T-Vivaldi: TIV-Aware Coordinates System for IP Networks

This paper proposes a new coordinates system (T-Vivaldi) which uses a mechanism to detect and restrict triangle inequality violations. The mechanism can detect TIV with triangle inequality qualification, use a parameter to quantify its degree, and restrict TIV through restricting coordinates update with the parameter. The simulation results show that: compared with Vivaldi, T-Vivaldi can restrict the impact of TIV and increase the predicting accuracy.
