Patent number: 9524182Abstract: One embodiment of the present invention provides a system that facilitates quality of service (QoS) in a Fiber 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.Type: GrantFiled: December 19, 2014Date of Patent: December 20, 2016Assignee: BROCADE COMMUNICATIONS SYSTEMS, INC.Inventor: Amit Kanda

Patent number: 9342339Abstract: One embodiment of the present invention provides a system that facilitates congestion management in a Fibre Channel (FC) network. During operation, the system determines a threshold data rate on an outgoing link coupled to an FC switch. The system further determines the number of sources that send data to the outgoing link and an aggregate arrival rate of data for the outgoing link. Next, the system determines an injection data rate for a respective source based on the threshold data rate on the outgoing link, the number of sources transmitting data to the outgoing link, and the aggregate arrival data rate for the outgoing link. Subsequently, the system communicates the injection data rate to the source, thereby allowing the source to throttle its data injection in the FC network to prevent network congestion.Type: GrantFiled: May 12, 2008Date of Patent: May 17, 2016Assignee: BROCADE COMMUNICATIONS SYSTEMS, INC.Inventors: Amit Kanda, Sathish Kumar Gnanasekaran, Vineet Mathew Abraham, Qingyuan Ma

Patent number: 9158570Abstract: One embodiment of the present invention provides a system that facilitates quality of service (QoS) in a Fiber Channel (FC) host bus adaptor (HBA). In this system the bandwidth on an FC link between the HBA and the FC switch can be allocated into a plurality of logical channels, and a respective logical channel can transport data frames of variable length. Furthermore, a respective logical channel is associated with a dedicated buffer. During operation, the HBA communicates to an FC switch the HBA's capability of receiving or sending a data flow over a logical channel that couples the HBA to the FC switch. The HBA further receives logical-channel allocation information from the FC switch. Furthermore, the HBA associates data frames with a logical channel and transmits data frames to the FC switch on the corresponding logical channel.Type: GrantFiled: March 20, 2014Date of Patent: October 13, 2015Assignee: BROCADE COMMUNICATIONS SYSTEMS, INC.Inventors: Amit Kanda, Ramkumar Vadivelu, Vinodh Ravindran, Ponpandiaraj Rajarathinam

Patent number: 9146768Abstract: One embodiment of the present invention provides a system that facilitates automatic adjustment of logical channels in a Fiber Channel (FC) network. During operation, the system receives FC data frames. A respective data frame is associated with a logical channel. The bandwidth on an FC link can be allocated into a plurality of logical channels, and a respective logical channel is associated with a dedicated buffer and can transport a plurality of data flows with data frames of variable length. The system then identifies a slow data flow in a first logical channel. Next, the system assigns the slow data flow to a second logical channel, thereby preventing the slow data flow from slowing down other data flows in the first logical channel. The system subsequently forwards the data frames in the slow data flow on the second logical channel onto an outgoing link.Type: GrantFiled: March 20, 2014Date of Patent: September 29, 2015Assignee: BROCADE COMMUNICATIONS SYSTEMS, INC.Inventors: Amit Kanda, Kung-Ling Ko

Patent number: 9054972Abstract: A port monitor monitors network traffic that passes through a port of a switch. Frame flows routed through the switch are counted by hardware frame counting logic, which includes a content-addressable memory (CAM) and counters corresponding to various frame flows. Port monitor software includes logical containers (“buckets”), which are used to record and sort counts of the frame flows from hardware based on activity of the frame flows. Frame flow sorting is based on confidence building algorithms such that the thrashing of frame flows between buckets is reduced. Storage and sorting of the frame flows in software allows the activity level of any number of frame flows associated with the switch to be counted, regardless of hardware limitations on how many frame flows can be counted. This allows a real-time analysis of frame flows and a determination of frame flows that are major users of Fiber Channel bandwidth.Type: GrantFiled: October 11, 2013Date of Patent: June 9, 2015Assignee: Brocade Communications Systems, Inc.Inventors: Amit Kanda, Sathish Kumar Gnanasekaran

Patent number: 8949392Abstract: A workload management system identifies a first source device and first destination device which can be used to perform a job function. The system further communicates information about the first source device and destination device to one or more switches, and receives a set of network parameters along a data path from the first source device to the first destination device. The system then determines resources available on the first source device and/or first destination device. In addition, the system determines whether the first source device and first destination device, if used for the job function, can satisfy a set of SLAs for that job function based on the network parameters along a data path from the first source device to the first destination device and the determined resources available on the first source device and/or first destination device.Type: GrantFiled: May 12, 2008Date of Patent: February 3, 2015Assignee: Brocade Communications Systems, Inc.Inventor: Amit Kanda
