S
Simple Network
Management
Protocol (SNMP)
A network management protocol defined by Internet Engineering
Task Force (IETF) used to manage devices in the Internet. SNMP
can make the network management system to remotely manage all
network devices that support SNMP, including monitoring network
status, modifying network device configurations, and receiving
network event alarms. At present, SNMP is the most widely-used
network management protocol in the TCP/IP network.
Simple Network
Time Protocol
(SNTP)
SNTP is mainly used for synchronizing time of devices in the
network.
V
Virtual Local Area
Network (VLAN)
VLAN is a protocol proposed to solve broadcast and security issues
for Ethernet. It divides devices in a LAN into different segments
logically rather than physically, thus implementing multiple virtual
work groups which are based on Layer 2 isolation and do not affect
each other.
Virtual Private
Network (VPN)
Network scheme in which portions of a network are connected via
the Internet, but information sent across the Internet is encrypted.
The result is a virtual network that is also part of a larger network
entity. This enables corporations to provide telecommuters and
mobile professionals with local access to their corporate network or
to another ISP network. VPNs are possible because of technologies
and standards such as tunneling, screening, encryption, and IPsec.
