20190394055 | BIT INDEX EXPLICIT REPLICATION (BIER) PENULTIMATE HOP POPPING - A network device may receive, from a first neighbor network device, information indicating that the network device is to remove a bit indexed explicit replication (BIER) header from a multicast packet prior to transmitting the multicast packet to the first neighbor network device. The network device may receive the multicast packet from a second neighbor network device, where the multicast packet includes the BIER header and is to be transmitted to the first neighbor network device, and where the network device, the first neighbor network device, and the second neighbor network device are included in a same BIER domain. The network device may remove the BIER header from the multicast packet, and may transmit the multicast packet to the first neighbor network device after removing the BIER header from the multicast packet. | 2019-12-26 |
20190394056 | MULTICAST SERVICE PROCESSING METHOD AND ACCESS DEVICE - A multicast service processing method and an access device. In the method, an access device receives an on-demand request; the access device separately sends the on-demand request to a multicast source device through a first uplink port of the access device and a second uplink port of the access device, so that the multicast source device sends a first multicast packet and a second multicast packet based on the on-demand request; the access device receives the first multicast packet through the first uplink port of the access device, and receives the second multicast packet through the second uplink port of the access device; the access device obtains a multicast data stream based on attribute information of the first multicast packet and attribute information of the second multicast packet; and the access device sends the obtained multicast data stream to the program terminal. | 2019-12-26 |

20190394058 | SYSTEM AND METHOD FOR RECORDING AND REVIEWING MIXED-MEDIA COMMUNICATIONS - A method and system for transmitting, reviewing, and analyzing mixed-media communications are disclosed. The system includes one or more databases to store information in multiple formats. The information in multiple formats can be reviewed using a single application on a device for easy review and analysis of the mixed media communications. | 2019-12-26 |
20190394059 | BIT INDEX EXPLICIT REPLICATION (BIER) PENULTIMATE HOP POPPING - A network device may receive, from a first neighbor network device, information indicating that the network device is to remove a bit indexed explicit replication (BIER) header and a BIER label from a multicast packet prior to transmitting the multicast packet to the first neighbor network device. The network device may receive the multicast packet from a second neighbor network device, where the multicast packet includes the BIER header and the BIER label and is to be transmitted to the first neighbor network device, and where the network device, the first neighbor network device, and the second neighbor network device are included in a same BIER domain. The network device may remove the BIER header and the BIER label from the multicast packet, and may transmit the multicast packet to the first neighbor network device after removing the BIER header and the BIER label from the multicast packet. | 2019-12-26 |
20190394060 | POWER LINE COMMUNICATIONS NETWORK SYSTEM FOR A SPA - A system for power line communications between an in-home wireless network and a pool or spa. The system may include a spa network interface in electrical wired connection to an in-home network interface. The spa power line communication module may be hard wired to a spa control unit, and power to the spa may be provided by one or more of a first 120V conductor having a first phase of power, a second 120V conductor having a second phase of power, a ground conductor, and a neutral conductor. The system may optimize the connection between the in-home powerline communications module connected to one phase of power via a home receptacle, and the spa powerline communications module by testing the connection over each conductor and selecting the conductor with the best throughput. | 2019-12-26 |
20190394061 | VIRTUAL NETWORK ENDPOINTS FOR INTERNET OF THINGS (IOT) DEVICES - Systems and methods herein represent an IoT device as an endpoint of private cloud. A virtualization service receives an IoT identifier for an IoT device and a network address for a virtual endpoint for the IoT device. The virtual endpoint for the IoT device is included in a host cloud platform. The virtualization service maps the IoT identifier to the network address in a distributed data structure for the service provider network and provides instructions, for an edge node for the service provider network, to provide network-layer access controls based on the mapping. The edge node for the service provider network receives an access request from the IoT device, applies a network-layer access control for the IoT device based on the instructions, receive IoT data from the IoT device when the edge node permits access by the IoT device, and forwards the IoT data to the virtual endpoint. | 2019-12-26 |
20190394062 | INFORMATION NOTIFICATION METHOD, APPARATUS, AND SYSTEM - The present application discloses an information notification method and apparatus. The method is used for a first entity, and includes: determining a first resource feature; determining whether a structure of resources satisfies the first resource feature; and transmitting a notification message to a second entity if the structure of the resources satisfies the first resource feature. | 2019-12-26 |
20190394063 | ELECTRONIC DEVICE AND METHOD FOR PROVIDING NOTIFICATION SERVICE THEREFOR - An electronic device is disclosed. The electronic device comprises: a communication unit for performing communication with at least one external electronic device; and a processor for receiving, from the external electronic device, interest information of a user in the external electronic device and system information in the external electronic device, comparing the received interest information and system information with notification service information of the electronic device, and determining whether the user registers a notification service. | 2019-12-26 |
