Abstract
Network function virtualization (NFV) decouples network functions from dedicated hardware by implementing them as software-based virtual network functions (VNFs), thereby enabling flexible network resource management. Network services are provisioned through service function chains (SFCs) composed of multiple VNFs. Given SFC requests and physical machines (PMs), this paper investigates the VNF deployment problem with three objectives: maximizing the service acceptance ratio (SAR), minimizing the total energy consumption (TEC), and balancing the load among PMs. We then propose a load-aware and energyefficient VNF deployment (LEEV) scheme that dynamically adapts its deployment strategy based on the system load. Under lightload conditions, LEEV deploys adjacent VNFs of a given SFC on one PM to reduce energy consumption, while under heavy-load conditions, it can shift toward load-balancing deployment without sacrificing energy efficiency. Simulation results reveal that LEEV achieves a higher SAR, lower TEC, and improved load balance.
Space-air-ground integrated networks (SAGINs) offer seamless three-dimensional coverage and strengthened flexibility, which are recognized as a core network architecture of 6G. Software-defined networking (SDN) and network function virtualization (NFV) are two enabling technologies for SAGINs that can be utilized to se...

Impact-Aware Virtual Data Center Embedding with Incremental Analysis for SDN-controlled Networks (IDEAL) is proposed, which estimates the incremental system impact of each tentative VM placement using two criteria: marginal energy increment and incremental load-balance distortion.

As Data Center Networks (DCNs) continue to scale, the limitations of traditional centralized Software-Defined Networking (SDN) architectures become increasingly apparent, as they fail to meet the stringent demands for low latency and quality of service (QoS). In this paper, we propose an adaptive traffic-aware load bal...
The rapid proliferation of IoT devices and ecosystems creates significant challenges in managing increasing data traffic and service requests while maintaining system performance [1]– [3]. In oneM2M-based IoT systems, overloaded Common Service Entities (CSEs) can become bottlenecks, leading to resource saturation, high...
