Patent number: 10659284Abstract: A distributed device architecture includes a master device and one or more member devices. A simple network management protocol (SNMP) agent of a master device receives an SNMP request from a managing device. Where the SNMP request pertains to a given member device, and where the SNMP request requires involvement of the given member device to fulfill the SNMP request, the master device generates a non-SNMP request corresponding to the SNMP request and transmits the non-SNMP request to the given member device. A non-SNMP agent of the given member device processes the non-SNMP request and transmits processing results back to the master device. The master device generates an SNMP response corresponding to the processing results, and the SNMP agent of the master device transmits the SNMP response back to the managing device.Type: GrantFiled: July 25, 2014Date of Patent: May 19, 2020Assignee: International Business Machines CorporationInventors: Keshav G.

Patent number: 9804907Abstract: A distributed system includes first-tier entities, and a master entity in communication with each first-tier entity. The master entity provides a single access point through which an administrator can submit commands to manage all entities. The master entity maintains a table of virtual slots. Each virtual slot points to one of the first-tier entities, and each first-tier entity is pointed to by at least one virtual slot. The processor runs an RPC (remote procedure call) client to submit RPC requests to the first-tier entities, and determines a destination first-tier entity for a given RPC request in response to which virtual slot the administrator submits a command. The distributed system can include second-tier entities, each indirectly communicating with the master entity through a first-tier entity. The table has a virtual slot for each second-tier entity, which points to the first-tier entity acting as proxy for the second-tier entity.Type: GrantFiled: November 6, 2013Date of Patent: October 31, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Sushma Anantharam, Nirapada Ghosh, Dayavanti Gopal Kamath, Keshav Govind Kamble, Dar-Ren Leu, Chandarani J.

Patent number: 9166869Abstract: Management of a network may be provided by moving management functions from each switch in a network cluster into a locally controlled server. The management functions may be organized into an Ethernet distributed fabric switching protocol (E-DFP) based management plane. Control functions of each switch may also be organized into a control plane. The management plane and control plane of the network may be moved from each switch and integrated into the server. Efficiency in network switching may be provided by releasing the switches of their management and control responsibilities and centralizing these responsibilities to the server. In some embodiments, the server may be outside the cluster.Type: GrantFiled: January 14, 2013Date of Patent: October 20, 2015Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Keshav G.

Patent number: 9088477Abstract: A distributed fabric system comprises a plurality of independent network elements interconnected by inter-switch links and assigned to a same group. Each network element includes a switching chip, a processor, and memory storing program code that is executed by the processor. The program code of each network element includes a device configuration (DC) stacking module and a switch discovery protocol (SDP) module. The SDP module of each network element, when executed, discovers each other network element in the group and elects one of the network elements as a master network element. The SDP module of the master network element, when executed, sends messages to the DC-stacking module of the master network element. Each sent message identifies one of the network elements in the group. The DC stacking module of the master network element, when executed, maintains a record of all network elements that are currently members in the group.Type: GrantFiled: February 2, 2012Date of Patent: July 21, 2015Assignee: International Business Machines CorporationInventors: Sushma Anantharam, Nirapada Ghosh, Keshav Govind Kamble, Dar-Ren Leu, Chandarani J.

Patent number: 9059937Abstract: A switch includes network ports and a network processor with a fabric interface that provides SerDes (Serializer/Deserializer) channels. The network processor divides each packet received over the network ports into cells and distributes the cells across the SerDes channels. Fabric ports of the switch communicate with the fabric interface to transmit cells to and receive cells from the fabric interface. The switch is selectively configurable as a standalone switch by connecting each fabric port of the switch to another of the fabric ports of the switch, as a member of a switch stack by connecting each fabric port of the switch to a different other switch through one fabric port of that other switch, or as a member of a distributed fabric system by connecting each fabric port of the switch to a different scaled-out fabric coupler (SFC) chassis by an SFC fabric port of that SFC chassis.Type: GrantFiled: April 4, 2014Date of Patent: June 16, 2015Assignee: International Business Machines CorporationInventors: Sushma Anantharam, Alexander Philip Campbell, Keshav Govind Kamble, Dar-Ren Leu, Vijoy A.
