virtual connection
A technique that ensures that a network delivers packets to the correct
recipient in the same order as during submission.
virtual leased line
A VLL is a type of VPN in which IP is transported in a point-to-point
manner. CPE devices connect through nodes that connect to an IP tunnel.
virtual private LAN service
A VPLS is a type of VPN in which a number of sites are connected in a
single bridged domain over an IP/MPLS network. Although the services
may be from different locations, in a VPLS, they appear to be on the same
LAN.
virtual private network
A private network within a public network that takes advantage of the
economies of scale and management of large networks. VPNs are used by
enterprises to create WANs that span large geographic areas, to provide a
site-to-site connection between branch offices, and to allow mobile users to
dial up their company LANs.
When implemented with Layer 2 interfaces, this service is called VPLS.
When implemented with Layer 3 interfaces, this service is called an IP-VPN
wide-area network
A geographically dispersed, long-haul telecommunications network that
usually consists of backbone links. A WAN may be privately owned or
leased. The term usually connotes the inclusion of public networks that are
highly regulated, and provide superior reliability and resilience.
Windows are forms, panels of information, equipment drawings, or graphics
that appear on a screen. Windows commonly allow a user to input data and
initiate functions but some windows simply display information.
