Flow control (data)¶
In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver.
Core Idea¶
Flow control (data) is treated here as the recurring computerscienceandinformation identity summarized by this source-grounded definition: In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver. In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver. Flow control should be distinguished from congestion control, which is used for controlling the flow of data when congestion has actually occurred.
Scope of Application¶
-
Stop-and-wait. In this method the message is broken into multiple frames, and the receiver indicates its readiness to receive a frame of data.
-
Pros. The only advantage of this method of flow control is its simplicity.
-
Sliding window. A method of flow control in which a receiver gives a transmitter permission to transmit data until a window is full.
-
Go back N. An automatic repeat request (ARQ) algorithm, used for error correction, in which a negative acknowledgement (NACK) causes retransmission of the word in error as well as the next N–1 words.
-
Go back N. If it is less than 2a + 1 then the equation must be used to compute utilization.
Clarity¶
A clear use of Flow control (data) names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver.
Manages Complexity¶
Flow control (data) compresses multiple computerscienceandinformation details into a stable diagnostic relation. The source shows both the central mechanism—the window maintained by the sender indicates which frames it can send.—and the practical consequence—either by control signal lines in a data communication interface (see serial port and RS-232),. This compression makes cases comparable while leaving parameters, conventions, exceptions, and evidential quality explicit.
Abstract Reasoning¶
- Type the carrier. Identify the computerscienceandinformation entities to which the claim applies.
- State the relation. Use the source-grounded identity: In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver.
- Check operation and conditions. An automatic repeat request (ARQ) algorithm, used for error correction, in which a negative acknowledgement (NACK) causes retransmission of the word in error as well as the next N–1 words. 4.
Knowledge Transfer¶
Within the home domain. Knowledge about Flow control (data) transfers literally when a new case preserves the same carrier type, relation, and recognition test. In this method the message is broken into multiple frames, and the receiver indicates its readiness to receive a frame of data. The only advantage of this method of flow control is its simplicity. Beyond the home domain. No canonical parent is asserted for Flow control (data).
Neighborhood in Abstraction Space¶
Flow control (data) sits in a moderately populated region (50th percentile for distinctiveness): it has near-neighbors but no dense thicket of look-alikes.
