摘　　要：通过重新定义IPv6报头traffic class字段中的预留位(CU)和IPv6流标签的结构化编码方法,定义了流标签携带地域信息、应用信息、端口信息的编码结构,提升了根据流标签值识别业务流量的能力,并探讨了在IPv6过渡环境中实现基于流标签的服务质量差异化方法。By redefining the reserved CU bits in IPv6 header traffic class field and the structured code of IPv6 flow label, the region information, application information, port number or other information were defined. The capability of identifying traffic type based on flow label code value was improved, the way to use the IPv6 flow label for differentiated service in IPv6 transiting network was discussed.
