What is difference between flow control at data link layer vs transport layer?
Flow control in transport layer ensures the delivery of the message globally, as the two points of connection over this protocol are logically connected. Whereas in data-link layer, the concern is to deliver message locally, as the two points of connection over this protocol are physically connected.
Why is flow control required at both data link and transport layers?
Flow control is design issue at Data Link Layer. It is very essential because it is possible for sender to transmit data or information at very fast rate and hence receiver can receive this information and process it.
Which layer is responsible for flow control of data?
The data link layer
The data link layer is further divided into two sublayers: The Logical Link Control (LLC) sublayer is responsible for flow controls and error controls that ensure error-free and accurate data transmission between the network nodes.
Which feature does the Data Link Layer and transport layer have in common?
Features they have in common: Both layers can provide recovery from transmission errors. Both layers can provide flow control. Both layers can support multiplexing.
What are the different types of flow control?
The most common valve types in flow control industries include:
- Gate valves.
- Globe valves.
- Pinch valves.
- Diaphragm valves.
- Needle valves.
What is flow control discuss various flow control methods to improve the pace of sender and receiver?
Flow control tells the sender how much data should be sent to the receiver so that it is not lost. This mechanism makes the sender wait for an acknowledgment before sending the next data. There are two ways to control the flow of data: Stop and Wait Protocol.

How flow control and error control is done at data link layer?
In this way, flow control will control the rate of frame transmission to a value that can be handled by the receiver. 2. Error Control : The error control function of data link layer detects the errors in transmitted frames and re-transmit all the erroneous frames.
What is data link layer responsible for?
The data link layer is responsible for multiplexing data streams, data frame detection, medium access, and error control. It ensures reliable point-to-point and point-to-multipoint connections in a communication network.
Which two layers provide functionality of flow control how does their work differ?
Network layer provides flow control between routers by ICMP. The end terminals usually do not use the network layer barely. IP does not provide flow control. Transport layer, more specifically TCP provides flow control by a backtracking algorithm while UDP does not.
What are the two sub layers of the data link layer?
The data link layer (Layer 2) of the OSI model actually consists of two sublayers: the Media Access Control (MAC) sublayer and the Logical Link Control (LLC) sublayer. The LLC sublayer deals with addressing and multiplexing. Physical addressing for network connections exists at the data link layer.
What are the three types of flow control?
Buffering, Windowing, and Congestion Avoidance are the three types of flow control that are available.
What is the flow control mechanism of the data link layer?
Both data link layer and transport layer have flow control mechanisms. Only in flow control, it is a basic functionality, where it can use Stop-and-Wait or Sliding Window mechanism. It is basic in the sense that it does not involve any analyses of receiver window or congestion window. It only involves a basic communication between ho
What is the difference between data link layer and transport layer?
One important difference between data link layer and transport layer is that we should think about data link layer from hop-hop perspective while transport layer from end-end perspective. This will help understand all relevant methodologies included in both layers. Both data link layer and transport layer have flow control mechanisms.
What is rate based Flow Control Protocol?
Rate based Flow Control These protocols have built in mechanisms to restrict the rate of transmission of data without requiring acknowledgment from the receiver. This is used in the network layer and the transport layer. Data link layer uses feedback based flow control mechanisms.
What are the different approaches of flow control?
Approaches of Flow Control Flow control can be broadly classified into two categories − Feedback based Flow Control In these protocols, the sender sends frames after it has received acknowledgments from the user. This is used in the data link layer.
