RE: Switching Capability of Photonic Links with Transponder

["MEURIC Julien RD-CORE-LAN" <julien.meuric@orange-ftgroup.com>]

Hi Diego.

If I understand correctly, your "lambda switch" by itself is a PXC that
has only "Fiber-Switch Capable" interfaces. Then, you add
lambda-conversion cards to it. So, correct me if I'm wrong (you or
anyone else), but whether you do a lambda conversion inside a card or in
a core matrix, this new interface on your global device is able to work
on lambdas anyway  [(lambda 1, port A) --> (lambda2, port B)]. As a
result, you need to advertise your most flexible capability, which is
"Lambda Switch Capable".
If you used "FSC", you wouldn't be able to control your "lambda
swapping" card, as LSPs are like lists of fibers and labels aren't
wavelengths but ports.

But maybe I didn't get your actual issue.

My 2 cents,

Julien

Hi all,

         I've a doubt about how to model the following situation.

 

 

 

      +-----------------+

      |                 |-------+

      |                 | OEO   |

      |     Lambda      |-------+

      |     Switch      |

      |                 |

      |                 |

      +-----------------+

      

 

The node itself is able to cross connect only the Lambda while the
interface has a OEO transponder that is able to change the lambda
frequency.  In this case there are two different 'switching capability'
the spatial one that is performed by the switch (lambda 1, port A) -->
(lambda1, port B) and the frequency switching is done by the OEO
transponder.  Witch kind of interface switching capability I have to
advertise?
