Future-Oriented IPv6-Compatible Solutions

The NE40E supports a variety of IPv6 features including IPv6 leased line, dual stack, tunneling, and translation. The NE40E supports Next Hop Separation to optimize the IPv6 convergence time and , supports larger IPv6 FIB and CGN card of 160G throughput to improve the scalability. All of them help to provide comprehensive solutions based on the high performance for transition from IPv6 to IPv4. And owing to the variety of technologies and different situations of provider networks, each provider will certainly select a conservative, reposeful, or aggressive transition technology that is the most suitable for its own network.

All-Round Reliability Solution

The NE40E provides reliability protection at different levels, including the equipment level, network level, and service level. The NE40E can provide a multi-level reliability solution that completely meets the reliability requirements of different services. The NE40E lays the foundation for enterprise services with a system availability of 99.999%.

The following describes the reliability protection levels that the NE40E provides:

• Equipment-level reliability
  The NE40E provides redundancy backup for key components. These key components support hot swapping and hot backup. The NE40E also uses technologies, such as non-stop routing (NSR), non-stop forwarding (NSF), and in-service software upgrade (ISSU), to ensure uninterrupted service forwarding. The NE40E supports packet buffering of 200 ms, ensuring no packet loss in the case of burst traffic. This guarantees high-quality service experience of users.
• Network-level reliability
  The NE40E uses the following technologies to provide network-level reliability: IP fast reroute (FRR), Label Distribution Protocol (LDP) FRR, VPN FRR, TE FRR, hot standby, Remote LFA, fast convergence of Interior Gateway Protocols (IGP), BGP, and multicast routes, Virtual Router Redundancy Protocol (VRRP), Rapid Ring Protection Protocol (RRPP), trunk load balancing and backup, hardware-based Bidirectional Forwarding Detection (BFD) of 3.3 ms, MPLS OAM, Ethernet OAM, and routing protocol/port/VLAN damping. The NE40E provides an end-to-end protection with no service interruption.
• Service-level reliability
  The NE40E uses the following technologies to provide service-level reliability for L2VPNs and L3VPNs: VPN FRR, E-VRRP, VLL FRR, Ethernet OAM, Y.1731, PW redundancy, E-Trunk, and E-Automatic Protection Switching (APS) These technologies ensure stable and reliable service operation with no service interruption.

Enhanced Metro Ethernet Features
Based on the mature Versatile Routing Platform (VRP), the NE40E excels in reliability, expansibility, and maintainability. It supports various features to satisfied the multi services carried requirement including Hierarchical Virtual Private LAN Service (HVPLS), E-VPN, Virtual Leased Line (VLL), Layer 2 VPN (L2VPN), Layer 3 VPN (L3VPN), multicast VPN, 802.1Q-in-802.1Q (QinQ), Virtual Local Area Network (VLAN) mapping, Dynamic Host Configuration Protocol (DHCP) relay/snooping, IPSec,NAT and GRE.

NE40E supports Protocol Independent Multicast-Source Specific Multicast (PIM-SSM), Internet Group Membership Protocol Version 3 (IGMPv3), and MAC+IP+VLAN user binding. On the high-reliability MANs based on the NE40E, ISP can provide Internet Protocol Television (IPTV) services, family multi-play services, IP leased line services, enterprise interconnection services, and enterprise VPN services.

In addition, the NE40E supports comprehensive Ethernet clock synchronization, which well satisfies the requirements for IP network used in electricity and transportation enterprise.

Enhanced User Management Functions
The NE40E provides Multi Service Edge (MSE) features to manage and control DHCP/IP over Ethernet (IPoE)/leased line access users. The MSE mainly provides dynamic user access, user management, and user-based authentication, accounting, and QoS scheduling. In addition, the MSE implements Bandwidth on Demand (BoD) for different services of enterprise users and for DHCP individual users and changes the unified charging mode to the charging mode based on value-added services, which implements user centered refined service operation.
Efficient OAM features
NE40E support Ethernet OAM fault management including: Ethernet in the First Mile OAM (EFM OAM), conforming to IEEE 802.3ah and Connectivity Fault Management OAM (CFM OAM), conforming to IEEE 802.1ag.
Conforming to ITU-T Y.1731, the NE40E supports performance management to measure the delay, jitter, and packet loss ratio when the messages are transmitted. In this manner, the NE40E can detect the end-to-end performance of traffic in a specified time period and on a specified network segment.
Cooperating with performance management tools such as U2000, NE40E can provide SDH like network OAM, service oriented, intelligent warning, and refined positioning. With supporting efficient and precise performance measurement and test technologies such as IP FPM, TWAMP, RFC2544, G.8032, NE40E can help to simplify the OAM and save the OPEX to a great extend. Besides, the ISP can monitor the network status in real time through the NMS. The ISP then check whether the forwarding capacity of the network complies with the Service Level Agreement (SLA) signed with users and locate faults. The ISP does not need to carry out detection on the user side, which greatly decreases maintenance costs.
