“…Furthermore in EPON, incoming IP datagrams are encapsulated in Ethernet frames according to the IEEE 802.3 standard [20], whereas they are launched as IEEE 802. 16 PDUs in the case of WiMAX [19]. Therefore to enable a unified connection-oriented control from the SS to the OLT, and since WiMAX allows for a finer bandwidth allocation than EPON, we propose to modify the MAC protocol in EPON to support connection-oriented requests from the ONU-BS to the OLT.…”

Abstract-This paper proposes a novel framework, WiMAX-VPON, for realizing layer-2 virtual private networks (VPNs) over the integrated IEEE 802.16 Ethernet Passive Optical Network fiber-wireless technology; which has been lately considered as a promising candidate for next-generation backhaul-access networks. With the proposed framework, layer-2 VPNs support a bundle of service requirements to the respective registered wireless/wired users. These requirements are stipulated in the service level agreement (SLA) and should be fulfilled by a suite of effective bandwidth management solutions. For achieving this, we propose a novel VPN-based admission control (AC) and bandwidth allocation scheme that will provide per-stream quality-of-service (QoS) protection and bandwidth guarantee for real-time flows. The bandwidth allocation is performed via a common medium access control (MAC) protocol working in both the optical and wireless domains. An eventdriven simulation model is implemented to study the effectiveness of the proposed framework. PON (EPON); IEEE 802.16 (WiMAX); QoS; virtual private network (VPN). Index Terms-Ethernet

“…Important examples of wireless routing algorithms for FiWi access networks are the so-called delay-aware routing algorithm (DARA) [7], delay-differentiated routing algorithm (DDRA) [8], capacity-and-delay-aware routing (CaDAR) [9], and risk-and-delay-aware routing (RADAR) algorithm [10]. Recently proposed integrated routing algorithms for path computation across the optical-wireless interface include the so-called availability-aware routing [11], multipath routing [12], and energy-aware routing algorithms [13].…”

Abstract-Current Gigabit-class passive optical networks (PONs) evolve into next-generation PONs, whereby high-speed Gb/s time division multiplexing (TDM) and long-reach wavelength-broadcasting/routing wavelength division multiplexing (WDM) PONs are promising near-term candidates. On the other hand, next-generation wireless local area networks (WLANs) based on frame aggregation techniques will leverage physical-layer enhancements, giving rise to Gigabit-class very high throughput (VHT) WLANs. In this paper, we develop an analytical framework for evaluating the capacity and delay performance of a wide range of routing algorithms in converged fiber-wireless (FiWi) broadband access networks based on different next-generation PONs and a Gigabit-class multiradio multichannel WLAN-mesh front end. Our framework is very flexible and incorporates arbitrary frame size distributions, traffic matrices, optical/wireless propagation delays, data rates, and fiber faults. We verify the accuracy of our probabilistic analysis by means of simulation for the wireless and wireless-optical-wireless operation modes of various FiWi network architectures under peer-to-peer, upstream, uniform, and nonuniform traffic scenarios. The results indicate that our proposed optimized FiWi routing algorithm (OFRA) outperforms minimum (wireless) hop and delay routing in terms of throughput for balanced and unbalanced traffic loads, at the expense of a slightly increased mean delay at small to medium traffic loads.Index Terms-Availability, fiber-wireless (FiWi) access networks, frame aggregation, integrated routing algorithms, next-generation passive optical networks (PONs), very high throughput wireless local area network (VHT WLAN).
