Detailed Description

fig. 1 is a schematic diagram of a correspondence relationship between a client side and a network slice in the network slice, as shown in the figure, a currently existing scheme is generally:

the line side is divided into slices based on time slots or wavelengths;

and the client side divides slice attribution according to the physical ports, and the physical ports of the client side are mapped with the time slots of the line side to realize slice.

The granularity of the client-side physical port is too large to realize flexible client-side service scheduling and slicing division;

the problem of this solution is that the physical connection of the client side port is fixed, and the user cannot flexibly design the mapping relationship between the client side service and the slice.

And therefore, the current OTN network slicing technology and scheme cannot meet the requirement of flexible slicing of users.

Based on this, the embodiment of the invention provides an OTN network slice implementation scheme, which implements service and slice mapping based on a VLAN (Virtual LAN) configured by a user, thereby implementing flexible slice of the OTN.
