How MPLS route switches optimize man

MPLS route switches in China are still widely used. So I studied how MPLS route switches optimize the telecom man. I would like to share with you here, hoping they will be useful to you. The MPLS route switch is widely recognized by the industry with its unique technical advantages. The MPLS-based VPN technology is currently the only technology that can provide fully-interconnected high-speed communication services on a large scale, telecom operators are paying close attention to the development of MPLS and related technologies, and are constantly seeking for New Application Models and occasions.

In its guidance on the development of communication networks in the next few years, the Ministry of Information Industry has made it clear that MPLS route switches are essential technologies for modern Telecom IP networks. However, based on the data networks of China Telecom Operators, how to Make MPLS practical and effectively extend to quickly access users, and how to deploy MPLS for the whole network is a hot topic discussed in the Chinese industry. For the current IP Man, there are two typical MPLS models for deploying the entire network.

Build full-network MPLS with vro

Currently, medium and high-end router products in the industry support MPLS. Therefore, it is no longer difficult to build a network-wide MPLS with routers. At present, the operator's man structure is generally set up in the router + layer-3 switch mode. The whole network MPLS network needs to be built using a router, and the current network needs to be completely built, this is equivalent to rebuilding an ip man created by a pure router. It is relatively expensive in terms of network construction costs, and the network structure and application mode are inconsistent with the existing network structure and customer group objectives, therefore, it is difficult to achieve this in the current IP Man.

Build full-network MPLS with "router + layer-3 Switch"

Creating an ip man using a "router + layer-3 Switch" is a typical network construction mode in the industry, therefore, in this network architecture mode, the MPLS route switch service for the entire network will bring many benefits to the operation of the current network: 1. in line with the current network structure, the MPLS route switch is an essential technology for the IP network. Implementation must be considered in advance to solve the problem of the existing IP network; 2. for MPLS networks, PE is placed close to the user for network management, which is easy for major VPN customers. Other technologies, such as transmitting packets to the convergence layer PE through VLAN on the user side or using L2 tunneling, network management is relatively complex, and the customer's acceptance is low; 3. PE uses a layer-3 switch that can take into account the access of a large number of existing DSL and LAN broadband service subjects, and can access major VPN customers nearby, in line with the operating interests of the current network, the cost effectiveness is much higher than that of creating a router-only VPN network.

In order to promote the network-wide and practical process of IP Man MPLS route switch services, ZTE focuses on ZXR10MPLS route switch series T160, T64C, T32C, and T16C (T16C is currently the only low-end three-tier switch in the industry that supports MPLS functions) for man optimization, the ZXR10MPLS route switch provides completely hardware-based L2/L3/L4 route exchange capabilities. It supports full-network MPLSVPN and full-network QoS, the full range of products support high-performance NAT and refined bandwidth control. Specifically, ZTE's MPLS route switch series have distinctive technical characteristics in the following aspects: supports full-network MPLSVPN, hardware NAT, powerful anti-virus capabilities, comprehensive bandwidth control capabilities, a wide range of interface types, and layer-2 passthrough Based on POS ports.
