Embodiment Construction

[0030] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0031] As mentioned above, the network interface provided by the Leased Line transmission system (including SDH, PDH, ATM) in the public network is usually E1 / T1 (the electrical characteristic definition of a transmission interface, see the standard ITU-T G .703), the bandwidth is 2Mbps or 1.5Mbps, using multiple E1 / T1 interfaces for transmission in the transmission network, providing data transmission with a bandwidth greater than 2Mbps (1.5Mbps for T1) and less than 16Mbps (12Mbps for T1) method. That is, when the channel bandwidth between two communication terminals is greater than the bandwidth provided by the network interface, it is necessary to disperse (Devide) the transmitted high-bandwidth data to multiple network interfaces for transmission, and then collect the data of multiple network interfaces at the receiving e...

Abstract

This invention puts forward a backward multiplex method for multi-channel network interface including the following steps: 1) frame alignment process: sending backward multiplex frame to determine interface numbers according to the transferred data bandwidth and finish the frame alignment process of the sending and receiving interfaces to the related numbers 2) sequence determination of the network interfaces: determining the logic sequence of the said interfaces in backward multiplex according to their identification 3) determination of relative time delay: determining the relative time delay between network interfaces according to the identification and the frame numbers.

Description

Technical field: [0001] The invention relates to a method for inverse multiplexing of multiple network interfaces, in particular to a method for inverse multiplexing of multiple E1 / T1 interfaces. Background technique: [0002] At present, the network interface provided by the Leased Line transmission system (including SDH, PDH, ATM) in the public network is usually E1 / T1 (a definition of the electrical characteristics of a transmission interface, see standard ITU-T G.703), the bandwidth 2Mbps or 1.5Mbps, using multiple E1 / T1 interfaces for transmission in the transmission network, providing a data transmission method with a bandwidth greater than 2Mbps (1.5Mbps for T1) and less than 16Mbps (12Mbps for T1). The existing multi-channel E1 / T1 inverse multiplexing technology generally decomposes the code stream to be transmitted into data packet sequences of related application formats according to different applications, and adds a packet identification header to each data packe...
