Abstract: The queuing models of three typical implementation schemes of selfhealing function in VP switches for backup-VP selfhealing algorithm are given. Computer simulations are made, and detailed analyses of the effect of implementation schemes of selfhealing function and architecture parameters in VP switches on selfhealing performance are presented. Analytic results are helpful to choosing reasonable implementation scheme of selfhealing function, architecture parameters and the number of backup-VP in VP switches for the best selfhealing performance. -
