Abstract: An edge system receives requests from user devices to retrieves files from an origin server. Instead of retrieving the files as fast as possible, the edge system throttles the retrieval of files to a rate that just exceeds the speed at which the file is played by a browser or media player. The edge system determines an appropriate retrieval rate based on the contents of the file itself. For example, a manifest file associated with the file can indicate a time it takes to play back content and a bitrate of the content. Thus, the edge server can use this information to retrieve a file from an origin server at a rate that is just fast enough to minimize playback interruption. The retrieval rate determined by the edge server therefore does not rely on how fast or slow the user device retrieves the file from the edge server.

Abstract: Systems and methods are described to enable a DNS service to encode information into a network address to be advertised by the DNS service. Information encoded by a DNS service may include, for example, an identifier of a content set to which the network address corresponds (e.g., a domain name) and validity information, such as a digital signature, that verifies the validity of the network address. On receiving a request to communicate with the network address, a destination device associated with the network address may decode the encoded information within the network address to assist in processing the request. In some instances, the encoded information may be used to identify malicious network transmissions, such as transmissions forming part of a network attack, potentially without reliance on other data, such as separate mappings or contents of the data transmission.

Abstract: A system, method, and computer-readable medium for point of presence (POP) based traffic surge detection and mitigation are provided. The system detects a traffic surge for a target group of resources directed at a source POP based on the target group's rank shifts and volume changes among recent time intervals. The system mitigates the detected traffic surge by identifying destination POPs with spare capacity and routing at least a portion of incoming requests for the target group of resources to the destination POPs in accordance with their spare capacities.

Abstract: Systems and methods are described that enable high-data-rate network communications by use of a data transmission system, which can at least partially redirect data transmitted between two computing devices on a public network to a private network. The data transmission system may include a variety of endpoints at different locations, such that source and destination computing devices may pass information into and out of the data transmission system via the endpoints. To ensure that endpoints are able to communication with each computing device via a path of sufficient network quality, the data transmission system may dynamically generate additional endpoints within points of presence of the system. Where no endpoints or points of presence have a connection of sufficient quality to a source and destination computing device, the data transmission system may decline to transmit data, and instruct the source or destination computing devices to utilize traditional communication channels.
