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
