Patent number: 7778244Abstract: A system for management of storage devices includes compatibility with either or both of COM/RS232 port and USB port connectivity using, for example, Fibre Channel (FC) signal transmission. A USB to serial RS232 bridge device allows a storage processor (SP) to communicate with an COM/RS232 port of a universal asynchronous receiver/transmitter (UART) coupled to downstream disk array enclosures (DAEs) to provide DAE management information without the need to modify the connection of the switch to the DAEs, which may include FC interconnects. The output from an COM/RS232 port on an SP interface and the RS232 output on the USB to Serial bridge device may be muxed at the UART, and the output signal therefrom diplexed with a high frequency differential signal and transmitted to one or more of the downstream DAEs as an FC diplexed signal.Type: GrantFiled: September 27, 2007Date of Patent: August 17, 2010Assignee: EMC CorporationInventors: Rizwan Sheikh, Stephen Edward Strickland, Phillip Leef

Patent number: 7773588Abstract: A multimedia communication system and method are described where a communication controller receives a multimedia data stream from a communication device in a first protocol. The controller detects a type of the first protocol, such as text-based protocol or a binary protocol and then converts the first protocol into an intermediate protocol. The multimedia data stream in this intermediate protocol is then transmitted to a second communication controller connected to the destination communication device. The multimedia data stream is then converted at the second communication controller from the intermediate protocol into a second protocol which is then used to transmit the multimedia data stream to the destination communication device.Type: GrantFiled: April 13, 2006Date of Patent: August 10, 2010Assignee: directPacket Research, Inc.Inventors: Christopher S. Signaoff, Tom W. Opsahl, Edward M. Riley, III, Justin S. Signaoff

Patent number: 7769042Abstract: Communicating data packets between a client device and a host system generally includes using a protocol server module, located on the client device, that terminates a communication session that uses a first protocol and that is intended to enable communications between a source and a destination, in which the source is one of a client device operating system protocol stack and the host system and the destination is one of the client device operating system protocol stack and the host system but differs from the source. The protocol server module translates data packets from the source between the first protocol and a second protocol that is different from the first protocol and transports the data packets having the second protocol to the destination. A controller module generally also is included on the client device. The protocol server module may include a PPP server module located on the client device.Type: GrantFiled: September 18, 2006Date of Patent: August 3, 2010Assignee: AOL Inc.Inventor: Patrick A. Meenan

Patent number: 7760623Abstract: A computer network processes data packets in the event of a network link failure. The network includes a plurality of routers that deliver data packets to the network via a plurality of links. At least one router includes a protection cycle manager. The protection cycle manager has a protection cycle packet identifier and a protection cycle packet processor. The protection cycle packet identifier identifies, as protection cycle packets, data packets having a specific protection cycle format. The protection cycle packet processor processes protection cycle packets to determine whether the packet destination corresponds to the routing node, and if the packet destination corresponds to the routing node, the protection cycle packet is treated by the routing node as a data packet received from the packet source via the failed link. Otherwise, if the packet destination does not correspond to the routing node, the protection cycle packet is sent to a protection cycle node for the routing node.Type: GrantFiled: December 22, 2008Date of Patent: July 20, 2010Assignee: Nortel Networks LimitedInventors: Loa Andersson, Kent Felske, Guo-Qiang Wang

Patent number: 7760706Abstract: Methods and systems for load sharing signaling messages at the MTP level are disclosed. When a signaling message is received, it is determined whether the signaling message includes a routing indication indicating route-on-point-code-subsystem-number. If the routing indicator indicates route-on-point-code-subsystem-number, it is determined whether the signaling message belongs to an MTP level 3 load sharing group. If the signaling message belongs to an MTP level 3 load sharing group, the signaling message may be routed to any of the point codes in the MTP level 3 load sharing group. Routing the signaling message to a point code in the MTP level 3 load sharing group may include replacing the destination point code in the signaling message with the destination point code of the node to which the signaling message is to be routed. Once the point code has been replaced, the signaling message is routed to the destination associated with the point code.Type: GrantFiled: November 19, 2004Date of Patent: July 20, 2010Assignee: TekelecInventors: Robert J.

Patent number: 7751434Abstract: A unified architecture for a multipoint VC session and interactive broadcasting system is provided that includes a server, one or more video accessing points, reflectors and client machines. The server sets up the video communication sessions (VC sessions), each of which is hosted by one video accessing point. The server downloads the A/V client software to client machines. Reflectors direct audio/visual signals to client machines. The reflectors are coupled to the video accessing point and receive a control signal from the video accessing point in order to direct the A/V signals from the client machines participating in the VC session. The client machines process all of the A/V signals. This system for distributing the VC session tasks across these components reduces any bottleneck effect from using a single, central control point to direct the VC session and route the A/V signals.Type: GrantFiled: December 19, 2006Date of Patent: July 6, 2010Assignee: Imajet Communications, Inc.Inventor: Leonid Kasperovich
