Abstract:
1. A transmission apparatus for a dynamic lane operation in a multi-lane based Ethernet system, comprising: a monitor to monitor whether at least one lane being used by the transmission apparatus is modified; an upper layer manager to transmit, to a Reconciliation Sublayer (RS) of the transmission apparatus, lane change information associated with the modified at least one lane; an RS manager to transmit the lane change information to an RS of a reception apparatus corresponding to the RS of the transmission apparatus; and a Physical Coding Sublayer (PCS) manager to change a number of at least one lane being used by the reception apparatus based on the lane change information; wherein the PCS manager receives a number of alignment markers and a number of synchronization bits corresponding to the changed number of at least one lane with respect to each of the at least one lane being used by the reception apparatus, and subsequently allocates the at least one lane being used by the reception apparatus based on the changed number of at least one lane; the PCS manager comprising a lane block synchronization module to receive, from a lower layer, a synchronization signal and a control signal for each of the at least one lane being used by the reception apparatus, and an alignment lock lane disqueue module to adjust, using the control signal, an alignment state and a torsion of each of the at least one lane being used by the reception apparatus, wherein the lane block synchronization module or the alignment lock lane disqueue module operates depending on whether a number of synchronization bits and a number of alignment markers received with respect to the at least one lane being used by the reception apparatus match a number of lanes being currently used.
