摘　　要：提出在IEEE 802.3Q协议下应用双层标签的完整实现方案,在多业务接入平台(MSAP)设备中,业务卡本身不具备双标签(QinQ)功能的情况下通过SPI总线将业务汇聚到汇聚卡,利用其汇聚卡中的芯片Marvell6095实现QinQ。通过设置QinQ使能和端口保护实现用户不同的需求,并通过以太网测试仪进行抓包验证。In this paper, an entire solution is proposed for the application of QinQ（double VLAN） in IEEE 802. 3Q, services are gathered in gathering card by SPI bus while the service card itself has no QinQ function in MSAP equipments, and the QinQ function is realized by Marvel16095 in the gathering card. The subscriber s＇ various demands can be achieved by setting the QinQ enabling and the port protection, and the result is proved by the packets captured by the Etbemet tester.
