Improved techniques for reporting events raised by entities running on computer networks are disclosed. The techniques provide an event distribution system that handles events generated by various software and other entities installed on a computer or communications network. The event distribution system is capable of handling large volumes of event traffic and can be installed and operated separately from other network management software components to provide thereby more robust operations in the case one or more components fail. In addition, the event distribution system can be scaled readily to handle greater volumes of network traffic. In one embodiment, an event distribution service is coupled with an event source. In addition, an event listener is provided on the computer network. When an event is generated from the event source and received by the event distribution system, the event distribution system processes and forwards the event, or a notification of the event, to an appropriate listener.
A project data management system and method are provided wherein any user associated with a project may access any of the information relevant to the project regardless of the location of each user or the information and regardless of what tool was used to create the information. The system also permits user to interrelate information items from different locations or different tools. In a preferred embodiment, each user may use a typical web browser application to access the information. The system may check and maintain the integrity of the information and/or alert each user when there is an inconsistency in any of the information associated with the project. The system makes the access, integration and monitoring of information between a distributed project team manageable and reduces the manual effort and time spent accessing information, determining the relationship between different items of information, and avoiding inconsistencies between different pieces of information.
A system and method for authenticating a legacy service using internet technology is disclosed. An authentication module is associated with the legacy server. Service requests from a user of the legacy server are passed to the authentication module. The authentication module generates a service request for a web server, requesting access to a protected page from the web server, and transmits the user's credentials to the web server. The web server attempts to access the protected server, which causes the web server to access a network-based authentication service to determine whether the user's credentials qualify for access to the protected page. The web server transmits a message back to the authentication module, which determines whether the user's credentials qualify for access the legacy server based on the message from the web server.
A method and system for providing system event notifications to clients such as applications. Clients register for notification of one or more types of events with a registration mechanism, and a System Event Notification Service, (SENS), receives system event information and fires event notifications in response thereto. A distribution mechanism selectively communicates the fired event to each client registered for notification thereof based on the type of event. Events include network events, for which the service monitors the connectivity state of the machine, including whether a connection is established or lost, the type of connection (LAN/WAN) and bandwidth information. To monitor a LAN state, the service caches outgoing and incoming network information including errors and packet counts and statistically evaluates this cached information against current information to determine whether the connection is established or lost. The service also determines if a destination (IP address or name) is reachable, by periodically polling destinations. Other system event notifications may be fired, including logon or logoff operations and power management events.
A device, such as an Application Specific Integrated Circuit (ASIC) which has access to a memory, such as non-volatile RAM (NVRAM) or Electrically Erasable Programmable Read Only Memory (E.sup.2 PROM). The device may reside in a PC or on a network interface card for providing an interface between the PC and a network, such as an Ethernet-based network. Software on the PC constructs a base packet or template for an SNMP trap PDU and stores the template into the NVRAM or E.sup.2 PROM associated with the device. When the device determines the need to generate and send the SNMP trap PDU, the device can, without a CPU and without a full implementation of network layer software stacks, generate the SNMP trap PDU based on the base packet stored in the NVRAM. The device need only insert the non-static data into the packet built from the base packet before sending the packet to a communication controller, such as an Ethernet controller, which subsequently sends the packet over a network, such as the Ethernet-based network.
A method for determining, storing, and managing names for agents and entities installed on a computer network is described. In one embodiment, a method is provided for providing a name service configured to provide unique identifiers and addresses for processes on a computer network. The name service includes a database of identifiers and addresses for the processes. A query is made to the name service that searches the database and the name service returns the answer.
