This article presents a numerical implementation of the activation process for gigabit and 10 gigabit next generation and Ethernet passive optical networks. The specifications are completely different because GPON, XG-PON and NG-PON2 were developed by the International Telecommunication Union, whereas Ethernet PON was developed by the Institute of Electrical and Electronics Engineers. The speed of an activation process is the most important in a blackout scenario because end optical units have a timer after expiration transmission parameters are discarded. Proper implementation of an activation process is crucial for eliminating inadvisable delay. An OLT chassis is dedicated to several GPON (or other standard) cards. Each card has up to eight or 16 GPON ports. Furthermore, one GPON port can operate with up to 64/128 ONUs. Our results indicate a shorter duration activation process (due to a shorter frame duration) in Ethernet-based PON, but the maximum split ratio is only 1:32 instead of up to 1:64/128 for gigabit PON and newer standards. An optimization improves the reduction time for the GPON activation process with current PLOAM messages and with no changes in the transmission convergence layer. We reduced the activation time from 215 ms to 145 ms for 64 ONUs.

“…15 of 5G New Radio (NR) standard by 3GPP, which refers to the exploitation of spectrum bands up to 52.6 GHz, with Rel. 16 including even higher frequencies [2]. Nevertheless, mmWave bands experience high propagation losses, and therefore, enable shorter link ranges than traditional sub-6GHz networks.…”

“…To this end, the gated service scheme addresses this challenge by allocating transmission windows proportional to the number of packets located at the buffer of each user during the reporting phase. This scheme has received great research attention and has been also studied in the context of the Interleaved Polling with Adaptive Cycle Time (IPACT) protocol for Ethernet Passive Optical Networks (EPONs) [15,16]. As shown in [17], gated service IPACT achieves considerable lower delay compared to fixed-service IPACT.…”

A. Mesodiakaki 1[0000−0001−9309−0524] , P. Maniotis 1 , G.Abstract. Next generation, i.e., fifth generation (5G), networks will leverage both fiber and wireless (FiWi) technology to meet the challenging 5G traffic demands. Moreover, a Cloud-Radio Access Network (C-RAN) architecture will be mainly adopted, which places the BaseBand Units (BBUs) at centralized locations, thus offering cost-efficient energy supply and climate control. To this end, efficient Medium Transparent-Medium Access Control (MT-MAC) protocols are needed to ensure the optimal exploitation of both media. In this paper, we propose a gated service MT-MAC protocol (gMT-MAC) for Millimeter Wave (mmWave) Analog Radio-over-Fiber (A-RoF) C-RANs. GMT-MAC grants a transmission window to each user equal to the time needed for its requested traffic to be successfully sent. A mean packet delay model is also proposed and verified by means of simulation. The performance of gMT-MAC is evaluated for different network load conditions, number of Remote Radio Heads (RRHs) and optical availability values. The provided results prove the suitability of gMT-MAC to meet the sub-ms delay requirements of latency-critical 5G services.Keywords: Fifth Generation (5G) networks · mean packet delay model · fiber-wireless (FiWi) · millimeter wave (mmWave) · cloud-radio access networks (C-RANs) · analog radio-over-fiber (A-RoF) · medium transparent-MAC (MT-MAC).

“…Nonetheless, neither of the two protocols accounts for service equalization on a per packet-level, since they target fairness among RRHs (fixed-service) or clients per RRH (Client-Weighted) but without considering the amount of traffic generated by every client within every transmission period. The gated service discipline, i.e., granting transmission windows equal to the number of bytes contained in a user's buffer, effectively addresses the aforementioned problem, and has been extensively studied in the literature, primarily in the context of the Interleaved Polling with Adaptive Cycle Time (IPACT) protocol for Ethernet Passive Optical Networks (EPONs) [15], [16], with delay analysis models confirming superior delay performance compared to fixed-service IPACT [17]. However, to the best of our knowledge, a gated service scheme has never been employed in the context of converged A-RoF FiWi networks, and its delay properties have yet to be studied.…”

Fifth Generation (5G) Cloud-Radio Access Networks (C-RANs) are about to exploit both optical and Millimeter Wave (mmWave) technology to meet the ever-increasing traffic demands. In this new type of converged Fiber-Wireless (FiWi) systems efficient Medium Transparent-Medium Access Control (MT-MAC) protocols should be designed, able to satisfy the very strict 5G service requirements. To this end, in this paper, we propose an MT-MAC protocol for mmWave Analog Radio-over-Fiber (A-RoF) C-RANs, which employs gated service, according to which users are granted transmission windows equal to the number of bytes contained in their buffer. An analytical model is also proposed for the mean packet delay, which is verified by means of simulation for different fiber length values, network load conditions and optical capacity values. Our results not only prove the accuracy of the proposed model but also the suitability of the proposed MT-MAC protocol to meet the sub-ms delay challenge of latency-critical 5G network requirements.
