LAN system solution for small and medium enterprises

The system includes Wi-Fi, Camera, Voice IP, PC services attached from the branch switch to transmit data to the center through the central switch. At the center, there will be a central switch that coordinates traffic to branch switches through the corresponding VLANs and is managed by the Main Router. At the central switch, there will be switchboard equipment, camera recorders, servers, etc., which is a centralized place to store all important data, images, and voice for the company.

1. Master plan

2. Overview

– The system includes services including Wi-Fi, Camera, Voice IP, PC attached from the branch switch to transmit data to the center through the central switch – At the center, there will be 1 central switch that coordinates traffic to the branch switches through the corresponding VLANs and is managed by the Main Router
– At the central
switch, there will be switchboard devices, camera recorder, server,.. is a centralized place to store all important data, images, voices for the company
– In order to distribute traffic accurately and reasonably, the main router must configure VLANs corresponding to the services, the central switches and branch switches must comply with the VLAN Main Router V3900.
– Main router:
o Divide VLANs corresponding to each service
o Ensure internet
stability o Distribute data areas from the inside out and vice versa

3. Connect Main Router device and VLAN transmission of access devices such as camera, Wi-Fi, PC, Voice IP …

4. Connect Main Router equipment and VLAN transmission of central devices such as switchboards, recorders, servers …

5. Data transmission mechanism of VLANs

From the camera device, it will transmit data to the recorder via VLAN 10
– Phone voice Ip transmits voice images to the switchboard through VLAN 20
– Internal computer shares, stores data about the Server via VLAN 30
– Wi-Fi for guests to the Internet via VLAN 40

6. Advantages of using VLANs

– VLAN-based traffic division system helps the system not to conflict with services, avoid broadcasts from other devices, easily manage services and troubleshoot problems easily when problems occur, minimize attacks from the outside in and vice versa.
– High security, strict decentralization, user
management – The system develops sustainably and upgrades the system in the future without affecting the current device.
– Branch switch and data center switch combine 1 Gb ~ 6 Gb bandwidth to make internal data transmission faster.
