Uncover the mystery of Multi-Service Router Performance

At present, the development of multi-service routers is still very rapid, and the demand for users is also very high. Here we will mainly introduce a brief introduction of Multi-Service routers, including introducing high-quality QOS capabilities. The NE20 series multi-service routers can be used as edge devices of the operator's service network, as small POP points, or as high-performance centralized networking devices for the operator's Operation Support Network, it can also serve as the enterprise's central device in the enterprise network or the enterprise's high-performance aggregation of Multi-Service routers. NE20 according to the number of business slot can be divided into NE20E-8, NE20-8, NE20-4, NE20-2 four products.

The fifth generation of Multi-Service Routers:NE20 is different from the same type of Multi-Service Router products that previously used CPU software forwarding. It adopts the industry's high-performance network processor technology to achieve centralized forwarding of High-Speed Interface packets, organically combines software flexibility and hardware performance to provide wire speed forwarding performance, NE20E-8 performance up to 6 Mpps, NE20-8, NE20-4 performance up to 4.5 Mpps. NE20 adopts the High-Speed Interface forwarding and Control Plane Separation Technology. The high-speed interface forwarding engine uses a high-performance network processor, which improves the forwarding performance, control capability, reliability, and security of devices.

High-quality QOS capabilities:The complete QoS mechanism and excellent QOS performance ensure the service quality of different services under heavy load, and provide a complete QoS mechanism based on DiffServ. Supports complex stream classification, precise traffic monitoring, and Traffic Shaping. Provides queue scheduling and congestion avoidance functions, and supports advanced scheduling technologies such as CBWFQ, LLS/NLS, and PBS, using WRED and advanced SA-RED algorithms, RED supports eight levels of discard priority. It precisely guarantees the bandwidth, latency, and jitter indicators of different services, and meets the "differentiated service" requirements of users for multiple service levels.

High reliability:It adopts a highly reliable modular design method. All boards, fans, and power supply modules support hot swapping. It provides dual-power 1 + 1 backup modules with redundant backups and passive backboards; provides software hot Patching Technology to completely smooth upgrade of equipment; supports dynamic routing protocols, MPLS Traffic Engineering, and provides protection mechanisms such as IP/MPLS fast re-routing and vro redundancy protocol VRRP, this effectively ensures high-speed and reliable operation across the network. The entire machine is able to run continuously for 7x24 hours. NE20E-8 is to further enhance the NE20, using multi-service router bus technology, the Board bandwidth can reach 40G at present, has a strong scalability. NE20E-8 route processing board and network processing board provides 1 + 1) redundant Backup, with Fast route Backup FRB: Fast Routing Backup) features, implements hot status-based failover and uninterrupted multi-service router forwarding to provide high-quality service assurance.

Powerful MPLS processing capabilities:Supports mpls vpn and mpls te, and provides high-quality, secure, and multi-layer mpls vpn solutions, which can be used as cost-effective mpls pe devices.

Business capability:The software system is based on a VRP software platform with proprietary intellectual property rights of Huawei. It supports multiple VPNL2TP, GRE, mpls vpn, and so on) and provides a wide range of NAT functions, provides multiple interconnection functions, including Ethernet/VLAN, PPP/MP, PPPoE, Frame Relay, HDLC, ATM, X.25, HDLC, and LAPB.

Multi-Service Router processing capabilities:Supports RIP, OSPF, BGP, IS-IS, IGMP, PIM, MBGP, MSDP, and other multicast routing protocols, and supports routing policies and policy routing.

IPv6 Multi-Service Router capabilities:Fully supports both IPv4 and IPv6 protocols, implements hardware IPv6 forwarding, and provides a wide range of IPV6 protocols. Supports a variety of IPv4 to IPv6 transition technology: Manual Tunnel Configuration, automatic configuration of tunnel, 6to4 tunnel, NAT-PT, etc.; Support IPv6 Static Routing, supports dynamic routing protocols such as BGP4/BGP4 +, RIPng, OSPFv3, and ISISv6. Supports ICMPv6 MIB, UDP6 MIB, TCP6 MIB, and IPv6 MIB.

Maintainability:Supports automatic fault diagnosis. The fault diagnosis software running on a PC can help engineers quickly and accurately locate system faults.
