QoS enabled resource allocation over an UPnP-QoS — GMPLS controlled edge

This paper focuses on the problem of coherent resource allocation within home and access networks. The interdomain QoS signaling discussed here enables the initiation of the QoS provisioning in the home and access from the end device in users home. The home network considered in this paper is UPnP-QoS enabled while the access network is GMPLS based. We propose and implement an interface between aforementioned network segments allowing for end-to-end QoS establishment. We present the QoS parameters and mechanisms in both UPnP-QoS and GMPLS and how they can be matched to create a coherent QoS architecture. Additionally we investigate the complexity of such a solution and present implementation results.

Next Generation Network based Carrier Ethernet test bed for IPTV traffic

This paper presents a Carrier Ethernet (CE) test bed based on the Next Generation Network (NGN) framework. After the concept of CE carried out by Metro Ethernet Forum (MEF), the carrier-grade Ethernet are obtaining more and more interests and being investigated as the low cost and high performance services of transport network to carry the IPTV traffic. This test bed is approaching to support the research on providing a high performance carrier-grade Ethernet transport network for IPTV traffic.

Bandwidth reservations in home networks: Performance assessment of UPnP-QoS V3

In order for service providers to provide their users high quality services in the home network, Quality of Service (QoS) provisioning is needed to protect premium services. In this paper, we describe how a Universal Plug-and-Play (UPnP) based home network architecture solves this problem in a heterogeneous home network. We outline how it both relieves the end user from troublesome configuration and still offers control to the service provider. We particularly present performance assessment results for UPnP-QoS v3, based on a fully operational experimental implementation. The quantitative measurement results are further used in extensive simulations demonstrating acceptable response times and clear QoS admission differentiation.

UPnP QoS and queuing in home networks

The QoS provisioning in home networks is being more often considered for future use cases, where multiple high bandwidth flows are accommodated in the home environment. This paper investigates chosen characteristics of one of the home network control and management protocol suites, namely UPnP. Using network modeling tools, we evaluate UPnP QoS Architecture and its resource management influence on the end-to-end packet delay characteristics for different scheduling approaches.

Integration of QoS Provisioning in Home and Access Networks

Approaches for QoS provisioning using UPnP for home networks and GMPLS for access networks are described. A solution for interworking the UPnP and the GMPLS at the residential gateway is proposed.

UPnP QoS Architecture and lightweight preemption algorithms

Providing QoS in home networks seems to be more and more important in triple and quadruple play service scenarios. This paper focuses on the analysis of certain aspects of UPnP QoS Architecture designed to provision QoS in home networks. Basic signaling performance is discussed and preemption algorithms are proposed and evaluated.

Network Based Control Point for UPnP QoS Architecture

Enabling the coexistence of non-UPnP Devices in UPnP QoS Architecture is an important issue that might have a major impact on the deployment and usability of UPnP in future home networks. The work presented here shows potential issues of placing a non-UPnP Device in the network managed by UPnP QoS. We address this issue by extensions to UPnP QoS Architecture that can prevent non-UPnP Devices from degrading the overall QoS level. The obtained results show that deploying Network Based Control Point service with efficient traffic classifier, improves significantly the end-to-end packet delay characteristics.

ALPHA: Proposal of Mapping QoS Parameters between UPnP Home Network and GMPLS Access

This paper is treating the interdomain QoS signaling between the home and access domains with a focus on applying it for providing QoS between a UPnP-QoS based home network and GMPLS based access network. The work presented here is defining a possible approach for an interface between UPnP-QoS and GMPLS in order to move towards end-to-end QoS establishment as well as investigating the complexity of such a solution. We present the QoS parameters and mechanisms in both UPnP-QoS and GMPLS and how they can be matched to create a coherent QoS architecture.

Signaling performance of UPnP QoS Architecture

Provisioning QoS within home networks becomes a common requirement. This paper evaluates one of the candidates for home network control and management protocol suites, namely UPnP. Using network modeling tools we identify highlights and drawbacks of UPnP QoS Architecture.
