摘要： Some embodiments implement systems and methods to monitor CDN performance from the end user's perspective. To achieve full end-to-end monitoring, the systems and methods monitor the performance of Anycast routing for routing an end user to the optimal PoP of the CDN and monitor the performance of different routes that deliver content from the optimally selected PoP back to the end user. Systems and methods are also provided to leverage the monitored performance in order to automatically optimize the performance of the CDN by optimizing or modifying Anycast routing and by performing route grooming as needed to ensure that the optimal route is selected to deliver content to different sets of end users that request content from a particular PoP.

摘要： Some embodiments provide a reconfigurable tool for managing the downloading of content from, while reporting information to, various content providers and Content Delivery Networks (CDNs) through a single installed instance of the reconfigurable tool. In some embodiments, the tool includes a container application that is used to download content that is supplied by various content providers. The tool also includes a configuration file. The configuration file configures operation of the application to download content from a particular content host. The configuration also specifies reporting parameters that identify what information to report, when to report the information, and to whom the information is reported as part of the content download. Using this tool, content providers and CDNs are able to provide customizable and unique user experiences without modifying the code base of the application and without having to develop and maintain their own proprietary download manager applications.

摘要： Some embodiments provide a capacity management agent that modifies bandwidth that is allocated between an end user and a carrier network by caching requested content that is streamed at a first rate and then providing the cached content to the end user through the carrier network at a second rate. The agent performs a process that includes receiving data intended for a service region of the carrier network from an external data network. The process identifies resource availability at the service region. Next, the process passes the data to the service region at the first rate when the resource availability at the service region is not less than a threshold amount and caches the data for passing to the service region at the second rate that consumes fewer carrier network resource than the first rate when the resource availability at the service region is less than the threshold amount.

摘要： Some embodiments provide a capacity management agent that modifies content requests to adjust bandwidth consumption when streaming requested content from a content provider to a requesting user. The modifications include modifying a URL or header information of the request. The agent performs a process that receives a request for content of a content provider. The process identifies a parameter of the carrier network and modifies the request when the parameter satisfies a threshold. The process passes the request to the content provider and the content provider provides content that consumes a first set of resources in response to an unmodified request and a second set of resources in response to a modified request. When the parameter identifies congestion, the first set of resources is greater than the second set of resources. When the condition parameter identifies underutilization, the first set of resources is less than the second set of resources.

摘要： Some embodiments provide different frameworks that implement conflict avoidance systems and methods for ensuring uniqueness in identifying assets for different customers that are deployed to server capacity of one or more distributed platforms participating in a federation. Specifically, different frameworks are provided whereby the distributed platforms authorize use of a domain before configuring the domain to identify assets of a customer. A method performed in one such framework includes receiving a domain that is specified for identifying assets of a first customer belonging to a first distributed platform of the federation. The method determines whether the domain conflicts with a domain that is configured by a second distributed platform of the federation. The method then communicates with the first distributed platform (i) to configure the received domain when there is no conflict and (ii) to prevent the first distributed platform from configuring the received domain when there is a conflict.

摘要： Some embodiments provide a director agent, a server agent, and a specialized hand-off protocol for improving scalability and resource usage within a server farm. A first network connection is established between a client and the director agent in order to receive a content request from the client from which to select a server from a set of servers that is responsible for hosting the requested content. A second network connection is established between the server agent that is associated with the selected server and a protocol stack of the selected server. The first network connection is handed-off to the server agent using the specialized hand-off protocol. The server agent performs network connection state parameter transformations between the two connections to create a network connection through which content can be passed from the selected server to the client without passing through the director.

摘要： Some embodiments provide systems and methods for implementing discrete mapping for targeted caching in a carrier network. In some embodiments, discrete mapping is implemented using a method that caches content from a content provider to a caching server. The method modifies a DNS entry at a particular DNS server to resolve a request that identifies either a hostname or a domain for the content provider to an address of the caching server so that the requested content is passed from the cached content of the caching server and not the source content provider. In some embodiments, the particular DNS server is a recursive DNS server, a local DNS server of the carrier network, or a DNS server that is not authoritative for the hostname or domain of the content provider.

摘要： Some embodiments provide a capacity exchange whereby capacity from different content delivery networks (CDNs) can be bought, sold, and traded. The capacity exchange is part of an “Open CDN” platform. The Open CDN platform federates the independent operation of CDNs and other operators of and service providers to distributed platforms participating in the Open CDN platform so that each participant can (1) dynamically scale its capacity without incurring additional infrastructure costs, (2) expand its service into previously untapped geographic regions without physically establishing points of presence (POPs) at those geographic regions, and (3) reduce sunk costs associated with unused capacity of already deployed infrastructure by selling that unused capacity to other participants that are in need of additional capacity. The Open CDN platform includes one or more APIs for facilitating intercommunication between the federation participants by performing configuration mapping, command interoperability, traffic management, and reporting aggregation.
