  • Patent number: 10917801
    Abstract: Various embodiments disclosed herein provide for a tower outage impact predictor that can determine the service impact on an end user during a cellular tower outage. Radio signal profiling divides an area into grids, and then constructs a radio signal profile for each grid based on user equipment (UE) measurement data for each grid. The number of UEs in each grid is then determined, and then the number of UEs that lose service for a simulated cellular tower outage is determined. Based on the impact analysis, a more resilient backhaul network can be implemented by determining backhaul rehoming changes that optimally home cellular towers to various backhaul network devices.

  • Patent number: 10904602
    Abstract: A system and method for bandwidth management by controlling the bit rate of a signal stream in real time according to available link bandwidth. Applications include multiple-channel video data streams over a limited-bandwidth link such as a Digital Subscriber Line. A video signal is transrated at the head end to multiple streams having different bit rates, by a multirating device which sends the multiple streams over a network, along with metadata containing information about the data structure and parameters of the streams. At the network access edge, a demultirating device uses the metadata to select the stream with the highest video quality whose bit rate does not exceed the available bandwidth of the end-user's access link. This scheme provides multiple unicast signals to different end-users in place of a single multicast signal, supports multiple high-definition channels over a limited bandwidth link, and is compatible with standard encryption methods.

  • Patent number: 10848419
    Abstract: Data transmission in a communication network is performed via a transmission path with which a master participant and at least one slave participant communicate. The master participant outputs messages on the data transmission path with which the slave participants exchange data on the fly. The messages output by the master participant contain datagrams which comprise a control data field and a payload field, where the control data field has a command field and an address field. In the case that at least one message has at least one datagram which is a write datagram in which the command field defines the data transmission procedure to be performed by a slave participant with the payload field as a write procedure, at least the control data field of a further datagram is arranged between the control data field of the write datagram and the payload field of the write datagram.

  • Patent number: 10826818
    Abstract: Switches within a telecommunications network exchange so-called available bandwidth messages, each of which advertises how much bandwidth remains unassigned on a respective link. The network is of a type in which circuits are provisioned with various predefined numbers of time slots (equivalent to bandwidth). The sending of an available bandwidth message for a given link is triggered by a change in the number of time slots available on that link if that change results in a change in the number of circuit bandwidths that can be accommodated by that link for a newly provisioned circuit.

  • Patent number: 10785148
    Abstract: A router operates in both a Segment Routing (SR) network portion and a Multiprotocol Label Switching (MPLS) network portion of a network that utilizes Open Shortest Path First (OSPF). The router receives an OSPF advertisement message originated by a mapping server that includes a sub-Type-length-value (sub-TLV) element that identifies a preferred type of path across the MPLS network portion for an identifiable set of traffic that is to be received by the router from the SR network portion. The router identifies, based at least in part upon the sub-TLV element, one path of a plurality of available paths across the MPLS network portion for the identifiable set of traffic, and configures its forwarding plane to utilize the identified one path accordingly for the identifiable set of traffic. The OSPF advertisement message can be an OSPF LSA, and can carry an Extended Prefix Range TLV including the sub-TLV element.
