Patent ID: 6963568

Claim:
A method for transmitting a data packet, characterised by the steps of: extracting from each of at least two first data packets ( 1 , 1 i , 1 j , 1 k ) an original first destination address ( 31 ) and a first body part ( 4 , 4 i , 4 j , 4 k ) containing data to be transmitted by the first data packet ( 1 , 1 i , 1 j , 1 k ), the extracting step including: determining a first header part ( 2 , 2 i , 2 j , 2 k ) of each first data packet ( 1 , 1 i , 1 j , 1 k ), said first header part ( 2 , 2 i , 2 j , 2 k ) containing data packet specific information including an original first destination address ( 31 ), determining from each of said first header parts ( 2 , 2 i , 2 j , 2 k ) the original first destination address ( 31 ) of the first data packet ( 1 , 1 i , 1 j , 1 k ), storing the original first destination address ( 31 ) of the corresponding first data packet ( 1 , 1 i , 1 j , 1 k ) in second storing means ( 572 ), discarding the first header parts ( 2 , 2 i , 2 j , 2 k ), storing in first storing means ( 571 ) a remaining part of each of the first data packets, as a first body part ( 4 , 4 i , 4 j , 4 k ), making a concatenated or second data packet ( 1 ′), the concatenated or second data packet ( 1 ′) including: a second header part ( 2 ′) containing second data packet specific information including a second destination address ( 31 ′) for the concatenated or second data packet, a second body part ( 4 ′, 41 - 47 ) including: a data part ( 45 - 47 ) including the first body parts ( 4 , 4 i , 4 j , 4 k ) of said first data packets ( 1 , 1 i , 1 j , 1 k ) and a content information part ( 41 - 44 ) including information determining the position of each of the first body parts ( 4 , 4 i , 4 j , 4 k ) in the data part, the number of first body parts ( 4 , 4 i , 4 j , 4 k ) contained in the concatenated or second data packet ( 1 ′) and said original first destination addresses ( 31 ) of the first body parts ( 4 , 4 i , 4 j , 4 k ), transmitting the concatenated or second data packet ( 1 ′) to said second destination address ( 31 ′).
