AbstractPassive optical network (PON)-supported orthogonal frequency-division multiplexing is viewed as a capable answer designed for subsequent generation optical networks in terms of traffic coloring when integrated with monarch butterfly optimization (MBO). Traffic coloring optimization (TCO) or MBO algorithmic rule solves the matter of controlling the traffic, began by end-user transceivers with multiple parameters through rescheduling transmission capacity and bandwidth allocation strategy of the optical network, which are done by means of its operator functions. The TCO method with granularity adjustment components outcome signifies an improvement in quality of service as it reduces jitter and increases throughput in PON by 350 µs and 12.5 %, respectively. It even improves the blocking probability and fairness index.

AbstractPassive optical network (PON) supported orthogonal frequency division multiplexing is a network that is designed for subsequent generation of optical networks. During this work, the proposed algorithm consists of neurofuzzy rules which update and control the minimum bandwidth allocation granularity \left( g \right). In order to improve the quality of service, a biogeography-based optimization algorithm is introduced and a new fitness function is proposed which reduces the round trip time by enhancing the distribution scaling factor. Hence, the proposed work reduces the jitter and increases the throughput of the PON for fixed g = 1 which enhances the network performance by 3.4 % and 1.23 %, respectively.

This paper proposes an alternative solution for Long-Reach Ethernet passive optical networks. The proposed scheme enables directly communication between ONUs for the transmission of local traffic and control messages, and each ONU calculates bandwidth allocation independently without participation of OLT to remedy the long propagation delay of LR-PON. This scheme also supports centralized control by OLT to change ONUs’ parameters synchronously. Simulation results show that this scheme can effectively reduce the end-to-end packet delay, while maintaining high throughput in uplink channel.

Abstract Hybrid wavelength division multiplexed (WDM)/Time division multiplexed (TDM) virtual passive optical networks (VPONs) are considered to provide cost efficient solutions for ever increasing bandwidth requirements of next generation optical access networks. With the development in technology effective bandwidth assignment has emerged as a major concern area. In this paper a novel heavy load optimized dynamic bandwidth allocation algorithm (HLO-DBA) is proposed for the hybrid WDM/TDM VPONs. Multi point control protocol of Ethernet passive optical network (EPON) is implemented for WDM/TDM VPONs subscribers. The excess bandwidth of lightly loaded subscribers is distributed among heavily loaded users through an efficient mechanism. The proposed technique effectively utilize the idle period between the last transmitted REPORT messages from previous transmission cycle (t-1) to the first GRANT message in the current cycle (t). Optical network units (ONUs) connecting the subscribers are scheduled in such a way so as to reduce the wastage of bandwidth. Performance evaluation of HLO-DBA in terms of quality of service (QOS) metrics like throughput and average delay is done to validate the optimization of the proposed mechanism.

Dynamic Bandwidth

Bandwidth allocation is one of the critical issues in the design of Ethernet passive optical networks (EPONs). In an EPON system, multiple optical network units (ONUs) share a common upstream transmission channel for data transmission. To efficiently utilize the limited bandwidth of the upstream channel, a system must dynamically allocate the upstream bandwidth among multiple ONUs based on the instantaneous bandwidth demands and quality of service requirements of end users. This chapter gives an introduction of the fundamental concepts on bandwidth allocation in an EPON system, discusses the major challenges in designing a polling protocol for bandwidth allocation, and presents an overview of the state-of-the-art dynamic bandwidth allocation (DBA) algorithms proposed for EPONs.

Passive optical network (PON) is a cost-efficient access network technology to deliver broadband services. Moreover, service providers employ PONs to offer novel services. New business scenarios are, thus, envisioned in which customers owning multiple optical network units (ONUs) are connected to a single PON (multi-ONU customers). This paper proposes a dynamic bandwidth allocation (DBA) algorithm to guaranteed bandwidth for multi-ONU customers in Ethernet PONs (EPONs). It also introduces a bandwidth sharing algorithm to support cooperation among customers. Results show that the proposed algorithm can improve the overall throughput and quality of service provisioning.

Abstract Integration of Ethernet passive optical network (EPON) and WiMAX technologies is viewed as a great solution for next-generation broadband access networks. In the systems adopting this strategy, weighty bandwidth allocation schemes are fundamental to fulfil the quality of service (QoS) and fairness requirements of different traffic classes. Existing proposals to overcome the bandwidth allocation problem in EPON/WiMAX networks dismiss collaboration between the self-interested EPON and WiMAX service providers (WSPs). This study presents a novel EPON-based semi-dynamic bandwidth allocation (S-DBA) method that shows points of interest in the integration process. In the proposed algorithm depending on the auction process, the optical line terminal runs an auction to adequately post the optical network unit bandwidth that distributes the most elevated bidders based on the measurement of the accessible bandwidth. Simulation results demonstrate massive upgrades compared with fair sharing using dual-service-level agreements, ‘limited service’ interleaved polling with adaptive cycle time methods, bandwidth allocation strategy using Stackelberg game, and bandwidth allocation strategy using coalition game regarding the quality of service parameters such as throughput and time delay. This will be extremely helpful for optical system upgrading and improvement with minimal effort.

AbstractThe blocking probability is studied for improving the quality of service of the network. The call blocking model for mode of operation to determine the types of applications suitable for Generalized Multi-Protocol Label Switched (GMPLS) networks is proposed. The performance of optical network depends upon various parameters such as number of channels, number of sources, traffic intensity which directly affect the blocking probability of the network. A mathematical model of an optical network for blocking probability of cleared calls and holding calls is developed. In the proposed model, blocking probability of the network gets reduced with a large number of servers. The proposed models decrease the blocking probability of the network to a level of 10–40. In addition, the blocking performance for held calls is also analyzed to compare the amount of traffic intensity that can be handled and completed properly with that of the cleared calls probability. The blocking probability is less for cleared calls than that for held calls as more traffic intensity can be handled in case of cleared calls but the chances for call completion increases in case of held calls.

With steady traffic volume growth in the core networks, it is predicted that the future optical network communication will be constrained mainly by the power consumption. Hence, for future internet sustainability, it will be a mandate to ensure power-efficiency in the optical networks. Two paradigms known to support both, the traffic heterogeneity and high bandwidth requests are the: (i) next generation flexible (or elastic) orthogonal frequency division multiplexing (OFDM) based networks which provide flexible bandwidth allocation per wavelength, and (ii) currently deployed mixed-line-rate (MLR) based networks which provision the co-existence of 10/40/100 Gbps on varied wavelengths within the same fiber. In this work, the power-efficiency of an OFDM, and a MLR based network has been compared for which, a mixed integer linear program (MILP) model has been formulated considering deterministic traffic between every network source-destination pair. The simulation results show that in regard to power-efficiency, the OFDM based network outperforms the MLR based network.
