TAILIEUCHUNG - Lecture Basic network management: Chapter 5 - Trung tâm Athena

Chapter 5 - LAN architecture. After studying this chapter you will be able to: Identify the seven protocol layers of the Open System Interconnection (OSI) Reference Model, discuss the functional attributes of each layer of the Open Systems Interconnection Reference Model, understanding Putting Data on the Cable and Access Methods. | Chapter 5: LAN ARCHITECTURE Objectives Identify the seven protocol layers of the Open System Interconnection (OSI) Reference Model Discuss the functional attributes of each layer of the Open Systems Interconnection Reference Model Understanding Putting Data on the Cable and Access Methods Content Introduction Open Systems Interconnection (OSI) Reference Model How network sends data Access Method Summary Introduction Sending Data Recognize data Divide data into manageable chunks Add information to each chunk Location of data Identify receiver Add timing and error checking Put data on the network and send it Protocols: procedures to send data Introduction (2) To solve the problem of networks being incompatible and unable to communicate with each other, the International Organization for Standardization (ISO) released the Open Systems Interconnection (OSI) reference model in 1984 First standard to describe architecture for dissimilar devices to communicate Best known and widely used Open Systems Interconnection The OSI model organizes communication protocols into seven levels: The Physical Layer The Data Link Layer The Network Layer The Transport Layer The Session Layer The Presentation Layer The Application Layer - All People Seem To Need Data Processing Open Systems Interconnection (2) Packet Assembly & Disassembly Process Layer 7: The Application Layer Topmost layer Window for application processes to access network services User-end interface that support transfer files, access database, e-mail Handles general network access, flow control, error recovery Layer 6: The Presentation Layer Determines format to be used to exchange data Called the network translator Responsible for protocol conversion, translating data, encrypting data Manages data compression Redirector utility operates at this layer Layer 5: The Session Layer Performs name recognition and allows two applications on different computers establish, manage and end a connection (session) Provides .
