In stop and wait flow control, only one frame at a time can be in transit. But when the bit length of the link is greater than the frame length (a>1), it results in serious inefficiencies.
Inside this blog post we are going to cover What is sliding window protocol with an example, What are the types of sliding window protocol, What is the mechanism of sliding window flow control, What is a sliding window?What is the sliding window protocol with an example?
Sliding window protocol is a data link protocol and is used to assure the reliable and sequential delivery of data packet. This protocol is also used in the Transmission control protocol. Inside this protocol sender can send multiple frames at the same time before receiving the acknowledgment for them.What are the types of sliding window protocol?
Download house flipper game free for pc. There are two types of sliding window protocol, one is Go-Back-N-ARQ, and Selective repeat ARQ.What is the mechanism of sliding window flow control?
Sliding window protocol is a data link protocol and is used to control the flow of data or flow control. This protocol solves the problem of missing data packets during the transmission in the upper layers and makes sure the transmission may occur in order.
By permitting multiple frames to be in transit at the same time as a sliding window protocol, efficiency can be greatly improved.
Now, we see its working. For this, it is assumed that two stations, A and B, are connected by a full-duplex link. For W frames, station B allocates buffer space. Therefore, B can take W frames and A is permitted to transmit W frames without waiting for any acknowledgement.
To keep track of that frames have been acknowledged, a sequence number is labelled for each.
By sending an acknowledgement, B acknowledges a frame which includes the sequence number of the next frame accepted.
This acknowledgement also implicitly announces that B is made ready to receive the next W frames, Starting with the number of specified.
This method can also be used for acknowledging multiple frames. A maintains a list of sequence number which is permitted to send and B maintains a list of sequence numbers which are made to receive every list can be thought of as a window of frames.
The operation is known as sliding window flow control with the use of sliding window protocol.Sliding Window Protocol Selective Repeat
Since the sequence number to be used occupies a field in the frame, it is obviously of bounded size.
As an example, for a 3-bit field, the sequence number can range from 0 to 7. Accordingly, frames are numbered modulo8, which is after sequence number 7, The next number is 0. Generally, the range of sequence numbers is 0 through 2^k-1 for a k-bit field and frames are numbered modulo 2^k.
Sliding window protocol or process is shown in fig1. In this fig a 3-bit sequence number is used, so that frames are numbered sequentially from 0 through 7 and then the same numbers are reused for subsequent frames.
The shaded rectangle shows the frames which may be sent. In this figure, the sender may transmit five frames, starting with frame 0.
Using a sliding window protocol each time a frame is transmitted, the shaded window shrinks. Each time an acknowledgement is obtained, the shaded window increases.
Frames between the vertical bar and the shaded -window have been transmitted but not acknowledged.
The sender must buffer these frames in case they require to be retransmitted.
Actual window size requires not to be the maximum possible size for a given sequence number length. As an example, using a 3-bit sequence number, a window size of 4 could be configured for the station using the sliding window flow control protocol.
Fig 2 shows another example of sliding window protocol. A 3-bit sequence number field and a maximum window size of seven frames are assumed in this example.
In starting, A and B have windows showing that A may transmit seven frames, beginning with frame 0(F0).
After sending three frames (F0, F1, F2) without acknowledgement, A has shrunk its window to four frames and a copy of three transmitted frames are maintained by it.
The window shows that A may transmit four frames, starting with frame number 3. Sliding Window Protocol Program In C
Then B sends an RR(receive ready)3, that means “All frames up through frame number 2 have been received by me and I am ready to receive frame number 3”.
With this acknowledgement, A is back up to permission to send seven frames, still starting with frame 3.
A may also discard frames which now been acknowledged using a sliding window protocol.
Proceeds for transmitting frames 3,4,5 and 6. B returns RR4 that acknowledges F3 and permits transmission of F4 through the next instance of F2.
By the time this RR reaches A, It has already transmitted F4, F5 and F6, and thus A may only open its window to allow sending four frames starting with F7.
Sliding window flow control is potentially much more efficient in comparison to stop and wait for flow control.
The reason behind is that, with sliding window flow control, the transmission link behaves like a pipeline which may be filled with frames in transit. On the other hand, only one frame may be in the pipe at a time.Conclusion:
