Instance.
Description
The ID of the APS. Maximum number of creatable APS instances is 10 . Click on
link to get to APS instance page, you can reset counters and issue commands.
The Port this flow is attached to.
Selects whether Signal Fail (SF) comes from the link state of a given Port, or
from a Down-MEP.
The Domain::Service::MEPID refers to a MEP instance which shall represent the
Working flow. Only used when SF Trigger is MEP. The selected MEP instance
does not need to exist when this APS is configured.
1:1 This will create a 1:1 APS.
In the linear 1:1 protection switching architecture, the protection transport entity
is dedicated to the working transport entity. However, the normal traffic is
transported either on the working transport entity or on the protection transport
entity using a selector bridge at the source of the protected domain. The selector
at the sink of the protected domain selects the entity which carries the normal
traffic.
1+1 Uni This will create a 1+1 Unidirectional APS.
1+1 Bi This will create a 1+1 Bidirectional APS.
In the linear 1+1 protection switching architecture, a protection transport entity is
dedicated to each working transport entity. The normal traffic is copied and fed to
both working and protection transport entities with a permanent bridge at the
source of the protected domain. The traffic on working and protection transport
entities is transmitted simultaneously to the sink of the protected domain, where
a selection between the working and protection transport entities is made based
on some predetermined criteria, such as server defect indication.
