Hierarchical PCE in GMPLS-based Multi-Domain Wavelength Switched Optical Networks
GMPLS-based Hierarchical PCE Wavelength Switched Optical Networks
2011/5/18
Hierarchical PCE is evaluated in GMPLS-based multi-domain WSONs. Simulations show that PCE providing edge nodes sequence using detailed information of inter-domain links achieves the best performance ...

Path Computation Element GMPLS-enabled Wavelength Switched Optical Networks
2008/8/3
The paper presents the design, implementation and deployment of a Path Computation Element for GMPLS wavelength switched networks with shared path protection, assessing the feasibility but with increa...
Routing and Wavelength Assignment in PCE-based Wavelength Switched Optical Networks
Routing Wavelength Assignment PCE Switched Optical Networks
2008/8/3
Implementations of three PCE-based WSON architectures are proposed. If the PCE performs wavelength assignment utilizing a path set precomputed at ingress nodes, complexity is effectively traded off wi...
