Detailed Description

The inventor notices in the process of invention that:

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

the line side divides the slices based on time slots or wavelengths;

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

The granularity of the physical port at the client side is too large, so that flexible service scheduling and slice division at the client side cannot be realized;

the problem with this scheme is that the physical connections of the client-side ports are fixed, and the user cannot flexibly design the mapping relationship between the client-side traffic and the slices.

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

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

In the implementation, the OTN edge device will be mainly described by taking CPE (Customer Premise Equipment) as an example, because CPE is a device that is relatively commonly used at present, and is therefore described by taking CPE as an example here; however, other devices are also possible, and in fact, as long as the network device capable of receiving the signals from the client side and switching them to the corresponding network slice can be used to implement the present invention, the CPE is only used for teaching the skilled person how to implement the present invention specifically, but does not mean that only this specific device type of CPE can be used, and the corresponding device can be selected and used in the implementation process according to practical needs.

In the implementation, the network entity that manages the network slices and the corresponding relationships is mainly described by taking the control center as an example, because the control center is a network entity that is most easily implemented with the technical solution provided by the embodiment of the present invention in the currently adopted network architecture, the control center is described here by taking the control center as an example; however, other network entities are also possible, and in fact, as long as the network entities capable of managing the network slices and the corresponding relationships can be used to implement the present invention, and meanwhile, the management of the network slices and the corresponding relationships is not necessarily implemented on the same network entity, but can also be distributed to a plurality of network entities, so that the management center is only used to teach those skilled in the art how to implement the present invention specifically, but not to be implemented only on the management center, and the corresponding network entities can be selected in the implementation process according to practical needs.
