Abstract Reliability problems on Exchanged Hypercube interconnection network (EH(s, t)) regard as one of important candidates of network models in large-scale processor systems are concerned by people. The extra connectivity, which is an important measure in evaluating the reliability, is utilized to analyze the reliability of exchanged hypercube interconnection network. Then the 2-extra vertex connectivity (k2(EH(s, t))) and 2-extra edge connectivity (λ2(EH(s, t))) of exchanged hypercube interconnection network are obtained. The conclusions are that k2(EH(s, t))= 3s-2 for t≥s≥2; and λ2(EH(s, t))=3s-1 for t≥s≥3 The analysis shows that the 2-extra connectivity is much superior to the traditional connectivity in evaluating the reliability of exchanged hypercube interconnection network.
