ITU-T Study Group 15 has introduced a new flexible grids technology of DWDM network which is an effective solution to improve the efficiency of spectrum resource utilization. This memo extends the OSPF-TE protocol to support constraint-aware routing and spectrum assignment (RSA) in flexi-grid networks.
