“…Therefore, each partition load is adjusted, and splitting occurs across the number of switches in the controller management domain and the size of the flow to be processed by each switch. As a result, neighboring domain controllers in the sub-networks try to create a destination to change the resource itself and cooperate in a distributed manner to decide the available resources providing the required bandwidth for the allocation process feedback on the network's state [4].…”

“…Our approach would also rely on a regular resource check policy to assure that the allocated network resources are optimal with respect to user mobility patterns, but with the additional objective to minimize OPEX using as fewer switches as possible. Tariq and Bassiouni [41] have proposed an SDN enabled QoS-aware Multipath-TCP (MPTCP) solution based on Dijkstra's algorithm that selects P paths between two end nodes, while Wang et al [42] explore multipath forwarding for scheduling MPCTP flows in a virtualized environment. However, MPTCP splits a flow into sub-flows that are forwarded into multiple paths, which may prove to be impractical for none-TCP flows and complex to handle for mobile users.…”

Software Defined Networking (SDN) is a driving technology for enabling the 5th Generation of mobile communication (5G) systems offering enhanced network management features and softwarization. This paper concentrates on reducing the operating expenditure (OPEX) costs while i) increasing the quality of service (QoS) by leveraging the benefits of queuing and multi-path forwarding in OpenFlow, ii) allowing an operator with an SDN-enabled network to efficiently allocate the network resources considering mobility, and iii) reducing or even eliminating the need for over-provisioning. For achieving these objectives, a QoS aware network configuration and multipath forwarding approach is introduced that efficiently manages the operation of SDN enabled open virtual switches (OVSs). This paper proposes and evaluates three solutions that exploit the strength of QoS aware routing using multiple paths. While the two first solutions provide optimal and approximate optimal configurations, respectively, using linear integer programming optimization, the third one is a heuristic that uses Dijkstra short-path algorithm. The obtained results demonstrate the performance of the proposed solutions in terms of OPEX and execution time.

“…VN embedded problem: In this paper, all the VN requests represent end‐to‐end communications, each virtual link can be mapped to a loop‐free substrate path (single path) or a set of disjoint substrate paths (multi‐paths [31]). We denote the mapping from the virtual link to substrate links is
