In this case, the NE80 may reduce the levels of the network construction to achieve the
flattened network, which improves the service quality and optimizes the network architecture.
1.2.2 Line-Speed Forwarding
The NE80 supports the IPv4/MPLS distributed forwarding at the line speed. Thus the NE80
can meet the bandwidth requirements when it is used as the Point of Presence (POP), the
convergence layer, or the switching node on the backbone networks.
1.2.3 Multiple Interfaces
At present, the NE80 provides the Fast Ethernet (FE) interface, Gigabit Ethernet (GE)
interface, E1/cE1 interface, E3 interface, T3 interface, Packet over SDH/SONET (POS)
interface, channelized POS (cPOS) interface, Asynchronous Transfer Mode (ATM) interface,
and RPR interface with high interface density. Users can select the cards flexibly as required
to meet the requirements for different networking solutions and network expansion.
1.2.4 Carrier-Class Availability
The key parts of the NE80 adopt redundant hot backup design, including system control, data
exchange, route processing system, internal management bus and power supply. All the
components are hot swappable. Thus, the router can meet the high reliability requirement
when it is used as the POP, the convergence layer, or the switching node on the backbone
networks
1.2.5 Rich Services
The IP multicast forwarding feature provides the foundation for carriers to carry on various
network voice and video services (Web TV, E-learning, telemedicine and video conference).
With the rich routing features, the router is adaptable to complex environments.
The policy service mechanism enables the system to have powerful performance optimization
capability, satisfactory attack defense capability and QoS guarantee while ensuring the line
rate processing and forwarding capability.
The application of the MPLS VPN service guarantees the delivery of services of carriers
using networks more economically and rationally with no need to increase the bandwidth.
The application of the NAT service supports addressing with public and private network
addresses mixed in the MAN to save IP addresses. In this way, the shortage of
public IP addresses can be solved.
Through Dynamic Host Configuration Protocol (DHCP) Relay and built-in DHCP Server, IP
addresses can be dynamically assigned to users and be managed.
1.2.6 Perfect Diff-Serv/QoS
The NE80 realizes the QoS feature when carrying the integrated service including the
real-time service. In particular, the NE80 provides various standard-based supports to
Diff-Serv, including:
z
Traffic classification
z
Traffic policing
