Processing of Messages to be Transmitted Over Communication Networks

A method for processing messages to be transferred between a transmitting entity and a receiving entity at least partially over a communication network, the method comprising the steps of

• obtaining, to the transmitting entity, a message to be transferred to the receiving entity,
• defining a substantially unique identifier at least for one part of the message to be transferred, a definition of the substantially unique identifier being based on the content of a part of the message,
• replacing said part of the message with said substantially unique identifier in a condition that the part of the message is previously transferred to the receiving entity, and
• forwarding the message for transfer to the receiving entity.

A transmitting entity (600) adapted for processing messages to be transferred between the transmitting entity and a receiving entity at least partially over a communication network, the transmitting entity comprising:

• means (601, 602) for obtaining a message to be transferred to the receiving entity,
• means (601, 602) for defining a substantially unique identifier at least for one part of the message to be transferred, the substantially unique identifier being defined on the basis of the content of a part of the message,
• means (601, 602) for replacing said part of the message with said substantially unique identifier in a condition that the part of the message is previously transferred to the receiving entity, and
• means (601, 602) for forwarding the message for transfer to the receiving entity.

A system comprising a transmitting entity and a receiving entity, said system being adapted to transmit messages between the transmitting and receiving entities at least partially over a communication network,

• the transmitting entity comprising:
• means for obtaining a message to be transferred to the receiving entity,
• means for defining a substantially unique identifier at least for one part of the message to be transferred, a definition of the substantially unique identifier being based on the content of a part of the message,
• means for replacing said part of the message with said substantially unique identifier in a condition that the part of the message is previously transferred to the receiving entity, and
• means for forwarding the message for transfer to the receiving entity, and
• the receiving entity comprising:
• means for receiving a message transferred from the transmitting entity, the message comprising the substantially unique identifier as a substitute of the part of the message, and
• means for retrieving said part of the message on the basis of said substantially unique identifier.

A computer program for a transmitting entity, the computer program providing a routine for processing messages to be transferred between the transmitting entity and a receiving entity at least partially over a communication network, the computer program controlling the transmitting entity

• to obtain a message to be transferred to the receiving entity,
• to define a substantially unique identifier at least for one part of the message to be transferred, a definition of the substantially unique identifier being based on the content of a part of the message,
• to replace said part of the message to be transferred with said substantially unique identifier in a condition that the part of the message is previously transferred to the receiving entity, and
• to forward the message for transfer to the receiving entity.
