Maipu MyPower S3900 Series Switch
MyPower S3900 is the carrier-class Ethernet aggregation switch. It supports next generation L2 and L3 features and meets the requirements of customers for QoS, OAM, VPN, Multi-service and Protection. Its hardware adopts the fifth generation distributed structure to support the IPv6/MPLS/OAM technologies.
S3900 can help customers develop IPTV, VoIP, VPN, wireless access and TDMoIP services. The high integrated platform design meets the requirement of the customer that a box provides rich physical interface and software features to reduce the total cost (TCO) and operating expenses (OpEx).
MyPower S3900 adopts the dual power supply redundancy, high-integrated E1/T1 interface, and optical-electric Ethernet access. It is suitable for carriers to deploy the medium and small aggregation nodes with service access nodes, develop multi-service access (wireless, VPN, and mobile), and complete the reconstruction from TDM to IP.
MyPower S3900 series includes one model with multiple modules and can meet the requirements of carriers’ district access, base station access and business building access. It provides various VPN services.
A single S3900 supports the 64 E1/T1 interfaces (TDMoIP) to meet the requirement of carriers to transmit 2G and 3G base station services to the aggregation node via IP network and then recover to E1/T1 connected to BSC/RNC, and access the traditional TDM devices such as PBX, realizing unified IP bearing; supports Ethernet fiber access and twisted-pair electric access for carriers to access services and remote commercial customers in the machine room.
Currently, S3900 is one of Ethernet access devices that support perfect OAM. It can help carriers to manage the network more efficiently. In this way, the operation cost of customers is reduced. The supported OAM standards include 802.1ag, 802.3ah and E-LMI.
S3900 passes MEF9 and MEF14 authentications of MEF, and supports the three VPN services including EPL, EVPL and E-LAN defined by MEF to help carriers open various VPN services for customers.
Considering carriers, S3900 defines all downstream interfaces as UNI interfaces. By default, UNI interfaces are disabled and have no local switching function. And the data on UNI interface is not sent to CPU, which ensures the device security. By default, NNI interfaces are enabled, which is convenient for carriers to manage remotely.
50ms service protection
S3900 adopts Ethernet ring protection technology of Maipu, which can realize 50ms network protection in single-ring, dual-ring/multi-ring, tangent-ring and crossover-ring networking environments. In this way, the service continuity of carriers is ensured and customer satisfaction is improved.
New generation switching structure to realize distributed wire-speed processing IPv6/MPLS function
S3900 supports rich IPv6/MPLS features and distributed full wire-speed hardware IPv6/MPLS forwarding mode to realize the intra-board and inter-board wire-speed processing of IPv6/MPLS packets, avoid the bottleneck and delay problems of the centralized forwarding, and provide the strong guarantee for the large-scale commercial applications of IPv6/MPLS.
S3900 adopts dual-power redundancy design. Each power can access different power supply networks. In this way, the hot backup for power modules (to prevent power supply fault) and the backup for power supply network (to prevent the power-off of power company) are realized.
Each port of S3900 supports eight queues and the queue scheduling policies such as SP, RR, WRR, and WDRR; rich priority mappings including 802.1p 802.1p, 802.1p COS, DSCP 802.1p, and DSCP DSCP; 64Kbps-based port traffic rate restriction and carriers can limit the rate according to the time period; Tail Drop and sRED packet loss algorithm.
S3900 supports single-rate three-color mode (srTCM) and dual-rate three-color mode (trTCM) to meet the SLA requirements of operators, including CIR, CBS and PIR.
S3900 supports 1024 concurrent multicast data flow; IGMP snooping and IGMP fast-adding/leaving protocol; L3 PIM and PIM-DM/SM protocol to meet the requirement of customers for multicast protocol.
Powerful anti-attack checking capability
S3900 supports LAND, SYN Flood, Smurf, Ping Flood, Teardrop and Ping of Death and defines the processing policies for attack packets to ensure the device and network security.
S3900 supports 802.1x access authentication modes, and Radius and TACAS+ protocols to meet the requirements of operators’ access authentication, authorization and accounting for customers.
