Abstract

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.

Claims17

Dependent claims

A method for operating a telecommunications network comprising:

determining a percentage of storage capacity at a cache node of a content delivery network (CDN);
determining lifetime available writes for the cache node, wherein lifetime available writes comprises a total amount of data that can be written to the cache node before the cache node must be replaced;
scaling a resource caching popularity threshold value based on both the determined percentage of storage capacity at the cache node and cache pressure for the cache node, wherein scaling the resource caching popularity threshold value comprises determining a threshold popularity above which a particular resource will be cached at the cache node, and wherein cache pressure for the cache node is a function of a ratio between total writes to the cache node and the lifetime available writes to the cache node;
caching the particular resource in a cache node storage system when a resource popularity counter exceeds the scaled resource caching threshold value, wherein the cache node storage system comprises a first type of storage drive and a second type of storage drive, the first type of storage drive different than the second type of storage drive;
storing a first resource in the first type of storage drive;
and
storing a second resource different from the first resource in the second type of storage drive.

4 more elements

A networking system comprising:

at least one communication port for receiving requests for content maintained by a content delivery network (CDN);
a storage system for storing content of the CDN, wherein the storage system comprises a first type of storage drive and a second type of storage drive, the first type of storage drive different than the second type of storage drive;
a processing device;
and
a nontransitory computer-readable medium operably connected to the processing device, the nontransitory computer-readable medium configured to store instructions that, when executed by the processing device, cause the processing device to perform the operations of:
determining a percentage of storage capacity at the storage system;
determining lifetime available writes for the storage system, wherein lifetime available writes comprises a total amount of data that can be written to the storage system before the storage system must be replaced;
scaling a content caching popularity threshold value for the storage system based on both the determined percentage of storage capacity and cache pressure for the storage system, wherein scaling the content caching popularity threshold value comprises determining a threshold popularity above which particular content will be cached at the storage system, and wherein cache pressure for the cache node storage system is a function of a ratio between total writes to the cache node storage system and the lifetime available writes to the cache node storage system;
caching the particular content in the storage system when a content popularity counter exceeds the scaled content caching threshold value;
storing a first resource in the first type of storage drive;
and
storing a second resource different from the first resource in the second type of storage drive.
