二、 Product Features
Innovative VSS virtualization cluster switching technology
      Support VSS (Virtual Switch System) virtualization cluster switching technology, which can virtualize multiple physical devices into a logical device. The performance, reliability, and management of its virtual system are unparalleled compared to independent physical devices.
       Doubling performance: Virtualization systems can fully utilize every link between physical devices, avoiding the blocking of links by traditional networking model spanning tree protocols, making full use of resources, doubling performance, and maximizing the protection of existing link investments.
       High reliability: Based on advanced distributed processing technology, efficient cross physical device link aggregation function is used to achieve the separation of logical control plane, business control plane, and business data plane, providing uninterrupted three-layer routing forwarding, avoiding business interruption caused by single point of failure, and greatly improving the reliability of virtual systems.
       Easy to manage: The entire virtual system achieves unified management of a single IP address, and the actual physical devices are transparent to users, simplifying the management of network devices and network topology, greatly improving network operation efficiency, and effectively reducing operation and maintenance costs.
Industrial grade Ethernet ring network function, zero latency, zero packet loss
       Supports industrial grade Ethernet ring protection protocol, with a protection switching time of less than 50ms, and can achieve high reliability requirements with zero packet loss.
A-series Carrier Ethernet Switches 
       Supports carrier grade Ethernet ring protection protocol with a protection switching time of less than 50ms; also supports STP/RSTP/MSTP protocol, dual uplink primary and backup link protection, LACP link aggregation, and other simple and efficient redundancy protection mechanisms to meet the high reliability requirements of carrier grade.
       A comprehensive Ethernet OAM mechanism that enables rapid detection and localization of faults through real-time monitoring of network operation status.
        Powerful ACL function, supporting physical port based VLAN、MAC、IP、 The access and control of L2~L7 layer data such as protocol port numbers provide users with flexible and diverse policy control methods.
        Support ISSU (In Service Software Upgrade) business uninterrupted system upgrade, ensuring uninterrupted forwarding of user data during system upgrade.
        Support rich layer 2 multicast functions, including IGMP Snooping, user quick departure mechanism, and cross VLAN multicast replication function.
Operational level QoS strategy
        Support the classification function of complex flows based on VLAN, MAC, source address, destination address, IP protocol, priority, etc., and support the re labeling of priority, providing a reliable and effective means for users to optimize their business.
         Provide flexible bandwidth control strategies, support port based or flow based speed limiting functions, ensure line speed forwarding at each port, and effectively ensure the quality of high-quality network services such as voice, video, and data.
         Each port hardware supports 8 priority queues.
         Support multiple queue scheduling algorithms such as SP, WRR, or SP+WRR.
Comprehensive IPv6 solution
        Fully supports the IPv6 protocol family, including IPv6 neighbor discovery, ICMPv6, Path MTU discovery, and other IPv6 features.
        Support IPv6 based Ping, Traceroute, Telnet, SSH, ACL, etc., to meet the needs of pure IPv6 network device management and business control.
Perfect security mechanism
       Device level security protection: Advanced hardware architecture design, hardware implementation of hierarchical scheduling and protection of packets, supporting prevention of DoS, TCP SYN Flood, UDP Flood, broadcast storm, high traffic and other attacks on devices; Support command line hierarchical protection, with different levels of users having different management permissions;
       Complete security authentication mechanism: Supports IEEE 802.1x, Radius, BDTacacs+, etc., providing users with a comprehensive security authentication mechanism.
        Support the suppression function of broadcast, multicast, and unknown unicast messages to ensure the normal operation of devices under harsh network conditions.
         A comprehensive loop detection mechanism can ensure the stable operation of the network for a long time.
         Provide port isolation within the same VLAN, as well as security features such as DHCP Snooping, IP+MAC+port binding, further ensuring user data security.
Flexible and convenient management and maintenance
           Supports multiple management methods such as Console, Telnet, SSH, etc.
           Support WEB management, which is simpler and more efficient, and easier for engineering and maintenance personnel to install and debug.
            Supports TFTP file upload and download management.
            Support ISSU (In Service Software Upgrade) business without interrupting system upgrades.
            Supports standard SNMP protocol and, in conjunction with the "NMS" intelligent network management platform, can achieve functions such as automatic device discovery, network topology management, device configuration management, performance data statistical analysis, and fault management, simplifying network management and providing users with a brand new user experience.
