ONV and Forward-Thinking Protect Heilongjiang Vocational Institute Ecological Engineering

ONV and Forward-Thinking Protect Heilongjiang Vocational Institute Ecological Engineering

Heilongjiang Vocational Institute Ecological Engineering is located in Harbin, China, which covers an area of 237,600 square meters and building area of 79,551 square meters, more than 20 modern multimedia classrooms, the language labs, computer labs, departments, restaurants and library etc., which is demand for a wide scope of HD monitoring coverage over 518 places.

Requirement for Data Transmission System

1. To avoid problems caused by limited switching capacity or poor switch performance of traditional network communication system, such as video and signal packet losses and un smooth video transmission etc.

2. Eliminate the problem of deploying separate power system on each terminal device.

3. A powerful switching function core switch is needed for the solution to provide data transmission for CCTV sever.

4. A managed switch in access layer is required, which supports loop detection, port isolation, VLAN management and other functions.

5. It is necessary to divert traffic flow to different terminals of the Intranet;

6. Web management is required for switches in the important part of Intranet.

7. The layer 3 core switch is required.

8. Need to provide fiber port for aggregation to data transmission.

ONV Solution

1. From access layer, aggregation layer to core layer, choose ONV switch series, special for video transmission, which is full of the features of large data processing ability, store and forward which can support the line speed forward efficiency, big buffer design, priority mechanism of video streams transmission, transmission for long frame and data traffic management etc. With above switches, it improves whole system’s performance to huge amounts of video and data transmission.

2. Choose ONV PoE switch for access layer, it simplifies the complicated power supply structures, no need to equip power supply to terminal devices. What’s more, it shortens the project construction lead time and saves the cost. And also can improve the system stability, safety and energy saving efficiency etc.

3. Model details for access layer, 16/24*PoE ports + 2*gigabit fiber ports PoE switch. Then use the gigabit fiber port to aggregation from access layer to aggregation layer. And use 10G fiber port to aggregation from aggregation layer to core layer. Choose ONV 24*Gigabit fiber ports + 4*10G fiber ports full fiber ports series switch as the aggregation switch and 24*10/100/1000M RJ45 ports + 4*10G fiber ports Layer 3 Managed switch as the core switch. The layout of whole campus video monitoring network transmission adopts fiber cable, and the switch is suggested to choose fiber switch to reduce the use of the fiber media converter. It also reduces the failure node and improves system efficiency.

4. All ONV aggregation switch and core switch support smart web management, looped network detection, port dynamic aggregation, MSTP and broadcast storm relieving etc.
