ABSTRACT:
A nested frame communication protocol for communicating between computers. According to the nested frame communication protocol of the present invention, the computers communicate by transferring frames over communication links. The transmission of low priority frames may be interrupted in order to transmit high priority frames. After the transmission of the high priority frames is complete, the transmission of the low priority frames resumes. Processing states relating to interrupted frame transmissions are saved when the frame transmissions are interrupted. The processing states are restored when the interrupted frame transmissions are resumed.
