Design of supreme PCE architecture & protocol to compute an optimal path

As changing usage patterns and the value of network users, recovery techniques for building secure networks has become an important issue to establish reliable communication networks. It needs some solutions such as TE to maintain network resources efficiently based on control plane, data plane on GMPLS. But it is very difficult to serve these efficient multi-layer TE solution because of limited visibility to network resources. Standards for PCE and GCO still did not occur, because the optimal structure of the PCE path computation for design and delivery of information throughout the design for the PCEP, highspeed bandwidth networks, such as considering the specific factors to calculate the optimal path is expected to be performed.
