An asynchronous transfer mode (ATM) network and method for operating an ATM network which provides for virtual channel merging of individual user data cells. The ATM network comprises a multiplicity of source stations, wherein each one of the source stations is identified by a source identifier (SID) and is connected to at least one non-merged virtual channel (VC); a first ATM switch having a first input, a second input, and an output, such that the first input is connected to one of the non-merged virtual channels (VCs), the second input is connected to a different one of the non-merged VCs, and the output is connected to a merged VC; and at least one destination station is connected to the merged VC, which maintains a SID allocation table containing each one of the source identifiers (SIDs).

In accordance with embodiments of the present disclosure, a method for identifying a target signal in an optical transport network frame structure may be provided. The method may include determining an Access Identifier (AID) for the target signal. The method may also include determining at least one attribute for the target signal. The at least one attribute may define at least one of an Optical Transport Network (OTN) multiplexing structure associated with the target signal and one or more attributes associated with one or a higher order or an intermediate higher order optical data unit entity for a supporting entity of a lower order optical data unit associated with the target signal. The method may further include identifying the target signal based on the AID and the at least one attribute.

Software inverse multiplexing within an Asynchronous Transfer Mode (ATM) communication network is provided by a first ATM switch receiving a stream of ATM cells over a high bandwidth communication link. A Segmentation and Re-assembly (SAR) module associated with the first ATM switch thereafter reassembles the received ATM cells into corresponding user packets. Control data identifying the sequence of assembled user packets are added to each user packet and de-assembled into corresponding ATM cells. The de-assembled ATM cells are then communicated over a plurality of low bandwidth communication links to a second ATM switch. The second ATM switch receives the transmitted ATM cells over said low bandwidth communications links. A SAR module associated with the second ATM switch thereafter reassembles the received ATM cells into corresponding user packets. Utilizing the enclosed control data, received user packets are re-synchronized into their original sequence.

Methods and systems for optical data unit (ODU) path protection in a disaggregated optical transport network (OTN) switching system that include using plug-in universal (PIU) modules each having multiple ports for OTN to Ethernet transceiving and an Ethernet fabric as a switching core are disclosed. An OTN over Ethernet module in each of the PIU modules may enable various OTN functionality to be realized using the Ethernet fabric which may include multiple Ethernet switches. An egress PIU module may receive Ethernet packets via the Ethernet fabric from a working ODU path. In response to determining that a protection switch using a protection ODU path may be performed on the working ODU path, the egress PIU module may receive the Ethernet packets via the Ethernet fabric from the protection ODU path.
