Avaliação de Desempenho do Protocolo DCCP na Presença de Erros de Transmissão

Priscila Gonçalves DoriaMarco Aurélio Spohn

DCCP is an outstanding transport protocol that has attracted the attentionof the scientific community for its rapid progress and good results. Previousworks have compared the peformance of DCCP with standard transportprotocols, however limited to a single protocol per link, in assumed errorlesslinks. We evaluate the performance of two DCCP variants and TCP SACK in amore realistic scenario, where protocols fight for the same link and transmissionerrors can occur. The results point to a better performance of DCCP, speciallythe CCID3 variant, when there are link errors, and TCP SACK outperformsDCCP variants in errorless scenarios.
