1. A method for use in a Token ring network including a plurality of stations serially connected by a transmission medium so as to form a closed loop on which packets of data are circulated, wherein each respective station includes media access controller means for scheduling and routing data transmissions on the transmission medium, buffer memory means for storage of information, and processor means for controlling operation of the respective station, the processor means having access to the buffer memory means, the method comprising the steps of:

  • transferring data of a respective packet from a media access controller means of a respective station to the buffer memory means of the respective station;

    storing the data in a sequence of contiguous memory locations in the buffer memory means;

    in the course of said step of transferring the data, generating status information for the data; and

    after said step of storing the data, storing the status information in the buffer memory means contiguously with the stored data at the beginning of the sequence of memory locations in which the data are stored.
