An access device for establishing a Systems Network Architecture (SNA) session between an SNA Client and an SNA application using Telnet 3270 services over a communication network. The communication network, has Telnet 3270 servers for accessing the SNA application. The access device comprises logic for: (1) receiving from a Telnet 3270 client, a request for establishing a Telnet 3270 session with a Telnet 3270 Server, the request comprising an identification of the SNA client associated with the Telnet 3270 client, (2) selecting a communication path within the communication network to access a Telnet 3270 server providing services to the SNA client by referring to a configuration table, which comprising, for each SNA client, one or more communication paths leading to one or more Telnet 3270 servers, and (3) forwarding the Telnet 3270 session request to a selected Telnet 3270 server along the selected communication path.
