Cisco Assigned Two Patents

Multi-fabric SAN based data migration
Cisco Technology, Inc., San Jose, CA, has been assigned a patent (9,256,572) developed by Barooah, Manas, Cupertino, CA, and Chari, Rahul, Kodihali, India, for a “multi-fabric SAN based data migration.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”In one embodiment, a network device in a network obtains information identifying first storage and second storage. The network device notifies one or more other network devices in the network that traffic that is received by the other network devices is to be routed to the network device. The network device performs data migration from the first storage to the second storage. When the data migration from the first storage to the second storage is completed, the network device notifies the other network devices in the network that traffic that is received by the other network devices is no longer to be routed to the network device.“

The patent application was filed on November 28, 2014 (14/556,066).

Rule-based virtual address translation for accessing data
Cisco Technology, Inc., San Jose, CA, has been assigned a patent (9,256,548) developed by Steiss, Donald Edward, Richardson, TX, Martinez, Jr., Marvin Wayne, Plano, TX, Bettink, John H. W., San Jose, CA, Carney, John C., Lexington, MA, and Hervin, Mark Warden, Plano, TX, for a “rule-based virtual address translation for accessing data.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”In one embodiment, rule-based virtual address translation is performed for accessing data, (e.g., reading and/or writing data) typically stored in different manners and/or locations among one or more memories, such as, but not limited to, in packet switching devices. A virtual address is matched against a set of predetermined rules to identify one or more storing description parameters. These storing description parameters determine in which particular memory unit(s) and/or how the data is stored. Thus, different portions of a data structure, e.g., table) can be stored in different memories and/or using different storage techniques. The virtual address is converted to a lookup address based on the identified storing description parameter(s). One or more read or write operations in one or more particular memory units is performed based on the lookup address said converted from the virtual address.“

The patent application was filed on November 29, 2012 (13/688,520).
