Powerful support for services
The S5700 supports IGMP v1/v2/v3 snooping, IGMP filter, IGMP fast leave, and IGMP proxy. The S5700 supports wire-speed replication of multicast packets between VLANs, multicast load balancing among member interfaces of a trunk, and controllable multicast, meeting requirements for IPTV and other multicast services.
The S5700 provides the Multi-VPN-Instance CE (MCE) function to isolate users in different VLANs, ensuring data security and reducing costs.
S5700HI switches are cost-effective case-shaped MPLS switches. They support MPLS, VPLS and VLL functions and can be used as high-quality access devices to provide leased line services for enterprises.
Comprehensive reliability mechanisms
Besides STP, RSTP, and MSTP, the S5700 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. The S5700 also provides Smart Link multi-instance and RRPP multi-instance to implement load balancing among links, optimizing bandwidth usage.
The S5700 supports enhanced trunk (E-Trunk), which enables a CE to be dual-homed to two PEs (S5700s). E-Trunk greatly enhances link reliability and implements link aggregation between devices, which improves reliability of access devices.
The S5700 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 continuous transmission of services. SEP features simplicity, high reliability, fast switchover, easy maintenance, and flexible topology, facilitating network planning and management.
The S5700 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 S5700 supports redundant power supplies, and can use an AC and DC power supply simultaneously. Users can choose a single power supply or two power supplies to ensure device reliability.
The S5700EI 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 S5700 to provide route redundancy. When an active route is unreachable, traffic is switched to a backup route.
The S5700 supports BFD, which improves network reliability by providing millisecond-level fault detection for protocols such as OSPF, IS-IS, VRRP, and PIM. Complying with IEEE 802.3ah and 802.1ag, the S5700 supports point-to-point Ethernet fault management and can detect faults within the last mile of an Ethernet link to users.
The S5700HI provides 3.3 millisecond hardware-based Ethernet OAM function and Y.1731, which can quickly detect and locate faults. Using the Ethernet OAM and switchover technologies, the S5700 can provide millisecond-level protective switchovers for networks.
