Summary of Differences Between NonStop TCP/IP
and NonStop TCP/IPv6
Summary of Differences Between NonStop
TCP/IP and NonStop TCP/IPv6
This subsection summarizes the differences between NonStop TCP/IP and NonStop
TCP/IPv6. It lists behavioral differences but does not compare the architectural
differences between the two subsystems. (Table 1-1 on page 1-2 provides a
comparison of the architectural components of the two subsystems.)
The following alphabetical list of differences between NonStop TCP/IP and NonStop
TCP/IPv6 is organized by a keyword that describes the topic. Cross-references are
provided for further explanation of the topic.
•
Applications: Unless configured with logical network partitioning, subnets are
available to all applications. See Applications: Restricting Access to Network
Interfaces on page 3-2. Also, there are considerations for applications that can be
spawned in any processor. See the Note on page 4-2.
•
Configuration Files: There are required changes to PROTOCOL configuration file
and there is a new configuration file. See Configuration Files on page 3-4.
•
DEFINEs: There are new system DEFINEs. See DEFINEs on page 3-4. Also see
Configuring Applications to Use NonStop TCP/IPv6 on page 2-5.
•
Errors: Errors are handled differently. See Error Treatment on page 3-4.
•
Fault-tolerance: Fault-tolerant behavior is different in some circumstances. See
Fault-Tolerant Behavior on page 3-5. Also see NonStop Operations on page 3-7.
•
Firewall Considerations: There is a migration consideration for firewalls. See
Firewall Considerations on page 3-5.
•
Guardian Socket Migration: There are programming considerations for
enhancing performance when an application migrates a Guardian socket to
another processor. See Management Interfaces on page 3-5.
•
Management Interfaces: There are differences in the SCF and SPI interfaces to
NonStop TCP/IPv6. See Management Interfaces
on page 3-5.
•
Modes: NonStop TCP/IPv6 has three operating modes; NonStop TCP/IP only has
one operating mode. See Modes on page 3-7.
•
NonStop Operations: NonStop TCP/IPv6 supports Ethernet failover which
provides fault-tolerance at the adapter level. See the NonStop Operations on
page 3-7.
•
Persistence Manager: There are differences in how you manage the Persistence
Manager for NonStop TCP/IPv6. See Persistence Manager on page 3-7.
•
Platform: NonStop TCP/IPv6 does not run on NonStop k-series servers. See
Platform on page 3-8
