To serve content through a content delivery network (CDN), the CDN must have some information about the identity, characteristics and state of its target objects. Such additional information is provided in the form of object metadata, which according to the invention can be located in the request string itself, in the response headers from the origin server, in a metadata configuration file distributed to CDN servers, or in a per-customer metadata configuration file. CDN content servers execute a request identification and parsing process to locate object metadata and to handle the request in accordance therewith. Where different types of metadata exist for a particular object, metadata in a configuration file is overridden by metadata in a response header or request string, with metadata in the request string taking precedence.

Methods and apparatus for supporting content delivery service are described. In accordance with the invention content can be supplied to temporary storage of a regional or local server used to supply the content to a customer's premises when the requested content is not already available in the regional or local server. A content server hierarchy may be implemented with servers higher up in the hierarchy including more content, e.g., titles, than the number of titles stored in the lower level servers. By storing less frequently accessed content in servers higher in the hierarchy and frequently requested titles lower in the hierarchy, a vast number of titles can be supported without overburdening the storage available at local and regional servers. In addition, a national or other server high in the hierarchy can be used to store, move, and distribute local or other content as part of an on demand service.

A content distribution system has a DNS server which is configured to provide DNS responses in response to DNS requests, and a device which interconnects between a client and the DNS server. The device includes an interface which communicates with the client, and a controller coupled to the interface. The controller can intercept a first DNS request en route from the client to the DNS server, and provide a second DNS request to the DNS server through the interface in response to interception of the first DNS request. The second DNS request selectively includes a client identifier which identifies the client, and not including the client identifier which identifies the client, based on a selection decision. The controller can further convey a DNS response from the DNS server to the client through the interface. The DNS response includes a content server identifier which identifies a content server.

A method and apparatus for determining latency between multiple servers and a client receives requests for content server addresses from local domain names servers (LDNS). POPs that can serve the content are determined and sent latency metric requests. The content server receives the request for latency metrics and looks up the latency metric for the requesting client. Periodic latency probes are sent to the IP addresses in a Latency Management Table. The IP addresses of clients are masked so the latency probes are sent to higher level servers to reduce traffic across the network. The hop count and latency data in the packets sent in response to the latency probes are stored in the Latency Management Table and is used to determine the latency metric from the resident POP to the requesting client before sending the latency metric to the requesting server. The BGP hop count in the Latency Management Table is used for the latency metric upon the first request for an IP address. The latency metric is calculated for subsequent requests of IP addresses using the hop count and RTT data in the Latency Management Table. Latency metrics from POPs are collected and the inverse relationship of the hop counts in a weighted combination with the RTT are used to determine which latency metric indicates the optimal POP. The address of the optimal POP is then sent to the requesting LDNS.

An enforcement architecture and method for implementing digital rights management are disclosed. Digital content is distributed from a content server to a computing device of a user and received, and an attempt is made to render the digital content by way of a rendering application. The rendering application invokes a Digital Rights Management (DRM) system, and such DRM system determines whether a right to render the digital content in the manner sought exists based on any digital license stored in the computing device and corresponding to the digital content. If the right does not exist, a digital license that provides such right and that corresponds to the digital content is requested from a license server, and the license server issues the digital license to the DRM system. The computing device receives the issued digital license and stores the received digital license thereon.

Methods, systems, and computer program products for caching content that has been customized based on one or more operating characteristics of a mobile client. A mobile gateway receives content from a content source and customizes the content using transforms assigned to each mobile client. Transforms account for differences between mobile clients without imposing significant processing burdens on the content server. Copies of the content, the transformed content, and a transform identifier are cached at the mobile gateway so that subsequent requests for the content may be satisfied without requiring access to the content source. Processing that is common among several transforms may be shared. Mobile clients may be any type of computer.

Described are various mechanisms and techniques for influencing or controlling a content update schedule for a content-based software application on a mobile device. A content server issues one or more commands to the mobile device that establish a content update schedule for the mobile device. The mobile device then performs content update sessions with the content server based on that schedule. During any one or more refresh sessions, the content server delivers another command to establish a new content update schedule. This system provides the advantage of allowing the content server to regulate how frequently the mobile device retrieves new content.

A method including communicating with a content server, wherein the communication includes transmitting request data to the content server and receiving first response data associated with the request data; identifying response object data within the first response data; determining whether the response object data is to be downloaded; querying the content server for second response data that corresponds to the response object data based on the determination; transmitting the first response data to a user agent; and storing the second response data, wherein the second response data can be provided to the user agent in a subsequent request.

A secure streaming content delivery system provides a plurality of content servers connected to a network that host customer content that can be cached and/or stored, e.g., images, video, text, and/or software. The content servers respond to requests for customer content from users. The invention load balances user requests for cached customer content to the appropriate content server. A user makes a request to a customer's server/authorization server for delivery of the customer's content. The authorization server checks if the user is authorized to view the requested content. If the user is authorized, then the authorization server generates a hash value using the authorization server's secret key, the current time, a time-to-live value, and any other information that the customer has configured, and embeds it into the URL which is passed to the user. A content server receives a URL request from the user for customer content cached on the content server. The request is verified by the content server creating its own hash value using the customer server's secret key, the current time, a time-to-live value, and any other related information configured for the customer. If the hash value from the URL matches the content server's generated hash value, then the user's request is valid and within the expiration time period and the content server delivers the requested content to the user.

An Internet content delivery network deploys one or more CDN server regions in an enterprise and manages those regions as part of the Internet CDN. In one aspect of the invention, a CDN service provider (CDNSP) deploys one or more CDN regions behind an enterprise's corporate firewall(s). The regions are used to deliver Internet content—content that has been tagged or otherwise made available for delivery over the Internet from the CDN's content servers. This content includes, for example, content that given content providers have identified is to be delivered by the CDN. In addition, the enterprise may tag intranet content, which is then also served from the CDN regions behind the firewall. Intranet content remains secure by virtue of using the enterprise's existing security infrastructure. In accordance with another aspect of the invention, the CDNSP implements access controls and deploys one or more CDN regions outside an enterprise's firewall(s) such that intranet content can be served from regions located outside the firewall(s). In this embodiment, the CDNSP can provide granular control, such as permissions per groups of users. In this way, the CDNSP, in effect, extends a conventional virtual private network (VPN) to all or a portion of the ICDN, thereby enabling the CDNSP to use multiple regions and potentially thousands of content servers available to serve the enterprise's internal content. In addition to making internal content available from the edge of the network, the CDNSP provides a mechanism by which an enterprise may share secure data with its business partner(s) without setting up any special infrastructure.

A scalable domain name system with persistence and load balancing receives requests from client DNS servers or other DNS servers. Each DNS server is associated with a subset of the DNS groups in the network and the invention checks to see if the client DNS server is part of the DNS group that the DNS server is authoritative. If the DNS server is not authoritative for the client DNS server's group, then the request is forwarded to the proper DNS server. The receiving DNS checks to see if a persistent response is required for the request. If a persistent response is required, the appropriate IP address is returned to the requestor. If a persistent response is not required, the load, availability, and latency of the content servers are used to determine the proper content server's address to return to the requestor.

A system and method is provided for integrating and executing smart tags in online content for display by a computing application on a client computer without the deployment of client side code. The computing application includes a helper object and a recognizer/action handler. The computing application requests content from one or more cooperating content servers over a communications network. Upon receipt of the content, the computing application executes the helper object to parse the received content for a smart tag list file, related to the received content. After receiving the smart tag list file, the recognizer/action handler incorporates the smart tags and associated actions from the smart tag list file into the document for display to participating users.

Disclosed is a system for allowing on-demand delivery of data, such as MPEG-2 compressed video data, to a subscriber from a content server. The system utilizes a managed IP network that is coupled to the one or more content servers that allows the content servers to deliver data such as video, audio, and textual data with a guaranteed quality of service that is at least as good as broadcast quality service. The managed IP network is connected to a head end or other local cable service provider where video is delivered locally to subscribers. The IP transport data is translated to MPEG transport data, multiplexed onto an MPEG transport system, digitally modulated onto an rf carrier and up-converted to a specific frequency channel. The signal is then applied to the cable for delivery to the subscriber. Upstream signaling occurs through a set top box or computer that is connected to the cable and subsequently to a digital modulator/demodulator and ISP to a managed IP network 66. Low band signals can also be transmitted from the content servers back to the set top box or computer indicating confirmation of an order. Also, control signals such as stop, rewind, fast-forward, and slow can be transmitted back to the content server to control the transmission of data from the content server to the subscriber.

This invention is related to content delivery systems and methods. In one aspect of the invention, a content provider controls a replacement process operating at an edge server. The edge server services content providers and has a data store for storing content associated with respective ones of the content providers. A content provider sets a replacement policy at the edge server that controls the movement of content associated with the content provider, into and out of the data store. In another aspect of the invention, a content delivery system includes a content server storing content files, an edge server having cache memory for storing content files, and a replacement policy module for managing content stored within the cache memory. The replacement policy module can store portions of the content files at the content server within the cache memory, as a function of a replacement policy set by a content owner.
