TCP Flags – Urgent Pointer Previously we had seen that every flag denotes some purpose. Urgent Flag or Urgent Pointer is one such flag. As the name itself suggest that something urgent to be sent for the receiver. With the help of an example, we can see the behaviour of Urgent Pointer. A host wanted to sent the message to a destination application which is at a remote location. If it appears that there is a problem, the host will stop the data transfer. For this, the host will send the abort signal. In normal situation, this signal will be queued at the remote host till all the previous data is processed. With the help of urgent pointer, the host will sent this abort signal without waiting in the data que. The Urgent Pointer flag is set to “1”. This number denotes the position of the segment. And thus, the data is transmitted quickly. #vitinstitute, @
