Abstract:
A method of transferring fragmentation message, a system of communication and
a tunnel device are disclosed and are used to make fragmentation message to traverse
NAT or firewall device. The method includes: The first tunnel device receives
IP fragmentation message and converts the IP fragmentation message to non-fragmentation
message. The first tunnel device transfers the non-fragmentation message to
the second tunnel device through a UDP tunnel. The system includes the first tunnel
device, the second tunnel device and the UDP tunnel which connects the first tunnel
device with the second tunnel device. The first tunnel device receives IP fragmentation
message, converts the IP fragmentation message to non-fragmentation message
and then transfers the non-fragmentation message to the second tunnel device
through the UDP tunnel. The second tunnel device receives the message from the
first tunnel device. A tunnel device is also provided. Fragmentation message
traversing firewalls is implemented.
