Open System Interconnection Why we have to use OSI model? System and Device Design Trouble-shooting OSI model: PHY layer MAC layer Network layer Session layer Presentation layer Application layer Telecomm Dept Faculty of EEE DCN HCMUT OSI Model: Layer Functions Telecomm Dept Faculty of EEE DCN HCMUT Communication in OSI model At each level, two entities (N-entity peers) interact by means of the N protocol by transmitting protocol data units (PDU) A service data unit (SDU) is a specific unit of data that has been passed down from an OSI layer to a lower layer, and which the lower layer has not yet encapsulated into a protocol data unit (PDU) An SDU is a set of data that is sent by a user of the services of a given layer, and is transmitted semantically unchanged to a peer service user The PDU at a layer N is the SDU of layer N1 In effect the SDU is the 'payload' of a given PDU All the data contained in the SDU becomes encapsulated within the PDU The layer N-1 adds headers or footers, or both, to the SDU, transforming it into a PDU of layer N-1 The added headers or footers are part of the process used to make it possible to get data from a source to a destination Telecomm Dept Faculty of EEE DCN HCMUT
