There is nothing wrong with using GMPLS only on DWDM. ASON looks at the network more from the architectural and global view ( as compared to pure GMPLS). Also the network management is more defined in ASON ( compared to pure GMPL).you can run GMPLS alone without ASON too. Usually you cannot run ASON without GMPLS as ASON needs GMPLS for signaling. GMPLS is more generalized and not limted to optical layers, it can be used for example in MPLS-TP also.
Hi Faisal,
Why don’t we use a pure GMPLS on DWDM and we use ASON/GMPLS?what is wrong with using pure GMPLS on DWDM?
Hi Hama,
Thanks for stopping by!
