  • System and method of adaptive congestion management
    Patent number: 10833997
    Abstract: A system and method for adaptive congestion management uses measurements of usage of each edge network segment both per-customer and for each edge network segment as a whole. The technique then processes these measurements to determine what changes to make to allowed transfer rates to alleviate congestion. Adaptive congestion management also uses these measurements to determine when to remove any restrictions on transfer rates in the case that the edge network segment is no longer congested.
    Type: Grant

  • Pre-paid service system and method
    Patent number: 9159038
    Abstract: A pre-paid service system configured to provide a subscriber interface to a Subscriber and receive a service level selection from the subscriber, wherein the service level selection includes a capacity limit and/or a time limit. Upon authorization of a payment, the system activates the Subscriber's service. The system also monitors the Subscriber's usage data and time of activation. When the Subscriber's usage data amount or time of activation meets or exceeds the selected service level, the system may deactivate the Subscriber's service.

  • Systems and methods for network content delivery
    Patent number: 9158769
    Abstract: A content delivery system including a subscriber controller and cache, a source controller configured to transmit content to the subscriber controller and cache via a multicast transmission; and a network content delivery controller (NCDC) in communication with the subscriber controller and cache and source controller. A control plane is used to communicate the delivery of control information using Extensible Messaging and Presence Protocol (XMPP) between the subscriber controller and cache, source controller, and NCDC.

  • SYSTEM AND METHOD FOR NETWORK CONTENT DELIVERY
    Publication number: 20110167171
    Abstract: A method and apparatus for distribution of digital content by controlling multicast distribution between caches using XMPP. A content cache manager constructs a database of distributed caches and content sources. Each content source is allocated a multicast address. content sources and multicast addresses are distributed to caches. A cache with a client requesting a matching content source joins the multicast group of the content source to receive content.

  • Method and apparatus for forwarding multicast data by relaying IGMP group membership
    Patent number: 6654371
    Abstract: A method, apparatus and article of manufacture for forwarding multicast data by relaying IGMP group membership. A router is used to build a database of a plurality of interfaces and corresponding multicast groups, and the database is stored on the router. Information from the database is reported upstream to a multicast router. Multicast data is received from the multicast router and distributed to the plurality of interfaces based upon the database.
