Dynamic Bandwidth

Passive Optical Networks (PONs) are very suitable architectures to face today’s access challenges. This technology shows a very cost saving architecture, it provides a huge amount of bandwidth and efficiently supports Quality of Service (QoS). In PON networks, as all subscribers share the same uplink channel, a medium access control protocol is required to provide a contention method to access the channel. As the performance of Time Division Multiplexing Access (TDMA) protocol is not good enough because traffic nature is heterogeneous, Dynamic Bandwidth Allocation (DBA) algorithms are proposed to overcome the problem. These algorithms are very efficient as they adapt the bandwidth assignment depending on the updated requirements and traffic conditions. Moreover, they should offer QoS by means of both class of service and subscriber differentiation. Long-Reach PONs, which combine the access and the metro network into only one by using 100 km of fibre, is an emergent technology able to reach a large number of far subscribers and to decrease the associated costs.

Large deployments of access points in wireless local area networks (WLANs) based on the IEEE 802.11 standard require management, configuration and control mechanisms. Centralized WLANs are defined as multi-cell wireless access networks that implement some of these functions in a centralized manner. In this chapter the authors illustrate how the mechanisms designed for the management of centralized WLANs can also be used for monitoring parameters related to QoS support and for pursuing QoS goals. They describe the Control and Provisioning Wireless Access Protocol (CAPWAP), a recent IETF standard for the management of centralized WLANs which is currently in the final stages of the definition process, its implementation for the existing types of centralized WLANs, and its use for monitoring and QoS management. The authors discuss the QoS goals that can be pursued in this framework, such as access control, load balancing, cell resizing, and Medium Access Control parameters adaptation, as well as the algorithms and strategies that can be used to fulfill them.
