Network design process is a very important in order to
balance between the investment in the network and the supervises
offered to the network user, taking into consideration, both
minimizing the network investment cost, on the other hand,
maximizing the quality of service offered to the customers as well.
Partitioning the network to smaller sub-networks called clusters is
required during the design process in order to ease studying the
whole network and achieve the design process as a trade-off
between several attributes such as quality of service, reliability,
cost, and management. Under Clustered Architecture for Nodes in
an Optical Network (CANON), a large scale optical network is
partitioned into a number of geographically limited areas taking
into account many different criteria like administrative domains,
topological characteristics, traffic patterns, legacy infrastructure etc.
An important consideration is that each of these clusters is
comprised of a group of nodes in geographical proximity. The
clusters can coincide with administrative domains but there could
be many cases where two or more clusters belong to the same
administrative domain. Therefore, in the most general case the
partitioning into specific clusters can be either an off-line or an online
process. In this work only the off-line case is considered. In
this Study, we look at the problem of designing efficient 2-level
Hierarchical Optical Networks (HON), in the context of network
costs optimization. 2-level HON paradigm only has local rings to
connect disjoint sets of nodes and a global sub-mesh to interconnect
all the local rings. We present a Hierarchical algorithm that is based
on two phases. We present results for scenarios containing a set of
real optical topologies.
