Enquadramento
The main objective of the work to be performed is the study of the capabilities of the Software Defined Networking (SDN) approach based on OpenFlow (OF) to support low latency datacenter traffic.
Controlling the routing and forwarding behavior of routers and switches in a fine granular and scalable way, make this technology a strong candidate for flexible datacenter networking needed in e.g. Cloud Infrastructures. However, current OpenFlow does not really support latency awareness and dynamic creation of low latency paths within datacenters still is an open research topic. This project aims at studying the feasibility of using Software Defined Networking in the context of Public and Private Cloud deployments, where the focus is on low latency applications. Low latency applications are becoming more and more important such as demonstrated by the increased interest in interactive gaming, real-time stock trading or real-time multimedia. Such services are considered to be an important candidate to be deployed in the Cloud in the near future. Therefore, the Cloud Infrastructure needs to support low latency on demand networking.
Objetivo
The main objective of the work to be performed is to study the capabilities of the Software Defined Networking approach based on OpenFlow to support low latency on demand routing and forwarding services for next generation datacenters. The student must analyse the OpenFlow technology, including how to implement networking applications on OpenFlow Controllers such as NOX/POX or similar. An application needs to be implemented on an OpenFlow Controller that establishes customized forwarding rules and configures the network in such a way to provide paths with low latency. This includes the control of the queues at the OpenFlow enabled routers. The student must develop a mathematical model, which allows him to derive a network configuration that fulfills the user requirements in terms of latency and bandwidth needed. This model needs to be connected to the application, which runs on the OpenFlow Controllers. In order to evaluate the system, student needs to become familiar with network emulators such as Mininet or Immunes. The system is supposed to be evaluated with multipath transport protocol MPTCP where different subflow scheduling approaches should be used.
Plano de Trabalhos - Semestre 1
Phase 1 - Study of state-of-the art on Software Defined Networking, OpenFlow, NOX/POX as well as Mininet/Immunes network emulators. A small test emulation of a datacenter should be created in such emulator and some rules should be configured and the impact of performance should be evaluated. (01/09/2013 – 30/11/2013)
Phase 2 – Model Development for Low Latency on Demand Path Selection (01/11/2013 – 31/12/2013)
Phase 3 - Writing of first semester report (01/01/2014 – UC delivery deadline)
