This post is focusing on the transport layer.
From this post, you’re free to know the definition and functions of the transport layer.
What Is the Transport Layer?
What is the transport layer?
In short, the transport layer collects message segments from the app and transmits them to Layer 3.
Then, these segments will be reassembled into a complete message and then passed to layer 7.
The transport layer is also responsible for error correction management and it provides you with quality and reliability.
And it is a connection component that allows reuse.
Now, keep on reading this post fromMiniToolto learn more information about the transport layer.

What Does the Transport Layer Do?
What does the transport layer do?
In the following part, you could know some services provided by the transport layer.
1.Connection-Oriented Communication
The first function of the OSI transport layer is connection-oriented communication.
However, this method has a weakness confirmation is required for each message delivered.
Compared with self-correcting packets, this will increase the considerable web link load.
By assigning numbers to packets, ensure that packets are always delivered in strict order.
3.Data Integrity
The third function of it is data integrity.
Use checksums to ensure data integrity between all delivery layers.
These checksums ensure that the transmitted data is the same as the received data and is not damaged.
it’s possible for you to retransmit lost or damaged data by requesting resends from other layers.
4.Flow Control
The next function of the transport layer is flow control.
Devices at both ends of the connection connection usually cannot understand each others capabilities through data throughput.
The final data sending speed may be faster than the receiving unit can buffer or process the data.
When this happens, a buffer overflow may cause the communication to be completely interrupted.
This kind of internet congestion can affect almost every part of the internet.
In the OSI model, multiplexing is performed in the service layer.
If required, the transport layer allows the transmission of byte-oriented data streams.
Other Protocols
In addition to the transport layer protocol, there are some other protocols.
This post provides some methods to help you fix the error.
