Block Acknowledgment Block Acknowledgment BA was initially defined in IEEE 802.11e as an optional scheme to improve the MAC efficiency. Recently ratified amendment 802.11n enhances this BA mechanism then made it as mandatory to support by all the HT devices. IEEE 802.11n capable devices also referred as High Throughput HT devices. Instead of transmitting an individual ACK for every MPDU, multiple MPDUs can be acknowledged together using a single BA frame. Block Ack BA contains bitmap size of 64 16 bits. These 16 bits accounts the fragment number of the MSDUs to be acknowledged. Each bit of this bitmap represent the status success failure of a MPDU. Block Acknowledgment consist of a setup and tear down phases. In the setup phase, capability information such as buffer size and BA policy are negotiated with the receiver. Once the setup phase completed, the transmitter can send frames with out waiting for ACK frame. Finally BA agreement is torn down with DELBA frame. Block Ack policies 1. HT Immediate BlockAck 2. HT Delayed BlockAck The frames used in these agreements are BAR Block Acknowledgement Request To request an acknowledgement to the recipient station, confirming that has received a block of frames. and BA Block Acknowledgement response BA Variants Normal Block Ack Compressed Block Ack It is an enhanced version of BA defined in 802.11n. In compressed BA, Fragmented MPDUs cannot be transmitted and hence the bitmap size is reduced from 1024 64 16 bits to 64 64 1 bits. Multi TID Block Ack This scheme is applicable only with power save operation. Previously described BA variants are capable of acknowledging a single TID. The confirmation from the recipient station, stating which frames have been received, this is explicitly mentioned in a matrix part of the BAR call the bit map .

Unreferenced date December 2009 Orphan date December 2009 Piggybacking is a bi directional data transmission technique in the network layer OSI model . It makes the most of the sent data frames from receiver to emitter, adding the confirmation that the data frame sent by the sender was received successfully ACK acknowledge . This practically means, that instead of sending an acknowledgement in an individual frame it is piggy back ed on the data frame. Working Principle Piggybacking data transfer is a bit different from Sliding Window Protocol used in the OSI model. In the data frame itself, we incorporate one additional field for acknowledgment called ACK . Whenever party A wants to send data to party B, it will send the data along with this ACK field. Considering the sliding window here of size 8 bits, if A has received frames up to 5 correctly from B , and wants to send frames starting from frame 3, it will send ACK6 with the data. Three rules govern the piggybacking data transfer. If station A wants to send both data and an acknowledgment, it keeps both fields there. If station A wants to send just the acknowledgment, then a separate ACK frame is sent. If station A wants to send just the data, then the last acknowledgment field is sent along with the data. Station B simply ignores this duplicate ACK frame upon receiving. Advantages and Disadvantages Advantages Improves the efficiency Disadvantages The receiver can jam the service if he she has nothing to send. This can be solved by enabling a counter Receiver Timeout telecommunication timeout when a data frame is received. If the count ends and there is no data frame to send, the receiver will send an ACK control frame. The sender also adds a counter Emitter timeout , if the counter ends without receiving confirmation, the sender assumes packet loss , and sends the frame again.

multiple issues tone March 2010 unreferenced March 2010 wikify March 2010 confusing November 2011 TCP delayed acknowledgment is a technique used by some implementations of the Transmission Control Protocol in an effort to improve network performance . However, in some circumstances it can in fact reduce performance. The socket level tries to guess what the application level is doing, in order to manage communications efficiently. Often it guesses wrong. If the socket layer immediately acked everything, this would result in a lot of wasted acks, as usually the application sends a response shortly after receiving something, so we would be issuing two acknowledgments, one from the socket layer, one from the application layer. So the socket layer waits one or two hundred milliseconds, and if there is still nothing to send, sends an ack. Unfortunately, the socket layer at the other end, the TCP stack at the other end, may well be waiting for an ack see Nagle s algorithm . If the socket layer at the other end has less than a full packet to send, well, it does not want to send unnecessarily small packets, so it waits a bit in the hope of having more data to send. It waits until it gets an ack for the data it has already sent. This can result in a brief delay. Bob is sending stuff to Carol Bob s socket layer has less than a complete packet remaining to send. It will not be sent till he gets ack for the data already sent. Carol s application layer will not send a response till it gets all the data. Carol s socket layer will not send an ack until it times out, or Carol makes a response. If we are transmitting files in chunks of a hundred thousand bytes, over a gigabit network, all these two hundred millisecond delays can slow things down a great deal. To prevent this delay, the application layer needs to emulate the socket layer, and keep on sending stuff without waiting for acknowledgment of the last thing it sent.
