Endereço de destino 7 LAN MODELO ISO / OSI Layer 7 Aplicação Interface entre o software de rede e os softwares de aplicação do usuário. Layer 6 Apresentação Representação de dados. Layer 5 Sessão Tabela de endereçamento e segurança. Layer 4 Transporte Controle da transmissão de ponta a ponta. Layer 3 Rede Estabelece conexão lógica cuidando do tráfego e roteamento (p.ex., routers, routing switches) Layer 2 Enlace Responsável pelo acesso lógico ao ambiente

Introduction to 100VG AnyLAN and the IEEE 802.12 Local Area Network Standard 100VG-AnyLAN provides a 100-Mbit/s data rate with guaranteed bandwidth and maximum access delay for time-critical applications such as multimedia, using existing building wiring. It uses demand priority protocol. Developed by Hewlett-Packard and now supported by over 30 companies ranging from integrated circuit vendors to systems suppliers, demand priority is well on its way to becoming the IEEE 802.12 standard.

before either starts to send application data to the other. Provides reliable data transfer, i.e., all application data sent by one side of the connection arrives at the other side of the connection in order and without any gaps. Provides flow control, i.e., it makes sure that neither end of a connection overwhelms the buffers in the other end of the connection by sending to many packets to fast. Provides congestion control, i.e., regulates the amount of data that an application can send…
