Embodiment Construction
[0028] At present, the network interface provided by the Leased Line transmission system (including SDH, PDH, ATM) in the public network is usually E1 / T1, and the bandwidth is 2Mbps or 1.5Mbps. The present invention is a scheme that can provide data with a bandwidth greater than 2Mbps (1.5Mbps for T1) and less than 8Mbps (6Mbps for 4 T1s), and use multiple E1 / T1 interfaces to transmit in the transmission network.
[0029] The present invention splits the service data stream to be transmitted into multiple N-byte data segments at the sending end, and adds header information in front of it to form a data segment including header information (hereinafter referred to as reverse Multiplexing frame), the inverse multiplexing frame is sent to the receiving end through one of the multiple E1 / T1 interfaces through a scheduling algorithm; the header information includes the sequence number of each data segment. At the receiving end, the inverse multiplexing frames received from each E1 / ...
