestion problems. In certain aspects, flow control mechanisms implemented in a switch device or other network device manage buffer and system level resources using a scheduler to control the amount of data requested from a local SAN fabric. Switches and other network devices configured according to the present invention monitor each individual SCSI task, and are configured to apply flow control measures to each active session when buffering resources become scarce, such as when buffering data for a slower-speed WAN link or TCP/IP based interconnects of any speed.
