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. Enabling signals produced by the Event Driven Interface are applied to the control input of a multiplexer whose data input is connected to 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 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： 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 is disclosed for the dynamic switching between a first Event Driven Interface and a second Event Driven Interface based upon inband information contained in the data frames of a data communications network. This enables the selective realtime transfer of routing control based upon diverse communications protocols, for example. A first routing table can be contained in a first Event Driven Interface and a second routing table can be embodied in a second Event Driven Interface, and in this example, by means of the first Event Driven Interface identifying the switchover pattern contained within a switching segment of the data frame, the system can automatically switch over to connect a second Event Driven Interface to the data communications network, containing a second routing table configuration. In this manner, realtime control of routing, for example, can be accomplished with inband information in a data communications network.

摘要： A realtime high speed data capture is provided in response to a trigger bit pattern detected in a serial bit stream. An Event Driven Interface is connected to a data communications network to receive a serial bit stream. A capture buffer is connected to the network to store at least a portion of the serial bit stream. The capture buffer is selectively connected to the network by means of a gate. The Event Driven Interface is programmed to recognize a trigger bit pattern in the serial bit stream and to output an enable signal to the gate. In response to this, the capture buffer will store a predetermined portion of the serial bit stream from the network.

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.
