Full-Service Support

Full-Service Support

Powerful Service Support

The NE40E satisfies the service requirements of IP/MPLS bearer networks, MANs, and backbone networks by providing support for a wide range of features and powerful service processing capabilities. The NE40E provides:

  • Powerful routing capabilities

    The NE40E supports super large routing tables and provides Routing Information Protocol (RIP), Open Shortest Path First (OSPF), Intermediate System-to-Intermediate System (IS-IS), Border Gateway Protocol 4 (BGP-4), and multicast routing protocols. The NE40E supports plaintext authentication and ciphertext authentication, as well as fast route convergence. These features ensure network stability and security in complicated routing environments.

  • Strong service bearer capabilities

    The NE40E can have all of L2VPN, L3VPN, and MVPN deployed depending on networking requirements. The NE40E also supports TE, selective 802.1Q-in-802.1Q (QinQ), Dynamic Host Configuration Protocol (DHCP), IP over Ethernet (IPoE), Point-to-Point Protocol over Ethernet (PPPoE), and GRE. The NE40E can provide access for both traditional services and newly emerging services, satisfying the needs of rich multiple service environments.

  • Powerful and expandable multicast capabilities

    The NE40E supports IPv4/IPv6 multicast protocols, such as Protocol Independent Multicast - Sparse Mode (PIM-SM), PIM - Source Specific Multicast (PIM-SSM), Multicast Listener Discovery Version 1 (MLDv1), MLDv2, Internet Group Membership Protocol Version 3 (IGMPv3), MLD Snooping, and IGMP snooping. The NE40E has the flexibility to carry video services, such as Internet Protocol Television (IPTV) services, and satisfy the requirements for multicast services on networks of any scale.

Well-Designed QoS Mechanism

The NE40E provides high-quality QoS. With an advanced queue scheduling algorithm and congestion control algorithm, the NE40E can carry out accurate multi-level scheduling for data flows. This meets the quality requirements of different users and different levels of services.

The well-designed traffic scheduling mechanism of the NE40E provides the following functions to ensure QoS:
  • Five-level HQoS scheduling for the access side to satisfy the service requirements of access users at different levels in a differentiated and diversified manner
  • MPLS HQoS for the network side to provide QoS for MPLS VPN, VLL, and PWE3

The well-designed QoS mechanism enables the NE40E to excel in network resource allocation. The NE40E can provide a network-wide QoS solution to meet the requirements of carrier-class services on enterprise networks.

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 service reliability 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 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 continuous service forwarding.

  • 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, fast convergence of Interior Gateway Protocol (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. The NE40E provides an end-to-end protection switching of 200 ms.

  • 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, PW redundancy, and E-Trunk.

  • 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 G.813 template. 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 us, 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.
