The next-generation Ethernet passive optical network (NG-EPON) is basically classified into two architectures on the basis of the wavelength sharing by the optical network units (ONUs). The single scheduling domain (SSD) and multi-scheduling domain (MSD) EPON are the two different design architectures for NG-EPON. A vital task in NG-EPON is to design dynamic wavelength bandwidth allocation (DWBA) algorithms that can meet the future demands of the network subscribers. A number of DWBA algorithms have been designed for time and wavelength division multiplex (TWDM) EPON. The existing DWBA algorithms for TWDM-EPON could be used in MSD-EPON by making necessary parametric changes. The design and implementation of new DWBA algorithms for MSD-EPON are still required specifically. In this paper, we have proposed a quality of service (QoS)-based DWBA algorithm for NG-EPON. We have comparatively analyzed our proposed DWBA with the existing algorithms like earlier finished time (EFT), weighted bipartite matching (WBM), and earlier finished time with void filling (EFT-VF). The results show that our proposed DWBA algorithm performs better as compared to EFT, WBM, and EFT-VF on the basis of average packet delay and average completion time for NG-EPON.

“…In terms of the optical backbone network and metropolitan area network (MAN), one main reason for the congestions is the massive duplicate data transmission requested by different users. Recently, several algorithms and protocols have focused on the issues of optical network congestion 2 and resource utilization efficiency. 3 However, to the best of our knowledge, the investigation of the congestion problem caused by the duplicate service has not been reported in the literature.…”

In this article, a new optical network structure coping with network congestion is proposed, which is based on passive optical network, and adopts data storage devices coupled with optical line terminal to release network burden. It is shown by our network performance simulation that this network has many merits such as free-scale, fewer connections, larger clustering coefficient, and smaller average shortest path length in comparison to the passive optical network. The novel network structure can replace the far-end service connections with the near-end ones, reduce congestions in an optical network, and, furthermore, relieve traffic burden in optical backbone and metropolitan area networks.

“…Statistical algorithms are available for random upstream wavelengths assignment, to control multiband ONUs' lasers [2], [6], [8]. To eliminate spectral overlapping of ONUs' neighboring wavelengths, tunable lasers are used with reduced spectral widths [9]. Thermally stabilized lasers and wavelengths spectral separation of telecommunication channels (TChs) are also used [10].…”

The telecommunications data transfer in singlemode (SM) optical fiber (OF) of a passive optical network (PON) is managed by dynamic bandwidth allocation (DBA). In most internet of things (IoT) sensor network applications, both raw sensing signals and telecommunication data are transmitted in SM OFs, too. At the present time, this is not done in a shared SM OF. This paper presents a novel concept to share FBG sensing and telecommunication services (TS) in the optical C-band of the shared transmission. This concept is based on statistical detection and monitoring of fiber Bragg gratings (FBGs) sensing signals. The key steps of the proposed concept are FBG power spectral peaks statistical detection, monitoring of the FBGs dynamics and periodical estimation of TChs occupancy and availability. The proposed concept was demonstrated and validated using sensor network with a deployed group of FBG-based sensors, by implementing various static or dynamic approaches. By doing so, we achieved telecommunication channels (TChs) bandwidth availability approaching 80 %, compared to previously wasted bandwidth with availability at most 15.6 %. Experimental results showed that a DBA system with implemented dynamic TChs occupancy is a reliable way to share fiber bandwidth between both FBG sensing and TChs.
