Advanced, high-performance electronics with comprehensive scalability and management features offer cutting-edge advantages for enterprise campus networks and next-generation data centers.
Agile Switch, Enabling Networks to Be More Agile for Services
The S7700 series’ native ACs allow enterprises to build a wireless network without additional AC hardware. Each S7700 switch can manage 1K APs and 16K users. It is a core switch that provides T-bit AC capabilities, avoiding the performance bottleneck on independent AC devices. The native T-bit AC capabilities help organizations better cope with challenges in the high-speed wireless era.
The S7700 series’ unified user management function authenticates both wired and wireless users, ensuring a consistent user experience no matter whether they are connected to the network through wired or wireless access devices. The unified user management function supports various authentication methods, including 802.1x, MAC address, and Portal authentication, and is capable of managing users based on user groups, domains, and time ranges. These functions control user and service management and enable the transformation from device-centered management to user-centered management.
Super Virtual Fabric (SVF) technology can not only virtualize fixed-configuration switches into S7700 switch line cards but also virtualize APs as switch ports. With this virtualization technology, a physical network with core/aggregation switches, access switches, and APs can be virtualized into a “super switch”, offering the simplest network management solution.
Packet Conservation Algorithm for Internet (iPCA) changes the traditional method that uses simulated traffic for fault location. iPCA technology monitors network quality for any service flow at any network node, at any time, and without extra costs. It can detect temporary service interruptions within one second and can identify faulty ports accurately. This cutting-edge fault detection technology turns “extensive management” into “fine granular management.”
Powerful service processing capabilities

The S7700’s multi-service routing and switching platform meets requirements for service transmission at the access, aggregation, and core layers of enterprise networks. Wireless access, along with voice, video, and data services, helps enterprises build integrated full-service networks with high availability and low latency.
Distributed Layer 2/Layer 3 Multiprotocol Label Switching (MPLS) VPN functions, including MPLS, Virtual Private LAN Service (VPLS), Hierarchical VPLS (HVPLS), and VLL, implement 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 conferencing services.
Carrier-grade reliability and visual fault diagnostics
Huawei’s design ensures uptime performance of 99.999%. The S7700’s rack structure uses a passive backplane design. The S7700 provides redundant backup for key components, including Main Processing Units (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. Clustering provides the industry’s highest cluster bandwidth of 256 Gbit/s. Inter-chassis link aggregation can be used to improve link use efficiency and prevent single-point failures.
Service ports can be used as cluster ports, allowing connection of cluster members through optical fibers, substantially expanding the clustering distance.
The S7700 has a dedicated fault detection module that provides hardware-based Operation, Administration, and Maintenance (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 a Network Management System (NMS), which provides a graphical fault diagnosis interface and traverses all network elements and links automatically to help users quickly detect and locate faults.
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 prevents interruption of key services during software upgrades.
Enhanced QoS mechanism for responsive voice and video applications
The S7700’s Quality of Service (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 enterprise QoS requirements for a variety of services and user terminals.
The S7700 supports hardware-based low delay queues for multicast packets, ensuring that the video service can be processed with high priority and low delay. This feature guarantees the high quality of key enterprise services, such as video conferencing and surveillance.
Innovative priority scheduling algorithms optimize the QoS queue scheduling mechanism for voice and video services. This improved scheduling mechanism shortens VoIP service delays and eliminates video pixilation, improving user experience.
