Abstract

DCCP is a prominent transport protocol that has attracted the attention of the scientific community for its rapid progress and good results. Previous works have compared the performance of DCCP with standard transport protocols, assuming a single protocol per link and using the constant bit rate traffic pattern. In this paper, we evaluate the performance of DCCP (CCID2 and CCID3) with modern and representative TCP variants (CTCP and CUBIC). Results show that CCID2 performs better than CCID3 in contention; CUBIC has achieved better throughput, but with higher packet dropping and lower delivery rate; CTCP is outperformed by DCCP CCID2 and CUBIC in most scenarios, outperforming only CCID3.
