Abstract

A method for distributing long-tail content, including the steps of: a) loading, a first user, into a local PoP to which said first user is remotely connected an amount of long-tail content to be distributed and shared; and b) geo replicating, at selected times, the amount of long-tail content to a at least one remote PoP, to which at least a second user is remotely connected, by pushing said amount of content to be distributed and shared to the at least one remote PoP. The method including selecting, before performing steps a) and b), the at least second user, based on the probability that the amount of long-tail content generated by the first user will be requested by the at least second user, the probability being estimated by historical preference information generated between the first user and the at least second user.

Claims

1. A method for distributing long-tail content, comprising the steps of:

a) loading, a first user, into a local PoP to which said first user is remotely connected an amount of long-tail content to be distributed and shared; and

b) geo replicating, at selected times, said amount of long-tail content to a at least one remote PoP, to which at least a second user is remotely connected, by pushing said amount of content to be distributed and shared to said at least one remote PoP,

said method comprising selecting, before performing said steps a) and b), said at least second user, based on the probability that said amount of long-tail content generated by said first user will be requested by said at least second user, said probability being estimated by means of a historical preference information generated between said first user and said at least second user.

2. The method of claim 1, comprising calculating said selected times for amount of long-tail content geo replication of step b) based on an expected time of consumption by said at least second user.

3. The method of claim 2, further comprising estimating said selected times based on a network traffic condition in order to use bandwidth at outside peak consumption times.

4. The method of claim 1, wherein said historical preference information is based on social information from past history interactions taken from a social network established between said first user and said at least second user.

5. The method of claim 4, wherein said historical preference information further comprises information related to the location of said at least a second user.

6. The method of claim 1, wherein said probability is measured by the ratio of the total of said amount of long-tail content requested by said at least second user divided by the total of said amount of long-tail content generated by said first user.

7. The method of claim 1, comprising computing the distance from said at least a second user to said at least one remote PoP for performing said step b).

8. The method of claim 7, wherein said distance between said at least a second user and said at least one remote PoP is computed using a Haversine distance.

9. The method of claim 1, wherein said amount of long-tail content to be distributed and shared is pushed to said at least a second user through the nearest of at least one remote PoP.

10. The method of claim 1, wherein a dataset comprising said historical preference information is used for characterising users activity patterns by means of collecting said users social information from said social network between said first user and said at least second remote user.

11. The method of claim 1, comprising defining a penalty system in order to evaluate the latency time for receiving said amount of long-tail content by said at least second user from said first user.

12. The method of claim 1, comprising scheduling said amount of long-tail content to be distributed and shared by exploiting time-zone differences.

13. The method of claim 12, wherein said long-tail content is scheduled by an heuristic algorithm, said heuristic algorithm considering loading said long-tail content on different links to be divided into discrete time bins and finding said time bins in the future in which said long-tail content will be accessed.

14. The method of claim 1, wherein said steps a) and b) are performed through a plurality of transactions per second between said first user and several of said second users.
