Abstract:
Versatile applications over the Internet are producing unprecedented
volume of data, flowing across the independently managed networking
domains. Requirement of reliable communication, with better
throughput and moderate latency, encourages Internet Service
Providers to increase peering relationships with its immediate neighbors
and beyond. Growing number of peering participants over
emerging Internet Exchange Points (IXPs) highlights the significance
of topological arrangement across the domains. IXPs are not
only simplifying peering mesh of neighboring domains but also flattening
the Internet topology from hierarchical structures over the
course of time. Recent research works reveal the average edge multiplicity
between IXPs more than four edges and entire range of IPv4
prefixes reachable through IXPs interconnection. Moreover, IXPs
are adopting Software Define Networking (SDN) driven switching
fabric, a trend that is becoming prominent with Toulouse, France
and Tokyo, Japan Internet exchanges being clear case examples. In

this thesis, we propose an architecture that interconnects SDN driven
switching fabric of IXPs and exploit edge multiplicity between them
to provision services across domains for the IXP peering participants.
Traffic Engineering steered and policy compliant appropriate
multiple paths are searched in a joint fashion to deploy at the IXPs
switching fabric. We demonstrate that our proposal helps to achieve
communication reliability across the domains with better network
performance parameters like 54.60% increase in throughput.
