Patents by Inventor Chandrasekhar Sangireddi

Chandrasekhar Sangireddi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11664888
    Abstract: Systems and methods are provided to achieve dynamic bandwidth allocation among terminal groups (TGs) with proportional fairness in terms of both throughput and spectrum usage across a network. Quality of service (QoS) metrics for such TGs can be satisfied in terms of maximum throughput and spectrum utilization, while also satisfying QoS metrics such as latency, throughput, and prioritized traffic services for individual terminals within the TGs. A centralized bandwidth manager can be utilized to manage such dynamic bandwidth allocation across multiple Code Rate Organizers (CROs), including environments in which the multiple CROs manage communications across multiple IPGWs for multiple terminal groups. Because, in such environments, a given conventional CRO cannot effectively manage allocations across the entire network, the centralized bandwidth management functionality can be introduced to assess the flows for multiple TGs across multiple CROs and to make bandwidth allocations accordingly.

  • Patent number: 11387895
    Abstract: A communication method includes receiving, by a first node of a satellite communications network, a stream of terrestrial data packets that are encapsulated in accordance with a predetermined protocol, de-encapsulating, by the first node, the terrestrial data packets to extract user plane context and QoS parameters for a user session in accordance with the predetermined protocol, encapsulating, by the first node, the user plane context within satellite data packets, and transmitting, by the first node, the satellite data packets to a second node of the satellite communications network via a satellite communications link between the first node and the second node by scheduling the satellite data packets using the QoS parameters in accordance with the predetermined protocol.

  • Patent number: 10700771
    Abstract: Systems and methods provide bandwidth management on the inroute of a satellite network. Inroute group managers (IGMs) monitor bandwidth usage in each terminal group (TG) under each of the IGMs, and report this bandwidth usage to a bandwidth manager. Upon receipt of the reported bandwidth usage from each of the IGMs, the bandwidth manager compares the bandwidth usage and minimum/maximum throughput rates associated with each TG. The bandwidth manager calculates scaling factors that it transmits to each of the IGMs to allow the IGMs to allocate bandwidth accordingly.
