“…1(c), four requests are served with two LTs, occupying two wavelengths rather than four wavelengths (one wavelength for each request) thanks to joint utilization of FMT and LT. Note that LT operation is achieved in traditional works by using Time Division Multiplexing [4], while in our study we achieve the same result by using MGDM. LT and MGDM naturally fit together as MGs with different reaches can be used to map different requests over the same LT, and these requests can join/leave the LT at intermediate nodes.…”

“…Benefits of MGDM are manyfold: i) MGDM requires only partial MIMO, as only the degenerate modes inside the same MG are processed together at the receiver; ii) MGDM not only provides higher bandwidths, but it also supports sub-wavelength communication capabilities [4], which are currently in high demand, e.g., for 5G/6G backhaul applications [4]; iii) thanks to its ability to multiplex several MGs, MGDM naturally fits for deployment within light trails (LTs) [4], by considering that different MGs could be added/dropped at different intermediate nodes along a single light trail (see Fig. 1(c) and next section for further details on LT).…”

Modern communication systems are probable to surface new challenges while introducing innovative fronts concerning context consciousness in wireless networks. The main outcome behind this expected technological jump will be a whole novel set of intuiting aptitudes forecasted for Fifth Generation (5G) enabled devices. In line with 5G, Software De ned Networking (SDN) is also rising as an intrinsically novel phenomenon.SDN is an unconventional methodology and key technology in modern communication. SDN maintains favorable novelty about network programmability, where network administration is permitted with extraordinary intellections. SDN architecture has the prospective to allow, simplify or augment security implementations in network through instantly reprogrammable centralized view of the data plane. In the near future, 5G and SDN will ripe mobile communication through the development of state-of-the-art implementations such as a smart city, advanced military security, modern national defense, intelligent tra c, etc.; thereby, these emerging mobile communication concepts invoke various signi cant topics, where security is a paramount implication. Therefore, we initiate our focus from basic architecture of 5G and SDN. Next, we analyze security requirements, solutions and challenges in joint paradigm of 5G and SDN. Further, considering the modern communication technological shift, we discuss future trends and research directions in the joint era of 5G and SDN technologies. IntroductionThe unremitting growth in the capacity and aspects of data apprehended by technological advancements has shaped diversi ed ow of data in either organized or unorganized format such as the rise of social media, Internet of Things (IoTs) for Healthcare [1] and huge multimedia communications. Indeed, the rapid expansion of the Internet industry is considerably dependent on communication system speed, which has emerged as a critical steering factor for the advancement in computer networks [2]. Scienti c advancements are rapidly changing the information technology; thereby computer networks are expanding towards incorporation, dissemination, modi cation and intelligence [3]. The pillar behind this anticipated technological hop will be an entire novel set of aptitudes forecasted for Fifth Generation (5G) communication [4]. 5G is encapsulating all advanced emerging technologies like Arti cial Intelligence (AI) [5]. Within the near future, 5G will reap portable communication organized through the advancement of inventive executions such as smart city, smart grid system, advanced military security etc. So, it is considered fundamental to boost the organized engineering of 5G technology. Likewise, Software De ned Networking (SDN) technology is expanding eminently everywhere globally due to its programmable [6], economical, agile, robust and consolidated networking. 5G is more complex and harder to manage as compared to conventional computer telecommunications and satellite communication systems. SDN is a potential organized design that abridge...

“…Lin and Zhuang [29] considered a problem of dynamic multicast traffic grooming problem in light-trail-based WDM networks and proposed efficient algorithms and compare with existing ones. Sharma et al [30] introduced the light-trail as a 5 G backhaul solution for the benefit of dynamic provisioning, optical multicasting and sub-wavelength grooming. In our earlier work, we compared the transmitter and spectrum usage of the five methods of using lightpaths, a single light-tree, multiple light-trees, a single light-trail, and multiple light-trails for establishing a single multicast in EONs [3].…”

Optical multicasting has been considered resource efficient for multicast services. Light-tree and light-trail are two technologies that support optical multicasting while the former requires many splitters and thus experiences significant power loss. In this paper, we consider using the light-trail technology for the accommodation of multicast requests in elastic optical networks with adaptive modulation. For better spectrum efficiency, we consider accommodating each multicast by multiple light-trails. We formulate the problem by Mixed Integer Linear Programming (MILP) and propose efficient heuristic algorithms. For the impact of accommodation sequence on the algorithm performance, apart from the traditional sequence among different requests, we consider an additional sequence among the destinations of a multicast. For efficient multicast accommodation, we propose several strategies and compare their performances through a range of cases. To avoid a destination occupying excessive resources in certain cases of joining multiple light-trails, we propose an efficient algorithm to delete some duplicated destinations. Numerical results show that the proposed heuristic algorithms significantly outperform a benchmark algorithm and one performs close to the optimal MILP. Also, the algorithm for deleting certain destination replicas largely reduces the spectrum and transmitter usages, up to 41% and 20% for the cases considered, respectively.
