Patent number: 8849647Abstract: Disclosed is a host bus adapter (HBA) that to receives an input/output (I/O) command from an operating system I/O driver. Firmware stored on the host bus adapter includes primary firmware and secondary firmware to process the I/O command. The HBA is to respond to the I/O command under the control of one of the primary firmware or secondary firmware. The selected one of said primary firmware and secondary firmware may be used to certify a hardware driver for either the current generation (primary firmware) or a future generation (secondary firmware).Type: GrantFiled: October 19, 2011Date of Patent: September 30, 2014Assignee: LSI CorporationInventors: Rajiv Bhatia, Ankit Sihare

Publication number: 20130163584Abstract: A system processes media, such as voice and video, in a scalable and secure manner. The system can process voice and video for a large quantity of users. For example, the system can enable large quantities of simultaneous phone conversations over an IP network. The IP network can carry voice, video, and other data concurrently. The system identifies which packets carry voice data, which packets carry video, and which packets carry other kinds of data. The system scales both with the quantity of users and in terms of network topology. Multiple digital signal processors (DSPs) can be controlled by and connected to a switching device via an Ethernet network. One or more DSPs connected to the switching device interact with the switching device as separate IP devices, in that each such DSP may have its own separate IP address to which IP packets may be addressed.Type: ApplicationFiled: June 29, 2012Publication date: June 27, 2013Applicant: Network Equipment Technologies, Inc.Inventors: Prakash Jayaraman, Rajiv Bhatia

Publication number: 20130132766Abstract: Disclosed is a storage enclosure having a plurality of servers each having a storage controller. A second storage controller that is not part of any of the plurality of servers is embedded in the storage enclosure. The second storage controller is configured to process I/O commands directed to one of the server's storage controllers when a storage controller fails. In this manner, the storage controllers that are part of the servers may be fully utilized and still have a failover capability to the enclosure storage controller instead of another server storage controller that may also be fully utilized.Type: ApplicationFiled: November 23, 2011Publication date: May 23, 2013Inventors: Rajiv Bhatia, Ankit Sihare

Publication number: 20130124774Abstract: Disclosed is a system for installing operating system files on logical unit numbers (LUNs). At a SAS switch, a command to initiate an operating system installation on a LUN)associated with a SAS host bus adapter (HBA) connected to said SAS switch is received. In response to the command, a PXE session with a PXE server is established. Using the PXE session, operating system files are transferred to the LUN via the SAS switch thereby installing the operating system on said LUN.Type: ApplicationFiled: November 16, 2011Publication date: May 16, 2013Inventors: Ankit Sihare, Rajiv Bhatia

Patent number: 6829239Abstract: A LAN modem permits unambiguous routing for multiple workstations located on a LAN to each gain access through the LAN modem to any one of a number of different remote servers located on a number of different remote networks using a combination of public port number and public address of the workstation. There are instances where sessions are changed between the same workstation/server. This changing of sessions changes the public port numbers associated with each session, which destroys the above unambiguous routing, since the combination of a public destination IP address and a private destination port number is no longer the same unique value contained in an address translation table of the LAN modem. A four step hierarchical procedure is provided in which the LAN modem determines which workstation the packet is to be routed based upon value of fields stored in the network address translation (NAT) table or value of fields stored in a static table.Type: GrantFiled: May 9, 2003Date of Patent: December 7, 2004Assignee: 3Com CorporationInventors: Rajiv Bhatia, Daniel M Brennan, C.

The LAN modem includes an internal web server for autonomously constructing and downloading a web page, through dynamic selective insertion of predefined event-specific web page components into a web page template, to the workstation. The resulting page informs a user stationed at the workstation of a failure condition or other operational event that then occurred at the LAN modem. The specific page components inserted into the template are selected based on the particular failure condition or other operational event which occurred.Type: GrantFiled: September 26, 1997Date of Patent: July 25, 2000Assignee: 3Com CorporationInventor: Rajiv Bhatia

Through use of a multi-tiered routing hierarchy including both destination- and source-based routing, the LAN modem accommodates several modalities of network communication not heretofore possible in a conventional router. Specifically, several different workstations can simultaneously communicate through the LAN modem with a common remote network and share a single user account at a corresponding network service provider.Type: GrantFiled: September 26, 1997Date of Patent: February 22, 2000Assignee: 3Com CorporationInventors: Rajiv Bhatia, C.

Patent number: 5654961Abstract: In a networked videoconferencing system, a receiver with a number of receiving stations receives calls from a number of different calling stations. To get appropriate bandwidth, two calls are connected at the same time from the calling station to one of the receiving stations. The receiver includes an access switch that uses information from the calling station to pair calls together so that two calls from one calling station are routed to the same receiving station, regardless of the order in which the calls are received by the access switch. The access switch can use one or a combination of routing methods including storing all pairs of incoming numbers in a table and/or by using comparisons of similar numbers.Type: GrantFiled: May 22, 1995Date of Patent: August 5, 1997Assignee: Madge Networks (New Jersey) Inc.Inventors: Kenneth Araujo, Rajiv Bhatia, Michael Harmon, Roderick Randall, Siuling Zhang

Patent number: 4672604Abstract: A multi-stage time division switch interconnects a plurality of processors that individually communicate over one or more channels at various signalling rates. Any processor may initiate a call and request that a connection be set by the switch. The switch assigns one or more time slots to the call and gathers or distributes data over the interconnecting channels through the utilization of polling techniques, thereby creating a virtual circuit through the combination of a time division switch and a polled communication line.Type: GrantFiled: July 8, 1985Date of Patent: June 9, 1987Assignees: American Telephone and Telegraph Company, Bell Telephone Laboratories, Incorporated, AT&T Information Systems Inc.Inventors: Rajiv Bhatia, Joseph G. Kneuer

Patent number: 4633461Abstract: A multi-stage time division switch interconnects processors communicating over one or more channels on time division lines. One of the processors is designated as a common processor to provide the switching "mapping" information for the various stages of the switch sending the switching information to the memory and logic of each switched stage over dedicated channels which include channels on the time division line emanating from the common processor and time division channels which pass through several switches until the memory of the applicable switch is accessed.Type: GrantFiled: July 8, 1985Date of Patent: December 30, 1986Assignees: AT&T Information Systems Inc., Bell Telephone Laboratories, IncorporatedInventors: Randall G.
