Abstract: Methods and systems for facilitating content accessibility via different communication formats are provided. According to one embodiment, a method is provided for directing content requests to an appropriate server. Information indicative of one or more communication formats via which a client device is capable of communication is caused to be stored on a client device by (i) sending to the client device a web page having embedded therein one or more of IPv4 and IPv6 test content; and (ii) based on a response to the test content, determining communication capabilities of the client device. A result of the determination is stored within a browser cookie, which is sent to the client device. A content request is received from the client device that includes the browser cookie. The request is redirected to a server appropriate for the communication capabilities of the client based at least in part on the cookie.

Abstract: Methods and systems for facilitating content accessibility via different communication formats are provided. According to one embodiment, a method is provided for directing content requests to an appropriate content delivery network. A content request is received from a client.

Abstract: Crowd based content delivery is disclosed. In some embodiments, managing content delivery includes receiving a specification from a resource provider of an availability of a content delivery service at the resource provider, selecting the resource provider to service requests for a content item, facilitating caching of the content item at the resource provider, and redirecting a request for the content item to the resource provider for servicing.

Abstract: Methods and systems for redirecting content requests are provided. According to one embodiment, a subscription request from a publisher is received by a redirect host. The subscription request includes a content delivery policy and requests the redirect host to service requests for content published by the publisher. The content is hosted by servers of the publisher residing within a private network. A client request is received by the redirect host for content. It is determined based on the content delivery policy whether to select a publisher server to service the request. If not, then: (i) a redirection is made to a registered resource provider of a CDN configured to deliver content on behalf of the publisher; and (ii) information is logged to facilitate billing of the publisher and reimbursement of the registered resource provider; otherwise, a redirection is made to the selected server.

The content request relates to web page content published by a content publisher in an Internet Protocol version 4 (IPv4) format or an Internet Protocol version 6 (IPv6) format that is obtained by the content delivery network from the content publisher and is translated to the other format by the content delivery network prior to receiving any content requests for the web page content. A communication format through which the client is capable of communicating is determined. The content request is directed to a content delivery network that supports the communication format through which the client is capable of communicating.

Abstract: Methods and systems for redirecting client requests are provided. According to one embodiment, a system includes a processor and a memory coupled to the processor and configured to provide the processor with instructions. A request is received from a client capable of communicating via multiple supported communication formats. The request is capable of being serviced by multiple servers each of which are configured to communicate via a different communication format. A server is selected from the multiple servers based on a traffic management policy. The traffic management policy is based on (i) different communication formats available via the multiple servers and (ii) performance expected to be provided to the client as a result of using each of the different communication formats. The client is then redirected to the selected server.

The content request is directed to a content delivery network that supports the communication format through which the client is capable of communicating.

Abstract: Methods and systems for routing client requests are provided. According to one embodiment, a request handling server facilitates servicing of client requests for content published by a content publisher. A Domain Name System (DNS) service and a web service are provided by the request handling server. A rule for managing services provided by the request handling server to the content publisher is obtained by the request handling server. One or both of the DNS service and the web service are enabled by the request handling server for the content publisher based on the rule.

Abstract: IP reflection comprising double static NAT (network address translation) is disclosed. In some embodiments, a packet having a public IP address is received at a protecting network. The public IP address of the packet is translated to a corresponding protected IP address associated with a protected network, and the packet is forwarded to the protected network for servicing. The protected IP address of a response to the packet from the protected network is translated back to the public IP address at the protected network before sending.

Abstract: Managing TCP anycast requests at content delivery network nodes is disclosed. In some embodiments, serving a request includes receiving a request at a node of a plurality of nodes comprising a content delivery network, wherein each of the plurality of nodes share a same anycast IP address to which the request is directed and servicing the request at the node.
