This disclosure describes systems, methods, and devices related to managing egress traffic from a network to one or more peer networks. A method may include generating, using a load balancer of a network, a dynamic logical egress traffic threshold for a peer network; determining, using the load balancer, that first traffic from the network to the peer network is below the logical egress traffic threshold; directing second traffic from the network to the peer network based on the determination that the first traffic is below the logical egress traffic threshold; determining, using the load balancer, that the second traffic from the network to the peer network has reached the logical egress traffic threshold; and directing third traffic from the network away from the peer network based on the determination that the second traffic has reached the logical egress traffic threshold.

Enhanced management of egress traffic to a peer communications network

Provided is a content delivery method and architecture for ways to improve the caching of content at one or more content providing devices of a Content Delivery Network (CDN). In particular, systems and methods are disclosed that vary the requirements to store resources or content within a caching device using a dynamic popularity threshold. This popularity threshold may be varied based on a measured fullness of the storage capacity of the cache device. In another example, the dynamic popularity threshold may be further varied based on a cache pressure, which is an indication of how often the cache replaces stored items with new items. The adjustment to the popularity threshold for caching particular content at the caching device may thus be based on a number of requests for content received at the device to tune the caching procedure for a particular region of the CDN.

System and method for improvements to a content delivery network

A content delivery method, and related apparatus, that involves the operations of receiving a request for a content resource including at least one embedded resource with a tag. Upon identification of the tag, using at least one delivery parameter to generate a modified embedded resource. Embedding the modified embedded resource in a content resource, such as an HTML document. Delivering, such as in response to request from a browser, the content resource with the modified embedded resource.

Network address resolution

The present application describes a system and method for determining a latency between a client device and various servers of a networking system.

Network optimization system using server latency measurements

Examples described herein relate to standardizing content requests and responses in a content delivery network (CDN). An edge node receives a control object including sets of instructions each implementing portions of a customer's business logic. The edge node may receive, from a client, a content request identifying a content item, and may apply a set of the instructions which causes the edge node to (i) determine whether any changes are needed for the benefit of a cache server and whether any changes are need for the benefit of an origin server, and (ii) generate a processed client request identifying the content item and including, if needed, any changes for the benefit of the cache server and the origin server. The edge node transmits the processed client request to the cache server, receives a response from the cache server, and transmits a processed client response to the client.

Uniformity of instructions for content requests and responses in a content delivery network

A computer-implemented method, in a content delivery (CD) network that delivers content on behalf of multiple content providers. The method includes, at a server in the CDN, wherein the server is currently processing at least one other request in at least one other session: receiving a connection request from a client, the connection request being associated with a corresponding content request; determining whether handling the content request will cause the server to become overloaded; and, based on the determining in (B) and on information about the content request, conditionally (i) accepting the content request, and (ii) terminating or throttling at least one session on the server.

Predictive load mitigation and control in a content delivery network (CDN)

Examples described herein relate to systems and methods for tiered updating of configuration data. Updated configuration data is transmitted to different tiers of nodes. The nodes of a first tier are commanded to use the updated configuration data. After waiting to see if any nodes of the first tier communicate a fault after using the updated configuration data, for each of the additional tiers in the CDN it is sequentially repeated to: transmit a command to the nodes of that additional tier to use the updated configuration data; and after waiting to see if any nodes of any tier communicate a fault after using the updated configuration data, transmitting a command to the nodes of another additional tier to use the updated configuration data.

Tiered updating of configuration data in a content delivery network

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.
