S7700 Series Smarter Routing Switches
The S7700 series switches (S7700 for short) are high-end smart routing switches
designed for next-generation enterprise networks. The S7700 design is based on
Huawei's intelligent multi-layer switching technology to provide intelligent
service optimization methods, such as MPLS VPN, traffic analysis, comprehensive
QoS policies, controllable multicast, load balancing, and security, in addition
to high-performance Layer 2 to Layer 4 switching services.
The S7700 can
function either as an aggregation or core node on a campus network or in a data
center to provide integrated wireless access. The S7700 also offers voice,
video, and data services, helping enterprises build an integrated cost-effective
end-to-end network.

- 480*10GbE,
24*40GbE.
- Innovative Cluster Switching System(CSS).
- Hardware BFD/Ethernet
OAM.
- Left to rear air flow, high-density wiring.
Powerful Service Processing Capabilities
Huawei's advanced switching architecture permits rapid
bandwidth expansion. The highly expansible backplane enables ports to be
upgraded to a rate of 40 Gbit/s or 100 Gbit/s, and is compatible with the
currently used cards, helping enterprises maximize their ROI.
Each 7700 supports 480 10GE ports. The high density of 10GE
ports brings enterprise campus networks and data centers into the era of the
all-10GE core network.
The S7700's multi-service routing and switching platform meets
requirements for service bearing at the access layer, aggregation layer, and
core layer of enterprise networks. The S7700 provides wireless access along with
voice, video, and data services, helping enterprises build integrated
full-service networks with high availability and low latency.
The S7700 supports distributed Layer 2/Layer 3 MPLS VPN
functions, including MPLS, VPLS, HVPLS, and VLL, implementing VPN access for
enterprise users.
The S7700 supports various Layer 2 and Layer 3 multicast
protocols such as PIM SM, PIM DM, PIM SSM, MLD, and IGMP snooping. It can
provide enterprises with multi-terminal high definition video surveillance and
video conferencing services.
Carrier-Class Reliability and Visual Fault Diagnosis
Huawei's high reliability design ensures that the S7700 is
99.999% reliable. The S7700 provides redundant backup for key components,
including MPUs, power supply units, and fans, all of which are hot
swappable.
The S7700 innovatively implements the CSS function through
switch fabrics, and packets are only switched once when they are forwarded
between chassis. This addresses the problem of low switching efficiency caused
by multiple switching processes during inter-chassis forwarding in clusters
established using line cards. The cluster provides the industry's highest
cluster bandwidth 256 Gbit/s, In addition, inter-chassis link aggregation can be
used to improve link use efficiency and prevent single-point failures.
The S7700 can use service ports as cluster ports, so that
cluster members can be connected through optical fibers. This substantially
expands the clustering distance.
The S7700 has a dedicated fault detection subcard that
provides hardware-based OAM function conforming to IEEE 802.3ah, 802.1ag, and
ITU-Y.1731. Hardware-based OAM implements 3.3 ms fault detection and can check
session connectivity of all terminals in real time when a network fault occurs.
The S7700 can also work with an NMS. The NMS provides a graphical fault
diagnosis interface and traverses all network elements and links automatically
to help users detect and locate faults quickly.
The S7700 implements seamless switchover between the master
and slave MPUs and supports graceful restart to ensure nonstop forwarding. The
in-service software upgrade (ISSU) function of the S7700 prevents interruption
of key services during software upgrading.
Enhanced QoS Mechanism, Improving the Voice and Video
Experience
The S7700's QoS control mechanisms classify traffic based on
information from the link layer to the application layer. With advanced queue
scheduling and congestion control algorithms, the S7700 performs accurate
multi-level scheduling for data flows, satisfying enterprises' QoS requirements
for a variety of services and user terminals.
The S7700 supports hardware-based low delay queues for
multicast packets so that the video service can be processed with high priority
and low delay. This feature guarantees the high quality of key services in an
enterprise, such as video conference and surveillance.
The S7700 uses innovative priority scheduling algorithms to
optimize the QoS queue scheduling mechanism for voice and video services. The
improved scheduling mechanism shortens the delay of the VoIP service and
eliminates the pixelation effect in the video service, improving user
experience.
High-Performance IPv6 Service Processing, Resulting in a
Smooth Transition From IPv4 to IPv6
Both the hardware platform and software platform of the S7700
support IPv6. The S7700 has earned the IPv6 Ready Phase 2 (Gold)
designation.
The S7700 supports IPv4/IPv6 dual stack, various tunneling
technologies, IPv6 static routing, RIPng, OSPFv3, BGP+, IS-ISv6, and IPv6
multicast. These features meet the demand for IPv6 networking and combined IPv4
and IPv6 networking.
Superb Traffic Analysis Capability, Resulting in Real-Time
Network Performance Monitoring
The S7700 supports NetStream for the real-time collection and
analysis of network traffic statistics.
The S7700 supports the V5, V8, and V9 Netstream formats and
provides aggregation traffic templates to reduce the burden on the network
collector system. In addition, the S7700 supports real-time traffic collection,
dynamic report generation, traffic attribute analysis, and traffic exception
trap.
NetStream monitors network traffic in real time and analyzes
the device's throughput, providing data for network structure optimization and
capacity expansion.
Comprehensive Security Mechanisms, Protecting Enterprises
From Internal and External Security Threats
The S7700 comes equipped with an integrated firewall card and
supports virtual firewalls and NAT multi-instance, allowing multiple VPN
customers to share the same firewall. Its application-layer packet filtering
technology detects and filters application layer packets according to preset
rules.
The S7700 provides comprehensive NAC solutions for enterprise
networks. It supports MAC address authentication, Portal authentication, 802.1x
authentication, and DHCP snooping-triggered authentication. These authentication
methods ensure the security of various access modes, such as dumb terminal
access, mobile access, and centralized IP address allocation.
The S7700 is the industry leader in integrated security
solutions. It supports 1K CPU queues and uses a 2-level CPU protection
mechanism, separating the data plane from the control plane. Additionally, the
S7700 defends against DoS attacks, prevents unauthorized access, and prevents
control plane overloading.
Wireless AC Boards, Meeting Mobile Office
Requirements
The S7700 can use an access controller (AC) board to provide
radio frequency management functions. The AC board allows access points (APs) to
automatically select their radio channels and power. In an AP region, APs
automatically adjust radio channels and power in the event of signal
interference, enabling the receive signal strength indicator (RSSI) and
signal-to-noise ratio (SNR) to be continuously updated. The system can then
monitor the electromagnetic environment of every wireless user to improve
network availability.
The S7700's AC board supports multiple authentication methods,
including 802.1x authentication, MAC address authentication, Portal
authentication, and WAPI authentication. These authentication methods meet the
requirements of users who use different types of STAs and require different
security levels.
The S7700's AC board supports Layer 2 roaming, allowing STAs
to rapidly switch between APs. The S7700 supports 1+1 and N+1 cold backup
between ACs and load balancing among ACs, improving network reliability.
Innovative Energy-Saving Chips, Allowing for Intelligent
Power Consumption Control
The S7700 uses innovative energy-saving chips, which can
dynamically adjust power on all ports based on traffic volume. An idle port
enters a sleep mode to reduce power consumption.
The S7700 supports Power over Ethernet (PoE) and uses
different energy management modes according to the powered device (PD) type,
ensuring flexible energy management.
The S7700 supports IEEE 802.3az Energy Efficient Ethernet and
provides the low power idle mode for the PHY line card. If the link utilization
is low, the S7700 switches to a lower speed or power PHY to reduce power
consumption.
