PTIT, Ho Chi Minh 1 This paper presents the ability to quickly reroute traffic around error or congestion in a Label Switched Path (LSP) of MPLS networks. When label switched path established unusable (e.g. due to a physical link or switch failure) data may need to be re-routed over an alternative path. This paper include 5 parts. Part 1 introduce the essential of alternative path in MPLS when ...

ties and consequences in the context of designing a network AN INTERFACE ARCHITECTURE FOR A LOW-LATENCY NETWORK OF WORKSTATIONS USING 10 GBIT/S SWITCHED LAN TECHNOLOGY A network of workstations, NOW, based on standard busbased multiprocessor nodes, interconnected by standard LAN technology, may be a very cost effective alternative to current large, tightly coupled systems with dedicated interna...

There has recently been considerable interest in design of low-complexity, myopic, distributed and stable scheduling policies for constrained queueing network models that arise in the context of emerging communication networks. Here, we consider two representative models. One, a model for the collection of wireless nodes communicating through a shared medium, that represents randomly varying nu...

in the present paper, we develop a modified pseudospectral scheme for solving an optimal control problem which is governed by a switched dynamical system. many real-world processes such as chemical processes, automotive systems and manufacturing processes can be modeled as such systems. for this purpose, we replace the problem with an alternative optimal control problem in which the switching t...

PHS/DECT networks are “micro-cellular” radio access systems. Unlike cellular or 3G (third-generation) wireless networks they don’t require comprehensive, expensive supporting network architectures. Instead they inter-work with existing systems, such as PBXs (private branch exchanges), the PSTN (public switched telephone network), cellular networks, and ISDN (integrated services digital network)...

Service differentiation is a crucial issue in the next -generation Optical Packet Switched networks. In this paper we examine how bursty traffic influences the performance of a service differentiated Optical Packet Switched network. By using time -continuous Markov chains, we derive explicit results for the packet loss rates in the case of a bursty hyper-exponential arrival process. Results ind...

A criterion for a three-stage network to be strictly non-blocking is presented which is very general in its application. The criterion distinguishes between channel grouping and link speedup as methods of increasing the bandwidth available to calls. It may be applied to both circuit-switched and packet-switched networks. The non-blocking conditions for various networks are shown to be special c...

A switched-current integrated circuit, which realizes the chaotic neuron model, is presented. The circuit mainly consists of CMOS inverters that are used as transconductance amplifiers and nonlinear elements. The chip was fabricated using a 1.2 μm HP CMOS process. A single neuron cell occupies only 0.0076 mm2, which represents an area smaller than the one occupied by a standard bonding pad. The...

A non-linear model for the description of packet-switched communication networks is presented. This model is combined with a model of an additive increase, multiplicative decrease end-to-end controller to obtain a global description of a controlled packet switched network with buffering delays. The global stability of this general model is then analysed using singular perturbation analysis. It ...

The Ethernet network is increasingly used for the industrial communications which are strongly timeconstrained. This paper presents both a method (based on the genetic algorithms) to design switched Ethernet architectures and a method (based on the network calculus) to evaluate these network architectures in term of maximum end-to-end delay.
