Evaluation of Comparison Results


The comparison of TCP and TRUMP/RBCC in Scenario 7 shows that TRUMP/RBCC gives quite different traffic characteristics to TCP, with much less network congestion. RBCC determines source rates which will fully utilise output interfaces (if possible), while maintaining very low output queue sizes in routers. This has the effect of preventing long-term congestion, minimising buffering delays and gives end-to-end delays a very low variance, ideal for time-sensitive traffic. The rates calculated by RBCC are quite close to the optimum rates for Scenario 7.
