Difference between Flow Control and Congestion Control




  • Main Difference

    Flow Control gets defined as the data flow management between two or more electronic devices to ensure that the data gets handled properly within the timeframe. On the other hand, Congestion Control gets defined as the queueing and networking phenomena that help to identify whenever a node which carries more than necessary data becomes visible.

    Basis of Distinction Flow Control Congestion Control
    Definition The data flow management between two or more electronic devices to ensure that the data gets handled properly within the timeframe. The queueing and networking phenomena that help to identify whenever a node which carries more than necessary data becomes visible.
    Benefit Deals with the traffic and makes sure that all the information flows smoothly between the system. Deals with the errors that arise during the movement of data and therefore may also get referred as a type of error control.
    Location Takes place on the receiver where all the information gets collected at one end and adjust the flood coming from one direction. Takes place on the sender side and detects the congestion of network based on time and along with other features.

    Flow Control

    Flow Control gets defined as the data flow management between two or more electronic devices to ensure that the data gets handled properly within the timeframe. It gives an instrument to the collector to control the transmission speed so that the getting hub does not get overpowered with information from transmitting hub. Stream control ought to get recognized from clog power, which gets utilized for controlling the flow of information when a blockage has happened. Flow control systems can get ordered by regardless of whether the accepting hub sends criticism to the sending hub. Flow control is imperative since it is workable for a sending PC to transmit data at a speedier rate than the goal PC can get and handle it. This action can happen if the getting PCs have a substantial activity stack in contrast with the sending PC, or if the accepting PC has less handling power than the sending PC. The shut circle stream control instrument is described by the capacity of the system to report pending system blockage back to the transmitter. This data is then utilized by the transmitter in different approaches to adjust its action to existing network conditions. ABR employs shut circle stream control. An excessive amount of information landing before a gadget can deal with it causes information flood, which means the information is either lost or should get retransmitted. The system gets more complicated whenever the user has to manage large amounts of information and therefore requires other entities.

    Congestion Control

    Congestion Control gets defined as the queueing and networking phenomena that help to identify whenever a node which carries more than necessary data becomes visible. Network Congestion in information organizing and queueing hypothesis is the diminished nature of administration that happens when a system hub is conveying a large number of information than it can deal with. Average impacts incorporate queueing delay, bundle misfortune or the hindering of new associations. A result of the clog is that an incremental increment in offered stack leads either just to a little increase or even an abatement in system throughput. Organize conventions that utilization forceful retransmissions to make up for bundle misfortune because of clog can build blockage, even after the underlying burden has decreased to a level that would not ordinarily have actuated system clog. Such systems display two stable states under a similar degree of load. The steady state with low throughput is known as congestive fall. Systems utilize blockage control and clog shirking strategies to attempt to stay away from fall. These include exponential backoff in conventions, for example, 802.11 CSMA/CA and the first Ethernet, window lessening in TCP, and reasonable queueing in gadgets, for example, switches. Another technique is to actualize need plans, transmitting a few bundles with higher need than others. It does have other types such as closed loop and open loop and both help to manage the system properly and identify the errors that arise with the excess of information.

    Key Differences

    • Flow Control gets defined as the data flow management between two or more electronic devices to ensure that the data gets handled properly within the timeframe. On the other hand, Congestion Control gets defined as the queueing and networking phenomena that help to identify whenever a node which carries more than necessary data becomes visible.
    • Flow control tries to deal with the traffic and makes sure that all the information flows smoothly between the system, on the other hand, congestion control deals with the errors that arise during the movement of data and therefore may also get referred as a type of error control.
    • Flow control takes place on the receiver where all the information gets collected at one end and adjust the flood coming from one direction. On the other hand, congestion control takes place on the sender side and detects the congestion of network based on time and along with other features.
    • Flow control makes sure that the sender only sends the information and the flow stays such that the receiver handles everything without issues. On the other hand, congestion control makes sure that everyone who stays on the network gets enough space and time to perform their tasks.
