Site
A site is a location that contains a managed appliance, DSView 3 software server or both.
SNMP (Simple Network Management Protocol)
SNMP is a set of protocols for managing complex networks. SNMP works by sending
messages to different parts of a network. SNMP-compliant devices, called agents, store data
about themselves in MIBs and return this data to the SNMP requesters.
SNMP manager
The SNMP manager is an optional component (outside of the DSView 3 software system) that
enables the monitoring of many cross-platform devices using SNMP information. SNMP
managers are also called network management systems (NMS).
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 3 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 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 or a managed appliance. For example,
the Unit List may contain both target devices and managed appliances.
