NorNet – A Linux- and Open-Source-Software-based International Platform for Networking Research
The NorNet testbed (https://www.nntb.no) is an Internet testbed platform for research on multi-homed systems. The particular property of multi-homed systems is to be connected to multiple Internet Service Providers (ISP) simultaneously. Its initial purpose is of course to still provide connectivity in case of ISP/network failures. But does it really work that well, also with current protocols and applications? And redundancy does not come for free. A user connected to multiple ISPs will also receive multiple Internet bills each month. So, is there a possibility to make further use of multi-homing in the usual case where nothing goes wrong? Obviously, there are a lot of interesting research questions, which need to be examined in realistic Internet setups! Therefore, we are building up the NorNet open Internet testbed platform as a Linux- and Open-Source-software-based infrastructure, which currently spreads over multiple sites in different countries.
NorNet makes extensive use of advanced Linux features like Kernel-based Virtualisation (KVM), Linux Containers (LXC), BTRFS file system features, IP routing rules, Stream Control Transmission Protocol (SCTP), Multi-Path TCP (MPTCP), and many more. The goal of this talk is therefore to present an overview of the testbed, its underlying Linux features, and how they are combined to provide the multi-homing features to the various testbed users. This particularly includes an overview of how to make use of multi-path transport with MPTCP – based on the Linux MPTCP implementation – in multi-homed environments. The idea is to provide guidelines for also utilising multi-homing features in own projects.

Detecting Issues with In-Band Telemetry in OSM-Orchestrated Core Networks
Open Source MANO is a helpful tool to manage and orchestrate the instantiation of core network setups, like Network Service (NS) instances of our SimulaMet OpenAirInterface Virtual Network Function (VNF) for Enhanced Packet Cores (EPC). We furthermore extended our NS with VNF instances of Programming Protocol-independent Packet Processors (P4) switches, in order to allow for in-band telemetry. With in-band telemetry, it is possible to flexibly add, process, and remove telemetry information to traffic within the packet core, in order to allow for fine-granular evaluation of the system performance and the users' experienced quality of service. In our presentation and demo, we would like to provide an overview of our ongoing work on P4-based in-band telemetry in an OSM-orchestrated 4G core, which is used for detecting performance problems and anomalies in the network based on machine learning. We would furthermore like to demonstrate the details of our setup to the audience in a live demo.

Relative estimates of software development effort: Are they more accurate or less time-consuming to produce than absolute estimates, and to what extent are they person-independent?

Relative estimates of software development effort: Are they more accurate or less time-consuming to produce than absolute estimates, and to what extent are they person-independent?
Context: Estimates of software development effort may be given as judgments of relationships between the use of efforts on different tasks-that is, as relative estimates. The use of relative estimates has increased with the introduction of story points in agile software development contexts.
Objective: This study examines to what extent relative estimates are likely to be more accurate or less time-consuming to produce than absolute software development effort estimates and to what extent relative estimates can be considered developer-independent.
Method: We conducted two experiments. In the first experiment, we collected estimates from 102 professional software developers estimating the same tasks and randomly allocated to providing relative estimates in story points or absolute estimates in work-hours. In the second experiment, we collected the actual efforts of 20 professional software developers completing the same 5 programming tasks and used these to analyze the variance in relative efforts.
Results: The results from the first experiment indicate that the relative estimates were less accurate than the absolute estimates, and that the time consumed completing the estimation work was higher for those using relative estimation, even when only considering developers with extensive prior experience in story point–based estimation for both tasks. The second experiment revealed that the relative effort was far from developer-independent, especially for the least productive developers. This suggests that relative estimates to a large extent are developer-dependent.
Conclusions: Although there may be good reasons for the continued use of relative estimates, we interpret our results as not supporting that the use of relative estimates is connected with higher estimation accuracy or less time consumed on producing the estimates. Neither do our results support a high degree of developer-independence in relative estimates.
