It is doubled and redoubled with the bandwidth of transmission net, optical transfer network（Optical Transport Network, OTN）Technology Optical signal is transmitted for transmission net by big pipeline to provide in more flexible scheduling mode, OTN because the light for needing to transmit is believed Number polytype operation level, therefore the multiplexing relation between optical signal is a variety of there is also having, this inevitably results in resource management Complexity with path computing is higher.
In optical signal mapping structure in OTN, the optical signal of low order grade can be from low layer light data unit （Optical Data Unit, ODU）Middle output, the optical signal of multiple low order grades can be multiplexed into high-rise light data unit, So as to export the optical signal of high-order grade, the optical signal of high-order grade can be sent to light wave long-channel（Optical Channel, OCh）On.
The multiplexing of optical signal can have various ways in the prior art, with one layer of light data unit（Optical Data Unit1, ODU1）Exemplified by the multiplexing of optical signal, for example, two kinds of multiplexer modes are there may be, one kind is to answer optical signal from ODU1 Use two layers of light data unit（Optical Data Unit2, ODU2）, then optical signal be multiplexed into three layers of light number from ODU2 again According to unit（Optical Data Unit3, ODU3）, another is that from ODU1 optical signal is directly multiplexed into ODU3.
In the ideal case, the optical signal business of a low order is all by the cross scheduling consistent with business rank itself To complete, but based on the reason for the efficiency of management, there are still largely use high order cross in the operation maintenance of real network Bridge the situation of low order signal, for example, the optical signal of lowest-order grade from ODU0 be multiplexed ODU2 when, may not have in existing network Have a cross scheduling consistent with the lowest-order rating, thus can only by the way of higher order signal intersects bridge joint low order signal come Realize the transmission of optical signal.
, can profit for the optical signal of low order grade but the present inventor has found during the present invention is realized Intersect the mode of bridge joint low order signal with higher order signal, whether there are still idle low order depending in intersecting in higher order signal Passage, therefore still there is very big uncertainty, if higher order signal can not be used to intersect the mode of bridge joint low order signal, need The cross scheduling consistent with the grade of service of the optical signal of low order grade is re-established, therefore bandwidth resources can be caused using effect Rate is relatively low.
