Abstract:
1. A method for sending a data packet through an intermediate communication network that uses internal routing incompatible with the data packet, the method comprising: receiving an original data packet characterized, by a fixed-length packet format defining an address field and a data field, the original data packet carrying original data packet routing information in the address field and original data packet information in the data field; constructing a remnant packet characterized by the same fixed-length by the packet format as that of the original data packet, including a remnant packet data field and a remnant packet address field by inserting at least a original packet routing information in the remnant packet data field; constructing a subsequence remnant packet characterized by the fixed-fixed packet format by inserting a second portion of the original data packet information in the data field of the subsequent remnant packet; and sending the remnant packet through the intermediate communication network,
