Patent number: 9887917Abstract: An extended bridge structure that includes a controlling bridge and port extenders is disclosed. A port extender according to some embodiments of the present invention includes a processor that processes receives packets in a way that executes at least one procedure that substitutes for a function of the controlling bridge. A controlling bridge according to the present invention provides data to the port extender that enables it to execute the at least one procedure that substitutes for a function of the controlling bridge.Type: GrantFiled: March 18, 2016Date of Patent: February 6, 2018Assignee: DELL PRODUCTS L.P.Inventors: Shivakumar Sundaram, Krishnamurthy Subramanian, Anoop Ghanwani, Pathangi Narasimhan Janardhanan, Mohnish Anumala, Raja Jayakumar

Patent number: 9553763Abstract: A system and method of automated Data Center Bridging (DCB) configuration of an access switch includes a control unit, a memory, and a port configured to couple the access switch to a peer device. The control unit is configured to operate the port according to a state machine including a DCB disabled state, a DCB downstream state, and a DCB upstream state. When the port is in the DCB disabled state, the control unit exchanges network traffic on the port without any DCB extensions. When the port is in the DCB upstream state, the control unit exchanges network traffic on the port using DCB extensions based on the DCB configuration and receives the DCB configuration from the peer device. When the port is in the DCB downstream state, the control unit exchanges network traffic on the port using the DCB extensions and transmits the DCB configuration to the peer device.Type: GrantFiled: April 27, 2016Date of Patent: January 24, 2017Assignee: DELL PRODUCTS L.P.Inventors: Senthil Kumar Ganesan, Raja Jayakumar, Ashok Daparthi, Aravind Babu Mahendrababu, Raja Subbiah

Patent number: 8654680Abstract: A stacked chassis comprising multiple physical switch/router chassis operates without any special stacking hardware or stacking channels. Instead, a stacking LAG is installed between front-end switch ports on the stacked chassis. The chassis controllers negotiate a master, which controls operation of all chassis in the stack. A stacked-chassis-wide port numbering scheme is used to distribute information to all line cards in the system. Each line card processes the information to distill physical-chassis significant information for operation of that chassis in the stack.Type: GrantFiled: July 20, 2010Date of Patent: February 18, 2014Assignee: Force10 Networks, Inc.Inventors: Krishnamurthy Subramanian, Raja Jayakumar, Pathangi Narasimhan Janardhanan

Patent number: 8599844Abstract: A packet network device includes a packet network processor memory system for storing information used to process and forward packets of information in and through the network device. The information is included in look-up tables whose entries can be mapped either horizontally or vertically into the memory system. In the event that the entries are mapped horizontally, a complete entry can be access at a single memory location and in the event that the entries are mapped vertically, the entries can be accessed at one or more memory locations.Type: GrantFiled: March 12, 2010Date of Patent: December 3, 2013Assignee: Force10 Networks, Inc.Inventors: Krishnamurthy Subramanian, Raja Jayakumar, Jason Lee
