Working Groups were created to work and write standards and are open to anyone to participate. They strive for broad representation of all interested parties and encourage global participation. IEEE standards have a comprehensive listing of working groups but not all have public viewable websites. I will focus on the Information Technology working group with the sub-directory of Software and Systems Engineering.
The IEEE Computer Society is the largest association for computer professionals in the world and was founded more than 50 years ago. The Software and Systems Engineering Group/Committee mission is to develop and maintain a family of software and systems ...view middle of the document...
IEEE 802 is subdivided into 22 parts that cover the physical and data-link aspects of networking. The better known specifications include 802.3 Ethernet, 802.11 Wi-Fi, 802.15 Bluetooth/ZigBee, and 802.16 (Rouse, 2006).
Ethernet is better known as the granddaddy of the 802 specification. It provides asynchronous networking using CSMA/CD (carrier sense, multiple access with collision detect) over coax, twisted-pair copper and fiber media between the current speed range of 10 Mbps to 10 Gbps. 802.15 is a communications specification that was approved in early 2002 by the Institute of Electrical and Electronics Engineers Standards Association (IEEE-SA) for wireless personal area networks (WPANs). Bluetooth is a well-known and widely used specification that defines parameters for wireless communications among portable digital devices including notebook computers, peripherals, cellular telephones, beepers, and consumer electronic devices. The specification also allows for connection to the Internet.
Standards play an important role in networking. Without standards, manufacturers of networking products have no common ground on which to build their systems. Interconnecting products from various vendors would be difficult, if not impossible. Take for example the 802.3 standard that deals with only Local Area Networks (LAN) and Metropolitan Area Networks (MAN). The LAN switch is a device with multiple inputs and outputs to interconnect multiple numbers of hosts and computing terminals. LAN switch prevents data packet collision, and maximizes transmission speed as well as bandwidth allocation. The core job of the switch is to take packets that arrive on an input and forward (or switch) them to the right output so that they will reach their appropriate destination.
According to Stallings, there are many advantages and disadvantages to the standards-making process. The principal advantages of standards are it allows products from multiple vendors to communicate, giving the purchaser more flexibility in equipment selection and use and it also assures that there will be a large market for a particular piece of equipment or software. The principal disadvantages though are that standards tends to freeze the technology and by the time it is developed, reviewed and compromised, more efficient techniques would have come around. Another disadvantage of standards is that there could be multiple standards for the same thing. Although this is not a disadvantage of standards per se, but more so of the current way things are done. Fortunately, in recent years the various standards-making organizations have begun to cooperate more closely. Nevertheless, there are still areas where multiple conflicting standards exist. (Stallings, 2009)
