NE20ES6E Core Switch Functions

Fiber and communications infrastructure knowledge brief Published 27 Jun 2024

Prepared for preliminary research by the ENSAA knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

The Huawei NE20ES6E serves as a high-performance aggregation and core switch, supporting advanced routing, switching, redundancy, and service-level reliability in enterprise and campus networks.

Deployment Roles

The NE20ES6E, part of the NE20E-S series, can be deployed as: Aggregation node on IP/MPLS networksCore node for small and medium enterprise networksEdge node on campus networksAccess node for small and medium education networks It is designed to work with other NE routers to provide a flexible, scalable network solution for diverse service requirements. Hardware and ArchitectureVRP Operating System: Runs on Huawei's Versatile Routing Platform (VRP) with a Resilient Distributed Framework (RDF), separating management, service, and data planes for high flexibility and reliability.

N

P Chips: Huawei-developed network processors enable hardware-based forwarding and non-blocking switching, supporting high throughput and low latency. Main Processing Unit (MPU) and Network Service Processors (NSP): Support up to 25 million IPv4 BGP routes and 4 million IPv4 FIB entries, ensuring large-scale routing capacity. Hot Swap and Redundancy: Key components support hot swap, hot backup, Non-Stop Routing (NSR), Non-Stop Forwarding (NSF), and In-Service Software Upgrade (ISSU) for uninterrupted service.

Switching and Routing Capabilities

Layer 2 and Layer 3 Switching: Supports VLANs, trunking, and high-speed L2/L3 forwarding. Multicast Support: IPv4/IPv6 multicast protocols including PIM-SM, PIM-SSM, MLDv1/v2, IGMPv3, and IGMP snooping, enabling IPTV and other multicast services.

VPN and Service-

Level Reliability: Provides VPN FRR, E-VRRP, VLL FRR, Ethernet OAM, and PW redundancy, ensuring stable L2VPN and L3VPN operations.

OA

M and Protection Switching: Supports MPLS OAM, Ethernet OAM, and end-to-end protection switching with 200 ms failover without service interruption.

Security and Management

Packet Inspection and ACLs: Ensures packets conform to configured policies for central processing. Flexible Programmable Architecture: Microcode programming allows new service deployment without hardware replacement, reducing operational costs.

Summary

The NE20ES6E is a high-performance, reliable, and scalable core switch suitable for enterprise, campus, and WAN environments. Its combination of advanced routing, multicast, redundancy, and security features, along with hardware-based forwarding and VRP OS, ensures high availability, service continuity, and future-proof network expansion.
