Network virtualization is viewed as a promising approach to facilitate the sharing of physical infrastructure among different kinds of users and applications. In this letter, we propose a topological consistencybased virtual network embedding (TC-VNE) over elastic optical networks (EONs). Based on the concept of topological consistency, we propose a new node ranking approach, named Sum-N-Rank, which contributes to the reduction of optical path length between preferred substrate nodes. In the simulation results, we found our work contributes to improve spectral efficiency and balance link load simultaneously without deteriorating blocking probability.

“…This new generation of optical networks is usually referred to as elastic optical networks (EONs) [22]. R.Yang et al proposed a VONE method that considered the load jointly with the continuity and contiguity constraints through the embedding process in an EON infrastructure [23]. Despite the good results obtained for embedding VN over EON, it did not take the latency constraint in consideration.…”

“…The latency constraint was applied on the virtual links for each VON. Our model used a modified version of the load-balance factor in [23], after adding the latency effect of the EON parts. This factor was inserted through the embedding algorithm such that a comparison was made between conventional results (without latency) and that obtained with latency cases.…”

Nowadays, latency factor in network virtualization takes a serious attention in 5G networks upgrading. Flexgrid/elastic optical network (EON) virtualization recently become known as the fifth-generation (5G) enabling technology for the optical network slicing efficiency. As a consequence, the solution of the virtual optical network embedding (VONE) problem over EON must be solved with the latency targets guarantee. In this work, a new loading factor was suggested after adding the latency effect to the existing EON constraints by identifying its contributing factors in the network. Then, a virtual network mapping algorithm was presented to solve the VONE problem including latency constraint. Network topologies (NSFNET, USNET) were used under the dynamic scenario and four optimization methods which are; alignment and consecutiveness-aware virtual network embedding (ACT-VNE), the local resource capacity and the shortest path first fit (LRC-SP-FF), greedy algorithm and the shortest path first fit (Greedy-SP-FF), load and resource-aware based on ant colony optimization (LRA-ACO) were used and results have been compared to get the optimal solution. The blocking probability on average was increased by approximately 50 % in both topologies affected by adding latency (between 20-50 ms) as compared to the non-latency cases of previous works. Also, during all simulations, the LRA-ACO gave the best embedding performance.

“…The impact of the choice of a packet transfer mode on network performance is analyzed in [17], and to find out how a network node can exploit the wavelength resource to achieve statistical multiplexing efficiency. A heuristic network mapping algorithm called resource and load aware algorithm based on ant colony optimization (RL-ACO) is proposed in [18]. RL-ACO considers the load jointly with spectrum continuity and spectrum contiguity during the node mapping stage and focuses on decreasing the blocking ratio of virtual network requests.…”

Interconnecting networks adopting Fast Optical Switches (FOS) can achieve high bandwidth, low latency, and low power consumption. We propose and demonstrate a novel interconnecting topology based on FOS (FOSquare) with distributed fast flow control which is suitable for HPC infrastructures. We also present an Optimized Mapping (OPM) algorithm that maps the most communication-related processes inside a rack. We numerically investigate and compare the network performance of FOSquare with Leaf-Spine under real traffic traces collected by running multiple applications (CG, MG, MILC, and MINI_MD) in an HPC infrastructure. The numerical results show that the FOSquare can reduce >10% latency with respect to Leaf-Spine under the scenario of 16 available cores.
