Abstract: Techniques for the distribution of content objects in a content delivery network (CDN) are disclosed. A CDN distribution server detects a content object's availability and determines whether the content object is a candidate for distribution. The distribution server detects the availability of the content object in response to a provider making new or updated content available at a content site or a location within the CDN. The distribution server obtains identifying information for a candidate content object and determines a select portion of the content object to be distributed within the CDN. The select portion can be a predetermined number of bytes located at a predetermined position in the content object, the size and location of which may be determined according to content-specific mapping data. The distribution server pushes the select portion of the content object to one or more groups of CDN edge servers absent an end-user request.

Abstract: According to the invention, a delivery network for assisting delivery of content objects over an Internet is disclosed. The delivery network includes a network outlet, an interface and a routing function. The network outlet is coupled to a plurality of full-route networks, where each of the plurality of full-route networks is capable of delivering content objects to a plurality of terminal networks. The plurality of terminal networks include a terminal network, where the plurality of terminal networks are coupled to a plurality of end user computers. The interface receives content objects for delivery to the plurality of end user computers. The routing function routes content objects in at least two modes, where a first mode routes content objects based upon a first route path from the network outlet to the terminal network, and a second mode routes at least some content objects using a second route path from the network outlet to the terminal network.

Abstract: A domain name service (DNS) resolver returns Internet protocol (IP) addresses. A connection with an Internet application or device receives domain name resolution requests that originate outside of the Internet. A direct DNS resolver identifies IP addresses without referring to the Internet or using other DNS resolvers. An address store includes a predetermined list of domain names and corresponding IP addresses specified from a point remote to the DNS resolver. The DNS resolver processes the domain name resolutions for the predetermined list of domain names differently than domain name resolutions for other domain names not on the predetermined list of domain names. At least part of the predetermined list is pushed to a destination upon receiving a resolution request for a domain name in the predetermined list of domain names, the request being of a type other than an authoritative resolution request to be performed by the direct DNS resolver.

Abstract: According to the invention, a content delivery network (CDN) for delivering content objects from a content provider to a recipient is disclosed. The CDN includes a dynamic pricing engine and a second web location. The dynamic pricing engine is coupled to a first web location. The first web location, which is associated with a content provider, allows the recipient to order a content object. The delivery quote is solicited by the first web location for delivering a content object one or more times. The second web location delivers the content object to a recipient system of the recipient. The second web location is associated with the dynamic pricing engine. The dynamic pricing engine automatically produces the delivery quote, which is affected by at least one of the content object or a web location of the recipient system.

Abstract: A method, apparatus and system for data transfer is disclosed. For example, settings from multiple entities arranged in a multi-tier control plane are used to set data transfer policies. The policies are use to govern data transfers such as between end users or from an origin server.

Abstract: According to the invention, a method for authenticating download of a number of digital content files ordered from a web site is disclosed. In one step, a selection of the digital content files is received with the web site. Download manager software, media information, the digital content files, and first codes for each of the digital content files are sent to the client computer. The media information indicates a location of each of the number of digital content files. A first code is calculated for each of the digital content files. If the client computer determines that the first code doesn't match a second code for a particular digital content file, it is resent.

Abstract: Systems and methods for gathering distributed information to improve routing that uses Anycast for assigning deliveries between a number of geographically-distant points of presence (POPs) are disclosed. The POPs share the same Internet protocol (IP) address. According to Anycast resolution, the Internet aids in assigning a content request initially to a POP. Delivery statistics are gathered from deliveries a the number of POPs and possibly other sources. Where it is determined that Anycast found the wrong POP, the content request is reassigned to another POP.

Abstract: A method and system for cache optimization in a hybrid solid state drive and magnetic storage cache architecture for a content delivery network (CDN) is disclosed. The CDN has a number of geographically distributed points of presence (POPs) across the Internet. Customers of the CDN pay for storage of content objects. Cache management in a POP analyzes information related to content objects to determine if storage will be on a solid state drive (SSD) instead of a magnetic drive. The information used in this analysis is from the application layer or above in the open systems interconnection (OSI) model. The content objects are delivered from either the SSD or magnetic storage to end users.

Abstract: According to the invention, a content download system for downloading a content file and additional content using a window is disclosed. The content download system includes a content site, a content provider and a third party. The content site presents the window that displays the download progress of the content file, presents the additional content while the content file is downloaded, and allows selection of the additional content. The content provider serves as an origin server for the content file. The third party receives information on the content file and provides the additional content.
