Abstract:
1. A method of controlling routing operations in a communication network, wherein said network is associated with an external network and comprises a set of nodes, each of which has associated therewith a primary address for internal communication within said network, said set of nodes comprising terminals and gateways, said gateways being suitable to provide connections between said terminals and said external network, comprising the steps of: sending from the gateways to the terminals first messages containing global prefixes; building for each of said terminals one or more secondary addresses based on said global prefixes, said secondary addresses being independent from said primary addresses and defining valid global internet protocol addresses; generating in each of said terminals a respective second message containing at least a sub-set of the corresponding secondary addresses; and broadcasting the second messages to all the terminals of the set of nodes.
