Analysis and Design of Local Area Networks in Residential Quarters 20

Look at your fixed IP is 192, maybe you still have a router on it, your router should never set a fixed, static IP address, if your router changes the address that slides back to the same as the default gateway of the cell, you should change the address of your nuclear starvation router to a different address.

Hello classmates, I am Zhu Qian, please answer by yourself and refuse to plagiarize.

LAN security: 1. Physical security: refers to the security of the network environment of the computer room, the standardized deployment of the computer room, the maintenance of temperature and humidity, the prevention of dust, anti-electromagnetic interference, etc., which can prevent fires and other situations.

2. Network structure System security: consider redundant links in the network topology, set up firewalls, set up intrusion detection, and set up real-time monitoring systems. Set up strict internal and external network isolation Different areas of the intranet are physically isolated, and multiple different broadcast domains are divided.

Network security detection, network monitoring and control (online behavior management software).

The above is a simple list of some precautions for LAN security, and there are many things that need to be paid attention to. Personally, I feel that this part is a little simpler, one is installed in the firewall, and one is installed in the Internet behavior management software.

Firewall Huawei or Cisco firewall is recommended, and Internet behavior management software is recommended lanecat.

This is more intuitive to look at the computer manager security report, and you will find that the current network environment is not good, so we need to pay more attention to protecting the security of the computer.

The virus that is specifically harmful to the LAN is the ARP virus, which can be strengthened by the ARP firewall in the PC Manager Toolbox.

1. Do it yourself. Pull the network cable into the home, arrange the cabinet in the unit, connect to the mains, and place the switch. Optical fiber (network cable) into the control center.

2. Outsourced network companies.

Background of the project environment.

The needs of the customer.

Analysis is required. Schematic design.

Engineering construction. Project acceptance.

The purpose is the design and planning of the LAN of the intelligent community.

This you understand the analysis. Target.

Okay, there is. n The content is given in its entirety.

Solve the problem that the public network address is insufficient. Internet addresses are seriously insufficient in today's society, so the public network address can be shared through the LAN assumption to save public IP address resources.

Block security issues from the public network. The establishment of the LAN makes it possible to have a gateway, server or router with the Internet, and a security audit mechanism can be established to effectively block the access and attack of Internet devices to the equipment on the network.

LAN design can improve the efficiency of intra-network transmission.

It's a very simple thing, involving a layer 2 protocol and a simple layer 3 protocol. To tell you a simple way, go to H3C** to find a LAN solution, and you're good to go.

Your requirements are not clear, so you naturally don't know what strategies are needed, whether you can assume a network environment and simulate it to achieve the desired effect...

I'm going to choose the same as you. , so that people can quote you.
