PCE is an emerging technology to aggregate path computation tasks in some certain elements. The location of these elements may influence network performance. In this paper, an ILP model for PCEs location problem is formulated and a heuristic algorithm is proposed. Simulations are conducted to evaluate the effectiveness of the algorithm presented.
MPLS Transport Profile (MPLS-TP) technology is gaining importance as it becomes a dominant solution for a converged transport network in recent years. MPLS-TP ring protection mechanism defined in standards provides the ability to restore traffic delivery following failure or degradation of network resources to meet carrier-class transport network requirements. The article outlines MPLS-TP ring protection...
As most of the carriers have extended their circuit transport networks with packet transport capabilities due to the inefficient transport network architecture, the controlling manner developed silently. Multiple service transport platform is the newly proposed packet based transport technology and the standardization process is very fast. GMPLS is considered to be the future controlling technologies...
It is essential for us to do research on collaboration mechanism in management-control plane in intelligent optical networks. We propose an interaction schemes using mobile agent between the control plane and management plane to solve information collection delay and management messages congestion. We construct the integrated platform by mobile agent.
