NonStop TCP/IPv6 Components
Some components of the NonStop TCP/IPv6 subsystem are not involved in the data
path; they exist for management purposes only. These components include the
TCP6MAN, TCP6SAM, SCF, and PTrace product modules. Figure 2-8 on page 2-12
shows the data paths in NonStop TCP/IPv6 and compares them to the data paths in
conventional TCP/IP.
