    Abstract: A method is disclosed for allowing two nodes (12, 14) in a communications network to dynamically establish the transmission group number used to partially identify a given link (18) between the nodes. When the link is being activated, both nodes simultanesouly propose either a zero or a non-zero number to each other in an exchange of exchange identification (XID) messages. If only one of the nodes proposed a non-zero number, that non-zero number is selected as the transmission group number. If both nodes had proposed zero or both had proposed non-zero numbers, predetermined criteria are employed to select a controlling node. The controlling node chooses the final transmission group number and communicates that choice to the non-controlling node.

    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.
