Avaliação de desempenho do protocolo DCCP para redes de alta velocidade
Resumo
Os protocolos existentes na camada de transporte na Internet, TCP e UDP, não oferecem serviços para transmissão eficiente de fluxos multimídia, porém, este último é adotado com maior freqüência para o uso de tais aplicações, o que pode colocar em risco o bom funcionameto da Internet, uma vez que o mesmo não implementa nenhum tipo de mecanismo de controle de congestionamento. Uma proposta de um novo protocolo da camada de transporte, chamado DCCP, foi elaborada para atender a demanda de tais aplicações e substituir o protocolo UDP. O presente artigo avalia o desempenho do protocolo DCCP, a fim de se verificar a adequabilidade da sua adoção em redes de alta velocidade.Referências
