  • Method and system for congestion management in a fibre channel network
    Patent number: 9342339
    Abstract: 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.

  • Method and system for facilitating application-oriented quality of service in a fibre channel network
    Patent number: 8923328
    Abstract: 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.

  • Port trunking at a fabric boundary
    Patent number: 8223633
    Abstract: F_PORTs of an edge switch are logically trunking with N_PORTs of a node device outside the fabric via a trunked group of communications links. The trunked N_PORTs of the node device and the trunked F_PORTs of the edge switch are configured to send and receive frames of a particular stream across the multiple trunked links for in-order communication with the other device. The node device outside the fabric initially negotiates with the edge switch using a sequence of fabric login requests and fabric login acceptances to establish the trunked connection between the devices (and their respective ports).
