In the OSI model, we know that traditional network switches operate at Layer 2 while network routers operate at Layer 3. Besides, switches are understood to be forward traffic based on MAC address, while routers perform the forwarding based on IP address. Layer 3 switches have a lot in common with traditional routers: they can also support the same routing protocols, inspect incoming packets and make dynamic routing decisions based on the source and destination addresses inside. For this reason, many networking beginners are puzzled over the definition and purpose of a Layer 3 switch. So what is on earth Layer 3 switch and how is it different from router? Layer 3 Switch Layer 3 switch is also called multilayer switch. It is a specialized hardware device used in network routing, which is conceived as a technology to improve network routing performance on large local area networks (LANs) like corporate intranets. A Layer 3 switch is both a switch and a router. So Layer 3 switch i...

Today, all plants are virtually networked via Ethernet. High requirements are placed on the network infrastructure and network components. Ethernet switches are the integral piece of IT infrastructure, capable of receiving, processing and transmitting data between two devices connected by a physical layer. Due to the increasing application of big data analytics and cloud-based services in various end-user segments, data centers are envisaged to fuel the adoption of Ethernet switches. The augmented global demand for data centers is the key driver for the growth of Ethernet switches market. To satisfy the large and ever-increasing market for Ethernet switches, there are many varieties of switches offered different purposes. This article will help you get a deep understanding of the different types of Ethernet switches. What is an Ethernet Switch? A Ethernet switch is a tool for connections between the systems and equipment to forward data selectively to one or more connected d...
