Quidway S9300 Series Ethernet Aggregation Switch

Overview

The S9300 is a high-end Ethernet aggregation switch developed by Huawei for the service-focused network. The S9300 adopts the intelligent multi-layer switching technology of Huawei. Besides the stable, reliable, and secure Layer 2/Layer 3 switching services, the S9300 provides the intelligent services such as service flow analysis, complete QoS policies, and controllable multicast. In addition, the S9300 provides high extensibility and reliability. Therefore, it can be widely used on the IP MANs of carriers, WANs and MANs of enterprises, egress, core layer, and convergence layer of enterprise intranets, desktop access with high-density GE interface cards, and data centers. The S9300 helps carriers and enterprises establish the service-focused network platforms and provide end-to-end routing and switching network services.

The S9300 has three types, which respectively provide 5 slots, 8 slots, and 14 slots. It has extensible switching capability and port density. The three types of S9300s use universal modules and components. This not only ensures the extensibility of the equipment, but also protects the investments of carriers. In addition, the S9300 adopts various innovative energy saving technologies, which greatly reduce the energy consumption and noise of the equipment without affecting the performance and stability of the system. By developing the S9300, Huawei can provide solutions for sustainable development of networks.

Product Characteristics

Innovative Triple-Plane Design

Based on the traditional data forwarding plane and control plane, the S9300 realizes a triple-plane design by adding an independent environment monitoring plane. The S9300 uses an innovative environment monitoring board to manage and monitor the boards, fans, and power modules. The environment monitoring board uses an independent central control chip, whose intelligent property is possessed by Huawei, to implement hardware-based power-saving functions such as dynamic power adjustment by traffic, separate fan control, intelligent fan speed adjustment, and port hibernation. The system performance is greatly improved and the power consumption of the entire equipment is reduced. Working with the network management system, the environment monitoring board provides a visual management environment for maintaining the S9300.

Versatile Multiservice Ethernet Switching Platform

The S9300 has the industry-leading performance, high port density, and high availability. It fully supports services, including:

• The entire chassis supports a maximum of 576 GE ports or 144 10GE ports. It adopts the industry-leading process design, optimized dimensions, and two-side cabling. The cabinet of the S9300 supports high port density: a maximum of 1728 GE ports or 432 10GE ports.
• The S9300 can aggregate traffic of DSLAMs and implement uniform access through Ethernet interfaces. Thus, user access can be implemented through optical fibers. With the L2/L3 MPLS VPN functions, the S9300 supports the MPLS, VPLS, HVPLS, and VLL. Therefore, the S9300 can meet the access requirements of VPN leased line for VIP customers and enterprise VPN.
• The S9300 has a capability to copy multicast packets between VLANs at the line speed on a full-load interface. This enables access of a large number of IPTV users. Through L2 and L3 multicast protocol, the S9300 can function as the multicast replication point and control point to provide IP multicast video and audio services.
• The L3 multiprotocol feature meets the requirements of traditional networks. It supports the large routing tables of enterprise networks and carrier-class networks. The S9300 supports IPv6 and provides smooth migration solution from IPv4 to IPv6 on the networks.
• The system can be expanded to support various clock solutions, including the synchronization Ethernet clock and clock synchronization defined in IEEE 1588.
• The S9300 supports PoE, which meets the requirement of Ethernet powering.

High Availability and Network Extensibility

• The availability of the S9300 is 99.999%, which meets the requirement of carrier-class operation. The key components of the S9300 include switching routing unit, power modules, and fans, which support hot swapping. The S9300 applies distributed hardware-based forwarding, and separates the control plane from the service plane.
• The service traffic can be switched between the active components and standby components without rebooting the equipment. In later versions, the S9300 will support the smooth upgrade of ISSU service to provide an application-service integrated network. This can reduce the interruption of key services.
• The S9300 supports the link aggregation feature defined in IEEE 802.3ad, the IEEE 802.1s/w standard, and the VRRP protocols. In addition, it supports various millisecond switchover technologies, such as RRPP, Smart Link, IP FRR, and TE FRR. The reliability of data transmission is improved.
• The S9300 provides 3.3 ms hardware-based Ethernet OAM function, which can quickly detect and locate faults. By using the Ethernet OAM technology and switchover technologies, the S9300 can provide millisecond protection for networks.

Smooth Expansion

• The S9300 uses various service boards and flexible service unit. In later versions, the S9300 will support firewall, IPSec, IDS, Netstream and NAT.
• As a new generation Ethernet aggregation platform, the S9300 meets the bandwidth requirement of the metro backbone network and large-capacity Internet data center (IDC). Each slot of the S9300 supports a 12x10GE wire-speed line card and the entire chassis provides a switching capacity of 2 Tbit/s to ensure the access to the IDC and high-bandwidth services such as IPTV. The system reserves switching capacities for future upgrade and can be expanded to provide 100GE switching capacity in the future.
• The switching capacity of the S9300 can be expanded to 3.84 Tbit/s and the forwarding capability of each slot can be expended to 480 Gbit/s. This meets the bandwidth requirements in the future 3-5 years. The S9300 can expand bandwidth smoothly.

Six Innovations to Save Power

As a new generation switch, the S9300 adopts the industry-leading technologies. It has large forwarding capacity and uses the energy saving schemes. The power consumption of the equipment and the equipment room is reduced and the cost on network maintenance is also reduced.

• Environment-friendly design: The S9300 uses an intelligent chip to adjust the equipment power according to the traffic, which can reduce equipment power 8%.
• Revolving air flow: Revolving air flow of the S9300 not only improves heat dissipation of the equipment, which can reduce equipment power 3%, but also facilitates six times cable-layout than traditional switch in one cabinet.
• On-demand configuration of the power supply: The power supply can be configured on demand to reduce the investment in the early stage and lower the power consumption 10%.
• Fan flexible controlling by position: Fans of high-power line cards and low-power line cards are controlled separately, which can reduce noise 10% and save power.
• Intelligent fuzzy fan speed-adaptation: The rotation speed of fans can be adjusted flexibly according to the temperature of key components free from temperature disturbance. This technology reduces equipment power 3% and extends the lifetime of fans.
• Port hibernation: The port hibernation technology enables the S9300 to adjust the output power according to the traffic on a port, thus saving power 6% without packet loss.
