A leased line is a private telecommunications circuit between two or more locations provided according to a commercial contract. It is sometimes also known as a private circuit, and as a data line in the UK. Typically, leased lines are used by businesses to connect geographically distant offices. Unlike traditional telephone lines in the public ...
A switch on the other hand provides a series of point-to-point circuits, via microsegmentation, which allows each client node to have a dedicated circuit and the added advantage of having full-duplex connections. From the OSI model's layer perspective, both switches and repeater hubs provide point-to-point connections on the physical layer.
In computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communication protocol between two routers directly without any host or any other networking in between. [ 1 ] It can provide loop detection, authentication, transmission encryption, [ 2 ] and data compression. PPP is used over many types of physical networks ...
Wide area network. A wide area network (WAN) is a telecommunications network that extends over a large geographic area. Wide area networks are often established with leased telecommunication circuits. [1] Businesses, as well as schools and government entities, use wide area networks to relay data to staff, students, clients, buyers and ...
Frame Relay is a standardized wide area network (WAN) technology that specifies the physical and data link layers of digital telecommunications channels using a packet switching methodology. Originally designed for transport across Integrated Services Digital Network (ISDN) infrastructure, it may be used today in the context of many other ...
Asynchronous Transfer Mode. Asynchronous Transfer Mode (ATM) is a telecommunications standard defined by the American National Standards Institute and International Telecommunication Union Telecommunication Standardization Sector (ITU-T, formerly CCITT) for digital transmission of multiple types of traffic. ATM was developed to meet the needs ...
MPLS VPN is a family of methods for using Multiprotocol Label Switching (MPLS) to create virtual private networks (VPNs). MPLS VPN is a flexible method to transport and route several types of network traffic using an MPLS backbone. There are three types of MPLS VPNs deployed in networks today: 1. Point-to-point (Pseudowire) 2.
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 ...
