S
Service tracing
A method of service debugging, diagnosis and error detection that is mainly
used for service personnel to locate the fault in user access. The service tracing
can output the status change and the result of the protocol processing of the
specified user during the access to the terminal or the server for the reference
and analysis of the service personnel.
SSH
Secure Shell. A protocol that provides a secure connection to a router through a
TCP application.
Static ARP
A protocol that binds some IP addresses to a specified gateway. The packet of
these IP addresses must be forwarded through this gateway.
System environment
Basic parameters for running the MA5200G such as host name, language mode
and system time. After configuration, the system environment is coincident
with the actual environment.
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 carrier.
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 does not exceed 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.
