A method of establishing proper addressing in a first node so that transport-level communication may be established across a network between a source transport User in said first node and a destination transport User in a second node, said source transport User having a first address and a first addressing format and being supported by a plurality of source transport Providers in said first node at the interface to the network, said destination transport User having a second address and a second addressing format and being supported by a plurality of destination transport Providers in said second node at the interface to the network, each of said source and destination transport Providers having unique address from each other and from said transport Users and an addressing format different from said transport Users, said method comprising the steps of:

  • (a) in said first node, identifying a source transport User requesting to establish communication with a destination transport User;

    (b) in said first node, identifying said requested destination transport User;

    (c) in said first node, identifying one or more of said plurality of source transport Providers, in said first node, which support said source transport User;

    (d) identifying one or more of said plurality of destination transport Providers, in said second node, which support said destination transport User; and
