This layer usually incorporates Layer 2 switches and access points that provide connectivity between workstations and servers. You can manage access control and policy, create separate collision domains, and implement port security at this layer. For example, a switch that provides access-layer functionality is called an access switch, a switch that operates in the distribution layer is known as a distribution switch, and a switch that operates in the core layer is called a core switch. This layer serves as the network's outermost boundary and the gateway through which all data must pass. Selecting the right switch type has a direct impact on network scalability, performance, and management efficiency.
[pdf] The scope of this report encompasses the global Ethernet switch and router market, with a specific focus on H3C's core segments: Data Center Switching, Enterprise Campus Networking, and AI-native infrastructure. H3C campus switches integrate the multi-ability of AC, SDN, PON and Security. For intelligent ultra-wideband cloud data center, full-scenario data center products and solutions are created for scale, intelligence, and visualization. H3C has been deeply engaged in the campus network for many years. With a range spanning ten series and hundreds of switches, H3C's options can cover your networking needs – from the data center core to campus access and remote branches. It summarizes key products such as AD-NET switches, routers, wireless solutions and iMC cloud management platform that help.
