Study Notes
Transport Layer Protocols
- The two main protocols in the transport layer are TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
Error Control in Data Transmission
- Error control in data transmission is responsible for detecting and correcting errors that occur during data transmission.
Port Mapper
- The main function of a port mapper is to map a process or process instance to a transport layer connection endpoint.
Flow Control in the Transport Layer
- The role of flow control in the transport layer is to prevent the sender from overwhelming the receiver with data.
TSAP
- TSAP stands for Transport Service Access Point.
Store-and-Forward Packet Switching
- Store-and-forward packet switching is a technique where a packet is received in its entirety, stored, and then forwarded to the next hop.
Network Layer Services
- The network layer offers the following services to the transport layer: routing, congestion control, and fragmentation.
Router Technology Independence
- The services provided by the network layer should be independent of router technology to ensure that the transport layer can operate with different router technologies.
Shielding the Transport Layer
- The goal of shielding the transport layer from the number, type, and topology of routers is to allow the transport layer to operate independently of the network infrastructure.
Uniform Numbering Plan
- Network addresses available to the transport layer should use a uniform numbering plan to enable the transport layer to route data packets efficiently.
