Introduction

Quidway NE5000E Terabit
Core Router
Exploiting the thinking derived from Fifth Generation router, NE5000E take use of two kinds of forwarding
engine, one based on ASIC and the other based on NP, to leverage the requirement from both
uncompromising performance and flexible service.
A single chassis supports the non-blocking, full-wire-speed switching of up to 64 10G-interfaces or 16
40G-interfaces in then near future. The throughput capacity can reach 2.56Tbps, and the forwarding
performance of the system can be 1600Mpps with single chassis.
NE5000E provides the abundant high-performance interfaces to meet the internetworking requirements.
It provides 16 Line Processing Units (LPU).
NE5000E has a wide LPU family: 1* 10GE port LPU, 1* 10G POS port LPU, 4*2.5G POS ports LPU,
4*10G POS ports LPU, 4*10GE ports LPU, high density GE (20/24/48) ports LPU and so on.
IPv4/IPv6 Dual Protocol Stacks
NE5000E supports bothIPv4 and IPV6 protocol stacks and can work in the IPv4/IPv6 dual-stack mode.
Product Features
Powerful Scalability
NE5000E supports maximal 64 chassis stack to scale the system capacity up to 160Tbps without
service interruption. It is characterized by:
NE5000E have three choices for the multi-chassis stack: back-to-back 2-chassis-system, 4-chas-
sis-system and 64-chassis-system.
Back-to-back 2-chassis system needn't additional fiber shelf for the interconnection which is nec-
essary for other else choice. This method support 2 chassis to comprise a routing gear. So back-
to-back is a relatively economic & simply method to scale the capacity.
4-chassis-system and 64-chassis-system respectively support maximal 4 and 64 chassis inter-
connection and additional fiber shelves are necessary for them. With them carrier can scale these
system seamlessly from 1 to 4 and from 5-64.
Terabit Capacity and 10G/40G interface

Provide all IPv6 features and solutions for smooth transition from IPv4 networks to IPv6 networks.
Support three IPv6 over IPv4 tunnel techniques: manually configured tunnel, automatic tunnel,
and 6to4 tunnel.
Superior QoS processing
NE5000E can effectively control Bandwidth, delay, jitter, and packet loss by its QoS features; the
buffering mechanism on both upstream and downstream results in a low packet drop rate. In addition,
NE5000E also features that:
MPLS QoS is independent of IP QoS by individual queuing management mechanisms.
PQ and WRR/WFQ not only guarantee the fair dispatching but also ensure that high-precedence
services are served first.
Three-stage switching fabric is based on the Combined Input and Output Queuing (CIOQ), which
guarantees the non-blocking switching.
Flow-based dispatching facilitates the MPLS TE and supports the Diff-Serv and Inter-Serv.
Four precedence queues per physical port prevent the high-precedence traffic from being interfered.
Independent Traffic Management processing module based on ASIC and NP provides the stable
QoS performance.
Security Guarantee
NE5000E takes multiple security measures to guard both the gear and the traffic through this gear.
The measures can prevent DOS attacks, illegal accesses, and control plane overload. The distributed
architecture separates the traffic plane from the control plane. And the security features include:
Supporting two kinds of user authentication modes for logging in: local authentication and RA-
DIUS/TACACS authentication;
Secure Shell (SSH) for the authentication and end-to-end encryption;
Integration with SSH based on Authentication, Authorization and Accounting (AAA);

The national backbone network applies the partial mash topology. It upstream connects to the
international egress, and downstream to junior provincial backbone networks. It also connects
with other ISP networks through NAPs. NE5000E can work as the core node of the national
backbone network because of its large capacity, high-density ports, and powerful routing and
high-speed forwarding capability.

This solution is applicable to establish, scale or reconstruct large ISP provincial backbone networks.
These ISPs have the Internet access services and cost advantages, as well as transmission
resources. In the case of transmission resources shortage, the link bandwidth can be reduced
accordingly without changing the network topology. The devices on the convergence layer or
above have the wire speed forwarding capability. The entire network supports MPLS VPN.
Application in the Provincial Backbone Network
As shown in Figure 1-3, the core layer of the provincial backbone network is composed of NE5000E
devices. The NE80/NE40 devices act as the city nodes, converging the traffic from the MAN,
leased line service, narrowband access, and Internet Data Center (IDC).

Figure 1-4 Application in an IPv6 backbone network
The IPv6 application on the backbone network does not impact the original IPv4 services such as
IPv4 forwarding and MPLS VPN. The application needs to solve two problems:
Interconnection between IPv6 islands
Interworking between IPv6 and IPv4 networks

PE/NAT-PT
NE5000E brings forward the following solutions based on IPv6 techniques:
All the routers on the backbone network support the IPv4/IPv6 dual-stack. In this case, IPv4 ser-
vices are forwarded over IPv4, while IPv6 services are forwarded over IPv6. Both of the problems
can be solved.
The interconnection between IPv6 islands can be implemented through L3 tunnels, manually con-
figured tunnels or 6to4 tunnels. The core router needs only to support the IPv4 forwarding. The
interworking between IPv6 and IPv4 networks can be implemented by configuring the NAT-PT on
gateways.
The interconnection between IPv6 islands can be implemented through MPLS L2 tunnels by ap-
plying such MPLS L2 VPN techniques as VPLS and CCC. The core router needs only to support
the MPLS forwarding. The interworking between IPv6 and IPv4 networks can be implemented by
configuring the NAT-PT on gateways.

Core Router
In this application NE5000E routers serve as the Provider�P� routers/nodes/devices in the net-
work core. For an multi-AS VPN application, NE5000E can also act as a Customer Edge (CE)
device in the case that it is an Autonomous System Boundary Router (ASBR). The NE80/40 rout-
ers serve as the Provider Edge (PE) devices, providing the NAT and the Internet access.
