A novel dynamic programming inspired algorithm for embedding of virtual networks in future networks

Evaluating the impact of delay constraints in network services for intelligent network slicing based on SKM model

“…As shown in (1), the resource allocation problem is aimed at maximizing the utilization (U(T )). U(T ) is the utilization of the links across the network in each time window T [28]. The link resource utilization relates to the ratio of the used link resources to the link capacity averaged over all substrate links.…”

Novel NFV Aware Network Service for Intelligent Network Slicing Based on Squatting-Kicking Model

“…The performance of our service deployment policy is compared with the chosen state-of-the-art policies with regards to several performance metrics including the total acceptance ratio (AR) and the overall utilization (U), among others. These are commonly used metrics in the literature for assessing the performance of the resource allocation algorithms [46], [47]. All the performance metrics used are described below for each one of the behaviors.…”

“…This parameter considers the average utilization of the links throughout the entire simulation window. The link resource utilization as defined in [47] is the ratio of the used resources to the link capacity averaged over all substrate links. The mathematical formulation of these parameters is given in Eq.…”

“…Mathematically, the average load balancing performance, LB(L)(T) across the links of the full network is given in Eq. ( 32) [47].…”

A deep reinforcement learning-based algorithm for reliability-aware multi-domain service deployment in smart ecosystems

“…This limits the service delivery of those networks and inhibits the infrastructure providers from optimally using the network resources in a dynamic manner [3], [4], [5]. In this regard, network virtualization has emerged as a promising technique to overcome this barrier by enabling the softwarisation of network functions [6], [7], [8]. As a result, services are instantiated as service chains consisting of an ordered set of Virtual Network Functions (VNFs) commonly referred to as Service Function Chains (SFCs), that can be dynamically deployed and scaled according to the real-time requirements [9], [10], [11], [4].…”
