Publication number: 20220269330Abstract: A system includes multiple processors and a power controller. Each processor includes a throttling engine. The power controller is to, in response to a determination that a first power consumption level exceeds a first threshold, assert a critical signal to each throttling engine of the plurality of processors. Further, for each processor, the throttling engine of the processor is to perform a sequence of multiple throttling states while the critical signal is asserted by the power controller, where the sequence of multiple throttling states is performed according to a state machine of the throttling engine. Other embodiments are described and claimed.Type: ApplicationFiled: May 11, 2022Publication date: August 25, 2022Inventors: AHMED ABOU-ALFOTOUH, PHANI KUMAR KANDULA, LINDA L. HURD, ERIC C.

Patent number: 9608898Abstract: A multicast path trace capability is provided for tracing a multicast path from a root node to a leaf node where the trace originates at the leaf node. The leaf node sends a multicast trace request to the root node. The root node receives the multicast trace request and initiates a path trace request for collecting path information associated with the multicast path. The root node receives at least one path trace response, in response to the path trace request, which includes path information associated with the multicast path. The root node sends a multicast trace response, including the collected path information, to the leaf node. The leaf node receives the multicast trace response including the path information. The leaf node derives end-to-end path information for the multicast path using the path information received in the multicast trace response. The multicast path trace capability may be used for tracing an MPLS multicast path (e.g.Type: GrantFiled: August 5, 2010Date of Patent: March 28, 2017Assignee: Alcatel LucentInventors: Srikrishnan Venkataraman, Kanwar Singh, Pradeep G.

Patent number: 8982691Abstract: A method for providing a Backup Label Switched Path for a specified Bypass Label Switch Path is disclosed. The method for providing a Backup Label Switched Path for a specified Bypass Label Switch Path includes establishing a Bypass LSP having an end-to-end path; obtaining the nodes traversed by the end-to-end path; generating a request to a path calculator which using the nodes provided on the end-to-end path calculates a path disjoint to those nodes; and signaling the calculated disjoint path as a Backup LSP for the Bypass LSP. The method for providing a Backup Label Switched Path for a specified Bypass Label Switch Path provides protection advantages over systems known in the art by providing capability for handling double failure scenarios.Type: GrantFiled: September 28, 2012Date of Patent: March 17, 2015Assignee: Alcatel LucentInventors: Pradeep Jain, Kanwar Singh, Srikrishnan Venkataraman

Patent number: 8879384Abstract: One example embodiment of the method includes receiving first control packets, by a first node, from a source node. The first control packets indicate the status of the source node. Whether the source node is operational and if a connection path between the first node and the source node is operational is determined based on the received first control packets. The method further includes sending a second control packet to a downstream node if the source node is non-operational, or the connection is non-operational. The second control packet includes at least one value indicating the source node is unreliable.Type: GrantFiled: January 8, 2010Date of Patent: November 4, 2014Assignee: Alcatel LucentInventors: Srikrishnan VenkataRaman, Sandeep Bishnoi, Pradeep G.
