Features
The S8500 series adopts numerous industry-leading
features to realize the promise of top-ranking
services, performance and availability with investment
protection for enterprise and service provider
IP communication markets, including:
Advanced System Structure
The S8500 series introduces the distributed system
architecture and powerful ASIC chips for high-speed
routing, as well the Crossbar technologies for
packet switching, which greatly improve the forwarding
performance and expansion capabilities of the
routing switch. Embedded in the main control module,
the Crossbar switching fabric provides a switching
capacity up to 720 Gbps and can be set to work
in the active/standby or load-sharing mode by
software configuration. Through several 10 Gbps
buses, the interface module is connected to the
Crossbar switching networks on the two main control
modules realizing the hot backup of dual main
controls and dual switching networks in the real
sense and greatly improving the system reliability.
Adopting the advanced system ASIC chip design,
the longest routing prefix mode and the packet-bypacket
forwarding mode, the S8500 series can effectively
combat network viruses like Worm.Blaster, get
more applicable to large-scale networks with multiple
services and complex visit flows and match more
exactly the Ethernet MAN development trend, while
keeping the wire-speed performance and relying
on the low cost.
High Capacity, High-Density, Wire-Speed
Forwarding
The S8500 series can provide 1.8T backplane bandwidth,
720 Gbps switching capacity and 428 Mpps forwarding
capability to support ultimate 576 GE ports or
48 10GE ports totally. In addition, the S8500
series provides flexible interface choices from
10/100/1000 Megabit to 10 Gigabit Ethernet and
combined interface boards to satisfy the customer's
requirements for high density and high throughput.
Ideal for powerful hardware platform upgrade
capabilities, the S8500 series has reserved a
large number of bus interfaces on the backplane
for future system expansion. The system switching
capacity can be smoothly expanded to terabits
to meet the ever-increasing bandwidth needs and
user investment protection.
Carrier-Class Reliability Design
The S8500 series adopts distributed processing
structure to support dual main control switching
units with all interface modules and power supply
modules hot swappable and passive backplane design.
The power system has dual power inputs following
the 1+1 redundant hot backup mechanism. All the
reliability designs ensure the system to meet
strict requirements for carrier-class network
reliability (up to 99.999%).
MPLS Distributed Wire-speed Supported
The S8500 series provides hardware based Multi-protocol
Label Switching (MPLS) to enable VPN services
within the enterprise and facilitates smooth integration
with wire-speed service provider core infrastructures
and Metro Ethernet deployments. More than featuring
the configuration of VPN IPv4 address & distribution
VPN-IPv4 information by BGP, the S8500 series
offers the comprehensive MIB functions through
supervising VPN VRF, VPN Interface, VPN VRF BGP
configuration table and VPN VRF Route ,VPN VRF
Route Target table.
VLL & VPLS Layer 2 VPN Solutions
With the availability of MPLS enhanced interface
module, The S8500 series provides abundant distributed

Martini and Kompella mode with 4K VLL VC. In addition,
MPLS-VPLS has also been developed to provide centralized
VPLS processing capability, with 1K VPLS VSI and
MAC address 128/VSI; the processing capacity of
VPLS NP module reaches 3 Gbps and MAC table is
128K in total.
RPR Solution
The S8500 will offer 10G RPR interface module
in Q1/2006. The RPR (Resilient Packet Ring) technology
combines advantages of SDH network and Ethernet,
such as fault self-healing and cost-effectiveness
for SDH, high bandwidth, high flexibility and
expansibility for Ethernet. In addition, as RPR
is based on ring technology, it can provide advanced
features like highly efficient bandwidth management,
automatic topology discovery, QoS guarantee, etc.
Complete Security Mechanism
The S8500 series employs the 802.1x mode for
access user authentication, secure SNMPv3 NM protocol
and MD5 encrypted authentication of OSPFv2, RIPv2
and BGPv4 packets. By distinguishing different
