Resumo


A ausência de pressuposições básicas do TCP/IP em Redes Tolerantes a Atrasos e Desconexões (DTNs) faz com que o emprego de abordagens convencionais de gerenciamento seja mais difícil. Este artigo avalia as forças e fraquezas das tradicionais abordagens de gerenciamento centralizada, hierárquica e distribuída, quando empregadas em um ambiente DTN. Um simulador DTN foi usado para avaliar duas métricas relacionadas ao uso das abordagens de gerenciamento: a taxa de sucesso de operações de polling e a latência da operação de monitoramento. Os resultados alcançados no trabalho possuem potencial para guiar o desenvolvimento de novas soluções para o gerenciamento de DTNs e melhorar sua tolerância a falhas.
