“…In the beginning, when QPP was conceptualized [6-11, 14, 15, 30, 31], no special care was maintained for the energy consumption during data transmission. Nowadays, without the consideration of energy [26], any one cannot afford transmission [27,28,32]. In addition to this, the bar on usage of energy resources put a constraint for data transmission [33][34][35][36][37][38][39].…”

This paper involved the computation of quickest paths with the help of service-level agreement (SLA) and energy constraints. The consideration of these constraints helps to propose a novel system model which computes the path to strengthen the continuity and criticality of the data transmission. The proposed risk-energy aware SLA provisioning (RESP) system model incorporates the research gaps of the existing risk assessment models in the literature without any increase in time complexity. The formulation of RESP shows the usefulness in the critical applications. The results show that the computation of risk-provisioned path gives the SLA satisfied paths and has a great impact of variations in the data traffic. The performance of the proposed algorithm has been indicated in terms of different performance parameters such as mean s−t paths, average hop counts, and average energy efficiency. Simulation result implies that as data traffic increases, the number of the risk‐provisioned s−t paths decreases whereas corresponding average hop counts and average energy efficiency increases.

“…The authors in [27] present a fault-tolerant job scheduling approach for grid environments using adaptive task replication, which is a recovery approach. Providing resiliency in optical WDM networks through shared path protection has been proposed in [28,29,30,31]. Since meeting strict deadlines and QoS requirements is of great importance in our approach, using protection mechanisms tends to be more reliable.…”

Media production networks require an ecient collaboration between geographically distributed actors and oer predictable workloads, making it possible to exploit this predictability and use advance bandwidth reservation services to achieve greater bandwidth utilization and service guarantees. To oer reliable reservations, the incorporation of fault-tolerance related features in bandwidth reservation strategies is a necessity, although this imposes a waste of capacity and extra performance overhead. As a rst provisional stage to oer a robust reservation system, deploying protection mechanisms ensures that the reservations remain valid when the system is in operation. To maximally utilize the network, and to ensure there is a quick response in a dynamic network environment, constant monitoring and optimization is needed. In this article, we propose an ecient dual optimization approach consisting of two consecutive processes. First, a schedule is produced by a resilient advance reservation algorithm. Then, the generated schedule is continually updated over time using a runtime adaptation approach in order to be capable of dynamically adapting the network to changing conditions and mitigating the side eects of provisioned reliability. This step uses the interconnecting network links' leftover capacity, resulting in an increased performance both in steady and unsteady network conditions. Our evaluations show that in failure-prone environments, the proposed approach leads to signicant increase in the success rate of admitted requests, up to 6.77 times, compared to the resilient advance reservation algorithms.

“…In resilient networks, the basic approach is risk mitigation that involves decrease of the impact. In practice, mitigation uses combination of resilience procedures [5]. In this case, response deployment embraces the configuration of resources and testing.…”

“…Secondly, businesses may be more interested in the variability of loss rather than its mean value, which does not usually capture changes in network behaviour. Here, we use our previous works on the shift of interest in resilient networks design [5][6][7] as a basis. There, we discuss using business-related risk measures, such as Value-at-Risk (VaR).…”

The paper discusses business impact analysis in the context of resilient communication networks. It is based on the total (aggregated) penalty that may be paid by an operator when the services (identified with transport demands) provided are interrupted due to network failures. The level of penalty is expressed as a commonly accepted business risk measure, Value-at-Risk (VaR). First, the main concern over VaR, namely the theoretical lack of subadditivity, is discussed. The study shows that, in practice, disadvantages do not appear in resilient network design, and VaR can be used without the need to apply more complex and less informative measures. Second, a method for calculating the upper bound of the total penalty is presented. The assessment is performed for unprotected and protected services with a broad variety of compensation policies used to translate technical loss to monetarily expressed penalty. The proposed bounds are experimentally shown to be effective in comparison with alternative calculation methods, and also in the case when some of the assumptions taken during the modelling stage are not met.
