Technology intelligent fault-tolerant architecture H3C IRF2

The S9850 series switches from H3C implement Intelligent Resilient Framework 2 (IRF2) technology. IRF2 provides the following benefits:

Excellent scalability: With IRF2, device aggregation can be plug-and-play by simply adding one or more switches to the stack IRF2 and enabling IRF2 stacking mode on the new device. New devices can be managed through a single shared IP address, allowing software updates to be carried out simultaneously on all devices to reduce network expansion costs.

High reliability: patented IRF2’s 1:N redundancy technology allows each of the slaves in the IRF2 stack to serve as a backup to the master, providing control plane redundancy, data link redundancy, and uninterrupted Layer 3 forwarding. This improves reliability and helps avoid interruptions at work and generally improve productivity. If the primary device fails, traffic does not stop.

Load balancing: IRF2 supports link aggregation across devices, allowing connections to higher and higher-level devices low level using multiple physical channels. This creates another layer of redundancy in the network and promotes fuller utilization of network resources.

Availability: IRF2 technology is implemented by H3C over standard 100 Gigabit Ethernet (100GE) ports or 40 Gigabit Ethernet (40GE). It allows you to allocate bandwidth for both service and application traffic, providing the necessary separation between local traffic and traffic to upstream systems. IRF2 rules can be applied not only at the scale of one rack or adjacent racks, but also at the scale of the entire local network.

Various means increasing reliability

< p style="font-weight: 400;">The S9850 series switches implement various protection schemes to improve reliability at both the switch and link levels. All models, Equipped with overcurrent, overvoltage and overheating protection, they support redundant, removable power supplies, allowing you to flexibly select AC or DC power supplies depending on your actual needs. All switches in the line support fault detection and alarm transmission for power supplies and fan modules, as well as adjusting fan speed based on ambient temperature.

The switches support a variety of channel reservation technologies, such as proprietary H3C developments – RRPP, VRRPE and Smart Link. These technologies ensure rapid network convergence even when the network carries large volumes of traffic from many different services.

Wide < b>selection functions controls quality service (QoS)

H3C S9850 Series switches support Layer 2 to Layer 4 packet filtering, which allows traffic classification based on source MAC address, destination MAC address, source IP address, IP address destination, TCP/UDP port number, protocol type and VLAN.

Each of the 100G ports provides flexible queue scheduling algorithms that can be used simultaneously on both port level and at the queue level.

S9850 series switches support five queuing methods, including Strict Priority (SP), Weighted Round Robin service (Weighted Round Robin, WRR), SP+WRR, weighted fair queuing (WFQ) and SP+WFQ.

Series switches The S9850 supports Committed Access Rate (CAR) functionality with a minimum tuning step of 8 kbps, as well as port mirroring in both directions, which is used to monitor traffic on a specific port and forward packets of the duplicated port to the monitoring port for detection and troubleshooting network problems.

Comprehensive policies < strong>ensuring security

H3C S9850 Series switches support authentication, authorization and accounting (AAA), RADIUS authentication, user account authentication, IP address, MAC address, VLAN and port user authentication, and dynamic and static binding; when paired with the H3C IMC network management platform, they provide real-time management, instant diagnostics, and suppression of unacceptable network behavior.

H3C’s S9850 Series switches support advanced ACL-based management capabilities, allowing multiple ACLs to be defined for each ingress and egress port, as well as VLAN-based ACLs to simplify user registration and enable Avoid wasting ACL resources Additionally, the S9850 series switches take full advantage of Unicast Reverse Path Forwarding (uRPF) technology. When a device receives a packet, it checks the return route to confirm the source address where the packet supposedly came from, and discards the packet if there is no such path.
