A method for distributing content data packages 7 originated by users of a super peer-to-peer network is proposed, wherein the content data packages 7 are to be cached in caching nodes CN1,CN2,CN3,CN4 of said network. The network comprises a plurality of caching nodes CN1,CN2,CN3,CN4 and user nodes 5 of said users and a plurality of data lines that extend between adjacent of said nodes and the users are being grouped in user groups and listed in a user group list. Content data traffic is to be delivered on traffic connections between user nodes 5 of the network. The method comprises the steps of: a) receiving a request for uploading an upload content data package 7 from a requesting user of the users by an agent network node of said network, b) looking up all user group members of the users being member of a current user group UG1 of said requesting user in said user group list and determining the user nodes of said user group members, c) determining in which of the caching nodes CN1,CN2,CN3,CN4 of the network said upload content data package 7 is to be cached by applying a decision matrix, wherein said decision matrix defines a relationship defining at which caching node content data packages 7 have to be cached for which user node, d) caching said upload content data package 7 in the determined caching nodes CN1,CN2,CN3,CN4.
