摘要： Systems, methods, and software for operating a content delivery node to monitor requests for content transferred by at least an end user device to detect when the requests comprise an attack on the content delivery node. Responsive to detecting the attack on the content delivery node, the content delivery node establishes a rate limit in the content delivery node on at least the requests for the content associated with the end user device, and transfers an indication of the attack comprising the rate limit for delivery to another content delivery node that directs the other content delivery node to apply the rate limit to further requests for the content before the further requests are received by the other content delivery node.

摘要： Systems, methods, apparatuses, and software for a content delivery network that caches content for delivery to end user devices is presented. In one example, a method includes assigning prefixed network addresses for the sites of the content delivery network, with ones of the prefixed network addresses indicating associated pathways for routing network traffic to reach the sites over more than one backhaul packet network. The method includes announcing groups of the prefixed network addresses to selected ones of the backhaul packet networks, with each to the groups comprising a backhaul network-independent prefixed network address, a backhaul network-specific prefixed network address, and a failover prefixed network address. The method includes receiving the network traffic at the sites over ones of the backhaul packet networks that are selected among for routing the network traffic by source network addresses indicated in content requests issued from the sites.

摘要： Disclosed herein are methods, systems, and software for modifying a communication path based on latency. In one example, a method of operating a content node to alter a communication path includes identifying latency data for a plurality of end user devices communicating with the content node, and identifying that the one or more end user devices in the plurality of end user devices exceed a latency threshold based on the latency data. The method further includes, in response to identifying that the one or more end user devices in the plurality of end user devices exceed the latency threshold, modifying the communication path between the content node and the one or more end user devices by modifying a domain name system (DNS) configuration for the content node.

摘要： Systems, methods, apparatuses, and software for a content delivery network that caches content for delivery to end user devices is presented. In one example, a method includes establishing domain name relationships for use by a top-level DNS to recurse DNS queries to a DNS node associated with the CDN. The method also includes establishing address correlations between prefixed IPv6 network addresses and PQDNs that comprise indicators for at least a routing provider identifier and a cache node grouping. The method also includes receiving recursed DNS queries and responsively translating domain names in the recursed DNS queries into associated IPv6 network addresses to reach content indicated by the domain names, the associated IPv6 network addresses each determined by at least selecting one of the prefixed IPv6 network addresses according to a desired routing provider and a desired cache node grouping indicated in the PQDNs.

摘要： Described herein are enhancements for operating cache nodes in a content delivery network to synchronize edge dictionary configurations. In at least one implementation, a cache node of a content delivery network receives a content request from an end user device. In response to the request, the cache node identifies a modification to a key-value pair of an edge dictionary, wherein the edge dictionary comprises a reference key-value function for a Hypertext Transfer Protocol (HTTP) accelerator service. The method further provides generating a modified version of the edge dictionary based on the modification, and transferring a notification of the modification to at least one other cache node in the content delivery network.

摘要： Systems, methods, apparatuses, and software for a content delivery network that caches content for delivery to end user devices is presented. In one example, a content delivery network (CDN) is presented having a plurality of cache nodes that cache content for delivery to end user devices. The CDN includes an anonymization node configured to establish anonymized network addresses for transfer of content to cache nodes from one or more origin servers that store the content before caching by the CDN. The anonymization node is configured to provide indications of relationships between the anonymized network addresses and the cache nodes to a routing node of the CDN. The routing node is configured to route the content transferred by the one or more origin servers responsive to content requests of the cache nodes based on the indications of the relationships between the anonymous network addresses to the cache nodes.
