Squatting and kicking model evaluation for prioritized sliced resource management

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

“…Currently, few works, in literature focus on the link resources management (e.g., bandwidth management) considering a multi-slice scenario with prioritized demands despite its necessity for the realization of future network services characterized by massive bandwidth requirements [20], [21], [22]. Regarding bandwidth resource management under a multislice scenario, SKM exhibits competitiveness compared to Bandwidth Allocation Models (BAMs) and best-effort algorithms, especially during congested scenarios [23]. We, therefore, consider the SKM algorithm for this work.…”

“…In this paper, the authors are exploiting the results from their previous work in El-mekkawi et al [23] in the following aspects:…”

“…• Proposing a service deployment algorithm based on the intelligence of the SKM model defined on [23] to maximize the number of successfully allocated service demands while maximizing the utilization and uniformly distributing the traffic across the different links of the network. Moreover, this algorithm can handle service requirements with different strict constraints, in both off-line and on-line modes.…”

“…• Adopting a realistic 5G network environment: the work proposed in [23] was analysed based on scenarios that are not representative of a realistic 5G network environment by considering single link network topology. However, in this work, we have analysed based on a realistic 5G scenario where the network topology is complex, the transmission is real-time, the requests arrive in online mode, and the demand structure is much more complicated compared to the mentioned paper (i.e., the demands are defined by source, destination, bandwidth, priority and lifetime to be allocated along the requested in a given network).…”

“…The traffic prioritization may be enforced by adjusting resource utilization or preempting lower priority traffic [2]. In this regard, in this work, we exploit the kicking technique defined in [23] to ensure E2E high admission for higher priority slices during congested cases.…”
