As shown in table Table 1, some protocols can be used only for certain types of client/server connection. Access to 3270-based CICS® transactions might require an SNA connection. SNA network connections are the recommended approach, because they can be routed over IP networks using the SNA Remote API Client or Enterprise Extender and they do not require complex AnyNet® definitions.
For information on continuing AnyNet support in z/OS® Communications Server, refer to the information in the z/OS Statements of direction announcement, Software Announcement 203-266, dated October 7, 2003, and the z/OS V1.7 preview announcement, Software Announcement 205-034, dated February 15, 2005.
