Comprehensive reliability mechanism
• Besides STP, RSTP, and MSTP, the S5320-EI like S5320-50X-EI-46S-AC supports enhanced Ethernet reliability technologies such as Smart Link and RRPP (Rapid Ring Protection Protocol), which implement millisecond-level protection switchover and ensure network reliability. It also provides Smart Link multi-instance and RRPP multiinstance to implement load balancing among links, optimizing bandwidth usage.
• The S5320-EI supports enhanced trunk (E-Trunk) that enables a CE to be dual-homed to two PEs (S5320s).
E-Trunk greatly enhances link reliability between devices and implements link aggregation between
devices. This improves reliability of access devices.
• The S5320-EI supports the Smart Ethernet Protection (SEP) protocol, a ring network protocol applied to the link layer on an Ethernet network. SEP can be used on open ring networks and can be deployed on upper-layer aggregation devices to provide fast switchover (within 50 ms), ensuring non-stop transmission of services. SEP features simplicity, high reliability, fast switchover, easy maintenance, and flexible topology, facilitating network planning and management.
• The S5320-EI supports Ethernet Ring Protection Switching (ERPS), also referred to as G.8032. As the latest ring network protocol, ERPS was developed based on traditional Ethernet MAC and bridging functions and uses mature Ethernet OAM function and a Ring Automatic Protection Switching(R-APS) mechanism to implement millisecond-level protection switching. ERPS supports various services and allows flexible networking, helping customers build a network with lower OPEX and CAPEX.
• The S5320-EI supports redundant power supplies, and can use an AC power supply and a DC power simultaneously. Users can choose a single power supply or use two power supplies to ensure device reliability.
• The S5320-EI supports VRRP, and can set up VRRP groups with other Layer 3 switches. VRRP provides redundant routes to ensure stable and reliable communication. Multiple equal-cost routes to an uplink device can be configured on the S5320-EI to provide route redundancy. When an active route is unreachable, traffic is switched to a backup route.
• The S5320-EI supports Bidirectional Forwarding Detection (BFD) and provides millisecond-level detection for protocols such as OSPF, IS-IS, VRRP, and PIM to improve network reliability. The S5320-EI complies with IEEE 802.3ah and 802.1ag. IEEE 802.3ah defines the mechanism for detecting faults on direct links over the Ethernet in the first mile, and 802.1ag defines the mechanism for end-to-end service fault detection. The S5320-EI supports Y.1731. Besides fast end-to-end service fault detection, the S5320-EI can use the performance measurement tools defined in Y.1731 to monitor network performance, providing accurate data about network quality.
