  • Multi-tiered server architecture to mitigate malicious traffic
    Patent number: 10834114
    Abstract: A processing system having at least one processor may obtain domain name system (DNS) traffic records of a DNS platform, the DNS traffic records associated with a source device having a first status and that is submitting DNS queries, where a first-tier DNS authoritative server of the DNS platform is configured to forward the DNS queries from the source device to at least a first second-tier DNS authoritative server of the DNS platform designated for the first status. The processing system may further detect anomalous DNS traffic records from the DNS traffic records, identify a change of the source device from a first status to a second status, based upon the detecting the anomalous DNS traffic records, and reconfigure the first-tier DNS authoritative server to redirect the DNS queries from the source device to at least a second second-tier DNS authoritative server designated for the second status.

  • POTS/Packet Bridge
    Publication number: 20050249198
    Abstract: A system and method for bridging the POTS network and a packet network, such as the Internet, uses a set of access objects that provide the interfacing and functionality for exchanging address and payload information with the packet network, and for exchanging payload information with the payload subnetwork and signaling information with the signaling subnetwork of the POTS network.
