Cisco Technology Assigned Five Patents

Unlocking computing resources for decomposable data centers
Cisco Technology, Inc., San Jose, CA, has been assigned a patent (11601377) developed by Kar, Chakradhar, Borikar, Sagar, San Jose, CA, Sivakolundu, Ramesh, Saratoga, CA, Banerjee, Ayan, Fremont, CA, and Thakar, Anant, Los Altos, CA, for “unlocking computing resources for decomposable data centers.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Techniques for sending Compute Express Link (CXL) packets over Ethernet (CXL-E) in a composable data center that may include disaggregated, composable servers. The techniques may include receiving, from a first server device, a request to bind the first server device with a multiple logical device (MLD) appliance. Based at least in part on the request, a first CXL-E connection may be established for the first server device to export a computing resource to the MLD appliance. The techniques may also include receiving, from the MLD appliance, an indication that the computing resource is available, and receiving, from a second server device, a second request for the computing resource. Based at least in part on the second request, a second CXL-E connection may be established for the second server device to consume or otherwise utilize the computing resource of the first server device via the MLD appliance.”

The patent application was filed on 2022-05-23 (17/751181).

Distributed erasure encoding
Cisco Technology, Inc., San Jose, CA, has been assigned a patent (11599412) developed by Agarwala, Sandip, Cupertino, CA, and Gaonkar, Shravan, Gainesville, FL, for “method and apparatus for distributed erasure encoding.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Systems, methods, and computer-readable media are provided for utilizing distributed erasure encoding in a redundant array of independent disks (RAID) system. An example method can include generating a plurality of virtual redundant array of independent disk (vRAID) stripes, each of the plurality of vRAID stripes including a segment having a plurality of data, each of the plurality of data including metadata, the metadata including a checksum of a corresponding data of the plurality of data, distributing the segment of each of the plurality of vRAID stripes over a plurality of virtual nodes, mapping at least one of logical files, volumes, or objects to the plurality of data chunks and the at least one parity chunk of the plurality of vRAID stripes to avoid write-hole issues, and verifying data integrity of the corresponding data of the plurality of data using the checksum of the corresponding data.”

The patent application was filed on 2021-09-15 (17/475522).

Accelerating data replication using multicast and NVMs enabled nodes
Cisco Technology, Inc., San Jose, CA, has been assigned a patent (11595474) developed by Dutta, Debojyoti, Santa Clara, CA, Saha, Amit Kumar, Bangalore, India, George, Johnu, San Jose, CA, Pydipaty, Ramdoot Kumar, Bangalore, India, and Tarre, Marc Solanas, San Jose, CA, for an “accelerating data replication using multicast and non-volatile memory enabled nodes.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method for accelerating data operations across a plurality of nodes of one or more clusters of a distributed computing environment. Rack awareness information characterizing the plurality of nodes is retrieved and a non-volatile memory (NVM) capability of each node is determined. A write operation is received at a management node of the plurality of nodes and one or more of the rack awareness information and the NVM capability of the plurality of nodes are analyzed to select one or more nodes to receive at least a portion of the write operation, wherein at least one of the selected nodes has an NVM capability. A multicast group for the write operation is then generated wherein the selected nodes are subscribers of the multicast group, and the multicast group is used to perform hardware accelerated read or write operations at one or more of the selected nodes.”

The patent application was filed on 2017-12-28 (15/856716).

Route exchange in multi-tenant clustered controllers
Cisco Technology, Inc., San Jose, CA, has been assigned a patent (11588752) developed by Tangirala, Srilatha, San Jose, CA, Raju, Nithin Bangalore, Santa Clara, CA, Raval, Ananya, Ottawa, Canada, Radhakrishnan, Prabahar, Dublin, CA, Agarwal, Vivek, Campbell, CA, and Sundararajan, Balaji, Fremont, CA, for a “route exchange in multi-tenant clustered controllers.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Route exchange in a plurality of network controller appliances on a per-tenant basis is disclosed. In one aspect, a method includes receiving, from a network management system and at a first network controller appliance, a designation of at least two tenants to be hosted on the first network controller appliance, the first network controller appliance being one of a plurality of network controller appliances in a SD-WAN, sending, from the first network controller appliance to other network controller appliances of the plurality of network controller appliances, a tenant list query message to obtain a corresponding tenant list of each of the other network controller appliances, and receiving a corresponding response from each of the other network controller appliances indicating the corresponding tenant list of each of the other network controller appliances, the corresponding response being used to update the tenant list on the first network controller appliance.”

The patent application was filed on 2021-07-29 (17/389003).

Techniques for implementing IPV6-based distributed storage space
Cisco Technology, Inc., San Jose, CA, has been assigned a patent (11588783) developed by Mason, Seth, San Jose, CA, Townsley, William Mark, Paris, France, Surcouf, Andre, Saint Leu la Foret, France, Gruszka, Thierry, Paris, France, and Hawari, Mohammed, Guebwiller, France, for “techniques for implementing IPV6-based distributed storage space.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method is provided in one example embodiment and includes, for each of a plurality of individual storage units collectively comprising a virtual storage unit, mapping an internal address of the storage unit to a unique IP address, wherein each of the storage units comprises a block of storage on one of a plurality of physical storage devices and wherein the IP address includes a virtual storage unit number identifying the virtual storage unit, receiving from a client a request to perform an operation on at least one of the data storage units, wherein the request identifies the internal address of the at least one of the data storage units, translating the internal address of the at least one of the data storage unit to the unique IP address of the at least one of the data storage units, and performing the requested operation on the at least one of the data storage units.”

The patent application was filed on 2016-03-20 (15/075163).
