摘要: Virtual network embedding which maps the virtual networks to a substrate is important for problems in virtualization. The conventional mapping methods only provide exclusive service that allocates whole bandwidth with full availability requests. This kind of not flexible enough serve variety demands. With these observations, this paper has proposed analyze application careful overbooking concept uses levels Service Level Agreements (SLA) users. Based on framework, subscribers are provided most suitable their tolerability utilize soft-guaranteed bandwidths. helps save cost and increase profitability provider. Furthermore, route resultant traffics through network, we have applied Mixed-Integer Programming formulation minimize cost. reported numerical results demonstrate our method significantly reduces operating while guaranteeing required carefully overbooked quality service.
