  • Patent number: 11831673
    Abstract: Aspects of the present disclosure involve systems, methods, computer program products, and the like, for an orchestrator device associated with a scrubbing environment of a telecommunications network that receives one or more announced routing protocol advertisements from a customer device under an attack. In response to receiving the announcement, the orchestrator may configure one or more scrubbing devices of the network to begin providing the scrubbing service to packets matching the received routing announcement. A scrubbing service state for the customer may also be obtained or determined by the orchestrator. With the received route announcement and the customer profile and state information, the orchestrator may provide instructions to configure the scrubbing devices of the network based on the received information to dynamically automate scrubbing techniques without the need for a network administrator to manually configure the scrubbing environment or devices.

  • Publication number: 20230370532
    Abstract: Examples described herein relate to standardizing content requests and responses in a content delivery network (CDN). An edge node receives a control object including sets of instructions each implementing portions of a customer’s business logic. The edge node may receive, from a client, a content request identifying a content item, and may apply a set of the instructions which causes the edge node to (i) determine whether any changes are needed for the benefit of a cache server and whether any changes are need for the benefit of an origin server, and (ii) generate a processed client request identifying the content item and including, if needed, any changes for the benefit of the cache server and the origin server. The edge node transmits the processed client request to the cache server, receives a response from the cache server, and transmits a processed client response to the client.

  • Publication number: 20230362092
    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.

    Abstract: Implementations described and claimed herein provide systems and methods for intelligent node type selection in a telecommunications network. In one implementation, a customer set is obtained for a communications node in the telecommunications network. The customer set includes an existing customer set and a new customer set. A set of customer events is generated for a node type of the communications node using a simulator. The set of customer events is generated by simulating the customer set over time through a discrete event simulation. An impact of the customer events is modeled for the node type of the communications node. The node type is identified from a plurality of node types for a telecommunications build based on the impact of the customer events for the node type.

  • Publication number: 20230354039
    Abstract: A security platform of a data network is provided that includes security services for computing devices in communication with the data network. The security platform may apply a security policy to the computing devices when accessing the Internet via a home network (or other customer network) and when accessing the Internet via a public or third party network. To provide security services to computing devices via the home network, the security platform may communicate with a security agent application executed on the router (or other gateway device) of the home network. In addition, each of the devices identified by the security profile for the home network may be instructed or otherwise be provided a security agent application for execution on the computing devices. The security agent application may communicate with the security platform when the computing device connects to the Internet over a third party or public access point.

  • Patent number: 11805184
    Abstract: Aspects of the present disclosure involve a CDN utilizing a Direct Server Return (DSR) request command to create a tunnel from one content server to another content server of the CDN. Through the DSR tunnel, a request for content may be served from a content server that is more advantageous for the CDN for any number of reasons, such as from a content server that is logically closer to the content server. In determining when a DSR tunnel is created to provide the content, the CDN may access a database storing various information concerning the CDN, such as the location of egress gateways of the CDN in relation to one or more content servers, connecting network location information, the capabilities of one or more content servers, and/or load information of available content servers.

  • Patent number: 11805093
    Abstract: Improved methods for retrieval of content from CDNs is provided that includes a rendezvous controller that receives information of an identification of content being requested and an estimated location of a content requesting device. Based on this information, the rendezvous system identifies a server within a CDN from which the requested content may be retrieved. The selected server may be based on a repeatable hash function such that the likelihood that the content being requested is cached at the selected server. Steering requests to a server of the CDN which may have the content cached may reduce the number of servers within the CDN with the same cached content, particularly for the highest requested content. The rendezvous system may then return a corresponding domain name associated with the selected server and that can be subsequently submitted to a DNS for resolution to the IP address of the identified server.

  • Publication number: 20230344875
    Abstract: Novel tools and techniques are provided for implementing monitoring and detection of fraudulent or unauthorized use in telephone conferencing systems or voice networks. In various embodiments, a computing system might monitor call activity through telephone conferencing system or voice network. In response to detecting use of the telephone conferencing system or voice network by at least one party based on the monitored call activity, the computing system might identify incoming and/or outgoing associated with a call initiated by the at least one party. The computing system might analyze the identified incoming and/or outgoing call data to determine whether the call initiated by the at least one party constitutes at least one of fraudulent use or unauthorized use of the telephone conferencing system or voice network. If so, the computing system might initiate one or more first actions.
