Mpls vpn router and switch purchasing guide (1)

Nowadays, with the popularization and development of the Internet, mpls vpn technology is becoming more and more popular. mpls vpn is a type of MPLS Multiprotocol Label Switching Based Multi-Protocol Label Switching) the technical ip vpn is to use MPLS technology on network routes and exchange devices to simplify the route selection method of the core router, using the IP Virtual Private Network ip vpn implemented by TAG exchange combined with the traditional routing technology), it can be used to construct a broadband Intranet and Extranet, to meet a variety of flexible business needs. It will surely become an important direction for future network security research and Internet applications. Mpls vpn can utilize the extensive and powerful transmission capabilities of Public Backbone Networks to reduce the cost of enterprise internal network construction and greatly improve the flexibility of network operation and management, at the same time, it can meet users' needs for information transmission security, real-time, broadband, and convenience. Therefore, it is mostly used for large-scale network construction.

Huawei and Cisco are the main product manufacturers of mpls vpn technology from the current use of routers and switches in enterprise and e-government networks. From the network products of Huawei manufacturers, the corresponding vrouters and vswitches meet the performance requirements. For example, the Huawei vronene80/40/16/08/05 can be P/PE, and the S8016 layer-3 vswitch can be PE. From the network products of Cisco manufacturers, there are corresponding router products to meet the performance requirements, cisco router GSR 12016/7609/7304/7513/7400/7200 can be used as P/PE, cisco 6509 Layer 3 switch can be used as PE, the application cases of Cisco on the government network mainly include the use of MPLS/VPN on the Heilongjiang Provincial Government network. Huawei's applications on government affairs network mainly include Jiangxi government affairs information network using MPLS/VPN) and Wuhan government affairs information network using MPLS/VPN; the performance of a vro mainly depends on the packet forwarding capacity, the supported port types and density), the routing protocol, NAT, QOS, multicast and mpls vpn. The performance of a vswitch mainly depends on the size of the backplane capacity throughput, supported port types and density), redundant modules, number of VLANs, whether layer-3 switching, multicast, and mpls vpn are supported. Let's take a look at the situation of vro Huawei that meets mpls vpn) and switch products Huawei and Cisco.

Support for mpls vpn Huawei high-end router products take Huawei products as an example)

1. Quidway NetEngine 80 core router　

Quidway NetEngine 80 core router is a high-end network product independently developed by Huawei. It is mainly used in IP backbone networks, IP Man backbone layers, and core locations of various large IP networks. NE80 adopts an Advanced Distributed hardware architecture. It features carrier-level reliability, line rate forwarding performance, a sound QoS mechanism, and rich service processing capabilities, meet the growing data and Internet Business Requirements for backbone network devices.

NE 80

Features:

1) large capacity, high density　

The NE80 core router is a large-capacity Gigabit switching core router with a backplane capacity of 256 Gbps and a system switching capacity of up to 128 Gbps. There are 16 line slots in total, it can provide 16 POS 2.5G/64 POS 622 M/128 POS 155 M/128 ATM 155 M/64 GE/256 FE/16 RPR 2.5G, it has a high density of large capacity and is suitable for the networking and expansion requirements of backbone devices.

2) line rate forwarding performance and powerful routing capabilities　

NE80 adopts the mainstream network processor technology in the industry to achieve IP address, MPLS, and multicast line rate forwarding for all interfaces, including g, with a forwarding performance of 96 Mpps. With powerful routing capabilities, it supports up to 1.7 million large route tables. It supports a wide range of routing protocols, including RIP, OSPF, IS-IS, BGP4, and multicast routing protocols, and IS stable and comfortable in complex routing environments.

3) Telecom-Level Reliability

NE80 adopts distributed hardware forwarding. All key components, including the routing processing system, switching network system, clock system, power supply, and management bus, are redundant hot backups, implements hot switchover based on status and uninterrupted route forwarding. APS technology provides link backup protection, and VRRP achieves load balancing and reliability between devices; dynamic Routing Protocol, MPLS Traffic Engineering, and MPLS re-routing ensure high-speed and reliable network-wide operation.
