System and method for automatically verifying storage of redundant contents into communication equipments, by data comparison

Method for verifying storage of contents into communication equipments connected to at least one communication network, wherein it comprises the steps of, when a first communication equipment stores a content to be audited and has to verify that this content is still stored into a second communication equipment:

• i) transmitting a first request, comprising at least an identifier of said content and first data representative of said content and requiring verification of the storage of said content into said second communication equipment, from the first communication equipment to an auxiliary communication equipment acting as an interface between said communication network and said second communication equipment,
• ii) transmitting a second request, comprising at least said content identifier, from the auxiliary communication equipment to said second communication equipment, to require transmission of second data representative of said content to said auxiliary communication equipment, and triggering a timeout having a chosen duration, and
• iii) if said auxiliary communication equipment has received said second data before expiration of said timeout, comparing in the auxiliary communication equipment said received second data, to said received first data, and if the second data are identical to the corresponding first data, then transmitting a message representative of the result of said comparison to said first communication equipment and indicating that the second equipment stores the audited content,
• and if the second data are not identical to the corresponding first data, then transmitting a message representative of the result of said comparison to said first communication equipment and indicating that the second equipment does not store the audited content.

System for verifying storage of contents into communication equipments connected to at least one communication network, wherein it comprises

• i) interrogation means arranged, when a first communication equipment, to which it is associated, stores a content and wants to verify that this content is still stored into a second communication equipment, for generating a first request, comprising at least an identifier of said content and first data representative of said content and requiring verification of the storage of said content into said second communication equipment, and intended to be transmitted to an auxiliary communication equipment acting as an interface between said communication network and said second communication equipment,
• and ii) processing means arranged, when said auxiliary communication equipment, to which it is associated, has received said first request, for generating a second request, intended to be transmitted to said second communication equipment, comprising at least said content identifier and requiring transmission of second data representative of said content to said auxiliary communication equipment, and for triggering a timeout having a chosen duration, and, if said auxiliary communication equipment has received said second data before expiration of said timeout, for comparing said received second data, possibly after having processed them, to said received first data, and for generating a message representative of the result of said comparison and intended to be transmitted to said first communication equipment indicating if the auxiliary communication equipment stores the content.
