SPC power control device
The SPC power control device is an Avocent cascade device that allows the remote controlling
of target device power using a serial connection.
SSL (Secure Sockets Layer)
SSL is a protocol that supplies secure data communication through data encryption and
decryption. SSL enables private communications over networks by using a combination of
public key cryptography and bulk data encryption.
Target device
A target device includes a wide range of data center components such as servers and routers
that an administrator is able to virtually manage through the DSView management software.
Target device session
A target device session is a connection through a KVM, serial, Telnet or web browser. Target
device sessions do not include power management functionality.
TCP/IP (Transmission Control Protocol)
TCP is one of the main protocols in TCP/IP networks. The IP protocol deals only with packets.
TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees
delivery of data and that packets will be delivered in the same order in which they were sent.
Telnet session
A Telnet session is a type of target device session in which the target device supports Telnet
and the DSView 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 or a managed appliance. 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)
