“…The merits of policies and their architectural integration in the described standardized admission control systems are discussed in [46]. They argue that policies are needed to decouple the configuration of a particular system, tailored to the network provider, from the actual business logic of the system.…”

The important new revenue opportunities that multimedia services offer to network and service providers come with important management challenges. For providers, it is important to control the video quality that is offered and perceived by the user, typically known as the Quality of Experience (QoE). Both admission control and scalable video coding techniques can control the QoE by blocking connections or adapting the video rate but influence each other's performance. In this article, we propose an in-network video rate adaptation mechanism that enables a provider to define a policy on how the video rate adaptation should be performed to maximize the provider's objective (e.g., a maximization of revenue or QoE). We discuss the need for a close interaction of the video rate adaptation algorithm with a measurement based admission control system, allowing to effectively orchestrate both algorithms and timely switch from video rate adaptation to the blocking of connections. We propose two different rate adaptation decision algorithms that calculate which videos need to be adapted: an optimal one in terms of the provider's policy and a heuristic based on the utility of each connection. Through an extensive performance evaluation, we show the impact of both algorithms on the rate adaptation, network utilisation and the stability of the video rate adaptation. We show that both algorithms outperform other configurations with at least 10%. Moreover, we show that the proposed heuristic is about 500 times faster than the optimal algorithm and experiences only a performance drop of approximately 2%, given the investigated video delivery scenario.

“…Standards bodies such as 3GPP, ETSI's TISPAN and IETF have defined a number of policy-based control architectures which can be found in [7][8][9] for example. TISPAN specified a Resource and Admission Control Subsystem (RACS) comprising of a Service-based Policy Decision Function (SPDF) and Access Resource Admission Control Function (A-RACF) [4,8]. Both SPDF and A-RACF interact with Policy Enforcement Points (PEPs) in the underlying transport network.…”

Adaptive Measurement-Based Policy-Driven QoS Management with Fuzzy-Rule-based Resource Allocation

Fixed and wireless networks are increasingly converging towards common connectivity with IP-based core networks. Providing effective end-to-end resource and QoS management in such complex heterogeneous converged network scenarios requires unified, adaptive and scalable solutions to integrate and co-ordinate diverse QoS mechanisms of different access technologies with IP-based QoS. Policy-Based Network Management (PBNM) is one approach that could be employed to address this challenge. Hence, a policy-based framework for end-to-end QoS management in converged networks, CNQF (Converged Networks QoS Management Framework) has been proposed within our project. In this paper, the CNQF architecture, a Java implementation of its prototype and experimental validation of key elements are discussed. We then present a fuzzy-based CNQF resource management approach and study the performance of our implementation with real traffic flows on an experimental testbed. The results demonstrate the efficacy of our resource-adaptive approach for practical PBNM systems

The Third Generation Partnership Project specifies a solution to handle the heterogeneity of future networks, including quality of service (QoS) and charging aspects. This solution utilizes a policy-based approach based on the policy and charging control (PCC) architecture, which is an integral component of the evolved packet system (EPS). The specifications for EPS are being finalized with the evolved packet core (EPC) central to this framework. The EPC is a simplified, flat, all IP-based architecture that supports mobility between heterogeneous access networks and incorporates an evolved QoS concept based on the PCC framework. A critical open issue within EPS is the provisioning of end-to-end QoS enabled paths. This article proposes enhancements to the EPC/PCC framework that extend the end-to-end inter-domain mechanisms to discover the signaling routes at the service control layer, and use this information to determine the paths traversed by the media at the resource control layer. Because the approach operates at these layers, it is compatible with existing transport networks and exploits already existing QoS control mechanisms. A real testbed implementation, comprising free and open source software, is used to evaluate the proposed mechanisms. The obtained results show that the framework has an acceptable effect on session setup delay and core traffic overhead in a range of scenario ranging from simple, to typical, to worst case
