A tecnologia de comutação de rótulos permite alto desempenho e encaminhamento flexível de pacotes da camada 3 usando as informações do rótulo de comprimento fixo mapeadas para o fluxo de pacotes da camada 3 correspondente. Um Label Switching Router (LSR), aplicando tecnologia de comutação de rótulos, encaminha pacotes da camada 3 pelas informações de endereço da camada 3 ou pelas informações do rótulo mapeadas para as informações de endereço da camada 3. Para aplicar a tecnologia de comutação de rótulos aos links ATM, introduzimos um novo identificador denominado Virtual Connection ID (VCID). O valor VCID é compartilhado entre os nós LSR vizinhos. Este artigo propõe um procedimento de notificação VCID e avalia o desempenho do estabelecimento de LSP (Label Switching Path) com o procedimento de notificação VCID. O sistema protótipo pode estabelecer 142.9 LSPs em um segundo com operação em PVC e 10.53 LSPs em um segundo com operação em SVC. De todo o procedimento de estabelecimento de LSP, o procedimento de notificação VCID contribui com apenas 3 ms, correspondendo a apenas 3% de todo o procedimento de estabelecimento de LSP com operação SVC. A avaliação utilizando um rastreamento de tráfego real entre o Japão e os EUA mostra que o número máximo necessário para o estabelecimento de LSP é de 17 por segundo. Com a operação do SVC, o sistema protótipo não será capaz de atingir desempenho suficiente no que diz respeito ao estabelecimento do LSP. Como a contribuição da sinalização ATM é grande, ou seja, 88 ms (= 92.6%), precisamos melhorar o desempenho da sinalização ATM com operação SVC.

Abstract: Label switching technology enables high performance and flexible layer-3 packet forwarding using the fixed length label information mapped to the corresponding layer-3 packet stream. A Label Switching Router (LSR), applying label switching technology, forwards layer-3 packets either by their layer-3 address information or by their label information mapped to the layer-3 address information. In order to apply label switching technology to ATM links, we have introduced a new identifier called a Virtual Connection ID (VCID). The VCID value is shared between the neighboring LSR nodes. This paper proposes a VCID notification procedure and evaluates the performance of LSP (Label Switching Path) establishment with the VCID notification procedure. The prototype system can establish 142.9 LSPs in one second with PVC operation, and 10.53 LSPs in one second with SVC operation. Of the entire LSP establishment procedure, the VCID notification procedure contributes only 3 ms, corresponding to only 3% of the entire LSP establishment procedure with SVC operation. Evaluation using a real traffic trace between Japan and the U. S. shows that the required maximum number for LSP establishment is 17 per second. With SVC operation, the prototype system will not be able to achieve sufficient performance with regard to LSP establishment. Since the contribution by the ATM signaling is large, i. e. , 88 ms (= 92.6%), we need to improve the performance of ATM signaling with SVC operation.
