Round-Robin Filtering

Parallel Library TCP/IP provides a new feature that enables listening applications

running in different processors and sharing the same port (LIF) to share incoming

connections. For information about this feature, see the TCP/IP (Parallel Library)

Configuration and Management Manual.

Shared Run-Time Library (SRL)

Parallel Library TCP/IP places most of the protocol stack in a private SRL rather than

in a process. Users of ZTCPSRL transparently use the QIO functions without having to

explicitly issue calls to initialize the QIO segment. This architecture allows TCP/IP to

retain its context during processing and shortens the path length. This library is

dynamically loaded into the application’s process space as soon as the application

issues a TCP/IP socket request.

SNMP

The Simple Network Management Protocol (SNMP) as of G06.12.

SPI Interface

For configuration compatibility, TCPSAM supports a subset of SPI objects and

commands. TCPSAM supports the PROCESS, SUBNET, and ROUTE objects but not

ENTRY, ADDRMAP, and SERVER objects. TCPSAM supports only nonsensitive SPI

commands and a few sensitive commands such as ABORT, STOP, PRIMARY, and

TRACE on the PROCESS object (these commands are also supported by

conventional TCP/IP).

SWAN

To use Parallel Library TCP/IP for SWAN applications, enter the name of the TCPSAM

process for the transport service provider name. For information about how to create a

TCPSAM process as well as how to determine the names of the TCPSAM processes

that are already created, see the TCP/IP (Parallel Library) Configuration and

Management Manual. The TCP/IP (Parallel Library) Configuration and Management

Manual also documents the WAN subsystem configuration requirements for using

Parallel Library TCP/IP.

Telserv

If Telserv is running as a fault-tolerant pair in Parallel Library TCP/IP environments, all

the configured Telserv's STATIC service and STATIC window information is captured

Caution. Parallel Library TCP/IP uses a private SRL. If you run programs that use private

SRLs and you are running Parallel Library TCP/IP, do not create private SRLs that overlap the

following memory segments: 0x75800000-0X759FFFFF and 0x7FE00000 - 0x7FE1FFFF. In

addition, QIO reserves 0x20000000 - 0x41FFFFFF.
