Neste artigo, é proposta uma técnica de monitoramento de fluxo paralelo que permite medições precisas do atraso ponta a ponta das redes. Em tarefas de monitoramento de rede, pesquisadores e profissionais de rede geralmente monitoram vários fluxos de sondagem para medir atrasos em vários caminhos em paralelo. Entretanto, quando eles medem um atraso ponta a ponta em um caminho, as informações dos fluxos, exceto o fluxo ao longo do caminho, não são utilizadas no método convencional. Geralmente, os caminhos dos fluxos partilham partes comuns na monitorização paralela. No método proposto, informações de fluxos em caminhos que compartilham partes comuns são utilizadas para medir o atraso em um caminho, convertendo parcialmente os resultados da observação de um fluxo para aqueles de outro fluxo. Realizamos simulações para confirmar que os resultados da observação de 72 fluxos paralelos de medição ativa são apropriadamente convertidos entre si. Quando o 99º percentil do atraso ponta a ponta para cada fluxo é medido, a precisão do método proposto é duplicada em comparação com o método convencional.

Abstract: In this paper, a parallel flow monitoring technique that achieves accurate measurement of end-to-end delay of networks is proposed. In network monitoring tasks, network researchers and practitioners usually monitor multiple probe flows to measure delays on multiple paths in parallel. However, when they measure an end-to-end delay on a path, information of flows except for the flow along the path is not utilized in the conventional method. Generally, paths of flows share common parts in parallel monitoring. In the proposed method, information of flows on paths that share common parts, utilizes to measure delay on a path by partially converting the observation results of a flow to those of another flow. We perform simulations to confirm that the observation results of 72 parallel flows of active measurement are appropriately converted between each other. When the 99th-percentile of the end-to-end delay for each flow are measured, the accuracy of the proposed method is doubled compared with the conventional method.
