一种数据包处理方法及装置
摘要：
本发明实施例提供了一种数据包处理方法及装置，处理方法包括：获取SDN中的未封装数据包；判断未封装数据包中是否有使用VLAN字段的需求；当有使用VLAN字段的需求时，在未封装数据包中的原始帧结构中插入两个VLAN字段，生成具有双层VLAN字段的数据包；发送具有双层VLAN字段的数据包至交换机；当没有使用VLAN字段的需求时，在未封装数据包中的原始帧结构中插入第一VLAN字段，生成具有单层VLAN字段的数据包；发送具有单层VLAN字段的数据包至交换机。本发明实施例数据包中的VLAN字段不但能用于网络虚拟化场景中的切片标识，还能用于用户进行VLAN字段的其他应用，解决了VLAN字段无法修改的问题。
摘要（英）：

The invention provides a data package processing method and a data package processing device. The data package processing method comprises steps that an unpackaged data package in an SDN is acquired; whether a requirement on use of VLAN fields exists in the unpackaged data package is determined; when the requirement on the use of the VLAN fields exists, two VLAN fields are inserted in the original frame structure of the unpackaged data package, and a data package having double-layer VLAN fields is generated; the data package having the double-layer VLAN fields is transmitted to a switch; when the requirement on the use of the VLAN fields does not exist, a first VLAN field is inserted in the original frame structure of the unpackaged data package, and a data package having a single-layer VLAN field is generated; the data package having the single-layer VLAN field is transmitted to the switch. The VLAN fields of the data package are used for slice identification of a network virtualized scene, and are also used for the other applications of the VLAN fields of users, and therefore a problem of inability of correcting the VLAN fields is solved.
