Quhui.com Quidway MA5200G has the following specifications: project MA5200G-8 MA5200G-4 MA5200G-2 integrated chassis structure support 19 inch standard rack; Using network processor to realize high performance hardware forwarding. Overall dimensions (mm) width x depth x height 482.6× 420× 797.318u482.6× 420× 352.88u482.6× 420× 219.55u backplane capacity 256Gbps 256Gbps switching capacity (non-blocking switching, double backup) Double backup) HWTACACS user billing protocol RADIUS, HWTACACS, COPS user authorization protocol RADIUS, HWTACACS, COPS policy protocol COPS routing protocol supports static routing, while routing protocols VPN such as RIP 1/2, OSPF, BGP, IS-IS, MPLS LDP supports MPLS L3 VPN(RFC4364), MPLS L2 VPN and VPLS services, and also supports PWE3. Support L2TP access VPN, which can be used as LAC and LNS. Strictly follow relevant standards and fully communicate with other mainstream manufacturers; Support GRE tunnel protocol. Provide multi-ISP service wholesale function through L2TP, GRE and LSP tunnels; QoS provides DiffServ QoS guarantee based on user priority and complex flow classification rules to distinguish users from services. Follow the QoS service model of DSL forum TR059, provide users with dynamic service and QoS selection, and provide service QoS control strategy based on CAC for call session service, and control all kinds of services carried by various terminals, including bandwidth restriction, access control, access control between different terminals, etc. Perceive and classify the accessed services, and provide differentiated services for the classified services, including limiting the maximum bandwidth CAR and ensuring the minimum bandwidth for each type of service flow, controlling different priorities for various services, and supporting traffic supervision and traffic shaping for 5 12K flows. According to the QoS identification of traffic flow marks/remarks, different services are diverted to different service networks or different MPLS VPN service planes through policy routing to ensure the QoS of carrier-level services in the whole bearer network. Each interface board can support 64K traffic classification rules. Support 802.3x flow control protocol and use WRED to avoid congestion. Multicast supports IGMP protocol, static multicast configuration, PIM-DM/SM, MBGP multicast routing protocol; Support interoperability among multiple multicast protocols; Support multicast policy processing, including multicast routing protocol and multicast forwarding policy processing, and support multicast QoS. The important components supporting the reliability of IPTV service based on controllable multicast are redundant backup (including system control management, routing processing module, switching network, power supply, clock, internal system management bus, fan, etc.). ), and all components are hot-swappable, which supports state-based hot backup switching, and ensures that the business is not interrupted during the active/standby switching. Provide comprehensive and reliable protection protocols, such as port binding, ASSP protocol, VRRP protocol, RPR, RRPP, BFD, GR, FRR and so on. So as to ensure the reliability of services during networking. Firewall supports stateful firewall and provides state tracking and processing of various protocols. DPI supports message depth detection and provides content-based service monitoring and management. The number of concurrent users is 64K 64K 32K, and the maximum number of configured users is 5 12K 256K 128K. Support access protocols PPPoX(PPPoE, PPPoA, PPPoEoA), DHCP, L2TP, ARP, 802. 1x and other charging radius protocols. TACACS+ protocol security has the functions of identity authentication, resource protection, attack prevention and address forgery prevention. IP+MAC+PVC/VLAN ID bundle, each PVC/VLAN ID can limit the number of users accessing. CAR limits the available bandwidth of users, ranging from 64 kbps to 1 Gbps, with steps of 8Kbps. Network management adopts modular Huawei network management platform iManager, which supports SNMP protocol and client/server architecture and can run in UNIX/WINDOWS and SYBASE/SQL SERVER environments. Provide dynamic topology management, fault management, performance management, configuration tools, equipment log management, network management system itself operation monitoring, security and user management and other functions; Provide VPN management, QOS policy management and other business management functions; Provide multilingual support; Input power DC:-36V ~-75V/AC (110v/220v): 90V ~ 264V Full-load power consumption less than 1000W less than 600W less than 350W Full-load maximum weight less than 85kg less than 50kg less than 35kg Mean Time Between Failures (MTBF) ≥ 45 kg.
