  • Patent number: 4893307
    Abstract: The invention disclosed herein provides the basic operation capabilities of SNA data communications for host-to-remote terminal sessions across a packet switched network such as the Defense Data Network (DDN). The problem that is presented by the integration of these two technologies is that SNA is a connection oriented technology and DDN is a connctionless technology that requires an Internetting Protocol (IP) header on all information transmitted through the network and across multiple networks. One of the concepts of the invention is the definition of a localized SNA network to each SNA host by the channel attached front end processors (FEPs). These FEPs present a SNA LU2 definition to the host to allow it to carry out regular SNA sessions over the packet switched network to remote terminal users. The second concept is providing primary SNA PU5 support, in the Remote Access Facilities (RAF). This enables each RAF to control all the SNA terminals and devices attached to it as a separate network.
