trac.

So,

the

test

trac

transferred

along

the

path

is

issued

and

controlled

by

the

measure-

ment

•

In

the

runtime

mode,

the

measurement

trac

runs

in

parallel

with

the

runtime

automation

traf-

c,

thus

it

has

to

be

assured

that

the

measurement

does

not

impact

the

runtime

automation

trac.

e

monitoring

can

be

used

to

measure

the

current

network

parameter

values

and

to

identify

whether

the

provider

network

meets

the

agreed

limits

contracted

in

the

SLA.
