A velocidade de encaminhamento dos roteadores IP deve crescer para acomodar a crescente quantidade de tráfego na Internet. MPLS, que depende do alto poder de processamento das camadas inferiores, é uma solução e está em desenvolvimento. Por outro lado, uma rede WDM era esperada como uma rede de alta velocidade, mas também é chamada de rede estúpida devido à falta de granularidade de tráfego. Para fazer a ponte entre essas duas camadas, foi proposta uma rede IP sobre WDM através de um conceito de MPLS. Esta rede tem potencial para utilizar efetivamente a grande capacidade de transmissão fornecida pela tecnologia WDM. Neste artigo, projetamos redes IP sobre WDM que reconfiguram o roteamento IP e os lightpaths a cada dia ou mês. Formulamos um problema que maximiza o rendimento da rede com base na programação linear inteira. Através de exemplos numéricos, mostramos que o aumento do throughput da rede IP sobre redes WDM é maior do que o das redes IP. Mostramos também a área onde este método é aplicável à rede reconfigurável.

Abstract: The forwarding speed of IP routers must grow to accommodate the skyrocketing amount of traffic on the Internet. MPLS, which relies on the high processing power of lower layers, is a solution and it is under developing. On the other hand, a WDM network has been expected as a high-speed network, but it is also called a stupid network because of lacking its traffic granularity. In order to bridge between these two layers, an IP over WDM network by a concept of MPLS has been proposed. This network has a potential to effectively use large transmission capacity provided by WDM technology. In this paper, we design IP over WDM networks that reconfigure IP routing and lightpaths each day or month. We formulate a problem that maximizes the network throughput based on integer linear programming. Through numerical examples, we show that the increase of the network throughput in IP over WDM networks is larger than that of IP networks. We also show the area where this method is applicable to the reconfigurable network.
