I have a question on an aspect of behaviour relating to Link Group IDs
in fault localization in LMP-WDM.
The LMP-WDM spec section 2.4 states the following:
Each data link is identified by an Interface_ID. In addition, a Link
Group ID may be assigned to a group of data links (see Section
2.3.1). The Link Group ID may be used to reduce the control traffic
by providing channel status information for a group of data links. A
new LINK GROUP CHANNEL_STATUS object is defined below for this
purpose. This object may be used in place of the CHANNEL_STATUS
objects described in [RFC4204] in the ChannelStatus message.
This specifies that the Link Group IDs may be present in ChannelStatus
messages but not the ChannelStatusRequest message.
So say we send a ChannelStatus message containing a Link Group ID to the
upstream node. If an Ack is not received or we do not receive a
corresponding ChannelStatusMessage result then when we prompt the
upstream node with a ChannelStatusRequest message we need to use the
interface ids of the datalinks contained in the Link Group ID rather
than the Link Group ID itself.
Is this the intended behaviour ?
