6 IP CIP Migration, Compatibility and Operational
Differences
The same methods of specifying a NonStop TCP/IPv6 transport-service provider are available for
CIP. Once CIP is installed, applications can use CIP by specifying a CIPSAM process name as
their transport-service provider. An application can change transport-service providers while running
and can also have sockets using conventional NonStop TCP/IP, NonStop TCP/IPv6 and CIP at
the same time. (Parallel Library TCP/IP cannot co-exist with NonStop TCP/IPv6.)
This chapter covers:
• “Summary of High-Level Differences Between Previous TCP/IP Subsystems and CIP”
• “Operational Differences Between Previous TCP/IP Subsystems and CIP” (page 175)
• “Application Programming Differences Between NonStop TCP/IPv6 and CIP” (page 188)
• “TCP/IP Attributes in CIP” (page 193)
• “How to Migrate From NonStop TCP/IP or NonStop TCP/IPv6 to CIP” (page 203)
For high-level comparisons of all NonStop networking products, see the NonStop Networking
Overview.
Summary of High-Level Differences Between Previous TCP/IP Subsystems
and CIP
Table 16 summarizes the differences between conventional TCP/IP, Parallel Library TCP/IP,
NonStopTCP/IPv6, and CIP.
NOTE: To find out which servers support these subsystems, see the planning guide for your system
or the NonStop Networking Overview.
