摘要： Methods and apparatus are set forth which enable a data communications network (1) to perform decentralised uplink network control functions (decentralised away from the centralised general communications controller (GCC) level of the network hierarchy); (2) to minimise, or in some cases eliminate, the overhead expended in making power lever (signal strength) determinations and assessments at both the GCC and base station levels of the network hierarchy (for the purpose of managing uplink communications); and (3) to allow individual subscriber radios (terminals) to dynamically determine the most desirable base station to communicate with when exchanging information a host computer via a shared RF communication channel (the link between a terminal and the base station). Additionally, an illustrative radio frequency data communication network, built in accordance with the teachings of the invention as a modified version of an existing network, is described where the modified network incorporates the aforementioned methods and apparatus.

摘要： IN-BAND/OUT-OF-BAND ALERT DELIVERY SYSTEM An in-band/out-of-band alert delivery system far a computer system manager includes an alert log which maintains a record of alerts to be delivered and the status of those alerts, an alert manager for making a first attempt to deliver each alert, and a retry manager for making subsequent attempts to deliver alerts as becomes necessary and appropriate. The alert delivery system may also include a bus master interface manager for making inband alert deliveries and a communications manager for making out-of-band alert deliveries. Telephone numbers are provided to the communications manager by an alert destination list. Outof-band alert deliveries may be made via a modem, a universal asynchronous receiver transmitter, or the like.

The system manager transparently monitors signals transferred between computer system components along a system bus and stores objects related to the monitored signals in an object space. Information related to operating conditions within the system can then be provided from the object space. Later, the object space can be updated and the updated object space used to provide updated information regarding the operating conditions of the system

摘要： METROPOLITAN AREA NETWORK ARRANGEMENT FOR SERVING VIRTUAL DATA NETWORKS A high capacity metropolitan area network (MAN) is described. Data traffic from users is connected to data concentrators at the edge of the network, and is transmitted over fiber optic data links to a hub where the data is switched. The hub includes a plurality of data switching modules, each having a control means, and each connected to a distributed control space division switch. Advantageously, the data switching modules, whose inputs are connected to the concentrators, perform all checking and routing functions, while the 1024x1024 maximum size space division switch, whose outputs are connected to the concentrators, provides a large fan-out distribution network for reaching many concentrators from each data switching module. Distributed control of the space division switch permits several million connection and disconnection actions to be performed each second, while the pipelined and parallel operation within the control means permits each of the 256 switching modules to process at least 50,000 transactions per second. The data switching modules chain groups of incoming packets destined for a common outlet of the space division switch so that only one connection in that switch is required for transmitting each group of chained packets from a data switching module to a concentrator. MAN provides security features including a port identification supplied by the data concentrators, and a check that each packet is from an authorized source user, transmitting on a port associated with that user, to an authorized destination user that is in the same group (virtual network) as the source user.

摘要： Data communications connections between interactive terminals and host computers generally exhibit long holding times, while the data density of the transmissions is sparse. The circuit switch of a switching system is an inefficient and expensive medium for this type of communication. Thus, the subject switching system uses a packet switch connected in parallel with the circuit switch to handle bursty data traffic from interactive terminals. A routing bit is set in the data stream from each port circuit to indicate the nature of the transmission and this transmission is then routed to the packet switch if it is a bursty data transmissions while voice messages are routed to the circuit switch.

摘要： A data processing system including a storage section, a processing section, a control section, and a memory. The control section performing an action to allocate, to all of the ports, a time slot of a period of time which guarantees one seek action within a cycle time period which is the shortest time period within which it is permitted for the ports to successively accept a readout instruction, allocate, when another readout instruction is received, two or more time slots to that one of the ports which is designated by the readout instruction within a first cycle time period, and allocate one time slot to the port designated by the readout instruction within a second cycle time period after the first cycle time period. The processing section being operable to read out data from the storage section within one cluster per one time slot through that one of the plural ports to which the time slot is allocated by the control section and write the read out data into the memory and then process or output the data read out from the memory.

摘要： A technique restores adjacencies between a non-stop forwarding (NSF) router and its neighboring routers during reload of routing protocol software on the NSF router within a computer network. When a new instance of the routing protocol software is re-loaded, each interface of the NSF router is placed in a special state that enables it to receive incoming Hello packets from its neighboring routers. When placed in the special state, the interface passively “listens” for incoming Hello packets from the neighbors to determine which neighbors send the packets. The router thereafter promptly creates and sends a unicast Hello packet to each neighbor from whom it has received an incoming Hello packet and creates associated neighbor data structures.

摘要： A method and apparatus are provided for connection-oriented switching in a communications network wherein a pre-established path is established between a select pair of an ingress switch and an egress switch. The use of pre-established paths enables a reduction in the total number of connections required inside the switch cloud, reduces the CPU load on trunk switches, and shortens the time for connection setup. In the embodiment described, the DA/SA fields of a MAC frame data packet are replaced with a "virtual path", which identifies the pre-established path between the ingress and egress switches. A "virtual circuit" is provided in another field of the modified packet which specifies the out-port and out-header on the egress switch for demultiplexing the modified packet upon receipt at the egress switch. The virtual circuit is exchanged between the ingress and egress switches at connection setup. The virtual path is assumed to already be in place, and known to both switches, prior to connection setup.
