  • Anycast routing techniques in a network
    Patent number: 10771540
    Abstract: Aspects of the present disclosure involve systems, methods, computer program products, and the like, for managing the distribution of content and/or communications from a telecommunications or computer network to an end user of the network. In general, the system receives a request for content from a user of the network and analyzes the request to determine an estimated geographic region and/or an access network associated with the requesting device. Based on the determined geographic region or access network, a networking device returns a specific anycast IP address from which the content may be received. In this manner, the content providing network may utilize multiple anycast IP addresses within the network to provide content to one or more end users of the network. The specific anycast IP address is provided to an end user device to obtain the requested content.

  • CONCURRENT COLLABORATION CONFRENCE PORT MANAGEMENT
    Publication number: 20200280638
    Abstract: Aspects of the present disclosure involve systems and methods for a collaboration conferencing system to track a total number of concurrently utilized ports across any number of conferencing bridges of the network for a particular customer and one or more billing actions may occur based on this tracking. This may result in an alternate billing option for the customer's use of the system. Further, a telecommunications network administrator may provide access to the collaboration conferencing system based on a total number of concurrently utilized ports rather than on a per conference or per minute basis. With the information of the number of purchased ports by the customer, the administrator may more accurately predict an available capacity for the collaboration conferencing system needed to support all of the users of the system and the potential collaboration conferences.

  • Virtual database administrator
    Patent number: 10747732
    Abstract: A virtual database administrator (VDBA) is implemented in a database server network to monitor back-up write events from the database servers on the network to a network back-up server and correct failed back-up attempts. The VDBA regularly polls the database servers for copies of event logs that include information about back-up attempts. The VDBA parses each of the event logs, searching for the back-up log entries indicating successful or failed back-up writes for particular databases. For failed back-up writes, the VDBA instructs the specific database server to retry the back-up write for the particular database. The back-up retry instructions are specific to the database server and cause a back-up retry limited to the particular database on the server that experienced the failure.

  • Service label routing in a network
    Patent number: 10749797
    Abstract: Aspects of the present disclosure involve systems, methods, computer program products, and the like, for implementing and utilizing one or more service labels in a Multiprotocol Label Switching (MPLS) network for delivery service through the network. The general, the service label acts to instantiate a service tunnel between two or more devices of the network, such as between a service or provider edge device and a metro device of the network. The service label is unique and arbitrary label per service to a network device. Once the service tunnel is established between the devices, one or more Internet Protocol (IP) or Ethernet services can be multiplex over the service tunnel to the network device. Also, one or more service labels (tunnels) can be established between any two or more network devices to allow for greater flexibility and scale.

  • STITCHING LABEL-SWITCHED PATHS BETWEEN AUTONOMOUS SYSTEMS WITH INTERNET PROTOCOL ROUTING
    Publication number: 20200259742
    Abstract: Systems and methods for routing traffic through a network along Label-Switched Paths (LSPs) that may extend across multiple autonomous systems include performing Internet Protocol (IP) routing lookups as a packet is transmitted along the LSP. In one implementation, a packet having a predetermined value (which may be inserted by an upstream network device) is received at a network device after travelling along a first segment of an LSP. In response to identifying the predetermined label value of the packet, the network device may perform an IP routing lookup using IP routing information included in the packet to identify a next hop for the packet. The network device may then update a label of the packet such that the packet is routed along a second segment of the LSP and transmit the communication packet to the next hop.
