• Dual-device hot backup: IPoE/PPPoE users support 1+1 or 1:1 hot backup for unicast and multicast services. On the L2TP LAC side, IPv4 users support 1:1 hot backup.

High-Accuracy 1588v2 Clock Solution

• IEEE 1588v2 is a standard for the precision clock synchronization protocol for networked measurement and control systems. The 1588v2 standard defines the 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. Accuracy within 100 ns is sufficient to meet the requirements of wireless and LTE networks. The time jitter among multiple nodes (less than 30 nodes) is less than 1 µs, allowing for large-scale networking. External clock sources can be assigned different priorities. A device selects an external clock source as its reference clock source based on factors such as the priorities of external clock sources and the number of hops between itself and external clock sources. After the best external clock source fails, the device automatically selects the second-best external clock source as its reference clock source. An NE switchover can be completed within 200 ns, ensuring the high reliability of clocks.

• The NMS provides GUI-based clock management.

Advanced 2T Platform

The NE40E series, based on a 2T platform, is designed to conserve energy and reduce emissions. 1T and 2T boards are provided. The device can carry large-volume service traffic, satisfying the increasing bandwidth demand of future networks. The VRP-based NE40E-X8AK is compatible with most line cards on live networks, protecting customers' investments to the largest extent. With high port density and compact design, the device effectively reduces the required installation space.

Future-Oriented IPv6-Compatible Solution

The NE40E supports IPv6 static routes and a variety of IPv6 routing protocols, including OSPFv3, IS-ISv6, and BGP4+. In addition, the NE40E provides a large-capacity IPv6 FIB and supports IPv6 terminal access, IPv6 ACLs, and IPv6 policy-based routing. These features lay the foundation for smooth transition to IPv6. The NE40E supports IPv4/IPv6 dual stack and IPv4-to-IPv6 transition technologies and solves problems related to communication between IPv4 and IPv6 networks and between separate IPv6 networks, which enhances network expansibility.

Energy-Conserving Design

The environmentally friendly design of the NE40E conserves energy and reduces emissions.

• The device has an industry-leading cooling and energy-conserving system which includes an advanced ventilation and heat dissipation design, intelligent fans, and a smart power supply distribution design. The device can automatically detect the temperature within the unit and dynamically adjust airflow, which improves power supply utilization.

• The NE40E supports dynamic frequency modulation and intelligent fan speed adjustment. This greatly reduces power consumption and provides more obvious advantages for the NE40E in energy saving.

Flexible VS Functions

As an important feature of the next-generation IP bearer devices, virtual system (VS) plays an active role in centralized operation and reduction of capital expenditure (CAPEX) and operational expenditure (OPEX). Large physical routers (PRs) can be divided into multiple small independent VSs, optimizing physical resource allocation. VSs can:

• Reduce CAPEX and OPEX.

• Flatten networks.

• Support multi-service networks.

  • Different services are deployed on different VSs, forming a logical multi-service network.

  • This isolates different types of services to improve security and reliability.

• Verify new services.

  New services, such as IPv6 and video services, can be verified on VSs. This isolates services and does not affect existing network applications.

Efficient OAM Features

The NE40E provides point-to-point Ethernet fault management in compliance with IEEE 802.3ah and supports CFM OAM for end-to-end fault detection and locating. The device provides Ethernet performance management in compliance with ITU-T Y.1731. By inserting a timestamp into 802.1ag LB messages, the device can measure indicators such as the delay, jitter, and packet loss rate within a specified time period on a specified network segment. Indicator measurement can be configured as a scheduled task and work with the NMS to output network performance statistics reports.

The NE40E uses advanced hierarchical L3 networking and HVPN for mobile bearer networks, especially future-oriented LTE networks, guaranteeing network efficiency, security, and reliability. The Layer 3 to the edge solution improves OAM efficiency, and Huawei innovative IP FPM allows for end-to-end and segment-by-segment fault locating.

The device allows for SDH-network-like OAM, including service monitoring, intelligent alarm reporting, and precise fault locating. ISPs can use performance management tools, such as the NMS, to monitor network operation in real time, determine whether the forwarding capacity of the network complies with the service level agreement (SLA) signed with users, and handle network faults in a timely manner. These functions greatly reduce network maintenance costs.
