摘要： A communication control equipment connected between a computer and a network so as to perform protocol processing at a high speed, has a buffer memory connected between a computer interface circuit and a network interface circuit through a first path for data transfer, so as to temporarily store communication data, and a protocol processor connected between the computer interface circuit and the network interface circuit through a second path for control information transfer. The protocol processor is also connected to the buffer memory through a third path so as to effect protocol processing on the communication data within the buffer memory. The protocol processor includes a plurality of processor units connected in series in the second path so as to respond to control information received from the second path to make access to the buffer memory through the third path and to execute a first category of protocol processing necessary in normal data transfer on the communication data stored in the buffer memory. If protocol processing other than the first category of protocol processing on the communication data is necessary, the processor units supply the control information to the third path. The protocol processing also includes a second processor which operates as a backend processor for the processor units and which is connected to the third path so as to respond to the control information received from the third path to execute protocol processing other than the first category of protocol processing on the communication data stored in the buffer memory.

摘要： A protocol high-speed processing method to be used in a first communication control equipment for communications with a second communication equipment connected through a transmission line in accordance with a predetermined communication protocol. The communication control equipment predicts the type of communication frame to be received next from the communication line, in accordance with type of communication frame previously transmitted to or received from said transmission line, and prepares information necessary for a process of receiving said predicted communication frame and information of a part of the communication frame to be transmitted subsequent to the receiving process, to await the reception of a next communication frame. As a result, the receiving process time and the response process time can be reduced when the actually received communication frame is consistent with the predicted one.

摘要： A mobile communication system with a packet switching function which enables sharing of radio resources among mobile stations, wherein a mobile station which has generated a request for communication quality assurance periodically sends a packet for requesting preferential use of a radio channel in order to prevent timeout of the state transition timer, timeout of which would cancel radio channel assignment to the mobile station and bring it into a dormant state if a certain period elapses without transmission or reception of a signal, so that it can remain in the active state and hold the radio channel continuously. In addition, when the mobile station requesting communication quality assurance moves from one cell to another or requests radio channel assignment, the base station controller controls the radio base station so that the mobile station can be assigned a radio channel by sending a priority request packet.

摘要： There is provided an address translator having the functions to prevent, in the communications via the address translation, transmission of packets having no correct destination and transmission source addresses which will cause troubles in the networks and to urge an administrator take adequate measures for reception of the relevant packets. This address translator stores discriminator to discriminate temporary addresses. Moreover, when the original address is registered as the temporary address at the time of assignment of the temporary address of the receiving side host started when the name solution is performed, assignment is rejected to prevent transmission of packet from the transmitting side host by returning a response for name solution error to the transmitting side host. In addition, when transmission source address before translation and destination address after translation are registered as the temporary address, the received packet is discarded. Moreover, assignment of the temporary address is rejected and the packet is discarded, a message is transmitted to an alarm device or external host to notifying the event to an administrator.
