Layer 6 of the SNA architectural model. This layer provides network resource management, session presentation services, and some application management.
TN3270 Server Protocol
The TN3270 Server is an application available on a Cisco Mainframe Channel Connection (CMCC) card, the Channel Interface Processor (CIP) and Channel Port Adapter (CPA). The TN3270 Server allows TN3270 clients access to IBM and IBM-compatible mainframes without the limitations of existing alternatives. It offloads 100 percent of the TCP/IP and TN3270 cycles from the mainframe, and it offers a robust, scalable, and dynamic implementation that meets the stringent requirements of the data center.
