The technology used in citizen-to-authority emergency calls is based on traditional telephony, that is, circuit-switched systems. However, new standards and protocols are being developed by the Internet Engineering Task Force (IETF) to allow emergency communications over packet switched networks, such as the Internet. This architecture is known as Next Generation-9-1-1 (NG-911). In this paper, ...

In this paper, the Optical Burst Switching with Burst Dropping (OBS/BD) technique is proposed to be implemented in an all-optical backbone network to support IP traffic. The OBS/BD is based on two main features: i) several IP packets are assembled in a single macro-packet, called burst; ii) the burst contention in an optical switch is handled by the means of two techniques: the wavelength dimen...

Congestion avoidance techniques for event builders using switching network technologies is a major issue. Traffic management of the data flow is an essential point to avoid congestion. Global traffic control is one of the mechanisms to manage the traffic. It uses global information of the switching network. While, traffic shaping technique is another mechanism not to use them. Quality of Servic...

One of the major issues in the networking industry today is the tremendous demand for more and more bandwidth. With the development of all-optical networks and the use of Dense Wavelength Division Multiplexing (DWDM) technology, a new and probably very crucial milestone is being reached in network evolution. In this scenario, carriers need powerful, commercially viable and scalable tools that c...

In this paper we shall try to answer a fundamental question: how to build the Next Generation Network without disruption. The TCP/IP protocol stack has performance limits and the transparent bridge paradigm of Ethernets is complex to scale by lack of addressing hierarchy. To provide both full scalability and high performance, a new Ethernet switching architecture named Universal Ethernet Teleco...

Voice-over-IP is a growing technology. Companies are beginning to consider commercial investments in these services. Will it be able to provide the quality of service necessary to satisfy customers? If not what will need to be done to remedy the situation.

In order to support efficiently the fast-growing demand for transmission capacity, optical packet-switched systems seem to be strong candidates as they allow fast dynamic allocation of WDM channels combined with a high degree of statistical resource sharing. In this work, we propose the architecture of an input/shared-buffered optical packet switching node, for all-optical switching of IP traff...

This document describes the applicability of Multiprotocol Label Switching (MPLS) to traffic engineering in IP networks. Special considerations for deployment of MPLS for traffic engineering in operational contexts are discussed and the limitations of the MPLS approach to traffic engineering are highlighted. Boyle, et al. Informational [Page 1] RFC 3346 Applicability Statement for Traffic Engin...

Optical burst switching provides a feasible paradigm for the next IP over optical backbones. However its burst loss performance can be highly affected by burst contention. In this paper we discuss traffic engineering approaches for path selection with the objective to minimize contention using only topological information. The discussed strategies are based on balancing the traffic across the n...

A simulation model of a Multiprotocol Lambda Switching Control framework for the provisioning of wavelength switched paths in IP-centric optical networks is presented. The required extensions to conventional MPLS, OSPF and CR-LDP for implementing Suurballe’s Open Shortest Cycle algorithm are also outlined.
