การวางแผนโครงข่ายและการใช้งานจริง

1. Human factors

• Large percent of bandwidth is occupied:

If colleagues in the company use P2P software, such as BT to download or upload files, the bandwidth will be tight, and the network speed will naturally slow down.

• Proper QoS bandwidth management is not set up:

Enterprises fail to assess the importance of each application program in advance and set up appropriate QoS bandwidth management according to the importance level, which causes all programs to compete for bandwidth separately, and the transmission of important information is affected.

2. Hardware factors

• Old and faulty network equipment:

As long as it is an electronic product, there is a possibility of failure and downtime. When the network starts to slow down or disconnect, you should first confirm whether there is a problem with the ATU-R provided by the ISP, and then check each self-owned device to find out the source of disconnection.

• Abnormal line (too long, wrong wiring):

There are too many devices and endpoints, and connection errors may occur more or less during the process of connecting lines. In addition, the network cable connecting devices should not be too long. If it exceeds 100 meters, problems, such as network slowdown and unstable signal will occur.

3. Software factors

• Computer virus:

Some computer viruses will consume the resources of connected devices, while others consume network bandwidth. When a virus infects a computer, it usually spreads itself through emails at a rate of hundreds of emails per minute, occupying most of the computing power and network bandwidth, and the network speed will naturally slow down.

1. Consulting: The service consultant will confirm the customer's problem, assist the customer to clarify the demand at the first time, and set the follow-up planning direction.
2. Environmental assessment: conduct an site survey through a pre-sales consultant to check the enterprise environment and resources.
3. Solution introduction: introduce the solution by an engineering team according to the consensus of both parties, and cooperate with the enterprise to complete the construction of the solution.

• Confirm the number of employees and departments in the enterprise, and whether there is a possibility of expansion in the short term

• Assess the functional requirements of remote connection access, such as: remote office, work from home requirements

• Consider the requirements for connecting related equipment, such as: Internet phone, monitor, access control and attendance system

• Pay attention to the compatibility of the updated equipment with the existing environment

• Assess hardware age and OS version

The network requirements of common commercial small and medium-sized enterprises usually not only include data query and file transmission, but also more business requirements, such as company email system, video conferencing system, cloud collaboration system, monitor, access control and attendance system, VPN (virtual private network), VLAN (Virtual Area Network) services, etc. In addition to network speed and convenience, enterprises must pay attention to network connection security. If there is no careful planning, hackers may obtain users' sensitive information through loopholes. Intrusion and damage may cause serious loss, therefore, in addition to functional applications, for enterprise synchronization, it also needs to plan network security to deal with malicious attacks.
