Description

Technical Field

[0001] The present invention relates to the technical field of hubs, in particular to a multifunctional double-layer hub. Background Art

[0002] A hub is called a "hub." "Hub" means "center." Its primary function is to regenerate, shape, and amplify received signals to extend the network's transmission distance while concentrating all nodes around it. It operates at Layer 1 of the OSI (Open Systems Interconnection) reference model, the "physical layer." Like other transmission media such as network cards and cables, hubs are fundamental components of a local area network (LAN) and utilize the CSMA / CD (Carrier Sense Multiple Access with Collision Detection) media access control mechanism. Each hub interface simply transmits and receives bits, forwarding a 1 if it receives a 1 and a 0 if it receives a 0. No collision detection is performed. As a purely hardware-based network device, a hub lacks the "intelligent memory" or "learning" capabilities of switches. It also lacks the MAC address table found in switches, so data transmission is non-targeted and broadcast. This means that when a hub sends data to a specific node, it doesn't send the data directly to the destination node, but rather sends the data packet to all nodes connected to the hub.

[0003] When the current multifunctional double-layer hubs are combined with each other, the hubs are simply stacked together, and the upper hub is easily broken once it falls off. Summary of the Invention

[0004] The purpose of the present invention is to provide a multifunctional double-layer hub, which solves the problem that the current multifunctional double-layer hubs are only stacked together when combined with each other, and the upper hub is easily broken once it falls off.
