Abstract
A method and system for establishing a Systems Network Architecture (SNA) session between SNA resources through a packet/cell switching network. The packet/cell switching network includes an origin access node that provides client access services, and at least one destination access node that provides server access services. In accordance with the method of the present invention a SNA session request is received from a source SNA resource for establishing an SNA session with a target SNA resource. An undirected message is broadcast over the packet/cell switching network to identify the destination access nodes that support the source SNA resource and that provide server access services. One or more positive replies are received from respectively one or more of the destination access nodes that support the source SNA resource and that provide server access services. As part of the receiving step, information relating to a traffic handling capacity of the destination access node and information related to establishment of a connection between the origin access node and the destination access node is retrieved. Finally, a destination access node is selected in accordance with the information describing the destination node and in accordance with the information related to establishment of a connection between the origin access node and the destination node.
