ABSTRACT:
A method for transferring data, by establishing network links between a private and a public network. Each link is associated with a respective unique public-network-address. Each session of one or more data packets within the private network is allocated an extended-private-address, the private network being adapted to transfer each data packet in a respective session using at least part of the extended-private-address as an identifying private-network-address. For each session the extended-private-address is translated to an extended-public-address, which includes one of the unique public-network-addresses. The data packets of each session are conveyed between the private and public networks via the link associated with the public-network-address of the respective session, and are transmitted within the public network using at least part of the extended-public-address as an identifying public-network-address.
