High Forwarding Performance

As a member of Huawei's 5th generation router family, the NE20E/NE20 adopted Network Processor (NP) technology, taking advantages of both ASIC and CPU. So it features hardware-based high performance (4.5 Mpps) and software-based high flexibility. The NE20E/NE20 router can support fast packet-forwarding on all kinds of interfaces, including the packet with QoS and security information.

Supporting IPv4 and IPv6 Protocol Stacks

The NE20E/NE20 supports IPv4 and IPv6 protocol stacks.

The NE20E/NE20 also supports IPv4-to-IPv6 transition technologies such as manually configured tunnel, automatically configured tunnel, 6to4 tunnel, Network Address Translation-Protocol Translation (NAT-PT), and IPv6 Provider Edge (6PE).

Abundant Services

Supports L2TP-based layer 2 tunnel and GRE-based layer 3 tunnel. Provides a complete suit of network security schemes, such as access control, connectionless integrality and data source authentication, encryption as well as traffic classification, combined with IPSec technologies.

Provides powerful MPLS VPN functions, such as L2/L3 MPLS VPN, traditional L2 VPN, transparently transmitting L2 data of users on MPLS networks, and PE hierarchical architecture (Hierarchy of PE, HoPE).

Supports standard Differentiated Service (Diff-Serv) consisting of complex traffic classification, Traffic Policing (TP), Traffic Shaping (TS), congestion management (PQ/CQ/WFQ/CBQ) and congestion avoidance (WRED), accurately assures the bandwidth and delay for various services. Supports advanced congestion control algorithms such as SARED.

Provides authentication, authorization and accounting (AAA) such as RADIUS and HWTACACS. Supports data transmission using plain-text and Message-Digest Algorithm 5 (MD5) methods. Supports packet filtering (interface-based ACL and ACL based on time range).

Supports NAT.

Carrier-class Reliability

Adopts dual-power redundancy (1+1 backup) module, supports AC-input or DC-input power supplies as well as hot swap. All service interface cards as well as the fan support hot swap. The fan can automatically adjust its speed according to the environment condition.

Provides Backup Center function and Virtual Router Redundancy Protocol (VRRP) technologies to assure unblocked data communication by providing a backup scheme in the event of faults occurring to communication lines or devices, effectively enhancing the network robustness and reliability. The Backup Center supports the backup load balancing function.

Convenient Maintenance Management

Supports local or remote maintenance via Console port, AUX dial-in and Telnet as well as Secure Shell (SSH), preventing attacks such as IP spoofing and plain-text password intercept.

Supports SNMP (V1/V2c/V3) and Client/Server architecture, and can be managed by Network Management System -- iManager N2000.

Supports the automatic fault diagnosis function, which assists the maintenance engineer in locating the system-level fault quickly and accurately via the fault diagnosis software.
