Title: Frame removal mechanism for token ring network
Inventor: YANG HENRY S
IPC: H04L12/433
Filed: 1991-06-28
Abstract: IMPROVED FRAME REMOVAL MECHANISM FOR TOKEN RING NETWORK     ABSTRACT OF THE DISCLOSURE          Frame processing apparatus,  and a related method for its operation, for use in a station connect-ed to a token ring network, to ensure rapid stripping of frames from the network without reference to source addresses in the frames, and in spite of the possible presence of extraneous no-owner frames on the network. The adverse effects of extraneous no-owner frames are avoided by any of three techniques. First, transmitted information frames are preceded by a start strip delimi-ter frame and followed by an end strip delimiter frame. The process strips all incoming frames (except tokens and ring initialization frames, which are specially handled), but does not count the stripped frames until the start strip delimiter frame  is detected. Therefore, extraneous frames preceding the transmitted information frames will be stripped but not counted, and all of the transmitted frames will be stripped.  In another ap-proach, an estimated stripping time is used to termi-nate stripping. Frame counters are not then needed and extraneous frames will be stripped prior to the desired information frames. A third approach is to preset the transmitted frame count to some selected value, so that more frames will be stripped than were transmitted. Thus, preceding extraneous frames will be stripped, but the end strip delimiter will still terminate stripping and preclude overstripping.

Abstract: SCIENTIFIC VISUALIZATION SYSTEM     ABSTRACT OF  HE DISCLOSURE            A  multiprocessor  data  processing  system  (10),  and  a method of operating  same,  so  as to provide efficient bandwidth utilization of  shared  system  resources  (24, 26). The system includes a plurality of processor nodes, each of which includes a data processor (22a,  28a).  In accordance with a method of the invention a first step buffers data written by a data processor to a first bus (23a), prior to the data being transmitted to a second bus  (32).  A second step also buffers byte enable  (BE) signals generated by the data processor in conjunction with the data written by the data processor. A third step performs a main memory (26) write operation by the steps of:  transmitting the buffered data to the second bus; responsive to the stored BE signals, also transmitting a control signal for indicating if a memory write is to be accomplished as a read-modify-write (RMW) type of memory operation; and transmitting the stored BE signals to the second bus.  A further step couples the data,  the RMW signal, and the BE signals from the local bus to a third bus  (24)  for reception by the main memory.  Interface circuitry  (34)  associated  with  the  main  memory  is responsive to the RMW signal for (a) reading data from a specified   location   within   the   main   memory,   (b) selectively merging the transmitted data in accordance with the BE signals, and (c) storing the previously read and merged data back into the specified location.
