Method for communication between a first server and a second server, the first server being designated as the active server for the purpose of communicating with one or more client stations (C1, C2, C3) through a network, said method being based on the use of messages that are in accordance with the Web Services Dynamic Discovery (WS-Discovery) specification and characterized in that the messages are provided with an additional redundancy attribute that allows them to elect the second server as the active server when the first server is no longer the active server, said additional redundancy attribute of a message including at least the following fields: - "UniqueID", which allows a server to be identified on the network when sending said message; - "TypeMessage", which corresponds to the subject of the sent message and which may take three distinct values, which are: ∘ "JOINING", sent by a server when it connects to the network; ∘ "ADVERTISEMENT', sent periodically by the active server to the backup servers in order to inform the backup servers that it is active; ∘ "ELECTION", sent by one or more other backup servers to the other connected servers in order to initiate an election of a new active server; - " AdvertisementTimeout ", which corresponds to the time taken by the active server to transmit messages and which, when it is exceeded, allows the disappearance of the active server to be detected; - " FloatingIPaddress ", which corresponds to a floating IP address assigned to the active server. and in that it includes a step of: - periodically transmitting, by the first server to the second server, a message, the additional redundancy attribute of which includes said "ADVERTISEMENT' field indicating that the first server is the active server, and in that, when the first server no longer transmits this message after the time defined by the "AdvertisementTimeout" field, the method includes a step of: - transmitting, by the second server, a message, the additional redundancy attribute of which includes said "ELECTION" field allowing a new active server to be elected. - "UniqueID", which allows a server to be identified on the network when sending said message; - "TypeMessage", which corresponds to the subject of the sent message and which may take three distinct values, which are: ∘ "JOINING", sent by a server when it connects to the network; ∘ "ADVERTISEMENT', sent periodically by the active server to the backup servers in order to inform the backup servers that it is active; ∘ "ELECTION", sent by one or more other backup servers to the other connected servers in order to initiate an election of a new active server; ∘ "JOINING", sent by a server when it connects to the network; ∘ "ADVERTISEMENT', sent periodically by the active server to the backup servers in order to inform the backup servers that it is active; ∘ "ELECTION", sent by one or more other backup servers to the other connected servers in order to initiate an election of a new active server; - " AdvertisementTimeout ", which corresponds to the time taken by the active server to transmit messages and which, when it is exceeded, allows the disappearance of the active server to be detected; - " FloatingIPaddress ", which corresponds to a floating IP address assigned to the active server. - periodically transmitting, by the first server to the second server, a message, the additional redundancy attribute of which includes said "ADVERTISEMENT' field indicating that the first server is the active server, and in that, when the first server no longer transmits this message after the time defined by the "AdvertisementTimeout" field, the method includes a step of: - transmitting, by the second server, a message, the additional redundancy attribute of which includes said "ELECTION" field allowing a new active server to be elected. - transmitting, by the second server, a message, the additional redundancy attribute of which includes said "ELECTION" field allowing a new active server to be elected.
