A method for managing storage of data objects in a peer-to-peer system including a plurality of peer entities is provided. For each data object to be stored into the peer-to-peer system, the method including establishing a group of peer entities so that the group meets a stability requirement according to predetermined stability rules, storing the data object into each peer entity of the group, and each peer entity of the group generating and maintaining a group list associated with the data object, which includes the peer entities of the group.

Method and system for data management in peer-to-peer network

To measure the quality of service at the application level in a telecommunication network (N), a function (A) is provided for carrying out sessions at the application level on said network (N). Through this activation function (A), sessions are then carried out, measuring (F) and also storing (Hin a set of points (S, . . . , S, S) of the network (N) data indicative of the behavior of said network. The possible occurrence of critical situations relating to quality of service is verified (B) and, upon the occurrence of a said critical situation, a trigger signal (Trigger) is generated. By effect of the generation of said trigger signal, the data indicative of the behavior of the network measured and stored in the aforesaid set of points of the network (N) are collected in centralized fashion (H). The data thus collected are indicative of the end-to-end quality of service of the network (N) itself. Preferential application to packet networks like mobile telephony network such as GPRS or UMTS networks.
