Quidway Huawei NetEngine 80E
Introduction
The Quidway® NetEngine 80E core router ( NE80E for short) is the new generation high-end core router developed by Huawei Technologies Co., Ltd. Providing full line-rate 10G interface, the NE80E can be applied in the IP backbone network, Metro area network or as the core node in large networks with heavy traffic to bear multiple services. Adopting a series of advanced technologies such as three-stage switching fabric, network processors (NP) and ASIC Chipsets for forwarding engine, and the mature, stable VRP routing software of Huawei, the NE80E can provide high performance, preeminent scalability and high reliability, IPv4/v6 dual protocol stacks, superior QoS features and abundant security functionality. With excellent hardware and software architectures design, the NE80E can meet the availability requirements and multiservice demands of the carrier-class networks.
Product Features
2.1 10G Performance and Terabit Capacity
The NE80E has taken an advanced hardware forwarding technology. A single NE80E chassis can support nonblocking, full line-rate switching of up to 16 10G-interfaces, with a total interface capacity of 320G. The NE80E's switching capacity reaches 640G, while the forwarding capacity 400Mpps, and the backplane capacity 4T.
2.2 Carrier-Class Architecture Design
The NE80E chassis adopts carrier class design with hot swappable boards. The chassis dimensions are 442 mm x 600 mm x 1600 mm (width x depth x height). It can be mounted in an N68-22 cabinet or a 19” standard cabinet. The hardware structure of the NE80E has the following features in maintainability:
The backplane is installed from the rear of the chassis, which facilitates installation and maintenance.
There are two cable-management brackets respectively above and below the board cage, which facilitates the cable layout and board installation and maintenance. The fan modules can operate independently and support hot swap. Two fan modules provide the function of heat dissipation for two board cages.
The NE80E provides a powerful monitoring system. The Main Processing Unit (MPU) implements the management and maintenance for the whole system, including the boards, fans, Liquid Crystal Display (LCD) modules, and power distribution modules, etc.. With module-level shielding performance and a steel sheet for each panel, the NE80E realizes the Electromagnetic
Compatibility (EMC) isolation between boards.
2.3 High Reliability
NE80E can meet the high reliability requirements for the carrier-class and high-end applications with the following
features.
Adopting hot swappable boards, power modules and fans.
Providing redundant key modules, such as: Main Processing Unit (MPU, 1+1), Switch Fabric Unit (SFU, 3+1),
power supply, fan modules, bus, and clocks.
Adopting the distributed hardware forwarding.
Separating the control channel from the service channel to provide a non-blocking control channel.
Possessing system/board fault detection, LEDs, and NMS alarm function.
Applying the generic integrated NMS platform which is independently developed by Huawei.
Supporting protection mechanisms such as IP/MPLS fast rerouting, interface automatic protection switching (APS/
MSP), Virtual Routing Redundancy Protocol (VRRP), RPR automatic protection switching.
2.4 Uncompromising IPv4 and IPv6 Compatibility
The NE80E fully supports IPv4 and IPv6 dual protocols stacks. It can provide all IPv6 features, and so offers a good solution to smooth transition from IPv4 networks to IPv6 networks.
The NE80E supports three kinds of IPv6 over IPv4 tunnel techniques: manually configured tunnel, automatically configured tunnel, and 6to4 tunnel. The large-capacity routing table and forwarding table enables the NE80E to serve as the Virtual Private Network Provider Edge (VPN PE), and allows the future expansion of services.
The NE80E supports the distributed forwarding of both IPv4/IPv6 and Multi-Protocol Label Switching (MPLS). Due to its powerful routing capability, the NE80E can be applied in the Internet backbone network. IPv4 supports the routing table with a capacity of 3.2M routing entries, and IPv6 supports the routing table with a capacity of 2.6M routing entries. The NE80E supports such IPv4 dynamic routing protocols as Routing Information Protocol (RIP),
Open Shortest Path First (OSPF), Intermediate System-Intermediate System (IS-IS), Border Gateway Protocol (BGP) and multicast protocols. The NE80E supports such IPv6 dynamic routing protocols as BGP4+, RIPng, OSPFv3 and IS-ISv6.
2.5 Excellent QoS Mechanism
The NE80E provides excellent QoS scheduling and buffer mechanisms, including:
PQ and Weighted Round Robin (WRR) / Weighted Fair Queuing (WFQ): guarantees the fair dispatching and ensures that high-priority services are served first.
Three-stage switching network: is based on the Combined Input and Output Queuing (CIOQ) against Head of Line (HOL) congestion.
Flow-based dispatching: facilitates MPLS TE and supports the Diff-Serv and Inter-Serv.
Hardware-based QoS functions: guarantees line-rate forwarding while providing QoS services.
The QoS mechanism can meet the requirements of the IP Telecom Network (IPTN). It can guarantee the delay, jitter, bandwidth and packet drop ratio of different services. It also guarantees the launch of carrier-class services such as the Voice over IP (VoIP).
2.6 Comprehensive Security Design
The distributed design of the NE80E isolates the data plane from the control plane. This design allows the NE80E to offer industry-leading security features. With various security measures, the NE80E can prevent Denial-of-Service (DoS) attacks, illegal accesses, and overload of the control plane, and offer data protection to ISP networks and
terminal users.
The NE80E offers the following security features:
Two user authentication modes: local authentication and RADIUS authentication
