Abstract

"DISPOSITIVO DE ACESSO PROGRAMáVEL PARA UM SISTEMA DE ACESSO à REDE DISTRIBUìDA". Trata-se de um dispositivo de acesso programável para uso em um sistema de acesso à rede que inclui a primeira e a segunda interfaces com a rede (rede de acesso 32, 58) através das quais pacotes são comunicados com uma rede, uma tabela de envio (86) utilizada para rotear a comunicação dos pacotes entre a primeira e a segunda interfaces com a rede e um filtro de cabeçalho de pacote (80, 90). O filtro de cabeçalho de pacote (80, 90) identifica mensagens recebidas em uma dentre a primeira e a segunda interface com a rede na qual serviços baseados em plano de ação são para ser implementados e passa as mensagens identificadas via uma interface de mensagem (100) para um processador externo (42) para processamento. Nas modalidades preferidas, o filtro de cabeçalho de pacote (80, 90) é capaz de filtrar pacotes em relação ao processamento de serviço baseado na informação de protocolo pertencendo às camadas de protocolo de nível maior do que a camada 3. Nas modalidades preferidas, o dispositivo de acesso programável também pode incluir um monitor de utilização que relata eventos, tal como níveis de atividade de sessão, para o processador externo (42), uma polícia (82) que polícia pacotes por referência aos parâmetros de tráfego programados e um programador de atividades que programa as atividades (96) de transmissão dos pacotes de saída para suportar múltiplas qualidades de classes de serviço.
