A method and system for interconnecting multiple distributed components in a communication network is provided. The design includes a multiple order cross connection fabric employed to interconnect multiple orders of data with at least one distributed component in the communication network. The design may further include at least one order of path termination and adaptation connection, where the at least one order of path termination and adaptation connection providing an interface between the multiple order cross connection fabric and a data management system. The design may be implemented in a SONET/SDH environment.

A data transmission method and apparatus, a network device, and a storage medium are provided. In the method, a first network device determines whether there is a packet to be sent at a switching moment of a current time window; and the first network device sends a preset identification packet to a second network device in a case where there is no packet to be sent at the switching moment of the current time window, wherein the preset identification packet carries a window value of the current time window, and the window value is used for enabling the second network device to determine switching moments of different time windows of the first network device.

Provided are a method for determining and sending a multiframe, and a communication device. The method includes: for physical layers of different interface bandwidth speeds, determining a multiframe number of the multiframe to be n-th power of 2, where n is a minimum positive integer that causes the multiframe number greater than or equal to a number of timeslots of a physical layer, identifier values of the multiframe identifier for identifying the multiframe number are sequentially carried in preset positions of overhead blocks of respective frames constituting the multiframe, and the number of the identifier values of the multiframe identifier is the same as the multiframe number. The identifier values of the multiframe identifier are a preset number of consecutive 0s and the preset number of consecutive 1s in sequence.

In one example embodiment, data is received at a node of a network. The data includes encrypted data segments containing data portions and error correction information. The encrypted data segments are decrypted to produce the data portions and the error correction information. Error correction is performed on the data portions using the error correction information. Corrupt data is determined based on the error correction indicating uncorrectable data.
