Re: [CCAMP] Microwave topology

[Daniele Ceccarelli <[e-mail]>]

Hi Jonas,

 

Could you please elaborate this question a bit more?

 

"When creating a TE connection (LSP), should all necessary information
(bandwidth, latency, availability, etc) be available in the 1st level
resources used (IGP Links), or should the PCE always query all underlaying
layers for additional information?"

 

Are you referring to a multilayer scenario in which the IP/MPLS link is the
client and there is a number of physical layers below? If my understanding
is correct I would say that the info needs to be available at the client
layer as the PCE might not have the capability to retrieve the information
from the lower layers (and in many cases doesn't have awareness at all of
them).

 

Cheers,

 

 

Daniele

Hi all,

 

I have created an example which I hope can be used as a basis for the
continued discussion. See attachment.

I've also added a few questions which I believe are important to discuss in
order to create a better understanding of how we best model the unique
characteristics of a microwave radio link.

 

Regards

Hi all,

 

Short notes from our discussion today.

 

Please remember that the meeting time has been changed.

 

*	The meeting continued the discussion about the applicability of
te-topology concepts and the benefits of augmenting te-topology v.s.
network-topology. The meeting concluded that most of the discussions require
a refinement/clarification of the use cases to be supported by the model. It
was decided that it should be the focus for the coming week and be discussed
and agreed on the next meeting.
*	The use cases mentioned (and which need to be further refined) are:

*	L1 microwave radio link topology discovery

*	Illustrate how radio link topology can co-exist with other L1
technologies

*	End-to-end L2 service creation over a L1 topologies, including
microwave radio link and L1 connectivity for interconnection between the
radio links

*	Show cases with and without bandwidth reservation

*	Use case showing how microwave radio link could support higher order
layers such IP/MPLS (other than L2).

 

Attached is a presentation showing earlier discussions about use-cases.
