Zusammenfassung:PROBLEM TO BE SOLVED: To provide an IP datagram encapsulation method for transferring an IP datagram through an SDH/SONET transmission path, without lowering transfer efficiency and an IP processor for executing it. SOLUTION: Only a flag 101 is added to the IP datagram. An octet '01111110' which matches a synchronous code pattern is replaced with the two octets of '01111101-01011110' and the octet '01111101' matched with an escape code pattern is replaced with the two octets of '01111101-01011101' for the IP datagram 100 to enable flag synchronization. The escaped IP datagram, to which the flag 101 of the synchronous code pattern is added, is inserted to a SDH/SONET transmission path 200.
