Need for Standards

• make or break networking products

• Interoperability

• Vendor independence is designing or manufacturing products.

• Should have a common ground where manufacturer's obey the standardization

List of Standards

• There are several Standards, but most common ones are

• ISO (International organization of Standardization)

• IEEE (Institute of Electrical and Electronic Engineers)

ISO

• OSI Model is developed by ISO for Networking

• ANSI is the member of ISO that develops standards from programming language to Disk drives

IEEE

• IEEE Society has more than 3 Lakh members

• Computer Soceity of IEEE alone has more than 1 Lakh members

• IEEE 802.2 - 802.5 for wired LAN Standards

802.1 (Bridging)

• Overall picture of LAN and connectivity

• addressing network management

• Standards for Bridges

802.2 (LLC)

• Logical Link Control

• Communication of packets from one device to another device.

• It deals with communication

802.3(Ethernet)

• Ethernet Mainly

• CSMA/CD

• Speed of 10MB/s

• 802.4 is Token bus and it is disbanded

802.5 (Token Ring)

• Token Ring

• Speed of 4Mbps or 16Mbps

802.7 .8 .9 .10

• 802.7 - Broadband LAN and it is withdrawn

• 802.8 (Fiber optic cabling and access methods)

• 802.9 (Voice and digital data integration)

• 802.10 (interoperable security)

802.11 (Wi Fi)
