From G.800: 6.4.1 Partitioning of a topological component When addressing the partitioning of topological components, both the topological and resource aspects of the components must be considered. A subnetwork may be recursively partitioned to a degree such that the resultant subnetwork is considered to be in a single (spatial) location, and
Hi Freek, I have spotted the following clause in G.800 on 'recursive partitioning'. This is an important concept an allows for what has been described in the NSI-WG as 'aggregation'. i.e the aggregation of a domain or a group of nodes (subnetwork in G.800 terms) down to a node. This is an important concept for NSI so I would like to see this incorporated into NML. therefore further partitioning does not result in the ability to add any more precision to the location information. At this level of partitioning, the subnetwork is considered to be a node. Note that a node is not necessarily the limit of recursive partitioning, of a subnetwork. Further, depending on the network implementation, it may not be possible to partition a subnetwork to the level of a node. For example, if a subnetwork belongs to a different administration and the policy of that administration is not to allow other administrations to see internal structure, or where the subnetwork is supported by a server layer that uses destination-based forwarding as described in clause 6.5.2.
