• Step 2: planning network design
• Step 3: select hardware, software,
• Step 4: deploy configuration system network

Bước 1: Phân tích nhu cầu hệ thống mạng của doanh nghiệp

This is the first step the most important in the process system design, network for businessdefine clearly the specific requirements of performance, security, scale, objectives of the network. The factors that should be considered include:

• Scale business type: Big business or small business type manufacturer or service all affect the choice of network architecture. Small businesses often require the system simple, less equipment, structures, management is not complicated. Meanwhile, large enterprises or multinational need a network system capable of connecting multiple offices, branches, support thousands of users.
• Number of users connected devices: The number of users along with the device (computer, server, smart phone, printer etc.) directly affect the load of the network. - Defined number of users to help predict the flow of data, the demand for bandwidth. 
• Application use: Apps such as email, cloud storage, software, financial management, ERP, CRM, or applications related to multimedia (video conference, live streaming) requires a bandwidth different. This will help network design to meet the needs of each type of application.

Step 2: planning the system design, network for business

After you have clearly identified needs, need plan design the system network details, including steps such as:

• Split-system network into different segments such as LAN (Local Area Network), WAN (Wide Area Network), wireless network (Wi-Fi, internal network). Each segment has a private function, help optimize performance and security capabilities. For example, business construction system LAN to connect the equipment in the office, while the WAN connection more branches in the geographical area different.
• Mapping network architecture: This diagram describes the connection between the network device (router, switch, access point), the data transmission lines (cables, wireless), by the network, LAN, WAN, Wi-Fi link with each other. This diagram helps to easily visualize the overall network architecture and is the basis to perform the implementation steps after this.

Step 3: choose the hardware, the software for network system

A network system efficiency need to have the optimal combination between hardware and software. Correct selection of equipment, tools will ensure network operation stability, safety, high performance.

The necessary equipment: The basic equipment includes Router, Switch, Firewall, Server.

• Router help manage and navigate traffic between the LAN and WAN network.
• Switch be used to connect devices in the internal network, split flow in an efficient way.
• Firewall to ensure security, prevent the attack from outside, traffic management, in/out.
• Business casual buy Server to store data and application support to operate the business.

Choose the operating system and network management software

Businesses also need to select the operating system for the server (such as Windows Server, Linux), the network management software. This software helps to monitor network traffic, detect, troubleshoot, and optimize the distribution of network resources. In addition, the network management software can help your business automate the process of maintenance upgrades.

Step 4: deploy configuration system network business

The last step is deploy network systems for the actual business, make configuration to ensure the system works efficiently.

• Device settings – software

The installation includes setting up the router, switch, firewall, access points, wireless. These devices should be placed at strategic locations to ensure coverage ability well optimized traffic. At the same time, network management software is also installed on the server to start monitoring network controller.

• Configure IP security configuration and test the connection:
  

After hardware installation, should proceed to configure the IP addresses for the devices and users in the network. Security configuration needs to be set, including measures such as data encryption, access control, firewall settings (firewall). Upon completion, technicians, Lac Viet test the connection to ensure that all the equipment works well, stable network connection, network speed, satisfactory. This helps to quickly detect fix the problem before the system network officially went into operation.

5. Các yếu tố quan trọng trong thiết kế mạng cho doanh nghiệp

When unit selection system design, network for business, ensuring performance, security and scalability is extremely important. Here are the important criteria when choosing a service network design for business:

5.1 performance and bandwidth

The performance of the network depends on the ability to transmit processed data between the device, including computer, servers, mobile devices. A network system has a large bandwidth to help businesses avoid the congestion status data to ensure information flow circulation stability.

• Bandwidth is the ability to transmit data through the network in a certain period of time, usually measured in Mbps or Gbps. Businesses need to calculate the bandwidth required based on the number of users, the app uses a lot of resources (such as video conferencing, data transmission), the development trend in the future.
• Latency is the period of time required for a data packet moves from the sending device to the receiving device. Network system has low latency will ensure quick feedback to improve the user experience, especially in the real-time application such as video call or online conference.
• Quality of service là mechanisms help prioritize the types of data more important (like VoIP calls, streaming video) in comparison with the data packet typically other. 

5.2 Ability to network security

Network security is one of the factors of survival for any business, especially in the context of network attacks, data breaches, increasingly sophisticated.

• Firewall (Firewall): A firewall is a shield first help prevent attacks from the outside. When designing the network, selecting among firewall hardware and software or a combination of both will depend on the scale and nature of the business. A system, a good firewall will monitor network traffic, detect blocked the suspicious behavior.
• Encryption (Encryption): The encrypted data even if storage and transmission, helps protect sensitive information such as financial data, customer information or business plan. The encryption technology common include SSL/TLS for web VPN for remote connection.
• Detection system intrusion prevention (IDS/IPS): IDS detection of unusual activity, help in early detection of threat. IPS have the ability to prevent attacks as they happen. Business should implement both systems to have the multiple layers.
• Access control (Access Control): Decentralized access control is the way to manage who has access to the network resources. 802.1 X, RADIUS or TACACS+ is the solution for access control, common to ensure only the authenticated user is allowed to access the system.

5.3 scalability

When network design for business it should be noted, network systems need the ability to easily expand to support more users, devices and apps without interrupting operation.

• Expand about users: System network must be designed with redundancy to increase the number of users in the future. Including the calculation of the sufficient number of ports on the switch, the ability to dispose of the router, solutions wireless network can meet the needs to use higher.
• Open wide bandwidth: With the demand for data transmission is increasing, the bandwidth should be extended respectively. Switch capable of Gigabit or 10 Gigabit Ethernet,  optical cable is the selected help meet demand growth of bandwidth.
• Cloud and On-premise: System of modern network need to have the ability to integrate well with the solution Cloud for storage, distributed resources, or run the application. At the same time, a number of systems that must continue to use infrastructure on-premise. Therefore, flexibility, extension is very important when businesses need to convert the model to work or resource management.

5.4 redundancy and recovery

Network business need to operate continuously without interruption. Redundancy help the network system to avoid the risk incident to cause interruptions, ensuring high availability.

• Backup device: Enterprises should design the backup system, such as pairs router or switch redundancyto ensure when a device malfunction, other devices can be replaced immediately without interrupting operation.
• Diverse connectivity: For the business depends much on the Internet, having multiple network connections from the various suppliers to help minimize the risks when a connection trouble. Load balancing can be used to distribute the traffic over multiple network connections.
• System backup (Backup System): Backing up data is required to ensure that when an incident occurs, the business can recover quickly. Automatic backup, recurring on cloud or local storage help ensure the continuity of the data.

5.5 Ability to manage monitoring

Software network monitoring help track the status of the devices in the system, traffic monitoring, alerts when there's a problem. Tools such as SolarWinds, Zabbix or Nagios can provide detailed information about the performance of the network and the error report.
With large systems, businesses can use technology automation to manage, configure system network to minimize the error due to human caused, save time in the operating system maintenance.

5.6 optimal cost

Network design for business not only need to meet the technical requirements, but also to balance the cost to suit your budget of the business. Therefore, businesses should consider these factors:

• Deployment costs: The selection of hardware, software, should be based on actual needs. For example, choose between cable and optical cable depends on the bandwidth, long-term cost.
• Operating costs, maintenance: Network systems should be designed for easy management of maintenance help reduce operating costs in the long term. Businesses can weigh in with solutions, virtual network or cloud to optimize the cost of hardware and personnel.

5.7 Support maintenance services

An important factor final is the ability to support system maintenance. When designing a system, network, enterprises need to:

• Technical support: Choosing equipment suppliers, software reputation service, 24/7 technical support are factors that help businesses maintain operations network stable, quickly troubleshoot issues when needed.
• Periodic maintenance: Businesses need to plan for periodic maintenance to check, upgrade systems, including the updated security software, check the device hardware, adjust the system configuration.
