Problem description: Most network devices today have the control and data plane within the same physical unit. The individual deveices have little-to-know knowledge of the state of the rest of the network, and makes forwarding decisions based upon the little formation it have.

An emerging architecture to solve this is known as software defined networking (SDN), and is done by separating the control plane and the data plane. One of the leading SDN architectures is OpenFlow, where the control plane is a software running on centralized units. The OpenFlow controller has full knowledge of the entire network, and can make forwarding decisions based on this. When looking at OpenFlow, we want to find out how it can be used for traffic engineering, so that we can maximize utilization of network links. We want to look at how the security is implemented by centralizing the forwarding decision, and how redundancy is achieved.

Methods and Tools: The tools and methods in this thesis are based on
  • A set of scenario, describing the challenges
  • A list of requirements being extracted from the scenarios
  • A description and evaluation of technologies and tools being candidates for solutions
  • A functional architecture/description of the envisaged system
  • An implementation of the core concepts
  • A demonstration of the solution
  • An evaluation of the solution, including a critical review of the descisions taken earlier
  • Conclusions
  • References
Time schedule The envisaged time schedule (for a long thesis/60 ECTS) is:
T0 0 starting month, T0+m denotes the month where the contribution to a certain chapter shalle be finalized
T0+2 months: create an initial page describing the scenario
T0+3: Provide a list of technologies which you think are necessary for the thesis
T0+4: Establish the table of content (TOC) of the envisaged thesis. Each section shall contain 3-10 keywords describing the content of that section
T0+7: Provide a draft of section 2 (scenario) and 3 (technologies)
T0+10: Establish a draft on what to implement/architecture
T0+11: Set-up an implementation, testing and evaluation plan
T0+15: Evaluate your solution based on a set of parameters, keep in mind there is no such thing as a free lunch
T0+17: Deliver the thesis
Pre-Knowledge This thesis includes a reasonable amount of programming. The envisaged thesis is based on radio communications, thus expects the user to have followed at least two radio-related courses
Approved Pending by
Keywords Software defined network, IPv6
