“…The NGN devices transmit packets over the network initially predetermined for voice transmission, but now the Carrier Ethernet encapsulates all TDM services in its frames. Of course, the price for this is solving synchronization problems and clock distribution, as well enabling appropriate quality of service (QoS) for TDM services transversing through Ethernet networks, which adds another degree of freedom or uncertainty in this regard [8].…”

Microwave line-of-sight radio relay (RR) systems are a constitutive part of a telecom operator transport network, as an alternative to optical transmission systems when the latter are not technically possible or rational to implement. Nowadays, RR links are quite often used in the access network for connecting mobile radio base stations, thus also enabling traffic aggregation, and so on. In this paper, we focus on a practical, real-life, five-section heterogeneous RR network, comprising classic synchronous digital hierarchy (SDH) and SDH new generation network (NGN) architecture, hybrid parallel and mutually independent transmission of native Ethernet and TDM services, and all-IP network parts. Specifically, the main task of this work is to answer whether such a diverse RR system could satisfy the quality norms for Ethernet-based services, meaning whether a tolerable RR unavailability will necessarily imply the according Ethernet quality of service (QoS) degradation. This question is addressed by the comprehensive in-service and out-of-service testing of an operational hybrid RR transmission system. After extensive practical testing and appropriate analysis of the achieved results, it came out that the impact of RR-level impairments that determine the performance prediction affected the Ethernet QoS to the extent that BER values increased to the acceptability threshold values. We believe that the preliminary results reported here could serve as a hint and a framework for a more comprehensive cross-layer test strategy in terms of both test diversity and repeating rate, which contemporary network operators need to implement in order to enable the appropriate quality of experience for users of their services.

“…The migration to NGN has shown to be an evolutionary rather than a revolutionary transition, which has generated a significant impact on the signaling [3]. As signaling is a starting point of the network's evolution, this section reviews its origins and purpose along with the transmission requirements.…”

“…The appropriate signaling and session control layer need to be implemented in the NGN to offer highly available signaling with the reliability and scalability of SS7 network. These requirements present an opportunity to introduce IP Multimedia Subsystem (IMS) technology in the NGN requiring the interoperability and integration of different technologies and protocols as the networks evolve [3].…”

Next Generation Network (NGN) faces the challenge of the rapidly increasing amount of signaling. The growing amount of signaling is a consequence of several reasons arising from the fact that signaling is the main source of network intelligence, analysis, and user behavior monitoring. With the increase in signaling load and complexity, the network management becomes a challenging issue that can impact overall Quality of Service (QoS). To confront this issue, there is a need for reliable and forehand signaling transmission in NGN. As there is much confusion about the interpretation of this concept, this paper aims to provide an overview of the evolution of signaling transmission. Migration towards NGN is analyzed from the signaling perspective. The NGN signaling protocols and related transmission requirements are identified. Through the discussion of standard approaches, the paper considers our previously published approach to signaling transmission along with the current issues and emerging opportunities.

Abstract. Today, service providers need to develop competitive applications for a quick time-to-market to attract and retain end users. To facilitate the task of developers, we introduce a reference Service Creation Environment based on service component and self-management mechanisms. This environment uses a fairly high integration level using meta-modeling techniques and exchange formats: Meta-Object Facility (MOF), Extensible Markup Language (XML), OVF ++ (Open Virtualization Format). Our approach allows developers to design the basic service components based on Quality of Service (QoS), to build the service by composition, and to manage a mobile session by ubiquitous services and the Virtual Service Community.
