Avaliação de Desempenho do DCCP, CTCP e CUBIC, Usando Tráfegos VoIP
Resumo
O DCCP é um proeminente protocolo de transporte que vem atraindo a atenção da comunidade científica pelos seus rápidos avanços e bons resultados. Trabalhos anteriores comparam o desempenho do DCCP com protocolos clássicos, assumindo um protocolo de cada vez por enlace, sob tráfego CBR. Neste trabalho, o DCCP (CCID2 e CCID3) é comparado a duas variantes modernas e representativas do TCP (CTCP e CUBIC), onde ocorre disputa em pares pelo enlace. Os resultados sugerem que, sob contenção, o desempenho do CCID2 é superior ao do CCID3; o CUBIC obtém melhor vazão, porém com maior descarte de pacotes e menor taxa de entrega; o CTCP é superado pelo CCID2 e pelo CUBIC na maioria dos cenários, superando apenas o CCID3.Referências
