怎麼選擇核心交換機

大中型的監控網絡，通常會按照接入-匯聚-核心三層結構設計。核心交換機是整個網絡的數據轉發中心，承載著大量的數據流，所以必須保證核心交換機的各個埠轉發沒有瓶頸。

怎麼選擇核心交換機?

選擇核心交換機時，應根據IPC數量，如：

①100~200台，推薦千兆管理型交換機

②200~500台，推薦三層管理型交換機

目前二/三層管理型全千兆交換機，均適合作為監控網絡的核心交換，承擔大容量數據交換。組建各樣的網絡。對於大型或超大型的監控網絡，需要使用三層交換機劃分網段，建議使用三層交換機。

How to choose a core switch?

Large and medium-sized monitoring networks are usually designed according to the three-layer structure of access-convergence-core. The core switch is the data forwarding center of the entire network and carries a large number of data flows. Therefore, it is necessary to ensure that there is no bottleneck in the port forwarding of the core switch.

How to choose a core switch?

When selecting a core switch, it should be based on the number of IPCs, such as:

①100 ~ 200 units, recommended Gigabit managed switches

②200 ~ 500 units, three-layer managed switches are recommended

At present, the Layer 2 / Layer 3 managed full Gigabit switches are suitable as the core exchange of the monitoring network and undertake large-capacity data exchange. Build various networks. For large or very large monitoring networks, you need to use layer 3 switches to divide the network segment. Layer 3 switches are recommended.
