  • 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.

  • Patent number: 9876561
    Abstract: A communication system, an apparatus and a method to route an Internet Protocol (IP) datagram with a standard internet routing protocol over a space link. The method including: routing according to the standard internet routing protocol including a current routing table including routing via the space link; receiving an Internet Protocol (IP) datagram including a destination; querying the routing stack to determine whether the destination is linked via the space link; and forwarding the IP Datagram to a space link address when IP datagram's destination is linked via the space link.

  • Patent number: 9800324
    Abstract: An apparatus and a system to preserve Internet Protocol (IP) addressing over a space link is disclosed. The apparatus includes: a network interface; a space link interface; a configuration table comprising Very Small Aperture Terminal (VSAT) network information and a satellite hub table, wherein the VSAT network information comprises subnet and range information for a network linked to the network interface; and a VSAT registration module. The VSAT registration module is configured to: select a satellite hub from the satellite hub table for communicating with using the space link interface, register the apparatus with the selected hub, and advertise the local-network information by communicating a route based on the local-network information to the selected hub, wherein the local-network information is independent of the hub selected from the satellite hub table.
