By providing software-based network function services, network function virtualisation (NFV) has gained a lot of popularity due to its flexible deployment and lower operational/maintenance costs. To realise better results from the NFV, the service function chaining (SFC) requires suitable order-based virtual network functions (VNFs) execution on the virtual machines. The SFC provisioning literary works suffer from higher latency as they rely on non-dedicated resources rather than both dedicated and non-dedicated resources. An effective resource allocation approach for multiple SFC provisioning by considering associated delays, payment, deadlines, time-sensitive, non-sensitive requests, SFC sorting order were out of their investigations. To tackle these issues, this paper yields ownership, latency, and cost-based resource allocation approach for SFC provisioning for NFV-assisted networks by taking different requests, service requirements, and resources, into account. The results validate that the proposed approach achieves up to 54% SFC delay and 47% energy cost gain than the traditional approaches.
