short for high-speed digital user line. It is a new DSL technology, known as xDSL's End-level technology. The maximum downlink rate of VDSL in a short distance can reach 55 Mbit/s, and the uplink rate can reach 19.2 Mbit/s. Because it directly uses the Ethernet frame format at the link layer, VDSL and Ethernet provide completely consistent support for IP services and are currently the most ideal xDSL technology for carrying IP addresses and Ethernet networks, it is also the best method to repla
, the access process of Broadband Access Servers relies on the underlying data link layer, mainly the ATM layer and Ethernet layer) to encapsulate and reorganize data packets. Taking advantage of the technical features of the underlying layer, not only is the access networking flexible, but also can effectively bind the technical advantages of ATM and Ethernet to ensure service quality. Specifically, through RFC1490 and RFC1483 Layer 2 bridging technologies
