Data processing method, controller and forwarding device

Abstract

The embodiment of the present application discloses a data processing method. The method in this embodiment of the present application includes: the controller acquires a request message; the controller creates at least two network slices according to the request message, the at least two network slices include a first network slice and a second network slice, and the first network The slice and the second network slice share the resource objects of each layer in the network slice architecture; the controller sends the information of the at least two network slices to the target forwarding device, and the information of the at least two network slices includes the information of the first network slice Fragmentation information and information of the second network fragmentation, the information of the first network fragmentation indicates the resource objects of each layer in the network fragmentation architecture associated with the first network fragmentation; the information of the second network fragmentation indicates the second The resource objects of each layer in the network fragmentation architecture associated with the network fragmentation. Each layer in the network fragmentation architecture includes at least one of the following layers: management layer, control resource layer, business layer, protocol layer, network layer, and forwarding resource layer.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data processing method, a controller and a forwarding device. Background technique [0002] In order to cope with the emerging or upcoming various user use cases, different user use cases have significant differences in network performance requirements, such as the fifth generation mobile communication system (fifth generation, 5G), such as the new air interface (newradio, NR) A notable feature is that a network architecture of network slice (NS) is proposed. [0003] Currently, network fragmentation can be supported by extending the multiple topology (MT) protocol. Each network fragment has a multiple topology identification (MT ID), and each network fragment corresponds to forwarding resources and an independent topology. . [0004] However, the solution to support network sharding by extending the MT protocol leads to a strong binding between the networ...

Problems solved by technology

[0004] However, by extending the MT protocol to support network sharding, the network sharding technology is strongly bound to the MT protocol and strongly associated with the MT technology, which has relatively large limitations.
