Hello,

In an article on "measuring" the Internet:

Chaque application a des besoins en termes de "délai, débit, perte",
le fameux triptyque pour les réseaux informatiques de nouvelle
génération.

What would be "délai, débit, perte"? Can I say "delay, throughput,
loss"?

Agreed for delay and loss.

For "débit", you can have either "throughput" or "bit rate".

Throughput (or transfer rate) in data transmission is the
amount of data moved successfully from one place to another
in a given time period.

For data networks, throughput is usually measured in
number of bits per second (bps) that are transmitted,
also quoted as Kilobits per second (Kbps) or Megabits
per second (Mbps).

Bitrate : The number of bits transmitted per unit of time.
Usually expressed in bits per second, or bps.

Throughput is generally lower than bit rate due to
transmission losses. Throughput measures the amount of
data transmitted *succesfully*.

Later on in the same article:

-------------------
Il est important de décomposer les mesures en deux nouvelles classes :

–les mesures de bout en bout, qui concernent le triptyque "délai,
débit, perte" entre deux utilisateurs terminaux ;

–les mesures de proche en proche, qui concernent le triptyque "délai,
débit, perte" entre des nœuds intermédiaires du réseau (routeurs,
commutateurs, passerelles, etc.).
---------------------

Here "bout en bout" would be "end to end". What would be "proche en
proche" in this context?

I would say hop-by-hop.
