I wonder exact meaning of the path retransmit and assoc retransmit in "show cs7 asp detail"
SG1#sh cs asp detail

I think "Path retrans = 4" means time of re-try for each path(primary path, secondary path)
and "Assoc retrans = 10" means time of re-try for association.
if assocation has primary and secondary path(it has two paths)and both path is not available in the far-end.
ITP will try to transmit the chunk(packet) to SEP(Signaling End Point)
first it try into the primary path => would be fail because the far-end down.
second it try into the secondary path => would be fail because the far-end down.
above operation will repeat 4 times.
then itp(SG:signaling gateway) will knows every path is not available.
then what is the "Assoc retrans = 10", is it the sum of the fail(primary path fail + secondary path fail)
primary path fail = 4
secondary path fail = 4
association fail = 8 (as I think!!)
what is the exact meaning of "the Assoc retrans = 10"??
who knows about this?
