  • Patent number: 11122117
    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.

  • Publication number: 20210281472
    Abstract: Examples described herein relate to systems and methods for containing a faulty stimulus. A computer-implemented method may include listing in a suspect list every received stimulus including the faulty stimulus, and implicitly testing the stimuli by respectively acting upon those stimuli by a software application. Responsive to successfully acting upon each of the stimuli besides the faulty stimulus, each non-faulty stimulus is deleted from the suspect list and, responsive to such deletion, made available to a downstream node. Responsive to acting upon the faulty stimulus, the software application crashes which leaves the faulty stimulus listed in the suspect list. The software application then restarts and deems the faulty stimulus as being faulty based upon the faulty stimulus still being listed in the suspect list after the restart.

  • Publication number: 20210281542
    Abstract: Examples of the present disclosure relate to hostname pre-localization. In examples, a service uses a content distribution network (CDN) to provide at least a part of the computing functionality associated with the service. A pre-localized hostname may be used to direct the client computing device to a specific edge server of the CDN that is associated with the computing functionality. In examples, a service receives an initiation request from a client computing device for the computing functionality provided by the CDN. The service generates a pre-localization request comprising pre-localization information and provides the pre-localization request to the CDN. Accordingly, the CDN generates a pre-localized hostname associated with an edge server based on the pre-localization information. The pre-localized hostname is provided to the service, which is then provided to the client computing device, thereby directing the client computing device to the specific edge server of the CDN.

  • Patent number: 11115435
    Abstract: Implementations described and claimed herein provide systems and methods for mitigating network threats. In one implementation, a provider edge device of a telecommunications network is configured to accept distributed denial of service mitigation rule propagation from a customer edge device of a customer network in communication with the provider edge device. A distributed denial of service mitigation rule for the customer network is received at the provider edge device from the customer edge device. The distributed denial of service mitigation rule includes one or more routing parameters and a mitigation action. The distributed denial of service mitigation rule is implemented locally on the provider edge device of the telecommunications network. A broadcasting of the distributed denial of service mitigation rule in the telecommunications network is prevented beyond the provider edge device.

  • Patent number: 11108801
    Abstract: In an embodiment, a computer implemented method receives flow data for a network flows. The method extracts a tuple from the flow data and calculates long-term and short-term trends based at least in part on the tuple. The long-term and short-term trends are compared to determine whether a potential network anomaly exists. If a potential network anomaly does exist, the method initiates a heavy hitter detection algorithm. The method forms a low-complexity intermediate stage of processing that enables a high-complexity heavy hitter detection algorithm to execute when heavy hitters are likely to be detected.

  • Publication number: 20210266342
    Abstract: Aspects of the present disclosure involve systems, methods, computer program products, and the like, for providing a proxy server or scrubbing service for an authoritative domain name server (DNS) of a CDN to prevent or otherwise mitigate attacks on the server. The proxy server may receive incoming requests to the authoritative DNS and determine which requests are valid and which are potentially part of an attack on the network. In one embodiment, the proxy server may then “scrub” or otherwise remove the requests of the attack to mitigate the effect of the attack on the network. For example, the proxy server may ignore the request, may direct the request to a “dead-end” server or other device to prevent overloading of the target device, may instruct a device from which the request was sent to discard the request, etc.

  • Publication number: 20210243225
    Abstract: Embodiments provide system and methods for a DDoS service using a mix of mitigation systems (also called scrubbing centers) and non-mitigation systems. The non-mitigation systems are less expensive and thus can be placed at or near a customer's network resource (e.g., a computer, cluster of computers, or entire network). Under normal conditions, traffic for a customer's resource can go through a mitigation system or a non-mitigation system. When an attack is detected, traffic that would have otherwise gone through a non-mitigation system is re-routed to a mitigation system. Thus, the non-mitigation systems can be used to reduce latency and provide more efficient access to the customer's network resource during normal conditions. Since the non-mitigation servers are not equipped to respond to an attack, the non-mitigation systems are not used during an attack, thereby still providing protection to the customer network resource using the mitigation systems.
