Abstract: A method, system, and computer program product for enabling messaging system s to use alternative message delivery mechanisms. In existing instant messaging systems, messages cannot be delivered to an intended recipient unless the recipient is currently logg ed on to an instant messaging system. According to the present invention, users may register one or more alternative message delivery mechanisms (such as pagers, cell phones, etc.) through whic h they are available as an alternative to an instant messaging system. Constraints may optionally be added to these registered alternatives, such as specifying a limitation on days of the week and/or hours of the day when a particular alternative may be used. Providing that an alternative messaging mechanism is registered, and any constraints for this alternative are satisfied, in the first preferred embodiment the extended IMS will select a suitable alternative and deliver the message. In a second and third preferred embodiment, the sender of the "instant" message will be informed o f the available alternative(s). The sender may then choose to have his message delivered eve n though the intended receiver is not currently logged on to an instant messaging system. Fourth a nd fifth embodiments enable a message to be delivered to a recipient using a registered mechanism (that may include an IMS), and provide for determining availability of a selected user. Using the se techniques, the real-time awareness of potential message receivers in instant messaging systems is extended.

Abstract: Method of disseminating information in a computer network wherein, upon activating any link in the network, a first exchange of signals between nodes attached to said link is automatically initiated for providing each of the attached nodes with information indicating the availability of the node at the other end of the link for participating in a predetermined type session. If both nodes are available for participating in a the session, a second exchange of signals between the nodes is initiated for establishing a session. Then a third exchange is automatically initiated for providing the nodes with information needed to make effective use of the session. Upon completion of said third exchange, internal operations are conducted at said nodes designating the session as a predetermined type session and making said session available to transaction programs at the nodes for exchanging additional network state information as needed.

Abstract: A search dynamically locates resources (e.g., logical units (LUs) and transaction programs and files associated with LUs) in a computer network so that a session can be established between the origin and the destination of the search. The network includes end nodes associated with server nodes,and a resource contained in any node is located by a requesting node. The requesting node initiates a search of the resources residing within itself. If the resource does not reside in the requesting node, the server node searches the resources known to the server node that reside anywhere in the network. If the resource is not known by the server node, it searches all resources that reside in its associated end nodes. If the resource does not reside in the associated end nodes, either a request is sent to a central directory if one exists or a search of all resources in the network is made.
