466 DSView Installer/User Guide
On-Screen Configuration and Activity Reporting (OSCAR)
A tool that is built in to Avocent appliances that allows a DSView user connected to the local KVM
port to view and change settings in a DSR switch or CPS appliance. OSCAR also allows a local
user to connect to target devices.
Point to Point Protocol (PPP)
A set of industry-standard framing and authentication protocols included with Windows NT
Remote Access Service to ensure interoperability with third-party remote access software. PPP
negotiates configuration parameters for multiple layers of the OSI (Open Systems Interconnection)
model.
Secure Hypertext Transfer Protocol (HTTPS)
An extension to the HTTP protocol that supports sending data securely over the WWW.
Secure Sockets Layer (SSL)
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.
Serial Session
A type of target device session in which the target device contains a serial connection (typically a
Linux server TTY port or a Router) and is connected through a CPS appliance. A Telnet/SSH
applet connection exists between the DSView Client and the CPS appliance. The CPS appliance
converts the Telnet information to serial information.
Server
A computer or device on a network that manages network resources. For example:
• A file server is a computer and storage device dedicated to storing files. Any user on the net-
work can store files on the server.
• A print server is a computer that manages one or more printers.
• A network server is a computer that manages network traffic.
• A database server is a computer system that processes database queries.
Servers are often dedicated, meaning that they perform no other tasks besides their server tasks.
However, on multiprocessing operating systems, a single computer can execute several programs at
once. In this case, a server may refer to the program that is managing resources rather than the
entire computer.
Session
When used alone, a session refers to a target device session. See the definition of Target Device
Session for details
