摘要： To test a first device, the latter is connected to a simulator which simulates at least one second device according to a test case stored in a second data set. The simulator sends messages to the first device according to the test case, receives reply messages from the first device, and stores these reply messages in the second data set. According to the invention, the test is stored in advance as an abstract test scenario in a first data set. To generate the test case, the first data set is then mapped to the second data set by means of message-structure data and by insertion of basic-setting data. For evaluation, the second data set is mapped back to the first data set by data reduction.

The invention is a combination of a source of control vectors, which sends control vectors to a Programmable Performance Vector Generator which is coupled to a data communications network to be monitored and controlled. The control vectors configure an Event Driven Interface contained in the Programmable Performance Vector Generator, based upon the protocol of the network, performance information required, and the type of analysis and network characteristics required from the system. Event vectors are then output to an expert system which analyzes them and provides monitoring information and control signals to the network. The invention enables real-time load distribution, load balancing, problem determination, routing and customer services.

摘要： A data network switch for switching data between a plurality of data links is disclosed and includes a programmable controller which adapts the data switching in accordance with the state of the switch and the state of the data links. The programmable controller has detection apparatus which detects a problem in the operation of the switch, a memory which stores information on possible problems, their causes, and possible solutions, and a controller. The controller determines from the information stored in the memory the possible causes of the problem according to the nature of the problem detected and determines from the possible causes a ranked series of possible solutions. In addition, the controller carries out the first of the possible solutions, checks the output of the detection apparatus after a predetermined period of time, and if the problem is still present, carries out the next of the possible solutions, and repeats the checking and carrying out of the next of possible solutions until the problem is no longer present or no further possible solutions remain.

摘要： An apparatus for memory management in network systems provides added margins of reliability for the receipt of vital maintenance operations protocol (MOP) and station management packets (SMP). In addition, additional overflow allocations of buffers are assigned for receipt of critical system packets which otherwise would typically be discarded in the event of a highly congested system. Thus, if a MOP or a SMP packet is received from the network when the allocated space for storing these types of packets in full, the packets are stored in the overflow allocations, and thus the critical packets are not lost.

摘要： A multiple port network device, connected to a network, detects and records over which port of the multiple port network device other network devices communicate with the multiple port network device. A table is maintained in a memory. The table has entries which identify by which port of the multiple port network device other network devices communicate with the multiple port network device. The table is updated by monitoring packets received by the multiple port network device. When a packet is received by the multiple port network device, a port number over which port the multiple port network device received the packet is determined. Also, a source address of a network device from which the packet originated is determined. When the source address is not listed in the table, the table is updated with an entry for the source address which includes the port number.

摘要： A method and apparatus for remote maintenance and error recovery for plural stations interconnected in a distributed network. A monitor application is established within selected stations within the network in a terminate and stay resident mode. The monitor application is then automatically invoked in response to error message, reconfiguration messages, or network status messages received at that station by listing the monitor application address within user appendages associated with such error messages or reconfiguration messages within the network interface of the station. An error message may be displayed and any selected application or procedure may then be invoked by the monitor application in an application independent manner. In one embodiment of the present invention, a station may be reset remotely in response to an error message or reconfiguration message by utilizing the monitor application and the station may then be directed to establish communication with a server device in order to update system software. This may be simply accomplished within a computer station utilizing a DOS operating system by merely altering the automatic execution batch file.

摘要： A method and apparatus for inserting a computer network protocol analyzer into a Token Ring network. Commercial integrated circuits are used to initiate a standard protocol test and synchronization sequence and to actuate an insertion relay in a network coupling unit. After actuation of the insertion relay, incoming network data is switched onto outgoing network data lines, bypassing the commercial protocol circuitry. As a result, the analyzer can be inserted into a Token Ring even when there are network problems which would prohibit insertion under normal protocol.
摘要翻译：一种用于将计算机网络协议分析器插入令牌环网络的方法和装置。商业集成电路用于启动标准协议测试和同步序列，并在网络耦合单元中启动插入继电器。在插入继电器的启动之后，输入的网络数据被切换到输出的网络数据线上，绕过商业协议电路。因此，即使出现网络问题，即使在正常协议下禁止插入，也可以将分析仪插入到令牌环中。

摘要： A system for monitoring an ATM cross-connecting apparatus by rewriting a VPI conversion table to various values, inputting a test cell, and examining the test cell after the test cell passes through the ATM cross-connecting apparatus. Entries of a VPI conversion table are accompanied by traffic flags indicating whether or not the corresponding entry is occupied for use for user's signals. First, the traffic flags are examined. Each entry not occupied for user's signals can be freely rewritten. Each entry occupied for user's signals is not rewritten. The examination of the test cell is carried out by comparing the test cell output from the ATM cross-connecting apparatus, with a reference cell which is expected from a normal operation of the ATM cross-connecting apparatus. The virtual path identifier converted in the ATM cross-connecting apparatus and contained in the output test cell, is expected corresponding to the above rewriting operations, and is contained in the reference cell.
