Virtual Leased Line
Virtual leased lines (VLL), also referred to as virtual private wire service (VPWS) or EoMPLS (Ethernet over MPLS), is a way to provide Ethernet-based point to point communication over Multiprotocol Label Switching (MPLS) or Internet Protocol networks. VLL uses the pseudo-wire encapsulation for transporting Ethernet traffic over an MPLS tunnel across an MPLS backbone. VLL also describes a point to point bonded connection using the broadband bonding In computer networking, link aggregation is the combining ( aggregating) of multiple network connections in parallel by any of several methods, in order to increase throughput beyond what a single connection could sustain, to provide redund ... technology. Types There are 5 types of VLLs: * Epipes: Emulates a point-to-point Ethernet service. VLAN tagging, VLAN-tagged Ethernet frames are supported. Interworking with other Layer 2 technologies is also supported. * Apipes: Emulates a point-to-point ATM (Asynchronous Transfer Mode) ...

Ethernet
Ethernet () is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility. Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses coaxial cable as a shared medium, while the newer Ethernet variants use twisted pair and fiber optic links in conjunction with switches. Over the course of its history, Ethernet data transfer rates have been increased from the original to the latest , with rates up to under development. The Ethernet standards include several wiring and signaling variants of the OSI physical layer. Systems communicating over ...
