Transapp
From Mycomputer Notes
Primary duties of the transport layer are to transport and regulate the flow of information from a source to a destination, reliably and accurataly. Control and reliability are accomplished by:
- Sliding windows
- Sequencing Numbers
- Acknowledgements
Protocols in the transport layer segment and reassemble data sent by upper-layer applications into the same transport layer data stream. The transport layer data streams provides end-to-end transport services. The two primary duties of the transport layer are to provide:
- Flow control
- Reliability
Some basic transport services are as follows:
- Segmentation of upper-layer application data
- Establishment of end-to-end operations
- Transportation of segments from one end host to another
- Flow control provided by sliding windows
- Reliability provided by sequence numbers and acknowledgments
