Single IP
By eliminating message-system hops, NonStop TCP/IPv6 reduces the total path length
from the application to the wire. This path-length reduction reduces individual request
latency. In addition, throughput is higher because more requests can be serviced each
second without increasing processor cost.
Single IP
In conventional TCP/IP, you had a limited ability to scale a listening application; if you
wanted to run different instances of the application in different processors and using
different TCP/IP processes, you would have to do so on different IP addresses. Each
TCP/IP process appeared as a unique IP host to the outside world, as shown in
Figure 2-3
on page 2-5.
