“…Admission control in wired networks has been traditionally used as a way to control traffic congestion and guarantee QoS [6,13].The metrics considered in the decision of whether to accept a new flow into a network are mainly bitrate, delay, packet loss and jitter [2,11]. To the best of our knowledge admission control has never been used as a tool to restrict user entrance in a wired network in order to minimise energy consumption.…”

Admission control in wired networks has been traditionally used as a way to control traffic congestion and guarantee quality of service. Here, we propose an admission control mechanism which aims to keep the power consumption at the lowest possible level by restricting the more energy-demanding users. This work relies on the fact that power consumption of networking devices, and of the network as a whole, is not proportional to the carried traffic, as would be the ideal case [1]. As a result some operating regions may be more efficient than others and "jumps" may arise in power consumption when new traffic is added in the network. The proposed mechanism aims to keep power consumption in the lowest possible power consumption level, hopping to the next level only when necessary.

“…As discussed, in these studies, detailed in [Lima et al(2007a)], aspects such as the tradeoff between service assurance level and network control complexity for a scalable and flexible support of distinct service types and corresponding SLSs, intra and interdomain, are not covered or balanced as a whole. The AC model discussed in this paper is a step forward in achieving a flexible and encompassing solution toward a scalable management of multiservice networks able to deal with the management of multiple intradomain QoS levels and interdomain SLSs simultaneously.…”

The clear trend toward the integration of current and emerging applications and services in the Internet launches new demands on service deployment and management. Distributed service-oriented traffic control mechanisms, operating with minimum impact on network performance, assume a crucial role as regards controlling services quality and network resources transparent and efficiently. In this paper, we describe and specify a lightweight distributed admission control (AC) model based on per-class monitoring feedback for ensuring the quality of distinct service levels in multiclass and multidomain environments. The model design, covering explicit and implicit AC, exhibits relevant properties which allow managing QoS and SLSs in multiservice IP networks in a flexible and scalable manner. These properties, stemming from the way service-dependent AC and on-line service performance monitoring are proposed and articulated in the model's architecture and operation, allow a self-adaptive service and resource management, while abstracting from network core complexity and heterogeneity. A proof-of-concept is provided to illustrate the AC criteria ability in satisfying multiple service class commitments efficiently. The obtained results show that the self-adaptive behavior inherent to on-line measurement-based service management, combined with the established AC rules, is effective in controlling each class QoS and SLS commitments consistently.

“…There have been many proposals of AC schemes for the Internet [5,6]. The starting point was a classical hop-by-hop scheme with per-flow signaling and state in nodes, an approach that raised scalability concerns.…”

Admission Control (AC) is an efficient way of dealing with congestion situations in a network. Using AC, when network resources in a path are not enough for all flows (i.e., during congestion), some of the flows receive the requested service and the rest do not. Congestion situations can be reduced by increasing network resources or by optimizing their use through better routing techniques, but if congestion still occurs, AC achieves efficient use of network resources by maximizing the number of satisfied flows. However, using AC complicates the network scheme, and therefore a major concern is making the AC as simple as possible. In this paper we review the main AC schemes that have been proposed for the Internet, focusing on the simplicity of their architectures in terms of the number of nodes that participate in the AC, the required state, the use of signaling, and others.
