Port Trunking At A Fabric Boundary

View page
US Patent:
8223633, Jul 17, 2012
Filed:
Oct 3, 2008
Appl. No.:
12/245269
Inventors:
Rajnish Gupta - Bangalore, IN
Nhan T. Pham - Fremont CA, US
Amod K. Dani - Bangalore, IN
Ponpandiaraj Rajarathinam - San Jose CA, US
Vineet Mathew Abraham - Sunnyvale CA, US
Assignee:
Brocade Communications Systems, Inc. - San Jose CA
International Classification:
G01R 31/08
H04L 12/28
G06F 15/177
G06F 11/00
US Classification:
370228, 370389, 370409, 709220, 714 43
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).

Partitioning Of Switches And Fabrics Into Logical Switches And Fabrics

US Patent:
20110085557, Apr 14, 2011
Filed:
Oct 8, 2009
Appl. No.:
12/575603
Inventors:
Sathish Kumar Gnanasekaran - Sunnyvale CA, US
Badrinath Kollu - San Jose CA, US
Richard L. Hammons - Hollister CA, US
Ramkumar Vadivelu - San Jose CA, US
Dan Norbert Retter - Cupertino CA, US
Jianqiang Zhou - Milpitas CA, US
Ponpandiaraj Rajarathinam - Sunnyvale CA, US
Daniel Ji Yong Park Chung - San Jose CA, US
Assignee:
BROCADE COMMUNICATIONS SYSTEMS, INC. - San Jose CA
International Classification:
H04L 12/56
US Classification:
370401
Abstract:
A Layer network switch is partitionable into a plurality of switch fabrics. The single-chassis switch is partitionable into a plurality of logical switches, each associated with one of the virtual fabrics. The logical switches behave as complete and self-contained switches. A logical switch fabric can span multiple single-chassis switch chassis. Logical switches are connected by inter-switch links that can be either dedicated single-chassis links or logical links. An extended inter-switch link can be used to transport traffic for one or more logical inter-switch links. Physical ports of the chassis are assigned to logical switches and are managed by the logical switch. Legacy switches that are not partitionable into logical switches can serve as transit switches between two logical switches.

US Patent:
8160072, Apr 17, 2012
Filed:
Dec 11, 2009
Appl. No.:
12/636591
Inventors:
Sathish K. Gnanasekaran - Sunnyvale CA, US
Ponpandiaraj Rajarathinam - Sunnyvale CA, US
Vineet M. Abraham - Sunnyvale CA, US
Assignee:
Brocade Communications Systems, Inc. - San Jose CA
International Classification:
H04L 12/28
US Classification:
370392, 370229, 370389, 370235, 370468
Abstract:
One embodiment of the present invention provides a system that facilitates end-to-end quality of service (QoS) between a source and a destination in a network. During operation, the system allocates virtual channels on an output port of a switch to a number of quality of service (QoS) levels. The system further assigns a virtual channel to a traffic flow based on a QoS zone, wherein the QoS zone is identified by a host identifier, a target identifier, and a QoS level of the traffic flow. In addition, the system forwards data frames in the traffic flow via the assigned virtual channel.

International Classification:
H04L 12/713
H04L 12/775
H04L 12/721
Abstract:
A Layer 2 network switch is partitionable into a plurality of switch fabrics. The single-chassis switch is partitionable into a plurality of logical switches, each associated with one of the virtual fabrics. The logical switches behave as complete and self-contained switches. A logical switch fabric can span multiple single-chassis switch chassis. Logical switches are connected by inter-switch links that can be either dedicated single-chassis links or logical links.

Method And System For Facilitating Quality Of Service In Edge Devices In A Fibre Channel Network

US Patent:
20140204957, Jul 24, 2014
Filed:
Mar 20, 2014
Appl. No.:
14/221134
Inventors:
- San Jose CA, US
Ramkumar Vadivelu - San Jose CA, US
Vinodh Ravindran - San Jose CA, US
Ponpandiaraj Rajarathinam - Sunnyvale CA, US
Assignee:
BROCADE COMMUNICATIONS SYSTEMS, INC. - San Jose CA
International Classification:
H04L 5/00
US Classification:
370431
Abstract:
One embodiment of the present invention provides a system that facilitates quality of service (QoS) in a Fibre 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.
