“Routing and dependability 2014” ends – Results

The “Routing and dependability 2014” was completed at the end of 2014. This post summarises work address in the project and results output.

  • Interdomain measurements:  Active intra-domain (within UNINETT)  inter-domain measurements  were performed during a few month time period as part of the ongoing  Dragon-lab initiative. Intra-domain data collected was analysed, and anomalies on the micro second level was investigated. The overall measurements infrastructure combined with the analysis technique proved to be able to detect miss-behaving routers in some of the measurement paths [1]. Thin stream aspect has also been investigated base on intra-domain traffic data supplied by UNINETT [2].  Collected Inter-domain data was also to some extent studied, see next paragraph.
  • Dependability analysis: Active inter-domain measurement data was applied to present a case study in a scientific paper addressing and analysing availability guarantees [3]. More in-depth analysis of UNINETT’s network and systems infrastructures was not pursed to any extent during the project period. Such analysis are still considered very relevant and need to be given priority in upcoming innovation activities.
  • Software Defined Networking (SDN): The majority of efforts spend in the “Routing and dependability” project were focused towards Software Defined Networking (SDN) investigations. UNINETT supported (and still supports) a Phd student at Univerity of Stavanger in his research on SDN [4]. Topics within SDN based network monitoring, SDN “slicing” for multi-tendent support, and SDN security have been studied and ideas published. A Msc thesis from NTNU studying stochastic routing with SDN was completed in 2013 [5]. A alternative stochastic implementation of the “select” function in the Open Flow standard was suggested and evaluated. During the summer 2013 UNINETT participated in Hewlett Packard’s beta testing program for Open Flow 1.3 switch firmware. Even though all functional tests were successful the switching performance experienced was disappointingly far below the switch line speed (<100Mbps on a 1Gbps switch).
  • UNINETT’s SDN lab infrastructure: In cooperation with UiS and UNIK, UNINETT has work on establishing a small lab infrastructure for SDN experimentation [6]. A fully meshed (triangular) topology with a data-centre-like node at UiS in Stavanger, at UNIK outside Oslo and at UNINETT in Trondheim has been the target. Efforts have been spent in configuring nodes as mini-data-centres based on the Open Stack framework. Traffic between the Open stack nodes is to be switched by an SDN controlled network. The lab infrastructure was only partly operational when the project ended, however the efforts will be continued in an upcoming SDN project. As a result of the work on the lab infrastructure UNINETT has a formal collaboration with Transpacket [7] in developing next generation 10Gbps SDN enabled switching equipment.
  • SDN workshops: The project has offered two very successful workshops, one in March 2014 [8] and one in October 2014 [9], where both academic and commercial collaborator attended.
