Method of distributing files through a content delivery network based also on artificial intelligence algorithms, telematic system and servers that allow to implement it

The method according to claim 2 or 3 or 4 or 5, wherein configuration information is stored in said parent server (1610) at least related to a grandparent Point Of Presence (1700) for said content, wherein the method further comprises the following steps:

• i) (332) said parent server (1610) receives from said neighbour server (1520) a request related to said content,
• then
• l) (333) said parent server (1610) verifies if it possesses a copy of said content or a copy of at least a fragment of said content,
• then
• m) (334-Y) if the verification at step 1 is positive, said parent server (1610) sends to said neighbour server (1520) said copy, and
• (334-N) if the verification at step 1 is negative, said parent server (1610) determines (337) an address of a grandparent server (1710), wherein said address is obtained by performing a mathematical calculation on a name of said content taking into account said configuration information of the parent server (1610), wherein said parent server (1610) belongs to said parent Point Of Presence (1600) and said grandparent server (1710) belongs to said grandparent Point Of Presence (1700) other than said parent Point Of Presence (1600),
• then if the verification at step 1 is negative,
• n) (338) said parent server (1610) sends to said address of grandparent server a request related to said content;
• wherein said grandparent server (1710) is an intermediary server.

An edge server (1510) of a Content Delivery Network (2000), comprising:

• an electronic communication unit adapted to be connected to a telematic network, and
• an electronic processing unit adapted to process data packages received and to be transmitted by said electronic communication unit;
• wherein said electronic processing unit comprises a first storage sub-unit adapted to store contents and/or fragments of contents and a second storage sub-unit adapted to store configuration information related to a home Point Of Presence (1500) of the edge server (1510);
• and
• wherein said electronic processing unit is programmed to deal with content requests, so that in response to a request for a locally possessed content it sends the content and in response to a non-locally possessed content it determines address of a server neighbour (1520) in the same home Point Of Presence (1500) by performing a mathematical calculation on a name of said content taking into account said configuration information, and causes a request related to said content to be sent to said address of neighbour server.

An Intermediary server (1520, 1610) of a Content Delivery Network (2000), including:

• an electronic communication unit adapted to be connected to a telematic network, and
• an electronic processing unit adapted to process data packages received and to be transmitted by said electronic communication unit;
• wherein said electronic processing unit comprises a first storage sub-unit adapted to store contents and/or fragments of contents and a second storage sub-unit adapted to store configuration information related to a home Point Of Presence (1500, 1600) of the intermediary server (1520, 1610) and one or more parent Point Of Presence (1600, 1700) of the intermediary server (1520, 1610);
• and
• wherein said electronic processing unit is programmed to deal with content requests, so that in response to a request for a locally possessed content it sends the content and in response to a non-locally possessed content it determines an address of a parent server (1610, 1710) in a parent Point Of Presence (1600, 1700) by performing a mathematical calculation on a name of said content taking into account said configuration information, and causes a request related to said content to be sent to said address of parent server.

A server (1510, 1520, 1610, 1710) of a Content Delivery Network (2000) comprising:

• an electronic communication unit adapted to be connected to a telematic network, and
• an electronic processing unit adapted to process data packages received and to be transmitted by said electronic communication unit;
• wherein said electronic processing unit comprises a first storage sub-unit adapted to store contents and/or fragments of contents and a second storage sub-unit adapted to store configuration information;
• and
• wherein said electronic processing unit is programmed such to operate as an edge server and/or as an intermediary server.
