Aspects of the present disclosure involve a CDN utilizing a Direct Server Return (DSR) request command to create a tunnel from one content server to another content server of the CDN. Through the DSR tunnel, a request for content may be served from a content server that is more advantageous for the CDN for any number of reasons, such as from a content server that is logically closer to the content server. In determining when a DSR tunnel is created to provide the content, the CDN may access a database storing various information concerning the CDN, such as the location of egress gateways of the CDN in relation to one or more content servers, connecting network location information, the capabilities of one or more content servers, and/or load information of available content servers.

Content delivery systems and methods

Aspects of the present disclosure include a content delivery network (CDN) for delivering content associated with a plurality of different types of applications/devices. Using a CDN flow application, a plurality of network flow parameters are generated for content delivery unique to different types of applications or devices. The network flow parameters include customized data transmission rates. The network flow parameters include predetermined settings for transmission control protocol (TCP) connections between the CDN and devices using a TCP flow control mechanism. Upon receiving a content request, the CDN fulfills the content request based upon first network flow parameters. The network flow parameters may be adjusted for each of the plurality of different types of applications/devices. The network flow parameters may be generated based upon requests or based upon the performance of each of the plurality of applications/devices.

Network flow control

Embodiments generally disclosed herein include a computer-implemented method for monitoring and correlating network traffic data associated with a primary network that is in communication with a plurality of secondary networks. The method generates a network traffic data set by monitoring network traffic between the primary network and the plurality of secondary networks. The method also determines a mapping of network connectivity by monitoring inter-network routing information between the primary network and the plurality of secondary networks. In addition, the method generates a traffic measurement data set by monitoring network utilization statistics between the primary network and the plurality of secondary networks. With the collected data sets, the method then calculates a relational network mapping between the primary network and the plurality of secondary networks by correlating the network traffic data set, the mapping of network connectivity, and the traffic measurement data set.

Embodiments herein include methods and systems for use in delivering resources to a client device over a local network. An exemplary system comprises a plurality of caching devices operable to cache resources on behalf of a plurality of content providers, and a local caching device communicatively situated between an access network and the client device, wherein the access network is communicably situated between the plurality of caching devices and the local caching device. The local caching device is operable to retrieve a requested resource from at least one of the plurality of caching devices, deliver the requested resource to the client device over the local network, and store the requested resource for future requests by other client devices.

Content delivery network with deep caching infrastructure

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for a content delivery network (CDN) architecture utilizing one or more proxy cache devices between a requesting device and an edge cluster of the CDN. The proxy cache device is a relatively high-speed device compared to various possible devices making up one or more edge clusters. Thus, if the proxy has cached the requested content, it is capable of directly servicing the client content request at a faster rate than providing the content from the edge cluster. Otherwise, the proxy cache may request the content from an edge cluster and store the content for quick retrieval in response to additional requests for the content. In one embodiment, the proxy cache may perform an analysis of the request or a series of requests to determine if the content is cached at the proxy cache device.

Content delivery system and method using anycast or unicast address

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for managing the distribution of content from a content distribution network (CDN). In general, the system receives a request for content from the CDN from a user of the network and determines a server within the CDN to provide the content to the user. In addition, the system of the present disclosure may determine a preferred server or group of servers from which the content is provided to the user. This preference may be based on information received from a Border Gateway Protocol feed or Interior Gateway Protocol feed and one or more business determinations, such as the cost of providing the content through the CDN and particular egress port associated with the CDN.
