Abstract:
1. A packet transmitting method for transmitting packets from a sender node to a receiver node through a network, comprising the steps of: determining by a communication apparatus provided at the sender node, whether each non-compressed packet to be transmitted is an important packet, on the basis of a header, a timestamp, or size of each non-compressed packet; converting by the communication apparatus provided at the sender node, each non-compressed packet which is determined to be an important packet into a refresh-header packet, the refresh-header packet including a refresh header, the refresh header including enough information to recover synchronization in the receiver node; and transmitting a packet stream containing the refresh-header packet and a header-compressed packet to the receiver node, the header-compressed packet including a compressed header, the compressed header including less information than the refresh header.
