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.

Generation Network

The next generation wireless network needs to provide seamless roaming among various access technologies in a heterogeneous environment. In allowing users to access any system at anytime and anywhere, the performance of mobility-enabled protocols is important. While Mobile IPv6 is generally used to support macro-mobility, integrating Mobile IPv6 with Session Initiation Protocol (SIP) to support IP traffic will lead to improved mobility performance. Advanced resource management techniques will ensure Quality of Service (QoS) during real-time mobility within the Next Generation Network (NGN) platform. The techniques may use a QoS Manager to allow end-to-end coordination and adaptation of Quality of Service. The function of the QoS Manager also includes dynamic allocation of resources during handover. Heterogeneous networks raise many challenges in security. A security entity can be configured within the QoS Manager to allow authentication and to maintain trust relationships in order to minimize threats during system handover. The next generation network needs to meet the above requirements of mobility, QoS, and security.

La Red

La provisión de Calidad de Servicio (QoS, Quality of Service) es uno de los aspectos más importantes en el desarrollo de la Red de Nueva Generación (NGN, Next Generation Network). En este sentido, el suministro de QoS en redes basadas en IP, requiere de un proceso de negociación en el que se deben identificar los protocolos e interfaces necesarias para establecer de forma clara los procedimientos a ejecutar entre los elementos y funciones involucrados. Este artículo describe el proceso de negociación de calidad del servicio en el contexto de la NGN, donde el usuario, la capa de transporte y la capa de servicio acuerdan los parámetros de QoS de la sesión que se va a establecer para lograr un servicio con calidad.

In this chapter, the authors present some of the latest developments related to the provisioning of Quality of Service (QoS) in today’s networks and the associated network management structures that are or will be deployed to support them. They first give a brief overview of the most important Quality of Service proposals in the areas of Layer 2 (L2) and Layer 3 (L3) QoS provisioning in backbone networks, and they discuss the network management structures and brokers that have been proposed in order to implement these services. As a case study, they describe the pan-european research and academic network, which is supported centrally by GEANT and which encompasses multiple independent NRENs (National Research and Education Networks). In the last few years, GEANT has developed and deployed a number of production and pilot services meant for the delivery of quality network services to the end users across Europe.

Ensuring high quality of service (QoS) of multicast video stream over next generation network is a challenging issue, and how to implement the wire-speed multicast with hardware logical support in the network nodes of every hierarchy is a key solution to achieve high QoS multicast. Currently, the multicast packets are processed in this way, in which they are copied and then scheduled by ports, lastly, sent respectively. But this approach cannot ensure high QoS in real-time applications. Moreover, the traditional hardware solutions do not possess excellent large-scale scalability owning to their own bottlenecks. In this project, we have constructed a wire-speed multicast switching structure based on Multipath Self-routing Switching Structure, and implemented it on a Stratix IV FPGA chip. Additionally, we have designed the signaling system and control mechanism to support the process of self-routing and wire-speed fan-out copy of multicast packets.
