Abstract:
Pseudowires (PWs) have become a common mechanism for tunneling
traffic, and may be found in unmanaged scenarios competing for
network resources both with other PWs and with non-PW traffic, such
as TCP/IP flows. It is thus worthwhile specifying under what
conditions such competition is safe, i.e., the PW traffic does not
significantly harm other traffic or contribute more than it should to
congestion. We conclude that PWs transporting responsive traffic
behave as desired without the need for additional mechanisms. For
inelastic PWs (such as TDM PWs) we derive a bound under which such
PWs consume no more network capacity than a TCP flow. We also
propose employing a transport circuit breaker
[I-D.fairhurst-tsvwg-circuit-breaker] that shuts down a TDM PW
consistently surpassing this bound, as the emulated TDM service
itself would be be of insufficient quality.
