Planes in Networking

Type of Planes in Networking Conventionally speaking, we have three planes in any network device (routers, switches, etc.) viz. Control Plane, Data Plane, and Management Plane But, there exists one more plane, that is, Service Plane. The reason, why you won't find this plane mentioned in your textbooks, is because the term Service plane was officially coined very recently. We will discuss about this later in the section below. First, let's get started with the three conventional planes. Control plane and Data plane: Let's say you have three PCs (A, B, and C) connected over a switch(S) at your home and you want to send some bits/bytes of data (also called payload) from A to B. So this data (or payload) will be in the Data Plane of the switch S.  Now, the switch S has to direct the packet, which contains the payload, to the port on which B is connected. To achieve this delivery of the packet, the switch S generates some bytes of data which control the jo...

Ethernet and Serial technologies

Technology : It serves as a platform for the implementation of innovation. For communication in Networking, there are two main technologies to focus on: Ethernet and Serial Ethernet Technology : Long distance, very high Bandwidth, cheaper in cost. Standard: IEEE 802.3 (wired), IEEE 802.11 (wireless) Protocol of Ethernet technology: ARPA Serial Technology: very long distance, high Bandwidth, expensive. Ethernet variants: Ethernet: 10 Mbps Fast Ethernet: 100 Mbps Gigabit Ethernet: 1000 Mbps Ten Gigabit Ethernet: 10,000 Mbps and so on. Ethernet Mediums: Twisted Pair Thin wire Thick wire Range (meters) 100 180-200 500 BW (Mbps) Upto 1000 10 10   When using Cu wire as a medium, signals travel as EM waves and have ...
