How to choose the right core switch for a medium to large enterprise?
Jun 15 , 2024 135

In medium to large networks, core switches are key devices to ensure efficient, stable and secure network operation. Choosing the right core switch not only improves network performance, but also meets future expansion and security needs. So, how to choose the right core switch? All need to pay attention to which aspects?

First of all, core switches are needed to meet the high-performance needs of medium and large enterprises, which usually have a large number of users, devices, and applications that require high bandwidth and low-latency network connectivity. Core switches provide high throughput and low latency to meet the needs of organizations for high-speed data transfer and processing power.


Second, the core switch needs to maintain the stability and reliability of the network of medium and large enterprises, it is a key device in the network architecture, can support redundant design, such as dual power supplies, dual controllers, etc., which can effectively prevent monotonic failures and ensure the high availability of the network.


In addition, the core switch also has a high degree of scalability and network management and control capabilities, has a strong security guarantee, but also to support the complex network topology and enhance business continuity and other advantages, can effectively protect the network from attacks, to ensure data security.


Choosing the right core switch can ensure that the enterprise network carries out fast and effective operation status. So, what cost-effective brands and models should we choose when choosing a core switch?


Cisco and Huawei are two brands that, as industry leaders, have long been the brands of choice for most organizations. In terms of models, Cisco's Catalyst 9600 series and Nexus 9000 series and Huawei's CloudEngine 16800 and S12700 series are excellent core switch products suitable for deployment in medium- to large-sized enterprises, capable of delivering high performance, reliability, and security to support the efficient operation and continuous development of enterprise networks.


In order to allow companies to choose the product can be an in-depth understanding of these models, the following we will be from the characteristics of each model to carry out in-depth analysis.
