MOBILE COMPUTER DEVICE AND PACKET PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a mobile computer device more efficient in reception processing without securing an extra buffer or the like in the case of executing the decapsulation processing of a received capsulated packet by using a buffer area where the capsulated packet is stored as it is and executing a overriding processing. SOLUTION: When a capsulated packet arrives at a mobile computer 20, it is decapsulated in a packet processing part 3. In the mobile computer device, a buffer area part applying to the first packet header of the capsulated packet is overridden by the contents of the buffer area part applying to the second packet header in a state where the capsulated packet is stored in the buffer area for a decapsulation processing. Then a part to be invalidated within the buffer area part applying to the second packet header or the buffer areas applying to the first and second packet headers is overridden by prescribed data corresponding to option data of the first packet header.
