ZXR10 8900 Series Terabit MPLS Routing Switch

ZXR10 8900 series Terabit MPLS routing switches are the latest introduced products by ZTE with high capacity and performance for the core/aggregation layer of the network. This series consist of the following models: ZXR10 8912, 8908, 8905, 8902. ZXR10 8900 family supports L2/L3/L4 wire speed switching capability, mainly positioned at the core/aggregation layer of carrier’s IP MAN, Metro Network and the campus, e-government and corporate network.

Product Positioning

• Carrier-Class Reliability
  Key modules such as system controlling unit and power supply adopt 1:1 mode backup. The high reliability is ensured by Hitless Protection System (HPS). Strict reliability requirements are satisfied when the redundancy control module is properly configured. It supports ZESR intelligent Ethernet technology based on EAPS as well as functions such as VRRP, LACP and STP provide further reliability for users.
• Carrier-Class Ethernet and OAM
  ZXR10 8900 supports PBT based upon MAC IN MAC and PBT-QOS. Besides that it supports as well as TMPLS and EoMPLS, which enables multiple ways for changing traditional Ethernet network to MEN.
  ZXR10 8900 Ethernet OAM bases on IEEE802.1ag, IEEE802.3ah and MPLS OAM which can reduce operators’ OPEX and make the network easier to operate and manage.
• MPLS Features
  ZXR10 8900 features more powerful MPLS capability. Besides MPLS L3 VPN and VPLS/VPWS, it offers more advanced functions such as MPLS TE and MPLS FRR as well.
• DPI Service Module
  DPI service module is designed for checking services via deep packet inspection technology instead of sending packets out directly. Deep Packet Inspection technology identifies traffic accurately, and implements control and statistical analysis. It provides rich control and QOS policies for customers to help them to make the best use of network resource and realize differentiated service based upon user and service, and implement data Stat on the basis of traffic, port and vlan as well.
• FireWall Service Module
  FireWall service module is particularly used for firewall, providing firewall function for the entire system, which offers customers’ networks powerful security; Firewall service module provides many security functions including filtering, anti-attack service, NAT, and security management; it is configured with multiple firewall modules for implementing

Architecture and Key Components

The system uses a large-capacity and high-speed serial bus backplane to connect the main control board to all service line cards. The control and switch matrices supporting 1:1 redundancy are combined in one, A large-capacity switch matrix is used to guarantee the switching capacity that the system may need when it is operating at wire speed. The control board uses a high-performance CPU and large memory to ensure adequate storage space for speedy protocol processing and huge table contents. Each line card provides packet processing capability at wire speed through ASIC and offers 10G, 1Gand 100Minterfaces according to different service.

For software, the operating system ROS is a multi-task, real-time operating system which is the core for software architecture of the routing switch.  It is responsible to manage the hardware architecture of the entire routing switch, providing a uniform operation platform for the applications of the software system. Based on the VxWorks kernel, single-processor based process scheduling, process synchronization, memory management, and timing management shall be implemented. Kernel functions such as communications between processes of the same CPU and between processes of multi-processor shall also be provided for reliable, efficient and stable services for the upper layer. The high reliability, realtimecapability, self-healing, maintainability, simplicity and encapsulating capability have been taken into consider.

ZXR10 8900 series has been deployed in providers’ commercial networks for years.
