Advanced Switching Architecture to Improve Network Expansibility

Huawei's advanced switching architecture permits rapid bandwidth expansion. The highly expansible backplane enables the port rates to be upgraded to 40 Gbit/s and 100 Gbit/s, and is compatible with the currently used cards, helping enterprises maximize their ROI.

Reliable Design to Ensure Consistent Service

The S9700 provides redundant backup for key components, including MPUs/SRUs, power supply units, and fans, all of which are hot swappable.

A cluster requires multiple switching processes across chassis, which reduces the switching efficiency. The S9700 implements the Cluster Switching System (CSS) function, solving this problem by switching fabrics. In this way, the switching fabrics of the switches in a cluster are connected. This method saves line card slots and provides 256 Gbit/s bandwidth, which is the highest rate in the industry.

The S9700 supports the iStack function, which allows switches that are far apart to form a stack. A port on the S9700 can be configured as a stack port using a command for flexible stack deployment. The distance between stacked switches is further increased when the switches are connected with optical fibers.

Full-Service Ethernet Switching Platform

The S9700 supports distributed Layer 2 and Layer 3 MPLS VPN functions, including MPLS, VPLS, HVPLS, and VLL, meeting the access requirements of enterprise VPNs.

The S9700 supports Layer 2 and Layer 3 multicast protocols, implements multicast replication among VLANs at the line rate, provides independent multicast QoS queues, and gives priority to services requiring minimal delay, such as voice and video services.

High-Performance IPv6 Service Support

Both the hardware platform and software platform of the S9700 support IPv6. The S9700 has earned the IPv6 Ready Phase 2 (Gold) designation.

The S9700 supports IPv4/IPv6 dual stack, various tunneling technologies, IPv6 static routes, RIPng, OSPFv3, BGP+, IS-ISv6, and IPv6 multicast to meet the requirements of independent IP networks and IPv4/IPv6 integrated networks.

Excellent Security Design

The S9700 comes equipped with an integrated firewall card. It supports virtual firewalls and NAT multi-instance, allowing multiple VPN customers to share the same firewall.

The S9700 performs authentication, authorization, and accounting (AAA) on access users according to pre-defined policies. In addition, the S9700 supports 802.1x, portal, guest VLAN, and dynamic user access authentication.

Wireless and Passive Integrated Access

The S9700 wireless AC card supports radio frequency management. The S9700 allows APs to automatically select their radio channels and power.

The S9700 wireless AC card supports Layer 2 and Layer 3 roaming and allows STAs to rapidly switch to the radio of another AP. It supports 1+1 and N+1 backup between ACs and load balancing among ACs, improving network reliability.

Innovative Energy Saving Design

The S9700 uses a rotating ventilation channel, improving heat dissipation efficiency. In addition, it uses a variable current chip to dynamically adjust the power according to traffic, reducing power consumption by 11%. Ports can hibernate when they do not transmit traffic or consume power.

The S9700 supports IEEE 802.3az Energy Efficient Ethernet, provides the low power idle mode for the line card PHY, and switches to a lower speed (power) PHY during low link utilization.

1 Application in Large-Scale Campus Networks

The S9700 can be used to build highly reliable, expansible, and manageable high-performance enterprise campus networks. The S9700 supports distributed IPv4/IPv6/MPLS wire-speed switching and provides high-density 10G data throughput for core and convergence nodes on enterprise campus networks. The S9700 supports the wireless AC module and can integrate it with the campus core device, saving on network investments. The S9700 also supports hardware CPU queues to protect the enterprise core against DDoS attacks and security threats.

2 Applications in Large-Scale Data Centers

The S9700 functions as a high-density 10G core and convergence node in large-scale data centers, helping enterprises build highly reliable, non-blocking, virtualized data center networks. The S9700 deploys various technologies to ensure uninterrupted services, including ISSU upgrades, IP FRR, hardware-level BFD, NSF, VRRP, and E-Trunk. Using the CSS and integrated load balancing solutions, the S9700 improves network efficiency and reduces network maintenance costs.
