Abstract

There has been a rapid rise in the IP traffic
throughout the Internet which takes advantage of the already
established widespread IP infrastructure. Different suggestions
are being explored to facilitate the next-generation access net-
works via IP mechanisms, with a growing trend towards a
flat-IP structure and novel topological set-ups in the backhaul.
Aligned with this evolution, there are increasingly more user
applications flooding the Internet that calls for a consistent
routing strategy to minimize loss in data transmission. In this
paper, Multi-Plane Routing (MPR), which incorporates various
aspects in all-IP infrastructure will be studied under the new
access network structure. MPR is based on Multi-Topology Open
Shortest Path First (MT-OSPF) principle and divides the physical
network topology into several logical Routing Planes (RPs). The
offline Traffic Engineering (TE) strategy for MPR has been
optimized using a heuristic hop-constraint solution that suits
the “flattened” network realized through the incorporation of
direct communication between Aggregation Routers. With our
approach, despite of a higher number of Ingress−Egress pairs
for traffic in the access network, the number of RPs has been
kept to the desirable level whilst the reliability indicator and
the path diversity index ratio have increased up to 47% and
33% respectively. Our proposed MPR-based offline approach has
also shown improvement compared with the Multi-Protocol Label
Switching (MPLS) offline approach.
