High density Switches and connector are the new stimulant for connectivity

By: Mannu Mathew | Sub Editor | ELE Times

Switches and connector facilitate the sharing of resources by connecting together all the devices, including computers, printers, and servers, in a small business network. The networking marketplace saw dramatic increases in desktop computing power. As application programs grew in complexity and sophistication, the need to send large quantities of data as quickly as possible grew proportionally. The shared-media environment forced all of these communicators to compete with each other for the use of the media.

Network switches examine each data packet and process it accordingly. In this regard, they are more able than another type of network connection called a hub. A hub simply repeats the signal it sees on one port to all the others that contain connections. All nodes connected to a hub see the same traffic. There is no intelligence behind either the data transmission or the determination of which node receives packets.

Switches and Connectors reduce network congestion

Most switches are self-learning. They determine the Ethernet addresses in use on each segment and build a table as they pass packets. When the switch receives a frame, it saves the MAC address of the originator and remembers the port on which the frame arrived. This plug-and-play element makes switches an attractive alternative to hubs.

Switches can connect different network types or networks of the same type. Many switches today offer high-speed links, like Fast Ethernet, which can be used to link the switches together or to give added bandwidth to important servers that get a lot of traffic. A network composed of several switches linked together via these fast uplinks is called a collapsed backbone network.

Switches are perhaps three to five times more expensive. Nevertheless, the market for Ethernet switches has been doubling annually. The reason is switch prices have been dropping precipitously, while hubs are a mature technology with small price declines. This means there is far less difference between switch costs and hub costs than there once was, and the gap is narrowing.

Advanced Switching is now possible to find what are called managed switches that are designed for industrial networks. Managed switches are increasingly used in networks containing time-critical devices or where it is important to know immediately when the network has problems. Managed switches often can generate real-time warnings for notable events such as power on/off, traffic overload, configuration changes, and so forth.

Switches generally serve to ease congestion on busy networks. But it is possible to deploy switches in ways that either make traffic worse or fail to improve the situation. A better approach would be to replace the Ethernet segment between the switch and the server with a Fast Ethernet connection. Use of Fast Ethernet in the center of a client-server network almost always relieves network congestion.

Switches and connectors play a crucial role in modern day connectivity

A hybrid device is the latest improvement in internetworking technology. Combining the packet handling of routers and the speed of switching, the multilayer switches operate on both layer two and three (data link and network) of the network model. It is also this layer that controls how a computer on the network gains access to network data and gets permission to transmit it, as well as handles frame synchronization and error checking. Let us have a look at the latest switches and connectors in the market.
