Hi Ping,
(6) OAM and OAM interworking: How would it work? Actually, would
carriers allow the OAM packets going over the boundary of the
network?
If I am a carrier, I probably will not allow some guys on
either end of
my network to run some performance monitoring tests. Then how
do we get
edge-to-edge OAM?
An OAM architecture similar to IEEE 802.1ag or ITU Y.17ethoam, might be
useful. In these drafts the OAM flows are divided to 3 spaces:
- User OAM
- Network Operator (Carrier) OAM
- Service Provider OAM
Service provider contracts with a number of carriers to provide the service.
Service provider is responsible for e-2-e performance, and has access to
e-2-e OAM. While each carrier can only run OAM in its own network. This architecture
requires a method to distinguish/filter these 3 types of OAM flows.
Yours,
Shahram
