Abstract
A communication scheme capable of guaranteeing the order of packets in the communication media exchange during the communication so as to be able to continue the communication smoothly even after the communication media exchange is disclosed. The source host transmits a first check packet through the first communication path and stops transmission of user data packets upon transmitting the first check packet, while the destination host transmits the first check packet through the second communication path upon receiving the first check packet through the first communication path while transmitting a second check packet through the first communication path, and stops transmission of user data packets upon transmitting the second check packet. Then, the source host starts transmission of user data packets through the second communication path upon receiving the first check packet through the second communication path, while the destination host starts transmission of user data packets through the second communication path upon receiving the second check packet through the second communication path.
