Enquadramento
The master's thesis work would consist in developing an OpenFlow controller application (in OpenDayLight) that supports multipath routing and QoS mechanisms.
Objetivo
We would focus on the performance of Multipath TCP over different multipath routing strategies. We would evaluate different network path calculation strategies:
• Single path routing (where all MPTCP sub-flows from a source to a destination share a single path)
• Bottleneck disjoint multi-path calculation, based on the usage of shortest path routing metric. Here, each subflow will be routed across a different network path potentially being bottleneck disjoint. We will evaluate different path allocation strategies like Round-Robin, Randomn, etc.
• Low latency aware path selection, with additional data regarding the existent QoS mechanisms in OpenFlow switches (e.g. OpenvSwitch).
Upon the path calculation, the application should be able to configure and install appropriate OpenFlow forwarding rules in the existing devices.
Additionally, in order to integrate the usage of Multipath TCP in Software Defined Networking, a cross-layer interaction between SDN and MPTCP's congestion control would be developed, where after identifying the existence of MPTCP traffic, the flow calculation optimization would install the required forwarding rules, prior to the initiation of the respective MPTCP sub-flows. The idea is that such proactive flow rule installation saves startup time which should be beneficial especially to short-lived flows.
Finally, we will compare the performance of the different strategies using our previously developed CORE network emulator platform.
