Abstract

The embodiment of the present invention provides a data packet processing method and device. The processing method includes: obtaining an unencapsulated data packet in the SDN; judging whether there is a demand for using a VLAN field in the unencapsulated data packet; , insert two VLAN fields into the original frame structure in the unencapsulated data packet to generate a data packet with double-layer VLAN fields; send the data packet with double-layer VLAN fields to the switch; when there is no need to use the VLAN field, in Inserting the first VLAN field into the original frame structure in the unencapsulated data packet to generate a data packet with a single-layer VLAN field; sending the data packet with a single-layer VLAN field to the switch. The VLAN field in the data packet in the embodiment of the present invention can not only be used for the slice identification in the network virtualization scene, but also can be used for other applications of the VLAN field by users, which solves the problem that the VLAN field cannot be modified.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data packet processing method and device. Background technique [0002] SDN (Software Defined Network) is a new type of network architecture that provides a new way to realize network virtualization. SDN separates the control plane of network equipment from the data plane through the OpenFlow protocol, thus realizing network The flexible control of traffic makes the network more intelligent as a pipeline. Among them, OpenFlow is a network communication protocol that can control the forwarding plane of a network switch or router. In network virtualization, a collection of logical resources belonging to the same virtual network is usually called a slice. The slice identification method is a basic and important part of network virtualization. It is used to identify different slices to ensure that network devices can Identify traffic from different slices to ensure ...
