We present some issues related to QoS guaranteeing in next generation terabit IP optical networks. We report basics of MPLS/MPLambdaS technologies and some of their functionalities that enable QoS protection environment for IP networks. Application example of MPLS/MPLambdaS in photonic packet switching and wavelength switching to provide QoS is also presented.

We demonstrate for the first time a field trial of 80 (10 x 8) Gbps colored optical packet switching of 4K and 2K uncompressed streaming using SOA based broadcast-and-select switch and optical-code label processing. Introduction “4K” motion pictures (3840x2160 pixels), 4 times pixel counts of high-definition (HD), are promising imaging technology for digital cinema, computer visualization, and...

IP traffic in the core and access networks increases rapidly by the speed-up of the access network and the spread of the rich applications. 10 Gigabit Ethernet (10 GE) becomes a popular link technology to connect IP routers and Ethernet switches not only intra-office transmission links but also inter-office long reach transmission links. The optical layer protection switching is expected to pro...

To cope with the growth in the Internet and corporate IP networks we require IP routers capable of much higher performance than is possible with existing architectures. This paper examines two approaches to the design of a high-performance router, the gigabit router and the IP switch, and then provides some detail on the implementation of an IP switch and the protocols associated with IP switch...

Multicasting has become increasingly important with the emergence of Internet-based applications such IP telephony, audio/video conferencing, distributed databases and software upgrading. IP Multicasting is an efficient way to distribute information from a single source to multiple destinations at different locations. In practice IP is considered as a layer 3 protocol. Multiprotocol label Switc...

IP based networking is seen to take the major role in the ongoing network and service converge process. However, a number of other networking solutions exist and it is anticipated that the future services will be carried to users over a diverse set of networks. This implies the need for interworking between the different network concepts and especially interworking between different signalling ...

In this study the Fast Hinted Cell Switching movement detection method for Mobile IP is introduced. This method assumes that the Link-Layer is capable of delivering information to Mobile IP regarding the identity of the local mobility agent. This tends to negate the need for Mobile IP movement detection as well as agent discovery and leads to accelerated Mobile IP hand-offs. Moreover, the exist...

Monitoring call quality in a Voice over IP (VoIP) environment has great importance to collect information about those calls on the network. Packet loss on the network and de-jitter buffer, delay and subjective speech evaluation using the E-Model will enable the manager to verify the quality of calls. This article proposes the development of an agent to implement objects with statistical data ab...

The aim of this paper is to study the performance of Mobile IP hand-offs. It is determined that the key issue is the movement detection method (i.e. Lazy Cell Switching, Prefix-Matching, Eager Cell Switching). For this paper all three movement detection methods are studied. The study involves single agent subnetworks and simple movement patterns, i.e. straight movement from one subnetwork to an...
