Huawei CloudCampus S5720-HI Series Campus Switches New!
Huawei’s S5720-HI series switches are advanced Gigabit Ethernet switches that provide rich agile features. The switches are developed based on Huawei Versatile Routing Platform (VRP) and use the fully programmable structure to implement software definition and service change on demand. With services and network convergence as the core, the switches provide the ubiquitous service function to ensure consistent user experience. The Super Virtual Fabric (SVF) function virtualizes the entire network into one device. In addition, the switches support flexible Ethernet networking, comprehensive VPN tunnel solutions, various security control methods, intelligent deployment, and simple operation and maintenance. The S5720-HI switches are the best choices for the branches of high-quality large- and middle-sized campus networks, the core layer of small-sized campus networks, and the access layer of data center networks.
Enabling networks to be more agile for services
The high-speed Ethernet Network Processor (ENP) embedded in the S5720-HI is tailored for Ethernet. The chip’s flexible packet processing and traffic control capabilities can meet current and future service requirements, helping build a highly scalable network.
In addition to capabilities of traditional switches, the S5720-HI provides fully programmable open interfaces and supports user-defined forwarding behaviours. Enterprises can use the open interfaces to develop new protocols and functions independently or jointly with equipment vendors to build campus networks meeting their own needs.
The ENP has a fully programmable architecture, on which enterprises can define their own forwarding models, forwarding behaviors, and lookup algorithms. Microcode programmability makes it possible to provide new services within six months, without the need of replacing the hardware. In contrast, traditional ASIC chips use a fixed forwarding architecture and follow a fixed forwarding process. For this reason, new services cannot be provisioned until new hardware is developed to support the services one to three years later.
Delivering abundant services more agilely
The S5720-HI integrates the AC function, so customers do not need to buy independent AC devices or hardware components. An S5720-HI switch can manage 1K APs and 16K users, adapting to the fast growth of wireless services.
With the unified user management function, the S5720-HI 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 visualize user and service management and boost the transformation from device-centric management to user-centric management.
The S5720-HI provides excellent quality of service (QoS) capabilities and supports queue scheduling and congestion control algorithms. Additionally, it adopts innovative priority queuing and multi-level scheduling mechanisms to implement fine-grained scheduling of data flows, meeting service quality requirements of different user terminals and services.
Providing fine granular network management more agilely
The S5720-HI uses the Packet Conservation Algorithm for Internet (iPCA) technology that changes the traditional method of using simulated traffic for fault location. iPCA technology can monitor network quality for any service flow anywhere and anytime, without extra costs. It can detect temporary service interruptions in a very short time and can identify faulty ports accurately. This cutting-edge fault detection technology turns “extensive management” to “fine granular management.”
The S5720-HI supports Two-Way Active Measurement Protocol (TWAMP) to accurately check any IP link and obtain the entire network’s IP performance. This protocol eliminates the need of using a dedicated probe or a proprietary protocol.
The S5720-HI supports SVF and functions as a parent switch. With this virtualization technology, a physical network with the “Small-sized core/aggregation switches + Access switches + APs” structure can be virtualized into a “super switch”, offering the industry’s simplest network management solution.
With the Easy Deploy function, the S5720-HI manages access switches in a similar way an AC manages APs. In deployment, access switches and APs can go online with zero-touch configuration. In the Easy Deploy solution, the Commander collects topology information about the connected clients and stores the clients’ startup information based on the topology. Clients can be replaced with zero-touch configuration. The Commander can deliver configurations and scripts to clients in batches and query the delivery results. In addition, the Commander can collect and display information about power consumption on the entire network.
Comprehensive VPN technologies
The S5720-HI supports the MPLS function, and can be used as access devices of high-quality enterprise leased line. The S5720-HI allows users in different VPNs to connect to the same switch and isolates users through multi-instance routing. Users in multiple VPNs connect to a provider edge (PE) device through the same physical port on the switch, which reduces the cost on VPN network deployment.
Flexible Ethernet networking
In addition to traditional Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), and Multiple Spanning Tree Protocol (MSTP), the S5720-HI supports Huawei-developed Smart Ethernet Protection (SEP) technology and the latest Ethernet Ring Protection Switching (ERPS) standard. SEP is a ring protection protocol specific to the Ethernet link layer, and applies to various ring network topologies, such as open ring topology, closed ring topology, and cascading ring topology. This protocol is reliable, easy to maintain, and implements fast protection switching within 50 ms. ERPS is defined in ITU-T G.8032. It implements millisecond-level protection switching based on traditional Ethernet MAC and bridging functions.
The S5720-HI supports Smart Link and Virtual Router Redundancy Protocol (VRRP), which implement backup of uplinks. One S5720-HI switch can connect to multiple aggregation switches through multiple links, significantly improving reliability of access devices.
The S5720-HI has large entry sizes and buffers, coping with the fast growth of data volume in the big data era. With the support for 128K MAC addresses, 1M FIB entries, and 200 ms buffering on each port, the S5720-HI meets the requirements of educational networks and metro area networks and allows the access of a large number of terminals. The S5720-HI is the bes
