It provides uninterrupted forwarding, uninterrupted upgrades, graceful restart, ring network protection, and other high-reliability technologies, improving user productivity while ensuring network uptime, thereby reducing the customer's total cost of ownership (TCO). Furthermore, the H3C S9900E complies with the "Restriction of Hazardous Substances in Electronic Equipment Standard (RoHS)," making it a green and environmentally friendly routing switch.

Features

1AdvancedCLOSMulti-level multi-plane switching architecture

Adopting advancedCLOSA multi-level, multi-plane switching architecture provides continuous bandwidth upgrade capabilities.

Orthogonal mesh design:S9900EThe service boards and switching network boards adopt a fully orthogonal design.(90degree)Cross-line card service traffic is directly connected to the switching network board via orthogonal connectors, reducing backplane cabling to zero (greatly avoiding signal attenuation), significantly improving system bandwidth and evolution capabilities, and allowing the overall capacity to be smoothly expanded to hundreds of thousands.Tbps；

Independent switching network cards, with the control engine and switching network card hardware operating independently, greatly improve equipment reliability and ensure continuous bandwidth upgrades for future products.

2Innovative distributed multi-engine design

It adopts an innovative hardware design, providing the system with powerful control capabilities and millisecond-level high reliability through a fully distributed independent control engine, detection engine, and maintenance engine;

The distributed control engine provides a powerful control processing system for all business boards, easily handling various protocol messages and control messages, and supporting fine-grained control of protocol messages, providing the system with a complete ability to resist protocol message attacks.

A distributed detection engine allows all business boards to operate in a distributed manner.BFD、OAMIt can quickly detect faults and link with the control plane protocol to support fast protection switching and fast convergence. It can achieve millisecond-level fault detection to ensure uninterrupted service.

Distributed maintenance engine, intelligentCPUThe system supports intelligent power management, enabling sequential power-on and power-off of individual boards (reducing power surges caused by simultaneous power-on of individual boards, improving equipment lifespan, reducing electromagnetic radiation, and lowering system power consumption), as well as online device status checks.

3、IRF2(Second-generation intelligent elastic architecture)--Horizontal virtualization

To meet the needs of horizontal business integration within the park network.S9900EsupportIRF2(Second-generation intelligent elastic architecture) technology virtualizes multiple high-end devices into a single logical device, offering significant advantages in reliability, distribution, and manageability, primarily in three aspects:

Reliability: Through hot backup routing technology, redundant backup of all information in the control plane and data plane and uninterrupted three-layer forwarding are achieved throughout the virtual architecture, which greatly enhances the reliability and performance of the virtual architecture, eliminates single points of failure, and avoids business interruption.

Distributed nature: Through distributed cross-device link aggregation technology, load sharing and mutual backup of multiple uplinks are achieved, thereby improving the redundancy of the entire network architecture and the utilization rate of link resources.

Manageability: The entire resilient architecture shares a common...IPManagement simplifies network device management and network topology management, improves operational efficiency, and reduces maintenance costs.

S9900ESupports hardware-level encryption technologyMacsectechnology(802.1aUnlike traditional end-to-end application layer protection software encryption technology,MacsecBy using cryptographic techniques to authenticate data sources, control protocols managing bridged networks and other data are protected, ensuring information integrity and providing re-protection and confidentiality services. Protection is achieved at the source by authenticating frames sent from that station.2Layer protocols are vulnerable to attacks.

Network topology

Network Application 1:IDCSolution

The H3C S9900E series core switches meet the performance requirements of IDC (Internet Data Center) core equipment. They support IRF virtualization technology, enabling large-scale network deployments.

Network Application 2: Multi-service Campus Network

Traditional wireless networking models are inadequate for meeting the demands of services such as IPv6, wireless security, user management, and wireless voice. The H3C S9900E wireless controller + FIT AP control architecture achieves centralized management and configuration of APs, centralized user access control, automatic AP configuration file downloads and software version updates, and also implements functions such as IPv6, wireless security, RF management, and cross-layer 3 roaming, meeting the needs of value-added services such as voice and video. Based on a unified hardware and software platform, the H3C S9900E provides an integrated wired and wireless solution, solving the problems of separating wired and wireless devices, network management, and user management.
