    Abstract: A system and method are described for detecting packet loss using an error checking signature, such as a cyclical redundancy check (CRC), while transmitting packets between a sender and a receiver. A counter is present on both the sender and the receiver, the two counters initially synchronized with each other. The CRC is generated using a sequence number provided by the counter at the sender. As the packets are sent, the sender counter is incremented. The receiver uses a sequence number from the receiver counter to decode the CRC. If all the packets are received, the sequence number to decode should match the sequence number to encode. Therefore, if the CRC does not decode properly, a packet has been lost or corrupted. A message to resend the packets is sent to the sender. The receiver counter is not incremented until the proper packet is received and decoded.

    Abstract translation: 描述了一种系统和方法,用于在发送方和接收方之间传送分组时使用错误校验签名(例如循环冗余校验(CRC))来检测分组丢失。 发送方和接收方都有计数器,两个计数器最初是相互同步的。 CRC是使用发件人柜台提供的序列号生成的。 当数据包被发送时,发送者计数器递增。 接收器使用来自接收器计数器的序列号来解码CRC。 如果接收到所有数据包,则要解码的序列号应与要编码的序列号相匹配。 因此,如果CRC未正确解码,则数据包丢失或损坏。 将重发数据包的消息发送给发件人。 接收器计数器不会递增,直到收到并解码正确的数据包。
