Abstract
Disclosed are an apparatus and a method for swapping headers for authenticating policy based domains and tracing paths at the time of high-reliable data plane transmission. The method includes receiving packets forwarded through predetermined paths, confirming whether the received packets are normal packets, determining whether the path identification information corresponding to the paths of the received packets is present in a header information storage unit of a domain receiving the packets, swapping the headers included in the packets to swapping headers of the header information storage unit by using the identification information if it is determined that the path identification information is present, and correcting the path tracing information. By this configuration, degradation in data plane performance due to the lengths of headers can be solved.
