In this paper, the problem of routing, modulation level, core, and spectrum assignment (RMCSA) in space-division-multiplexed elastic optical networks (SDM-EONs) is studied. We formulate as a mixed-integer linear programming (MILP), which dedicated shared path protection schemes are supported SDM-EONs with multi-core fibers (MCFs) inter-core crosstalk MCFs strictly modeled. Furthermore, an efficient heuristic algorithm proposed to solve RMCSA large scale scenario. Numerical results reveal...
As elastic optical networks (EONs) are expected to convey high bitrate connections, a failure in these causes vast data losses. Thus, addressing the problem of survivability EONs is great importance. In this paper, an EON with multiclass traffic investigated, where each type needs specific protection mechanism and scheduling strategy. particular, connection request may demand for dedicated path protection, shared backup or restoration mechanism. Besides, it can tolerate pre-determined delay...
Elastic Optical Network (EON) is a promising solution to address the high capacity, low latency, and flexibility requirements of upcoming 5th-generation (5G) networks. Furthermore, Multi-Core Fibers (MCFs) Space Division Multiplexing (SDM) technique can be utilized overcome capacity limitation conventional Single Mode (SMFs). On other hand, Quantum Key Distribution (QKD) an effective security issues in 5G transport In this paper, we investigate performance QKD over elastic optical networks...
The transmission capacity of traditional single core fibers is reaching its upper bound. Space-division multiplexing (SDM) leveraging multi-core considered to be a promising solution for this problem. Elastic optical networks (EONs) with Multi-core (MCF) are kind SDM-enabled EONs (SDM-EON) providing larger capacity. However, the resource assignment in these becomes more complex due inter-core crosstalk. Another important issue future time domain behavior incoming traffic which means...
