Focando em um nó de controle de serviço de controle distribuído (SCP) que abriga um banco de dados (BD) distribuído em vários módulos, este artigo propõe uma arquitetura SCP distribuída autônoma usando acesso multicast ao BD distribuído e destaca suas áreas de aplicação. Assumimos como condição básica que nem a rede nem os demais módulos do sistema tenham conhecimento da configuração do banco de dados. Com base nesta condição, propomos dois métodos básicos: uma abordagem unicast em que o módulo de gerenciamento do banco de dados selecionado aleatoriamente pela rede roteia a solicitação de acesso ao banco de dados para o módulo onde residem os dados de destino (Método A), e um método multicast em que as solicitações de acesso ao banco de dados são transmitidas para todos os módulos (Método B). É feita uma avaliação quantitativa do número de módulos necessários e do desempenho de comunicação necessário entre os módulos, que é determinado pela capacidade da memória principal e pela capacidade de processamento dos processadores. Com base nos resultados, concluímos que o Método B explora melhor as vantagens da tecnologia de distribuição autônoma de módulos dentro dos limites em que a economia da sobrecarga de comunicação entre módulos não é prejudicada. Além disso, no caso de um módulo falhar no Método B, é proposto um esquema no qual o módulo defeituoso é cortado do grupo multicast e o multicast continua. Isto poderia ser implementado de forma mais eficaz utilizando uma rota separada sob controle de hardware que é independente da rota de comunicações on-line entre os módulos.

Abstract: Focusing on a distributed control service-control-node (SCP) that houses a database (DB) distributed across multiple modules, this paper proposes an autonomous distributed SCP architecture using multicasting access to the distributed DB, and highlights its application areas. We assume as a basic condition that neither the network nor the other modules in the system are aware of the DB configuration. Based on this condition, we propose two basic methods: a unicast approach in which the DB management module that is selected at random by the network routes the DB access request to the module where the target data resides (Method A), and a multicast method in which DB access requests are broadcast to all modules (Method B). A quantitative evaluation is made of the number of required modules and required communications performance between modules which is determined by the capacity of the main memory and processing capacity of the processors. Based on the results, we conclude that Method B better exploits the advantages of module autonomous distribution technology within the limits that the economy of inter-module communication overhead is not impaired. Furthermore, in the event a module fails in Method B, a scheme is proposed in which the defective module is cut out of the multicast group, and multicasting continues. This could be implemented most effectively using a separate route under hardware control that is independent of the on-line communications route between modules.
