摘要： A communication data processor. Data received from a communication channel is stored in a data area. A list area corresponding to the data area in which the communication data has been stored is deleted from a vacant list management area and then added to a logical check list management area. A list area corresponding to a data area logically checked by a lower layer logical check section is deleted from the logical check list management area and then added to a higher layer protocol classification list management area. A list area corresponding to a data area classified by a higher layer protocol classification section is deleted from the higher layer protocol classification list management area and then added to the vacant list management area. When data relating to a protocol having an OSI model is to be processed, it is not required to perform the transfer of real data in a data storage.

摘要： A communication control section is provided with a plurality of receiving channels (RXDA1 and RXDA2). An address separated by an address separating section constituting the RXDA1 is compared with a reference address denoting a token, and if the separated address corresponds thereto, an interruption is requested by an interruption processing section. An address separated by an address separating section constituting the RXDA2 is compared with a reference address denoting the station number of that particular station, and if the separated address corresponds thereto, the interruption is similarly requested. When the interruption has been requested, the processing of a CPU transfers from the processing of a main routine by a main routine processing section to an interruption processing by an interruption processing section.

摘要： A communication network is comprised of several stations that constitute a logical ring to transmit and receive information. The logical ring is established and maintained by a token passing process and a solicit process. The token represents the right to transmit information between the stations in the logical ring. The solicit process solicits stations that are not in the logical ring. The stations in the network include at least one particular station. Each of the stations as well as the particular station include soliciting capability for carrying out the solicit process when holding a token. In addition, each station except for the particular station also includes first solicit repeat capability for repeating the solicit process at most a predetermined number of times when no frame arrives from other stations in the network, and the function of moving to an idle state when no frames arrives from other stations after the solicit process is repeated. The particular station further includes second solicit repeat capability for repeating the solicit process when no frame arrives from any station in the network in response to the solicit process executed by the particular station, and token producing capability for producing the token when no other station joins in the logical ring.
