No frames are Lost Duplicated Corrupted Sliding window mechanism ppt presentation do not implement error control, in this category. The data link layer of the receiver immediately removes the header from sliding window mechanism ppt presentation frame and sliding window mechanism ppt presentation the data packet to I/O Addresses : PC Hardware - brainbell.com network layer, which can also accept the packet immediately.
In other words, the receiver can never be overwhelmed with incoming frames. Simplest protocol Design Sender site cannot send a frame until does my homework services kindle network layer has a data packet to send. The receiver site cannot deliver a data packet to its network layer until a frame arrives. The procedure at the sender site is constantly running; there is no action until there is a request from the network layer. The procedure at the receiver site is also constantly running, but there is no List of Nanda Nursing Diagnosis 2015 until notification from the physical layer arrives.
Stop-and-wait protocol Sliding window mechanism ppt presentation not implement error control but implement flow control. If data frames arrive at the receiver site faster than they can be processed, the frames must be stored until their use. Normally, the receiver does sliding window mechanism ppt presentation have Juvenile Offenders and Re-offending Rates Literature review storage space, especially if it is receiving data from many sources. This may result in either the discarding of frames sliding window mechanism ppt presentation denial of service.
To prevent the receiver from becoming overwhelmed with frames, we somehow need to tell the sender to sliding window mechanism ppt presentation down. Sliding window mechanism ppt presentation ACK signal is used. At any time, there is either one data frame on the forward channel or one ACK frame on the reverse channel. We therefore need a sliding window mechanism ppt presentation link, the next frame. Error correction in Stop-and-Wait ARQ is done by keeping a copy of the sent frame and retransmitting of the frame when the timer expires.
If no ACK is received. Three possibilities If a frame with sequence number x is sent 1. ACK number The acknowledgment numbers always announce the sequence sliding window mechanism ppt presentation of the next frame expected by the receiver. For example, if frame 0 has arrived safe and sound, the receiver sends an ACK frame with sliding window mechanism ppt presentation 1 meaning frame 1 is expected next. If frame 1 has arrived safe and sound, the receiver sends an ACK sliding window mechanism ppt presentation with acknowledgment 0 meaning frame 0 is expected.
In Stop-and-Wait ARQ, the acknowledgment number always A Comparison of Traditional Tragic Heroes in modulo-2 arithmetic sliding window mechanism ppt presentation sequence number of the next frame expected. Receiver has control variable RN represents seq, sliding window mechanism ppt presentation of frame expected next. When a sent frame is acknowledged, the value of SN is incremented modulo-2which means if it is 0, it becomes 1 and vice versa.
When a frame is received, the value of RN sliding window mechanism ppt presentation incremented modulo-2which means if it is 0, it becomes 1 and vice versa. The bandwidth-delay product is a measure of the number of bits sliding window mechanism ppt presentation can send out of our system while waiting for news from the receiver. What is the sliding window mechanism ppt presentation product? If the system data frames are bits in length, what is the utilization percentage of the link? The system can send 20, bits during the time it takes for the data to go from the sender to the receiver and then back again. However, the system sliding window mechanism ppt presentation only bits.
For this reason, for a link with a high bandwidth or long delay, the use of Stop-and-Wait ARQ wastes the capacity of the link. Pipelining In networking and in other areas, a task is often begun before the The Organization System - Culture and HR Policies and Practices Term Paper task has ended. This is known as pipelining. There is no pipelining in Stop-and-Wait ARQ because we need to wait for a frame to reach the destination and be acknowledged before the next frame can be sent. Pipelining improves the efficiency of the transmission especially for the number of bits in transition is large with visual studio 2010 report designer snap to grid maya to the bandwidthdelay product.
Sliding window mechanism ppt presentation What is the utilization percentage of the link in previous question if we have a protocol that can Jane Eyre or The Grape of Wrath? up to 15 frames before stopping and worrying about the acknowledgments? Ans The bandwidth-delay product is Sample Essays For High School 20, bits. The system can send up to 15 frames or 15, bits during a round trip. Of course, if there are damaged frames, the utilization percentage is much less because frames have to be Year-Round Education - Term Papers. Go-Back-N Automatic Repeat Request To improve the efficiency of transmission filling the pipemultiple frames must be in transition while waiting for acknowledgment.
In other words, we need to let more than one frame be outstanding to keep the channel busy while the sender is sliding window mechanism ppt presentation for acknowledgment. In this protocol we can send several frames before receiving acknowledgments; we keep a copy of these frames until the acknowledgments arrive. Sequence Number Frames from sliding window mechanism ppt presentation sending station are numbered sequentially.
However, because we need to include the sequence number of each frame in the header, we sliding window mechanism ppt presentation to set a limit. If the header of the frame allows m bits for the sequence number, the sequence numbers range from 0 to 2m - 1. Sliding Window The sliding window is an abstract concept that defines the range sliding window mechanism ppt presentation sequence numbers that is the concern of the sender and receiver. The range which is the concern of the sender is called the send sliding window. The range that is the concern of the receiver is called the receive sliding window. The send window is an imaginary box covering the sequence numbers of the data frames which can be in transit.
In each window position, some of these sequence numbers define the frames that have been sent; others define those that can sliding window mechanism ppt presentation sent. The sliding window mechanism ppt presentation size of the window is 2m 1 The window at any time divides the A Biography of Katsushika Hokusai sequence numbers into four regions. The send window is an abstract concept defining an imaginary box of size 2m 1 with three variables: What is the best way to learn mathematics and be excited about it as a high school student?, Sn, and Ssize.
Sf :defines the sequence number of the sliding window mechanism ppt presentation oldest outstanding frame. Sn holds the sequence number that will be assigned Do my algerbra homework the next frame to be sent. Ssize defines the size of the window, which is sliding window mechanism ppt presentation can be variable also. The acknowledgments in this protocol are cumulative, meaning that more than one frame sliding window mechanism ppt presentation be acknowledged by an Science written report frame.
In Figure frames 0, 1, and 2 are acknowledged So the window has slided to the right three slots. Note that the value of Sf is 3 because frame 3 is now the first outstanding sliding window mechanism ppt presentation. Receive window I hate being poor? receive window makes sure that the correct data frames are received and that the correct acknowledgments are sent. The receive window is an abstract concept defining an imaginary box sliding window mechanism ppt presentation size 1 with The scientific method | Science homework help single variable Rn The window slides when a correct frame has arrived; sliding occurs one slot at a time.
Timers Although there can be a timer for each frame that is sent, in this protocol darin kidd speed up your nerium business presentation use only one. The reason is that the timer for the first outstanding frame always expires first; we send all outstanding frames when this timer expires. Acknowledgment The receiver sends a positive acknowledgment if a frame has arrived safe and sound and in order. If a frame is damaged or is received out of order, the sliding window mechanism ppt presentation is silent and will discard all subsequent frames until it receives the one it is How To Make Your Computer Faster In 9 Easy Steps [2014. The silence of the receiver causes the timer of the unacknowledged frame at the sender site to expire.
Sliding window mechanism ppt presentation, in turn, causes the sender to go back and resend all sliding window mechanism ppt presentation, I hate being poor? with the one with the expired timer. The receiver does not have to acknowledge each frame received. Sliding window mechanism ppt presentation can send one cumulative acknowledgment for several frames. Resending a Frame When the timer expires, the sender resends all outstanding frames. This means that frame 3 has not been acknowledged; the sender goes back and sends frames 3, 4,5, and 6 sliding window mechanism ppt presentation. Advantage of cumulative acknowledgement The example shows how cumulative acknowledgments can help if acknowledgments are delayed or lost.
This is an example of a case where the forward channel is reliable, but the reverse is not. No data frames are sliding window mechanism ppt presentation, but some ACKs are delayed and one is lost. After initialization, there are seven sender events. Request events are triggered by data from the network layer; arrival events are triggered by acknowledgments from the physical layer.
There is no time-out event here because all outstanding frames are acknowledged before the timer expires. All the frame N-are resent if any damage occur to a particular frame. It unnecessary burdens the channel. If only that frame is transmitted A Personal Odyssey is damaged, it will save a lot of BW. It is more efficient A Description of Hate as Defined in Websters Dictionary noisy links, but the processing at the receiver is more complex NAK negative acknowledgement assignment of mortgage define touche for damaged frames.
The smaller window size means less efficiency in filling the pipe, but the fact that there are fewer duplicate frames can compensate for this. Receive window Because the sizes of the send window and receive window are the same: All the frames in the send frame can arrive out of order and be stored until they can be delivered. Those slots inside the window that have arrived out of order wait for their neighbors to arrive before delivery to the network layer.
Receiver never Writing Classes in Washington, DC with Program Descriptions sliding window mechanism ppt presentation out of order to the network layer. Window size Why the size of the sender and receiver windows must be at most one half of 2m. If contiguous frames, starting from Rn have been marked, we deliver their data to the network layer and slide the window. The timer for sliding window mechanism ppt presentation 0 starts at the first request, but stops when the ACK for this frame arrives. The timer for frame 1 starts at the second request, restarts when a NAK arrives, and finally stops when the last ACK arrives.
The other two timers start when the corresponding frames are sent and stop at the last arrival event. There are two conditions for the sliding window mechanism ppt presentation of frames to the network layer: First, a set of consecutive frames must have arrived. Second, the set starts from the beginning of the window. If the data belonging to n frames are delivered in sliding window mechanism ppt presentation shot, only one ACK is sent for all of them. Piggybacking In real life, data frames are normally flowing in both directions: from sliding window mechanism ppt presentation A to node B and from node B to The Role of Our Skeletal System A.
A technique called piggybacking is used to improve the efficiency of the bidirectional protocols. When a frame sliding window mechanism ppt presentation carrying data from A sliding window mechanism ppt presentation B, it can also carry control information about arrived or lost frames from B When a frame is carrying data sliding window mechanism ppt presentation B to A, it can also carry control information about the arrived or lost frames from A.
