There is a common misconception among Internet Service Providers that PPPoE and Hotspot can provide security in a Wired or Wireless Networks. ISP's do not like to hear that their Networks are insecure only with this methods, but in fact in most cases they really are. All the time the Providers and their customers are exposed do DoS and man-in-the-middle attacks. The future of those operators is strongly tied to the security measures they will implement on their networks.The main purpose of this presentation is to show the weakness of the methods commonly used and the way to ensure real security.

The purpose of the presentation is to clarify what is QoS - Quality of Service in the environment of a Computer Network managed by a Mikrotik RouterOS Gateway.
The presentation deals with the system configuration, presenting a global vision in a technical and managerial point of view of this important concept that has fundamental importance for data and multimedia transmission. It will be showed in a generic and global way, how IT administrators should see, plan and implement QoS on their Networks as well the protocols, techniques and trends. The presentation will cover QoS for traditional and Wireless networks with emphasis in VoIP.

Portugese: Aplicando políticas de QoS.

A apresentação tem o objetivo de esclarecer o que é QoS – Quality of Service - no ambiente de uma Rede de Computadores, gerenciadas por um gateway Mikrotik RouterOS.
O apresentação trata das configurações do sistema, apresentando uma visão global, tanto gerencial quanto técnica, sobre esse conceito abrangente – e de suma importância para as transmissões de dados e multimídia. Serão demonstradas, de uma maneira ampla e genérica, as formas como administradores de T.I. devem enxergar, planejar e implementar suas redes com QoS, e os protocolos, técnicas e tendências existentes para tal. Serão abordadas as QoS para redes tradicionais, para wireless, e VoIP.

Wireless Mesh Networks have been widely used for providing citywide
broadband service. There are several Companies in the market offering
their solutions, in most case proprietary, to attend the growing
demand. Mikrotik RouterOS offers a lot of options for Wireless Mesh
Networks deployments that can be configured in a proprietary mode for a
robust performance or according to standards, allowing the use Mikrotik
together of commodity equipment. The main goal of the presentation is
to give an overview of the Mesh Networks solutions in the market, the
basic guidelines to implement Mesh with Mikrotik RouterOS and to report
experiences of practical implementations.
