Quality of service control for rt-VBR connections in ATM networks

Nowadays, networks must support applications such as: distance learning, electronic commerce, access to Internet, Intranets and Extranets, voice over IP (Internet Protocol) and many others. These new applications, employing data, voice, and video traffic, require high bandwidth and Quality of Service (QoS). The ATM (Asynchronous Transfer Mode) technology, together with dynamic resource allocation methods, offers network connections that guarantee QoS parameters, such as minimum losses and delays. This paper presents a system that uses Network Management Functions together with dynamic resource allocation for provision of the end-to-end QoS parameters for rt-VBR connections.

The collective purchases translate into new business strategies that so far are poorly studied, but they have modifyied considerably the forms of consumption through the consumers individualisation, which causes changes in society's routine. The analysis of the theme was performed by study cases of collective shopping places in the city of Campinas, country of the state of São Paulo, and on its influence in the metropolitan area, which intented to understand, through custumers interviews, the contradictions and peculiarities of this service that has increased each day more . For this purpose, the research methodology is focused on the consumer , that's because the process of productive change tied to forms of trade and distribution of goods have been transforming social values considerably, based increasingly on impulsive consumming . Thus, to understand how the electronic commerce and more specifically the collective shopping websites works, it's necessary to examine the forms of commerce and the consumer's behavior in order to explain the city organization and the contradictions of the geographic space

An attack signature model to computer security intrusion detection

Internal and external computer network attacks or security threats occur according to standards and follow a set of subsequent steps, allowing to establish profiles or patterns. This well-known behavior is the basis of signature analysis intrusion detection systems. This work presents a new attack signature model to be applied on network-based intrusion detection systems engines. The AISF (ACME! Intrusion Signature Format) model is built upon XML technology and works on intrusion signatures handling and analysis, from storage to manipulation. Using this new model, the process of storing and analyzing information about intrusion signatures for further use by an IDS become a less difficult and standardized process.

Market-driven security-constrained transmission network expansion planning

This paper presents a Bi-level Programming (BP) approach to solve the Transmission Network Expansion Planning (TNEP) problem. The proposed model is envisaged under a market environment and considers security constraints. The upper-level of the BP problem corresponds to the transmission planner which procures the minimization of the total investment and load shedding cost. This upper-level problem is constrained by a single lower-level optimization problem which models a market clearing mechanism that includes security constraints. Results on the Garver's 6-bus and IEEE 24-bus RTS test systems are presented and discussed. Finally, some conclusions are drawn. © 2011 IEEE.
