It can flexibly carry video services, such as Internet Protocol Television (IPTV), and satisfy multicast service requirements on networks of various scales.
SRv6-powered intelligent connections
SRv6 is a future-oriented, next-generation simplified protocol that inherently supports IPv6, allowing access of numerous terminals. SRv6 and Huawei's Network Cloud Engine (NCE) enable cloud-based network resource adjustment, one-hop access to the cloud, and service provisioning within minutes. SRv6 can identify applications and tenants to implement intelligent traffic steering based on indicators such as latency and bandwidth, ensuring SLAs. In addition, SRv6 simplifies protocols and configurations.
Comprehensive network slicing functions
The device provides a comprehensive range of network slicing functions to meet diversified SLA requirements as well as high-quality QoS capabilities and advanced queue scheduling and congestion control algorithms. On the user side, the device supports a 5-level hierarchical QoS (HQoS) scheduling mechanism, meeting the diversified service requirements of different users. On the network side, the device supports MPLS HQoS, and QoS can be deployed to provide QoS capabilities for MPLS VPN, virtual leased line (VLL), and pseudo-wire emulation edge to edge (PWE3) services. In addition, the device implements precise multi-level scheduling of data flows, meeting SLA quality requirements of different users and services of different classes.
The device excels at allocating network resources and can provide a network-wide QoS solution to meet SLA requirements of services with different priorities.
Full-lifecycle automation
NCE enables full-lifecycle automation and real-time visualization across the entire network. Precise in-band flow detection based on NCE and iFIT enables real-time visualization of service quality and fault locating within minutes.
High-precision 1588v2 clock solution
- IEEE 1588v2, a standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems, defines a Precision Time Protocol (PTP), which can achieve time and frequency synchronization with an accuracy of sub-microseconds.
- The 1588v2 standard enables time and frequency synchronization to meet the requirements of the G8273.2 standard. The high-precision time meet the requirements of wireless and Long Term Evolution (LTE) networks. The time jitter among multiple nodes (less than 30 nodes) is less than 1 µs, allowing for large-scale networking. The device automatically selects an external clock source, which can be assigned different priorities, as its reference clock source based on parameters such as these priorities and the number of hops between itself and external clock sources. If the best external clock source fails, the device automatically selects the next-best external clock source as its reference clock source. An NE switchover can be completed within 200 ns, ensuring high clock reliability.
- The NMS provides GUI-based clock management.
Future-oriented IPv6-compatible solution
The device supports IPv6 static routes and various IPv6 routing protocols, including OSPFv3, IS-ISv6, and Border Gateway Protocol for IPv6 (BGP4+). In addition, the device provide a large-capacity IPv6 forwarding information base (FIB) and supports IPv6 Access Control Lists (ACLs), and IPv6 policy-based routing. It also supports IPv4/IPv6 dual stacks to enhance network scalability. These features lay the foundation for smooth transition from IPv4 to IPv6.
Multi-level reliability solution
The device provides reliability protection at different levels, including device, network, and service levels. It provides a network-wide reliability solution that fully meets the reliability requirements of different services, and lays the foundation for enterprise service reliability and interconnection with a system availability of 99.999%.
- Network-level reliability: The device uses the following technologies to ensure network-wide reliability and provide end-to-end protection switching within 200 ms for uninterrupted services: IP fast reroute (FRR); Label Distribution Protocol (LDP) FRR; VPN FRR; TE FRR; hot standby; Topology-Independent Loop-free Alternate FRR (TI-LFA); fast convergence of Interior Gateway Protocols (IGP), BGP, and multicast routes; Virtual Router Redundancy Protocol (VRRP); trunk load balancing and backup; Bidirectional Forwarding Detection (BFD); Ethernet OAM; and routing protocol/port/VLAN damping.
- Service-level reliability: The device uses technologies such as VPN FRR, E-VRRP, VLL FRR, Ethernet OAM, multicast dual-root protection, pseudo wire (PW) redundancy, and enhanced trunk (E-Trunk) to provide service-level redundancy backup for L2VPNs and L3VPNs, ensuring stable, reliable, and uninterrupted services.
Energy-efficient design
The device adopts an energy-efficient design to ensure environment-friendly operation.
- An advanced cooling and energy-efficient system, including a ventilation and heat dissipation design and intelligent fans, allows the device to automatically sense and adjust the temperature, greatly improving power utilization.
- The device supports dynamic frequency modulation and intelligent fan speed adjustment, which significantly reduces power consumption and gives the device an advantage in energy efficiency.
