You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: Congestion control. The TCP has a certain capacity called transfer window. If we want to send **data** from Point A to Point B we load **data** into the transfer window and wait for an acknowledgement. Point B will send an acknowledge signal telling Point A that all those packets have been received. If we're successful, then the TCP becomes optimistic in the sense that it widens the transfer window so that it can send more **data** at the same time. If the transfer failed for whatever reason, then the transfer window shortens. This produces a slower traffic. TCP makes use of sequence numbering, congestion window and retransmission timer mechanisms to achieve less congestion and reliable service. TCP sender assigns sequence number for every packet sent and expects an acknowledgement before proceeding with further **data** transfer. Congestion window is used to perform congestion control, which keeps track of the number of packets that can be sent by the sender without being acknowledged by the receiving side. Basically, congestion control window decides whether TCP sender is allowed to send packets at any particular instance. TCP accomplishes reliable **data** delivery by deploying retransmission timer mechanism which detects packet loss and retransmits them. If an acknowledgement is not received before the expiry of the retransmission timer, TCP retransmits the packet and triggers congestion control.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
