Routing Switches

The Quidway S8500 Series 10G multi-

service core routing switch (referred to as

the S8500 Series Switch hereinafter) is a

new-generation high performance switch. It

is extensively applied as the core layer of

e-government networks, campus networks,

education MANs, and enterprise networks,

and the core layer and aggregation layer of

carriers’ IP MANs.

Based on the 10G platform, it supports the

new-generation high-performance 10Gbps

interface and can provide super high-

speed links for MANs, campus networks

and data centers to construct end-to-end

Ethernet featuring low cost, high

performance and capabilities to support

abundant services. It provides L2 and L3

wire-speed forwarding and MPLS

distributed wire-speed forwarding by high

performance, large capacity, high density

and modularization design. It also

provides rich service functions, powerful

QoS guarantee, complete security

management mechanism and carrier-class

high reliability design to fully satisfy the

requirements of high-end users for multiple

services, high reliability and large capacity

and large bandwidth.

Key Benefits

Advanced System Structure

Distributed structure design is adopted for

the S8500 Series Switch, powerful ASIC

chips are used for high-speed routing and

Crossbar technologies are adopted for

high-speed packet switching, all of which

greatly improve forwarding performance

and expansion capabilities of the routing

switch. Built in the main control board

without taking up the equipment slot, the

Crossbar switching chip provides a

switching capacity up to 720G and can be

set to work in the active/standby or load-

sharing mode via software configuration.

The interface board is connected to the

Crossbar switching networks on the two

main control boards via several 10G

buses, thus realizing the hot back-up of

dual main controls and dual switching

networks in the real sense and greatly

improving the system reliability.

The new-generation high performance

ASIC chip design, the routing mode of

longest prefix matching and the packet-by-

packet forwarding mode are adopted for

the S8500 Series Switch. As the design

technologies develop and the techniques

and integration improve, the ASIC chip can

implement the wire-speed longest prefix

matching based on the existing low cost,

and remove the defects of former ASIC

chips that can only process the precise

matching table and can realize the longest

prefix matching table function only via

software. Thus, while keeping the wire-

speed performance and relying on the low

cost, the S8500 Series Switch

revolutionarily removes the defects of

traditional switches, and effectively

combats network viruses like Worm.

Blaster. It is more applicable to large-scale

networks with multiple services and

complex visit flows and caters more to the

Ethernet MAN development.

Large Capacity, High-density

Wire-speed Switching

The Quidway S8512 switch can provide a

backplane bandwidth of 1.8T, a switching

capacity of 720Gbps and forwarding

capabilities of 428Mpps. High-density

interface boards can be provided for the

switch to support wire-speed forwarding. In

addition, while keeping the wire-speed

forwarding performance, the switch

supports different high-density interface

boards and combined interface boards to

satisfy the core layer’s requirements for

high density and high throughput.

It also has powerful hardware platform

upgrade capabilities. A large number of

high speed circuit are reserved on the

backplane for future system expansion. The

system switching capacity can be smoothly

expanded to terabits to meet ever-

increasing bandwidth needs and give

added protection to users’ investments.

Support of New-generation 10G

Interfaces

The new-generation 10G Ethernet

interface provides richer bandwidths and

powerful processing capabilities while

preserving the compatibility and simple

usage of Ethernet for easy upgrade.

Meanwhile, the 10G Ethernet provides

pertinent solutions for MAN and WAN

applications to simplify network

architecture and reduce network

construction costs.

The new-generation 10G Ethernet

provided by the S8500 Series Switch

overcomes a number of limitations of the

earlier 10G Ethernet, provides powerful

QoS guarantee based on wire-speed

forwarding, and supports rich features

such as ACL, strategic routing and

security. It can support wire-speed MPLS

forwarding, provide better IP VPN services

and transparent LAN services.

In addition to standard LAN interfaces, the

S8500 Series Switch provides GE

interfaces that employ wavelength division

multiplexing technologies to greatly raise

the flexibility of user networking.

MPLS Distributed Wire-speed

Support

The S8500 Series Switch complies with

the design concept that attaches

importance to both services and

performance. On the one hand, the

bandwidth and network scale increase

push the performance improvement and

capacity increase of the core routing

switch. On the other hand, the service

development requires the core switch be

more intelligent and have more powerful

service provision capabilities. The S8500

Series Switch adopts the powerful ASIC

chip to realize the MPLS distributed wire-

speed forwarding.

Carrier-class Design Reliability

Distributed structure is adopted for the

S8500 Series Switch to support dual main

control switching boards. The switch

supports passive backplane design and all

the boards support hot swap. The 1+1

redundant hot back-up mechanism is

adopted for the power supply system and

dual power inputs are supported. The

switch supports the STP/RSTP/MSTP and

VRRP protocols and can meet strict

requirements for carrier-class network

reliability (up to 99.999%).

Complete Security Mechanism

The S8500 Series Switch supports clear

text and MD5 encrypted text authentication

of OSPF, RIP v2 and BGP v4 packets. It

adopts the 802.1x mode for access user

authentication, and supports secure

SNMPv3 protocol, configuration security

for user authentication. Users of different

levels have different configuration rights

and two user authentication modes are

provided: local authentication and RADIUS

authentication.

The S8500 Series Switch also supports the

standard Radius protocol, provides the

Radius+ function, and supports the

HCBM™ (Huawei controllable constrained

multicast) function.
