Although inter-domain egress is tunable by TIE, it is too complex to compute its parameters, and it is impossible to tune its egress on different traffic load. Accordingly, an adaptive tunable inter-domain egress selection algorithm (ATIE) is proposed. ATIE can satisfy traffic engineering and network robustness by tuning parameter T with current traffic load. Experiments demonstrate that our solution can achieve a good balance between control plane sensitivity and traffic engineering adapting to different network traffic load.
