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.

Abstract: A facility called "Gateway" is used to interconnect a plurality of independently controlled communication networks so that logical units (LUs) in the networks can communicate with one another without any changes to the network. The gateway includes a programmable device or devices which establish and monitor cross network sessions and for each formatted message, on the session, the programmable device changes the contents on the request unit (RU) and/or the transmission header (TH) fields so that data is delivered to a target LU. The changes include address translation within the TH field, and/or address and name translation within the RU field.
