摘要： Monitoring is done of communications which occur in a network of nodes, each communication being effected by a transmission of one or more packets among two or more communicating nodes, each communication complying with a predefined communication protocol selected from among protocols available in the network. The contents of packets are detected passively and in real time, communication information associated with multiple protocols is derived from the packet contents.

摘要： A method of displaying information relating to performance of a computer resource over a preselected period of time, wherein the computer resource is connected to a communication network and the method includes the steps of: from a location on the network that is remote from the computer resource, periodically sampling data relating to performance of the resource so as to generate stored values for a preselected performance variable for that resource, wherein the periodic sampling takes place over a preselected period of time and the preselected performance variable takes on values within a specified range of possible values; dividing the specified range of possible values for the preselected performance variable into a plurality of subranges; for each subrange, determining for what proportion of the preselected period, the values of the preselected performance variable fall within that subrange; and for each subrange, displaying in graphical form the proportion of the preselected period of time that the values of the preselected performance variable fell within that subrange.

摘要： The invention features methods of, and systems for generating a report that depends on data stored in a plurality of remote workstations. The methods and systems involve at least some of the following steps: sending a request from a master workstation to the remote workstations specifying a group name and a named function; identifying data stored within each of the remote workstations belonging to a group specified by the group name; operating on the identified data within each of the remote workstations according to an algorithm specified by the named function to generate an output for each remote workstation; returning the output from each remote workstation to the master workstation; and consolidating the outputs at the master workstations to generate the report.

摘要： An access controller for peer-to-peer communication networks which monitors the data packets transmitted between stations, determines when an access that needs to be controlled is being made, and then either destroys the packet or transmits one or more packets which appear as legitimate message packets to the stations but which, in fact, terminates or alters the communication path between the two stations. Since the invention is free of any particular protocol restrictions, it can be implemented with any type of protocol and at any layer of that protocol. And since the access control mechanism is neither part of the physical communication path nor part of the communication primitives, the stations cannot detect, in any direct sense, that their access is being controlled, and they do not need to be programmed to follow any special control protocols, or to use encryption. A signature signal can be used as a safety mechanism to prevent multiple access controllers from controlling the same network, to prevent an unauthorized access controller from seizing control of the network.
摘要翻译：用于对等通信网络的接入控制器，用于监视站间传输的数据分组，确定何时正在进行需要控制的接入，然后破坏数据包或发送一个或多个显示为合法消息的数据包分组到站，但实际上终止或改变两个站之间的通信路径。由于本发明没有任何特定的协议限制，所以它可以用任何类型的协议和协议的任何层来实现。并且由于访问控制机制既不是物理通信路径的一部分也不是通信原语的一部分，所以站不能在任何直接的意义上检测到它们的访问被控制，并且它们不需要被编程以遵循任何特殊的控制协议，或使用加密。可以使用签名信号作为安全机制来防止多个接入控制器控制相同的网络，以防止未经授权的访问控制器占用网络的控制。
