CORBA 2.6 Administration Guide

There is one Comm Server per port, limiting throughput on that port.●
There is a TCP/IP process between the ServerNet adapter and a Comm Server, requiring a message system hop.●
Figure 1.3. Original TCP/IP
Each Fast Ethernet ServerNet Adapter (FESA) corresponds to a TCP/IP port.
By comparison, configuring the IIOP connectivity components of your system to use Parallel Library TCP/IP allows
publishing a single port for up to 16 Comm Server processes. Message system hops are reduced by moving execution of TCP
data-path functions from the TCP/IP process into the user process (Comm Server in this case), referencing the Parallel
Library TCP/IP SRL.
