Queue Scheduling
Therefore, the NE80 can implement six groups of Per-Hop Behaviors (PHBs) defined in the
standard such as EF, AF1 to AF4 and BE as well as the other services.
The NE80 enables the network carriers to provide users with different QoS guarantee and
makes the Internet become the integrated network that carries data, voice and video services
simultaneously.
1.2.7 Excellent Security Mechanism
The NE80 provides the packet filtering/Access Control List (ACL) mechanism to prevent
illegal accesses and attacks of malicious packets.
The NE80 supports Unicast Reverse Path Forwarding (URPF) to prevent network attacks
based on the source address spoofing.
The NE80 supports port mirroring to analyze the traffic of a certain interface.
The NE80 provides multiple authentication methods (such as plain text authentication and
MD5) for key routing protocols, such as Open Shortest Path First (OSPF), Intermediate
System-Intermediate System (IS-IS), Routing Information Protocol (RIP) and Border
Gateway Protocol version 4 (BGP4).
The NE80 supports two user authentication modes: local authentication and Remote
Authentication Dial-In User Service (RADIUS) authentication to prevent illegal configuration
of the device.
The NE80 achieves the hardware-implemented NAT.
In addition, the NE80 provides abundant statistics including statistics of various types of
traffic, traffic sampling and NAT information statistics.
1.2.8 Practical NMS
Huawei Quidview NMS can manage Huawei's data communication products, supporting
Simple Network Management Protocol (SNMP) V1/V2c/V3 and the Client/Server model. It
can run on multiple operating systems, such as Windows NT/2000 and Unix (SUN, HP, and
IBM). The Quidview NMS can provide multi-language support and Graphic User Interface
(GUI).
The Quidview NMS can also be seamlessly integrated with the Huawei-developed network
management systems of other fixed network communication devices to achieve centralized
management of multiple devices. The Quidview NMS can also be integrated with the present
popular universal NMSs of the industry, such as HP OpenView, IBM NetView, What's up
Gold and SNMPc, to provide means of centralized management of devices from multiple
manufacturers.
The Quidview NMS provides the functions of managing the network topology (in real time),
faults, the performance, the configuration, device logs, security and users, QoS policy, and
VPN service. The Quidview NMS can also perform such functions as downloading, saving,
modifying and uploading NE80 configuration files and upgrading the NE80 software.
