Telnet session
A Telnet Viewer session is a type of target device session in which the target device supports
Telnet and the DSView 3 software client connects directly to the target device using Telnet.
Telnet Viewer
This applet is a software component that provides the user interface needed to display a remote
target device through serial over IP sessions.
Tiered switch
A tiered switch is also known as a cascade switch. See the definition of cascade switch.
Unit
Unit is a generic term that refers to either a target device, managed appliance, blade chassis or
a component in a VMware environment. For example, the Unit List may contain both target
devices and managed appliances.
UDP (User Datagram Protocol)
UDP is a connectionless protocol that runs on top of IP networks like TCP. Unlike TCP/IP,
UDP/IP provides very few error recovery services, offering instead a direct way to send and
receive datagrams over an IP network. UDP is primarily used for broadcasting messages over
anetwork.
Video Viewer
The Video Viewer is a software component that provides the user interface needed to display a
remote target device through KVM over IP sessions.
VPN (Virtual Private Network)
VPN is a means of implementing a private network on a public network such as the Internet.
By encrypting data and assigning addresses, the impression is given to networks at each end of
the VPN that they are connected by a private physical network instead of across a
public network.
(WAN) Wide Area Network
WAN typically refers to a network that is distributed at multiple sites and connected by a
relatively slow link between the sites. The WAN is frequently implemented using a VPN on
the Internet.
(WAS) Web Application Server
WAS is software that runs on a server that is capable of executing web applications. The WAS
software typically contains or works with a web (HTTP) server.
(Webapp) Web Application
Webapps are groups of server-side Web resources that make up an interactive online
application. The web resources include Java servlets, JavaServer Pages
(JSPs), static
documents (such as HTML documents), and applets that can be deployed in a DSView 3
software client web browser. Web applications must run in the context of a web application
server such as the DSView 3 server.
