DYNAMIC CREATION OF VIRTUALIZED NETWORK TOPOLOGY

摘要

For providing resources from a physical network, provided by at least one physical network provider, to a virtual network provider, the following steps are performed: a) identifying a need for certain resources at the virtual network provider (S1); b) requesting resources from the at least one physical network provider (S2); c) conducting virtualization for creating the virtual network by (S3) : c1) identifying and selecting by the at least one physical network provider resources in the physical network (S3); c2) isolating the selected resources from other resources of the physical network and reserving them for exclusive use in the virtual network (S3); and c3) attaching unique identification, address and access information to the isolated and reserved resources in order to enable exclusive accessibility in the virtual network (S3); d) reporting, from the physical network provider to the virtual network provider, a result of the virtualization with information concerning identification, addressability and accessibility of the selected resources (S4); and e) handing over control, from the physical network provider to the virtual network provider, of the resources reserved (S5).
