摘要： A content delivery network (CDN) for providing content objects and domain resolution. The CDN includes a connection with a terminal device, a second domain name service (DNS) system, an IP address store for holding authoritative Internet protocol (IP) addresses, and a content store holding at least one of the first or second content object. A first request to resolve a first domain name is received by the second DNS system at a second location. A second request to resolve a second domain name is received by the second DNS system at the second location. The first domain name is associated with a first content object, and the second domain name is associated with a second content object. The first and second requests are relayed with the terminal device, which receives Internet access from an access network. The access network comprises a first DNS system that functions in a recursing DNS mode. The content object is realized in a first location that is different from the second location of the terminal device. The second DNS system operates in a recursing DNS mode to retrieve a first IP address corresponding to the first domain name. The first IP address for the first domain name is returned from the second DNS system to the terminal device to fulfill the first request. The second DNS system operates in an authoritative DNS mode to retrieve a second IP address from the IP address store. The second IP address for the second domain name is returned from the second DNS system to the terminal device to fulfill the second request.

摘要： A content delivery network (CDN) for delivering content over the Internet is disclosed in one embodiment. The CDN is configured to deliver content for others and includes a domain resolution service (DNS) server, caching servers and an Internet interface. The DNS server receives a first domain resolution request and produces a first DNS solution, and receives a second domain resolution request and produces a second DNS solution. The first and second domain resolution requests correspond to a same domain. The caching servers correspond to a plurality of addresses. The interface receives domain resolution requests, which include the first and second domain resolution requests, and transmits DNS solutions, which include the first and second DNS solutions. The first DNS solution comprises a first plurality of addresses corresponding to at least a first subset of the plurality of caching servers, and the second DNS solution comprises a second plurality of addresses corresponding to at least a second subset of the plurality of caching servers. The first DNS solution is different from the second DNS solution in that the second subset includes an address for a caching server not in the first subset. The second subset is chosen to generally match a processing power of the first subset.

摘要： 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.

摘要： One or more content delivery networks (CDNs) that deliver content objects for others is disclosed. Content is propagated to edge servers through hosting and/or caching. End user computers are directed to an edge server for delivery of a requested content object by a universal resource indicator (URI). When a particular edge server does not have a copy of the content object from the URI, information is passed along a hierarchy (to a parent server, grandparent server, and, eventually, an origin server) until the content object is found. The origin server may be hosted in the CDN or at a content provider across the Internet. Once the content object is located in the hierarchical chain, the content object is passed back down the chain to the edge server for delivery. Optionally, the various servers in the chain may cache or host the content object as it is relayed.
摘要翻译： 公开了一种或多种传送其他内容对象的内容传送网络（CDN）。 内容通过托管和/或缓存传播到边缘服务器。 最终用户计算机被引导到边缘服务器以通过通用资源指示符（URI）递送所请求的内容对象。 当特定的边缘服务器没有来自URI的内容对象的副本时，信息将沿着层次结构（到父级服务器，祖父服务器，最终为源服务器）传递，直到找到内容对象。 原始服务器可以被托管在CDN中或通过因特网的内容提供商处。 一旦内容对象位于分层链中，内容对象就会从链中传回到边缘服务器进行传递。 可选地，链中的各种服务器可以在内容对象被中继时缓存或主持内容对象。

摘要： One or more content delivery networks (CDNs) that deliver content objects for others is disclosed. Content is propagated to edge servers through hosting and/or caching. End user computers are directed to an edge server for delivery of a requested content object by a universal resource indicator (URI). When a particular edge server does not have a copy of the content object from the URI, information is passed to another server, the ancestor or parent server to find the content object. There can be different parents servers designated for different URIs. The parent server looks for the content object and if not found, will go to another server, the grandparent server, and so on up a hierarchy within the group. Eventually, the topmost server in the hierarchy goes to the origin server to find the content object. The origin server may be hosted in the CDN or at a content provider across the Internet. Once the content object is located in the hierarchical chain, the content object is passed back down the chain to the edge server for delivery. Optionally, the various servers in the chain may cache or host the content object as it is relayed.

摘要： A content delivery network (CDN) for delivering content over the Internet is disclosed in one embodiment. The CDN includes a domain resolution service (DNS) server, caching servers and an Internet interface. The caching servers correspond to a plurality of addresses. The DNS server receives two domain resolution requests corresponding to a same domain and produces two different DNS solutions, each corresponding to a subset of caching servers. The interface receives domain resolution requests, including the two domain resolution requests, and transmits DNS solutions, including the two DNS solutions. The processing power is generally matched between the two DNS solutions.
