Aiming at better resource utilization, an important requirement of future optical transport networks is the capability to accommodate subwavelength client flows efficiently. This can be put into action thanks to the enhanced traffic engineering (TE) protocols provided within the generalized multiprotocol label switching (GMPLS) standardization. The present paper concentrates on the design and implementation...
Some ideas about different traffic aggregation strategies to optimize the use of optical channels in wavelength routed networks are presented. The considered scenario assumes an integrated GMPLS control plane, responsible for the management of requested electrical IP connections, as well as the underlying lightpaths. Different grooming policies which have been studied are presented, highlighting potential...
