Abstract 

   Optical networks which support a large number of emerging 
   applications, such as 5G, Cloud Computing, Big Data, Internet of 
   things, autonomous driving, etc., play an increasingly important 
   role in the current world. All the time spectrum resources in 
   optical networks have been treated equally. All spectrum resources 
   form a resource pool which is allocated to applications bit by bit 
   until it is all used up. Although this pattern reduces the 
   complexity of resource maintenance, it has poor flexibility and high 
   operation complexity for different types of applications. This draft 
   proposes a framework of centralized control and distributed function 
   slicing for fast connection establishment and fault recovery in 
   optical networks. The proposed framework divides all spectrum 
   resources into four functional areas, i.e., optical channel area, 
   fault recovery area, resource pool area, and the reserved functional 
   area. A functional area is responsible for a specific network 
   function. This framework improves the flexibility of optical 
   networks and can achieve fast connection establishment and fault 
   recovery for the request with a highest service level.
