TCP/IP with the Reliability of
TCP/IP on the mainframe
has been growing in importance over the last few years, and the Visara
1174 has been designed to enable you to take full advantage of these
developments in internetworking; yet still protecting the investment
you have in the 1174 Communication Server. Running as a feature of
the LINCS communications operating system on the 1174, the IP Channel
Bridge allows communications between IP protocol stacks running on
the mainframe and the LAN. The IP Channel Bridge runs concurrently
with any and all other features available on the 1174.
connections to the mainframe, and 100 Mb connections to your network,
ensures that the highest possible throughput between the mainframe
and the LAN is maintained at all times. To enhance this high throughput,
dedicated network interfaces are used for this feature. Concurrent
support for SNA or Non-SNA applications can also be supported through
the same or a second ESCON interface. Multiple LPARs are supported,
up to the maximum number of network cards that can be installed
on the 1174-25S platform (up to 6 Ethernet interfaces, and additional
Token Ring interfaces). Each LPAR uses a dedicated network card
to provide maximum throughput.
The 1174 filters out all non-IP traffic, protecting the mainframe
from extraneous protocols that may be present on the LAN. This ensures
that in a multi-protocol environment the channel only sees the IP
protocol and does not waste cycles sorting the required IP information
from IPX, LAT, LLC or other protocols.
Other LINCS options to reduce load on the host and provide redundant
pathways for sessions include the TN3270 Server and LAN Printing
1174 IP Channel Bridge passes all IP protocols, FTP, SMTP, NFS,
TELNET, TN3270, etc based on the mainframe. So you can be assured
that no matter why or how you wish to use the TCP/IP stack on your
mainframe, the 1174 IP Channel Bridge continues to provide all the
support you require.
The IP Channel Bridge feature is also available through Bus and
Tag connections (up to 2) on the 1174-25S.
