Title
How robust is the n-cube?
Abstract
The n-cube network is called faulty if it contains any faulty processor or any faulty link. For any number k we want to compute the minimum number f(n, k) of faults which is necessary for an adversary to make every (n - k)-dimensional subcube faulty. Reversely formulated: The existence of an (n - k)-dimensional non-faulty subcube can be guaranteed, if there are less than f(n, k) faults in the n-cube. In this paper several lower and upper bounds for f(n, k) are derived such that the resulting gaps are ''small.'' For instance if k = 2 is constant, then f(n, k) = @q(logn). Especially for k = 2 and large n: f(n, 2) @? [[@a"n@?]: [@a"n]@? + 2], where @a"n =logn + 1/2 log log n + 1/2. Or if k = @w(log log n) then 2^k
