| Description | This table provides information on the traffic in MUS
for each processor in both directions. Any MSU in which
a processor is involved will be counted. Here are some
examples of how MSUs would be counted.
Traditional SS7 Links:
MSU is received on Line card 1 that supports SS7 link and
MSU is routed directly to line card 2 that supports output
link. Line card 1 processor information will be updated to
indicate it received MSU and line card 2 processor
information will be updated to indicate it sent MSU.
IP/SCTP based SS7 Links:
IP based SS7 Links can be terminated on linecard or owned
by the main processor. When SS7 link is terminated on main
processor only the main processor information will be
updated. The line card processor that owns the IP interface
will be involved but will not be included in measurements.
When the SS7 link is terminated on line card its processor
information will be updated.
It is important to note that packets exchanged for SCTP
associations are different from SS7 MSUs. More than one
SS7 MSU can be transmitted in a single IP packet. Also,
the SCTP association exchanges control packets that are
not counted as SS7 MSUs. |
