Abstract: A distributed health-check method for web caching in a telecommunication network, wherein a plurality of web caching nodes are coordinated to monitor a set of origin servers where web content is generated. The method includes associating to each user of the telecommunication network requesting the web content buckets as logical containers for holding the web content requested; generating a list of users of the telecommunication network requesting the web content; and performing the plurality of web caching nodes a number of health-checks to the set of origin servers to download the requested web content. A filtering of the set of origin servers is performed for grouping in different areas of interest and the number of health-checks are performed by a limited number of caching nodes receiving the web content requests. The limited number of caching nodes selected belonging to a specific area of interest of the set of origin servers monitoring them.

Abstract: The distribution network comprising a plurality of caching nodes and wherein the web content had been statically identified as an uncacheable content and originated on an origin-server and wherein the method establishes a time to live, TTL, period value to said uncacheable content based on users requests and responds to said users requests by sending to at least to one CDN user said uncacheable content within said TTL period value. Each one of said plurality of caching nodes in said distribution network including a content caching manager and a pseudo-dynamic content TTL predictor and performing the following steps: a) contacting each one of said plurality of nodes with a centralized repository, in order to download the configuration file of a plurality of said CDN users. b) identifying, said content caching manager of each caching node, the uncacheable content as a pseudo-dynamic content; c) predicting, a pseudo-dynamic content TTL predictor of said caching node, said TTL period value in which the uncacheable content will not be modified; and d) caching, each one of said plurality of nodes, the uncacheable content during said predicted TTL period value. The system of the invention is arranged to implement the method of the invention.
