Background

After years of operation, the business and scale of a group are constantly developing. The management and it Department of the company also realize that through information means, the business operation of the company can be better supported and the production and management efficiency of the enterprise can be improved. At the same time, with the completion of new office buildings, R & D buildings and plants, it departments also need to plan and build the informatization and enterprise IT infrastructure of the whole group. At present, it is mainly divided into the following two parts:

Intelligent building planning and construction scheme: mainly including video monitoring, access control system, voice and data node planning and wiring, CATV, large screen electronic display, computer room construction, etc.

Enterprise IT infrastructure planning and solutions: mainly including enterprise LAN basic network topology planning and network equipment selection, Internet access and VPN access, it hardware deployment and selection, enterprise it informatization basic software system planning and selection, etc.

This plan is mainly aimed at the IT infrastructure planning of a group enterprise, and puts forward solutions and investment budgets. For the plan of intelligent building planning and construction, please refer to other relevant plans.

Enterprise IT architecture

For the general it architecture of enterprises, this scheme mainly plans for the IT infrastructure, and provides reference for selection and deployment. For the planning and construction of enterprise IT business application system, please refer to other schemes.

Network system planning

At present, enterprises generally have limited investment in informatization. In addition to the limited manpower, there is also a lack of professionals, and the application ability, maintenance ability, development ability, implementation ability, etc. are generally weak, which requires the network architecture to be mature, stable, safe, highly reliable, highly available, and to invest as little manpower and money as possible in maintenance. Secondly, as the primary solution of the enterprise is the survival problem, there is no way to achieve "informatization before business", so the implementation requirements of network construction must be easy and the implementation time must be very short.

The main elements of the enterprise's Networking Scheme include: LAN, WAN connection, network management and security. Specifically, enterprise networking requirements:

Ø establish a safe network structure and network connection between headquarters and branches;

Ø secure network deployment to ensure the normal operation of the enterprise;

Ø provide IPSec or SSL VPN mode for personnel on business trips;

Ø provide intelligent management features to support browser graphics management;

Ø the network design is easy to upgrade and is conducive to investment protection.

The general networking structure of enterprises is shown in the figure below. The core layer of large enterprise network generally adopts the topology of redundant nodes and redundant lines, while small enterprises adopt the connection mode of single line.

By analyzing the informatization situation and network planning elements of general enterprises, on the whole, the planning scheme must have the following characteristics:

Ø the network management is simple. It adopts an easy-to-use browser based method to manage the network with an intuitive graphical interface.

Users can adopt a variety of WAN connection methods, so as to reduce the cost of WAN link.

Ø wireless access points have wide coverage, flexible configuration and convenient mobile office.

The convenient and simple unified communication system can easily realize the interactive working environment.

Bandwidth compression technology and the application of advanced QoS can effectively reduce the link traffic of Wan.

With the development of the company's business, all network equipment can continue to be used after upgrading the original network, effectively realizing investment protection.

Ø the system is safe and confidential, and a low-cost network security solution suitable for enterprises is applied.
