TL;DR
Time-Window-Based Efficient Initial Mapping for Software-Defined Networks (TW-EIMSDN), an online VNE framework that separates immediate admission and initial embedding from deferred, gain-thresholded rule rewriting, is presented.
A detailed comparative evaluation of six controller placement strategies like random placement method, degree centrality, latency-aware, hierarchical, k-median, and genetic algorithm using two widely adopted SDN controllers shows that load balancing improves latency in most configurations and consistently enhances thro...
Results show that live-metric adaptive path selection yields large throughput gains where path diversity can be exploited and behaves as a safe drop-in replacement for shortest-path forwarding otherwise.
A proactive congestion control algorithm based on a bucket-sort approach that groups packets that share the same destination network Internet Protocol (IP) address into a single bucket and transmits them as one packet is proposed.
The lack of determinism restricts the integration of safety-critical applications into Edge–Fog–Cloud (EFC) architectures. Existing EFC schedulers are typically designed for dynamic, best-effort operation based on unmanaged resource allocation and elastic virtualization. This paradigm introduces unbounded queueing, res...
This paper proposes SDN-based traffic engineering approach that combines in one control-plane link utilization monitoring, delay-aware path selection and proactive failure recovery, and proposes a greedy congestion and latency aware routing algorithm and a mechanism of pre-computation of backup paths.
Service Function Chains (SFCs) in Network Function Virtualization (NFV) and Software Defined Networking (SDN) environments must satisfy end-to-end Service Level Agreements (SLAs) while surviving link failures. Existing protection mechanisms either provision redundant Virtual Network Functions (VNFs), incurring addition...
