A flexible method to support VLAN stacking and VLAN in node type ONU
Cheng Chuanqing, Wang Li · 2009
Since the aggregation network is Ethernet-based and the access node and broadband network gateway are both equipped with standard Ethernet interfaces, it is natural to try to address the above requirements with existing Ethernet layer mechanisms. The standard virtualization mechanism for Ethernet networks is VLAN tagging. VLAN tagging is defined in IEEE 802.1Q and is being enhanced by 802.1ad. This paper discuss how to support VLAN stacking in node type ONU or in DSLAM. By the method, 802.1Q and 802.1ad can be supported in the same system flexibly.
