Other embodiments are disclosed. | 2021-12-16 |
20210392006 | POWER-OVER-ETHERNET (POE) BREAKOUT MODULE - Presented herein are embodiments of a power-over-Ethernet (PoE) breakout system that may be used to breakout a PoE port from a PoE information handling system into a number of breakout ports. In one or more embodiments, a PoE breakout system comprises: a PoE port for connecting to a PoE information handling system, such as a PoE switch; a plurality of breakout ports for connecting to powered devices, wherein each breakout port is configured to supply power to a powered device; and a power management module electrically coupled to the PoE port and configured to supply power to each breakout port according to a configuration that sets a power level for that breakout port. In one or more embodiments. the PoE breakout system comprises a data communications module that switches data traffic to a correct PoE breakout port according to its intended powered device. | 2021-12-16 |
20210392007 | OVER THE TOP NETWORK TRAFFIC CLASSIFICATION - A system and method is disclosed to transform Over-The-Top (OTT) call log data collected by telecommunications network operators into a peer-to-peer log in order to determine more accurate information. In this method the IP addresses in the call log records are compared to a list of known mediator server IP addresses and the records in the log that contain mediator server IP addresses are removed from the log to create a peer-to-peer log containing only those records that contain peer IP addresses. The data in the peer-to-peer log can then be categorized with confidence to determine network performance information as well as, for example, the percentage of traffic to a particular country. Conclusions may then be inferred regarding the removed data records based upon the data found in the peer-to-peer log. | 2021-12-16 |
20210392008 | REAL-TIME VIRTUAL MEETING TOOL THAT COMBINES VIDEO CHAT WITH USER ACTIVITIES - A real-time virtual conference system is disclosed that combines video chat with structured activities. The invention can deliver various forms of web content, on command, with integrated video. User actions are monitored, measured, and reported in real-time, so that the host understands the progress of the users. The system employs an activity scheduler which allows a Host to set up a schedule of activities during a setup phase which can run sequentially or change at predetermined times during an Operation Phase. This provides a structure to the session. The system employs standard browser software for directly interacting with websites, or standard applications. The Host has control of the browser settings, layout state and content state of the users' devices to synchronize and control several user devices during a remote session and provide desired output in a desired form to each user device. | 2021-12-16 |
20210392009 | MULTICAST SOURCE DISCOVERY PROTOCOL (MSDP) LOOP AVOIDANCE - The disclosure describes techniques for enhancements to the Multicast Source Discovery Protocol (MSDP) to reduce Source Active (SA) message loops in one or more multicast domains having overlapping MSDP mesh groups. In some examples, a method includes receiving, by a first MSDP speaker, from a second MSDP speaker, a SA message. The method also includes, when the second MSDP speaker is in a mesh group with the first MSDP speaker, determining whether the first MSDP speaker includes an active SA state corresponding to the SA message. Additionally, the method includes, when the first MSDP speaker does not include the active SA state corresponding to the SA message, accepting the SA message and forwarding the SA message to a third MSDP speaker that is not in the mesh group with the first MSDP speaker and the second MSDP speaker. | 2021-12-16 |
20210392010 | SMART ADAPTATION OF THE FUNCTIONALITIES OF A REMOTE CONTROL IN A LOCAL AREA NETWORK - The invention relates to the adaptation of the functionalities of a remote control in a local area network. More specifically, it relates to the definition of commands to be sent upon an input of a user, depending either of the commands that can be sent in a RF network joined by the remote control, or of the commands that can be received by a device that the remote control is bound to in a RF network. | 2021-12-16 |
20210392011 | USER STATION FOR A SERIAL BUS SYSTEM AND METHOD FOR COMMUNICATION IN A SERIAL BUS SYSTEM - A user station for a serial bus system and a method for communication in a serial bus system. The user station includes a communication control unit, and a transceiver unit for transmitting a transmit signal for a message which is exchanged between user stations of the bus system. The bit time of a signal transmitted in the first communication phase on the bus differs from a bit time of a signal transmitted in the second communication phase. The communication control unit generates the transmit signal according to a frame, in which in addition to a field which indicates the priority of the message, a field for a data type is provided, and the communication control unit being designed to write a value in the field for the data type which indicates which type of information is located in a data field of the frame. | 2021-12-16 |
20210392012 | CONTROL UNIT ARCHITECTURE FOR VEHICLES - A control unit architecture and a method in which a communication connection takes place between at least two control units, in particular in a vehicle. The method includes receiving the data packet by the first interface controller; determining, by a data analyzer, a transmission strategy for the data packet, the transmission strategy including at least one of the following actions: rejecting the data packet, and/or sending the data packet to at least one of the second interface controllers, and/or sending the data packet to at least one of the buffer stores, and/or fragmenting the data packet and sending it to at least one of the buffer stores, and/or sending the content of the at least one buffer store to at least one of the second interface controllers; implementing the transmission strategy for the data packet. | 2021-12-16 |
