Abstract :
Within the generalized multi-protocol label switching (GMPLS), link management protocol (LMP) has been proposed to maintain the connectivity of the out-of-fiber control plane. In this paper, we analytically quantify the impact of control plane link failures on whole network performance. Then, we use the obtained results to suggest the keep-alive interval for LMP, introducing the least overhead to the control network while keeping an acceptable network grade of service (GoS).
