Virtual connections in packet switched networks is increasing faster, in particular over the Internet, using MPLS and GMPLS evolution has produced a significant amount of studies on traffic engineering protocols, especially with regard to the different ways to provide quality of service over connections. This article presents a model to characterize the reliability of these types of networks, in computing...
Deep Packet Inspection technology has generated such recent debates and expectations for its operation. If we take as a basis the operators and ISPs interfering network service platforms and equipment capable of analyzing all traffic to Internet subscribers, this fact has led to all kinds of disputes such as who or what agency regulates that interfered and analyzed data are not made public, maintain...
Within the VolP networks environment, there are three protocols that solve the problem of voice packet signaling, known as "highlight protocols": H323, SIP and IAX. Particularly, this document focuses on a specific difference between SIP and IAX: the bandwidth, which is an essential parameter in order to design and optimize a VoIP network for an organization. One of the most important factors...

this article presents a model development of the round trip time in a TCP/IP data network using Nonlinear System Identification techniques, normally employed in Process Control modeling. To achieve this goal, it was necessary to study the tools and techniques used by Process Control Engineering and the data collection in TCP/IP data networks. This work demonstrates the effective use of these techniques...
This article presents the main features of Layer 1 L1VPN Virtual-Private Networks. It focuses particularly on aspects such as the provision and modeling of services within inter-domain environments, the supply of a Layer 1 VPN, the existent and proposed architectures, and the type of services offered through Networking Technologies together with Optical Transmission. Interaction between these aspects...
This paper studies MPLS/VPN/BGP Networks with respect to the RFC 4364 [1], which corresponds to our backbone-level research setting of interest. The main focus is on intranet systems connection and the assessment of the BGP algorithm when connecting MPLS Routers - CE (Customer Edge) and PE (Provider Edge). The assessment covers VRF (Virtual Routing and Forwarding) establishment and its performance...
this project is a proposal, based on innovative Bluetooth Marketing Services, whose main objective is to facilitate the dissemination of information via Bluetooth in tourist-commercial sectors. This proposal is supported by the analysis, design and construction of a software application resulting from the abstraction of previous analysis and design of a directory-based service.
The following article presents the criteria and strategies for a solution convergence networks to replace legacy data and voice as well to increase their operational efficiencies and security, while demonstrating the reduction of costs, ensuring the quality levels as well as the interaction with new technologies of voice and data. During the development of this document sets out the purpose and provides...

New applications like VoIP and video conferencing are sensitive to network performance, therefore making the network capacity provide quality of service is increasingly important. IPv6 was developed to solve some of the problems of IPv4, such as QoS, security and the IPv4 addresses reduction. Current IP networks provide better traffic delivery effort providing partial guarantees in terms of Quality...
This paper presents an evaluation of the specifications of the QoS policies for trunk interfaces Metro and Core equipment MPLS over ASON. This paper is based in a project named "Prototype for evaluation of the costs and technical benefits in backbone networks with next-generation services based on ASON (Automatic Switched Optical Network)". The first part defines the services provided by...
