“…The measurement takes into account the accepted "probe" packets and the "refresh" packets (instead of the "ordinary" packets). Finally, some variations of this scheme were proposed in [31], such as replacing the initial sequence of "probe" (signaling) packets by a single signaling packet carrying the desired resources, using an AC release packet and improving the measurement algorithm.…”

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.

“…If a refresh message corresponding to a number of reserved resource units (i.e., bandwidth) is not received, the aggregated reservation state is decreased in the next refresh period by the corresponding amount of resources that were not refreshed. The refresh period can be refined using a sliding window algorithm described in [RMD3].…”

This document describes a Next Steps in Signaling (NSIS) Quality-ofService (QoS) Model for networks that use the Resource Management in Diffserv (RMD) concept. RMD is a technique for adding admission control and preemption function to Differentiated Services (Diffserv) networks. The RMD QoS Model allows devices external to the RMD network to signal reservation requests to Edge nodes in the RMD network. The RMD Ingress Edge nodes classify the incoming flows into traffic classes and signals resource requests for the corresponding traffic class along the data path to the Egress Edge nodes for each flow. Egress nodes reconstitute the original requests and continue forwarding them along the data path towards the final destination. In addition, RMD defines notification functions to indicate overload situations within the domain to the Edge nodes.

“…This paper presents a new QoS framework, called Resource Management in Differentiated Services (RMD), which aims to correct this situation. RMD is introduced in [13], [14], [15], [16], [17] and [18], and it represents a QoS framework that extends the Diffserv architecture with new admission control and resource reservation concepts in a scalable way. Even though it is optimized for networks with fast and highly dynamic resource reservation requirements, such as IP-based cellular radio access networks [19], it can be applied in any type of Diffserv networks.…”

The flexibility and the wide deployment of IP technologies have driven the development of IP-based solutions for wireless networks, like IPbased Radio Access Networks (RAN). These networks have different characteristics when compared to traditional IP networks, imposing very strict requirements on Quality of Service (QoS) solutions, such as fast dynamic resource reservation, simplicity, scalability, low cost, severe congestion handling and easy implementation. A new QoS framework, called Resource Management in Differentiated Services (RMD), aims to satisfy these requirements. RMD has been introduced in recent publications. It extends the IETF Differentiated Services (Diffserv) architecture with new admission control and resource reservation concepts in a scalable way. This paper gives an overview of the RMD functionality and its performance behavior. Furthermore, it shows that the mean processing delay of RMD signaling reservation messages is more than 1330 times smaller then the mean processing delay of RSVP signaling reservation messages.
