摘要： The disclosed system allows determination of topological aspects of a high speed data communications network in real time without interfering with the operation of the network. The topographical information determined by the present invention includes the cable length of the network, the cable length between stations on the network, and the station addresses and relative order of stations on the network. The system determines the cable length of the network by dividing the amount of time that a token spends on the cables of the network as it travels completely around the network by the propagation speed per unit length of the cables of the network. The system determines the length of cable between any two adjacent stations on the network by determining the length of time between frames transmitted by the adjacent stations, and dividing this time by the propagation speed per unit length of the cable of the network. Lastly, the system determines the number of stations and the addresses of these stations on the network by extracting source addresses from the pertinent network frames.

摘要： The present invention discloses a system for processing data from scanned documents. The output from a scanner serves as input to a digital filter referred to as an event driven interface. The event driven interface is user-configured with bit patterns to identify and filter out user-designated information from a scanned document. Since only the designated information is extracted from the document, and not extraneous matter of the document, the subsequent storage of only the designated information saves computer memory. Furthermore, the designated information can be transmitted over a data communications network. Such a transmission will occupy less bandwidth than if the entire document was transmitted.

摘要： The invention includes indirect addressing which is the realtime calculation of the location of variably offset fields in a frame in a high speed medium. Data frames in a communication medium, include a presence bit which indicates the presence of a variable length field whose length is defined by a length field in the data frame. In accordance with the invention, an Event Driven Interface has its input coupled to the data communications network, to receive the data frame and to identify the presence of the presence bit. In response to this, the Event Driven Interface branches to a first logic path which ignores the plurality of bits in the variable length field corresponding to the length field. Then, the Event Driven Interface branches to a second logic path after the plurality of bits have been ignored, to locate the variably offset field being sought in the data frame. This enables the realtime location of data at variable offsets in the data frame.

摘要： The realtime event classification technique is described for a data communications network, which enables the categorization of data frames based upon selection significant bit segments in the serial bit stream. A base Event Driven Interface and an extension Event Driven Interface are both coupled to the data communications network, to identify patterns in the serial bit stream. The base Event Driven Interface identifies patterns which correspond to events which are to be counted. The extension Event Driven Interface identifies patterns of bits which are selection significant for the types of categories which are desired to be monitored. A plurality of event vector counters have event inputs coupled to the base Event Driven Interface and have a selection input coupled to the extension Event Driven Interface. A selection signal output from the extension Event Driven Interface enables one of the plurality of the event vector counters to receive the event signals from the base Event Driven Interface. In this manner, a variety of monitoring and analysis operations can be performed on the data communications network.

摘要： A dynamic realtime, inband routing mechanism is disclosed for a data communications network, which provides an Event Driven Interface to perform realtime, inband directed routing for load distribution and load balancing of data frames over one of a plurality of destination paths. The Event Driven Interface is programmed with control vectors to identify load balancing and load distribution bit patterns in the data frames on the data communications network.

The multiplexer will steer the data frames from the data communications network to one of a plurality of output alternative routing paths, in response to the enabling signals it receives from the Event Driven Interface.

摘要： The invention features a system and method to enable real-time establishment and maintenance of a standard of operation for a data communications network. The standard is a data set which includes network activity which is historically categorized by traffic type and by activity. The process begins with monitoring the network media or some network component over some period of time. The monitoring information is used to build benchmark data sets. The benchmark data sets contain a standard of operation for the network, which are historically categorized by either traffic type or activity. This standard of operation is constantly built by the intelligent monitoring facilities. After some period of time which is referred to as the benchmark data set refresh interval, the benchmark that was created is employed in a fashion to allow a determination as to whether the data that is taken from the current monitoring activity indicates normal network behavior. If the current network operating characteristics are outside the bounds or normal behavior, then alerts and logs of information can be sent to the expert system. The expert system can then effect some network control. In this manner, auto benchmarking is accomplished with self customization.

摘要： A high speed data communication network is adapted to monitor and measure response time between a work station and a central host or processor coupled to the data communications network through a media, such as token ring, FDDI, Ethernet, etc. As the workstation communicates with the processor, a flag is set in a packet transmitted to the processor. The packet traverses the network to an application in the processor and a response returns which includes a flag. Each flag is a specific bit pattern. A programmable digital filter recognizes the flags and counts the number of bits on the network between the flags in the forward and reverse direction. By counting the bits on the media, when the flag moves in one direction or another, the total number of bits transmitted on the media between the two intervening flags is determined. The media speed is used as a clock. The number of bits counted divided by the media speed determines the response time with fine resolutions. All of the measurements are done in near real time without the use of clocks or off-line processing of data to determine response time. The measurements can be done for half duplex or full duplex operation of a network. The measurements can be also used in the network to initiate performance changes according to the response time.

摘要： A system and method for passively measuring and correcting ring latency on a token or FDDI ring includes generating bits and token frames in a defined pattern according to the token ring protocol. A passive device coupled to the token ring measures CMIN, the minimum spacing, CMAX, the maximum spacing in bits and calculates Fi the frequency of changes in Cmin and Cmax between successive tokens or a token and a frame on the ring. A latency event vector Li is generated by the passive device. A controller responsive to the latency vector Li corrects the spacing between successive tokens or a token and frame to achieve a constant ring latency regardless of electrical or operational changes on the token ring.
