Transport Layer

Vocabulary flashcards based on the lecture content about the transport layer in network protocols.

Transport Layer

Responsible for delivering data with the desired reliability end-to-end between two application processes.

Connection-oriented service

A service that requires establishing a connection before data can be exchanged, such as TCP.

Well known port

Port numbers from 0-1023 assigned to standard services that systems offer.

3-way handshake

A method used to establish a connection, involving a sequence of connection requests and acknowledgments between hosts.

Socket

A combination of an IP address and a port number that identifies a process on a host.

UDP (User Datagram Protocol)

An unreliable, connectionless transport protocol that does not guarantee delivery or order of packets.

TCP (Transmission Control Protocol)

A connection-oriented transport protocol that provides reliable byte stream transmission.

Congestion window

A window maintained by the sender that indicates the amount of data the network can handle.

Flow control

Mechanism to manage the rate of data transmission between sender and receiver to prevent overwhelming the receiver.

Sliding window protocol

A method used in TCP that allows multiple packets to be in transit before needing acknowledgment.

Transport Protocol Data Unit

A segment; the unit of data passed over the transport layer.

Error control

Techniques used to detect and correct errors in transmitted data.

Disconnection

The process by which an established connection is terminated between hosts.

Sequence number

A number assigned to packets that allows the recipient to arrange data in the correct order.

ACK (Acknowledge)

A signal sent by the receiver to indicate receipt of a packet.

NSAP (Network Service Access Point)

An address used to identify a transport entity within a network.
