Huawei S7700 Series Smart Routing Switches (2)

Huawei S7703, S7706, S7712 Routing Switches is high-end switch, they have below features:

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. S7700 switch can manage up to 1K APs and 16K users. It is the 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."
• The Service Chain feature virtualizes the value-added service processing capabilities, such as firewall, so that campus networks can utilize these capabilities in an undifferentiated manner. That is, these capabilities can be used without location constraint.

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, and is compatible with the currently used cards, helping enterprises maximize their ROI.
• The S7700 provides high-density 10GE ports and 100G ports, Each S7712 chassis can provide a maximum of 480 x 10GE ports as ES1D2X40SFC0-40-Port 10GBASE-X Interface Card (FC, SFP+) or 24 x 100GE ports, meeting the requirements of bandwidth consuming applications, such as multimedia conferencing and data access.
• 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's rack structure uses a passive backplane design. The S7700 provides redundant backup for key components, including MPUs, power supply units, and fans trays, 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. 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. 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.
