Patent number: 11757932Abstract: 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.Type: GrantFiled: October 19, 2022Date of Patent: September 12, 2023Assignee: Level 3 Communications, LLCInventors: Robert Smith, Shawn Marck, Christopher Newton

Patent number: 11750536Abstract: A computer-implemented method on a device. The device has hardware including storage. The method includes obtaining log event data from at least one component or service on the device that is to be delivered to a component or service on a distinct device. Each log event data item has a priority. If a connection to an external location is lost, at least some of the log event data items are selectively stored in the storage, wherein the storing is based on priority of the log event data items. Otherwise, if the connection is not lost, at least some of the log event data items are sent to the at least one external location.Type: GrantFiled: September 21, 2021Date of Patent: September 5, 2023Assignee: Level 3 Communications, LLCInventor: Christopher Newton

Publication number: 20230239376Abstract: A node in a content delivery network (CDN) receives a request for content and determines information about the request. When sufficient information about the content is determined, the request is assigned to an appropriate CD service to process the request; and when insufficient information about the content is determined, the request is assigned to a generic CD service to process the request. The generic CD service processes the request; and provides updated information about the content to be used for processing future requests. An appropriate CD service processing a request may also provide updated information about the content to be used for processing future requests.Type: ApplicationFiled: February 4, 2023Publication date: July 27, 2023Applicant: Level 3 Communications, LLCInventor: Christopher Newton
