  • Patent number: 11968174
    Abstract: Systems and methods for blocking spoofed traffic within communications networks include obtaining, at a computing system, routing information for an autonomous system of a communications network, the routing information identifying Internet Protocol (IP) addresses associated with the autonomous system. In response to receiving the routing information, the computing system generates a prefix list based on the routing information, the prefix list including one or more prefixes encompassing the IP addresses identified by the routing information. The computing system then transmits instructions to a network device of the communications network configured to cause the network device to update a filter function of the network device based on the prefix list such that the network device permits network traffic that originates from IP addresses within the prefixes of the prefix list.

  • Publication number: 20240129225
    Abstract: Aspects of the present disclosure involve systems, methods, computer program products, and the like, for providing multiple egress points from a telecommunications network for a client of the network. In particular, the process and system allows for multiple provider edges of the network to utilize a route reflector server to provide a border gateway protocol (BGP) route to other provider edges in the network. Further, the multiple provider edges may each announce similar interior gateway protocol (IGP) routes through the network such that a provider edge receiving a packet intended for the customer network may select from the multiple IGP routes to provide the intended packet to the customer network. In this manner, the receiving provider edge may load balance among the various connections of the customer network to the telecommunications network.

  • Publication number: 20240113964
    Abstract: Novel tools and techniques are provided for implementing name-based routing through networks. In various embodiments, a broker manager in each of a plurality of networks may receive a subscription request for a network device from a client device, each device being locally accessible or disposed in an upstream or downstream network. The broker manager uses its client broker to communicate with a locally accessible client device, and uses its mediator broker (and, sometimes, an intermediate device(s)) to communicate with a locally accessible network device. The broker manager otherwise uses its messaging brokers to communicate with control channels of one or more networks. Once subscription with the network device has been established, any commands and responses between the client device and the network device may be routed over pub/sub channels via the broker managers and their brokers using name-based routing, without routing based on IP address of the network device.

  • Patent number: 11943239
    Abstract: Novel tools and techniques are provided for implementing fraud or distributed denial of service (“DDoS”) protection for session initiation protocol (“SIP”)-based communication. In various embodiments, a computing system may receive, from a first router, first SIP data indicating a request to initiate a SIP-based media communication session between a calling party at a source address and a called party at a destination address. The computing system may analyze the received first SIP data to determine whether the received first SIP data comprises any abnormalities indicative of potential fraudulent or malicious actions. If so, the computing system may reroute the first SIP data to a security deep packet inspection (“DPI”) engine, which may perform a deep scan of the received first SIP data to identify any known fraudulent or malicious attack vectors contained within the received first SIP data. If so, the security DPI engine may initiate mitigation actions.

  • Patent number: 11936550
    Abstract: A routing system can provide a Dynamic-Hybrid Forwarding Information Base (DHFIB). A control component of the routing system can build a routing table that includes routing information (e.g., prefixes, addresses, etc.) for use by a first routing component. The routing table can be ordered or ranked based on traffic information from the first routing component. Then, the control component can create the DHFIB from the routing table, wherein the DHFIB is a portion of the routing table and related to the first routing component. As such, the portion of the routing table selected for the DHFIB can be the set of prefixes in the routing table that represent the most frequently routed or most important prefixes in the routing table. Finally, the control component can forward the DHFIB to the first routing component to allow the routing component to route communications.
