802.1Q in 802.1Q (QinQ), also called Stacked VLAN or Double VLAN,
is extended from 802.1Q and defined by IEEE 802.1ad recommendation.
This VLAN feature allows the equipment to add a VLAN tag to a tagged
packet. The implementation of QinQ is to add a public VLAN tag to a
packet with a private VLAN tag, making the packet encapsulated with
two layers of VLAN tags. The packet is forwarded over the ISP's
backbone network based on the public VLAN tag and the private VLAN
tag is transmitted as the data part of the packet. In this way, the QinQ
feature enables the transmission of the private VLANs to the peer end
transparently. There are two QinQ types: basic QinQ and selective
QinQ.
A network security mechanism, used to solve problems of network delay
and congestion. When the network is overloaded or congested, QoS can
ensure that packets of important services are not delayed or discarded
and the network runs high efficiently. Depending on the specific system
and service, it may relate to jitter, delay, packet loss ratio, bit error ratio,
and signal-to-noise ratio.
Evolution of the Spanning Tree Protocol (STP), which provides
improvements in the speed of convergence for bridged networks
RADIUS refers to a protocol used to authenticate and account users in
the network. RADIUS works in client/server mode. The RADIUS server
is responsible for receiving users' connection requests, authenticating
users, and replying configurations required by all clients to provide
services for users.
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.
SNTP is mainly used for synchronizing time of devices in the network.
In this fiber, single-mode optical signals are transmitted.
