Method and apparatus for transmitting and receiving multi-protocol data frames

摘要

The present invention relates to method and device for transmitting and receiving multi-protocol data frames. The method of the present invention includes receiving data from frame convergence sub layers (FCSLs) supporting a variety of different protocols, transmitting the data including identifiers for identifying which FCSL sends the data, and locating a relevant FCSL based on the identifier included in the data forwarded by other devices and delivering the received data to the relevant FCSL. The device of the present invention includes at least two FCSLs, an FCSL LLC (logic link control) (400) for adding identification information to allow a receiving device to identify from which FCSL the data are received, and a MAC (medium access control) layer (100) for transmitting and receiving the data.
