A-5
T
Telnet
An application protocol of the TCP/IP stack that provides virtual terminal
services for a wide variety of remote systems.
Terminal
A device that is connected with other devices through the serial port. The
keyboard and the display have no disk drives.
Traffic policing
A process used to measure the actual traffic flow across a given connection and
compare it to the total admissible traffic flow for that connection. When the
traffic exceeds the agreed upon flow, some restrictions or penalties are taken to
protect the benefit and the network resource of the operator.
Traffic shaping
A flow control measure to shape the flow rate. It is often used to control the
flow in regular amounts to ensure that the traffic fits within the traffic for the
downstream router and avoids unnecessary discard and congestion.
Tunnel
Secure communication path between two peers in the VPN that protect the
internal information of the VPN from the interruption.
V
VPLS
Virtual Private LAN Segment.
VPN
Virtual Private Network. A new technology developed with the Internet to
provide an apparent single private network over a public network. "Virtual"
means that the network is a logical network.
VRP
Versatile Routing Platform. A versatile routing operating system platform
developed for all data communication products of Huawei. With the IP service
as its core, the VRP adopts the componentized architecture. The VRP realizes
rich functions and provides tailorability and scalability based on applications.
VRRP
Virtual Router Redundancy Protocol. An error tolerant protocol defined in RFC
2338. It forms a backup group for a group of routers in a LAN that functions as
a virtual router.
VTY
Virtual type terminal. A terminal line that is used to access a router through
Telnet.
W
WAN interface
Wide Area Network interface. An interface that can be a serial interface,
E1/CE1 interface, T1/CT1 interface, E2/CE3 interface, E3 interface, T3/CT3
interface, T3 interface, CPOS interface, POS interface or ATM interface. The
router can exchange data with the network device in the external network
through the WAN interface.
X
X.25
A protocol applied on the data link layer that defines how connections between
DTE and DCE are maintained for remote terminal access and computer
communications in PDNs.
XModem
A transmission protocol in the format of the binary code.
