Patent ID: 7239649

Claim:
A transmission system for controlling the transmission of a concatenation signal, the system comprising: a sending apparatus including: signal dividing means for dividing, according to a bit rate available for a transmission line, the concatenation signal to generate a plurality of divided signals which are concatenation signals having a SONET or SDH multiplexed interface, the bit rate of which is lower than that of the original concatenation signal; guarantee information adding means for adding guarantee information for guaranteeing the continuity of the divided signals to each of the divided signals to generate transmission signals; signal sending means for assigning the transmission signals to transmission lines to have capacity that is suitable for service contents and sending the transmission signals to one address, in parallel via a plurality of the transmission lines on which the bit rate is limited; a receiving apparatus including: signal receiving means for receiving the transmission signals; signal restoring means for restoring the original concatenation by constructing the divided signals on the basis of the guarantee information; and wherein the receiving apparatus further includes delay information notifying means for giving the sending apparatus delay information regarding delays which have occurred at the time of receiving the transmission signals; and wherein the signal sending means calculates the bit rates of the divided signals respectively on the basis of the delay information; and wherein the signal dividing means divides the concatenation signal to meet the conditions that X 1 + . . . +Xn=X, that all the divided signals should reach by time t 1 , and that X1≧X2≧ . . . ≧Xn where X is the bit rates of the concatenation signal and X 1 –Xn are the bit rates of the divided signals and t 1 is a receiving end time of a divided signal which arrived at the receiving apparatus fastest.
