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: 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: 9077651Abstract: A distributed fabric system has distributed line card (DLC) chassis and scaled-out fabric coupler (SFC) chassis. Each DLC includes a network processor and fabric ports. Each network processor of each DLC includes a fabric interface in communication with the fabric ports of that DLC. Each SFC includes at least one fabric element and SFC fabric ports. A fabric communication link connects each SFC fabric port to one DLC fabric port. Each fabric communication link includes cell-carrying lanes. Each fabric element of each SFC detects connectivity between each SFC fabric port of that SFC and one DLC fabric port over a fabric communication link. Each SFC includes program code that reads connectivity matrix from fabric element chips and sends connection information corresponding to the detected connectivity from that SFC to a central agent. A network element includes the central agent, which, when executed, constructs a topology of the distributed fabric system from the connection information sent from each SFC.Type: GrantFiled: March 7, 2012Date of Patent: July 7, 2015Assignee: International Business Machines CorporationInventors: Sushma Anantharam, Nirapada Ghosh, Dayavanti Gopal Kamath, Keshav Govind Kamble, Dar-Ren Leu, Chandarani J.

Patent number: 8767722Abstract: A switching network includes an upper tier having a master switch and a lower tier including a plurality of lower tier entities. The master switch, which has a plurality of ports each coupled to a respective lower tier entity, implements on each of the ports a plurality of virtual ports each corresponding to a respective one of a plurality of remote physical interfaces (RPIs) at the lower tier entity coupled to that port. Data traffic communicated between the master switch and RPIs is queued within virtual ports that correspond to the RPIs with which the data traffic is communicated. The master switch applies data handling to the data traffic in accordance with a control policy based at least upon the virtual port in which the data traffic is queued, such that the master switch applies different policies to data traffic queued to two virtual ports on the same port of the master switch.Type: GrantFiled: August 27, 2012Date of Patent: July 1, 2014Assignee: International Business Machines CorporationInventors: Keshav Kamble, Amitabha Biswas, Dar-Ren Leu, Chandarani J.
