GGP Billet Receivers are precisely machined from 7075-T6 Aluminum for a perfect fit. Not only can you build your own version of the Heavy or Light rifle, but you can use your favorite aftermarket parts to complete the weapon of your dreams. This is achieved: the receiver process keeps track of the sequence number of the earliest frame it has not received and sends the respective sequence number with the acknowledgement signal.The new MKII version of the GGP-P Series brings a new level of customizability never before seen in our rifle receivers. Selective Repeat ARQ/Selective Reject ARQ protocol mechanism is similar to the Go-Back-N protocol mechanism but in Selective Repeat ARQ the sending process continues even after a frame is found to be corrupt or lost. Selective Repeat ARQ/Selective Reject ARQ:.This protocol is more efficient than Stop and wait ARQ as there is no waiting time. The only drawback of this type of system is that it results in sending packets multiple times: if any frame was lost or found to be corrupted, then that frame and all following frames in the send window will be re-transmitted. Once the sender has sent all of the frames in its window, it will identify that all of the frames since the first lost frame, and will go back to the sequence number of the last acknowledgement signal that it received from the receiver pr and continue the process over again. There are only two possibilities that a frame won’t match the sequence number: it is either a duplicated frame of an existing frame or an out-of-order frame that needs to be sent later, the receiver recognizes this scenario and sends an acknowledgement signal accordingly. The receiver will remove any packet that does not have the desired sequence number it expects and will resend an acknowledgement for the last correct frame. The receiver process keeps track of the sequence number of the next packet it expects to receive and sends that sequence number with every acknowledgement to the sender. Go-Back-N ARQ is a type of the ARQ protocol, in which the sending process continues to send several frames or packets even without receiving an acknowledgement packet from the receiver. The above scenario depicts a Stop and wait situation, so this control mechanism is termed as Stop and wait ARQ. The timeout is reset after each frame transmission. If the acknowledgement does not reach the sender before the specified time, known as the timeout, the sender sends the same packet again. After receiving the desired frame, the receiver sends an acknowledgement. Moreover, the sender keeps a copy of the sent packet. After sending a frame or packet, the sender doesn’t send any further packets until it receives an acknowledgement from the receiver. It is referred to as stop and wait ARQ because the function of this protocol is to send one frame at a time. Stop and wait ARQ is also referred to as the alternating protocol is a method used in two-way communication systems to send information between two connected devices (sender and a receiver). There are several types of ways in which these protocols function in the data link layer : ![]()
