In a call and connection separated network, a method of providing distribution of resources of a physical network among different logical networks which are using the physical network for establishing connections. All of the physical resources of the physical network are mapped onto a single logical network description that will comprise nodes, trunk groups interconnecting the nodes, and resource pools. The different logical networks are created by routing tables located at each of the nodes. The routing tables are provided with a fixed maximum percentage figure relating to the maximum amount by which an individual logical network is allowed to use a common resource thus distributing the resources between the different logical networks. By assigning an individual maximum percentage figure to each of the logical networks and in so doing observing the sum of the maximum percentages for all logical networks, it is possible to create complete resource separation of the resource or competition for the resource among the logical networks.
