Abstract EN
The Network Function Virtualization (NFV) technology aims at virtualizing the network service with the execution of the single service components in Virtual Machines activated on Commercial-off-the-shelf (COTS) servers.
Any service is represented by the Service Function Chain (SFC) that is a set of VNFs to be executed according to a given order.
The running of VNFs needs the instantiation of VNF instances (VNFI) that in general are software components executed on Virtual Machines.
In this paper we cope with the routing and resource dimensioning problem in NFV architectures.
We formulate the optimization problem and due to its NP-hard complexity, heuristics are proposed for both cases of offline and online traffic demand.
We show how the heuristics works correctly by guaranteeing a uniform occupancy of the server processing capacity and the network link bandwidth.
A consolidation algorithm for the power consumption minimization is also proposed.
The application of the consolidation algorithm allows for a high power consumption saving that however is to be paid with an increase in SFC blocking probability.
