A method of managing a virtual network, VN, comprising a plurality of VN members comprises associating (710) one or more of the VN members with a first group, the first group including VN members requiring dedicated resource allocations for their corresponding network tunnels, and associating (720) others of the VN members with a second group, the second group comprising VN members that may share resource allocations with other VN members of the second group. Paths are assigned (730, 740) through the one or more physical network domains for the VN members such that the assigned paths for the VN members of the first group provide dedicated resource allocations to each VN member of the first group and such that at least one pair of VN members of the second group traversing a common physical link share a bandwidth allocation for the common physical link.
