摘要

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 comprising associating to each user of said telecommunication network requesting said web content buckets as logical containers for holding said web content requested; generating a list containing all of said users of the telecommunication network requesting said web content; and performing each of said plurality of web caching nodes a number of health-checks to said set of origin servers to download said requested web content. Moreover, a filtering of said set of origin servers is also performed, so that they are grouped in different areas of interest and said number of health-checks are also performed by a limited number of caching nodes receiving said web content requests. Said limited number of caching nodes being selected belonging to a specific area of interest of said set of origin servers monitoring them.
