Several large-scale Internet measurement systems have been deployed during the last years in order to understand how the network is performing, to observe how it is evolving, and to determine where failures or degradations occur. Large-scale measurements are meanwhile used to drive network operations and to dynamically adjust how services are delivered to customers. One key challenge is that global Internet measurement systems can generate large amounts of data that need to be processed to derive relevant information.
This Dagstuhl Seminar is a follow-up of Dagstuhl Seminar 13472 “Global Measurement Frameworks” that took place in November 2013. It aims at discussing the practical experience gained with global measurement frameworks and it will look at the experience gained with metrics, data processing technologies, and data analysis methods. Starting from these three dimensions, the seminar aims to discuss the following key questions:
Measurement Metrics
- Which metrics have been found useful for measuring quality of experience of certain classes of services?
- Which metrics have been found problematic?
- Is it possible to find indicators for good metrics and problematic metrics?
- Is it possible to formulate guidelines for the development of robust metrics?
Data Processing Technologies
- Which technologies have been found useful for storing and processing large amounts of measurement data?
- Which technologies were found to be problematic?
- Are there new promising technologies being developed that may be used in the future?
- What are the specific requirements for dealing with global measurement data and how do they relate to or differ from other big data applications?
Data Analysis Methods
- Which data analysis techniques have been found useful?
- Which data analysis techniques have been found problematic?
- Are there any novel promising techniques that need further research and development?
Several large-scale Internet measurement platforms have been deployed during the last years in order to understand how the Internet is performing, to observe how it is evolving, and to determine where failures or degradations occur. Examples are the CAIDA Archipelago (Ark) platform [6] (used for Internet topology discovery and detecting congestion on interdomain links), the SamKnows platform [4] (used by regulators and network operators to study network performance), the RIPE Atlas platform [3, 5] (that provides measurement services to network operators and researchers), the Netradar system [8] (for performing wireless performance measurements), and the BISmark project [9]. European collaborative research incorporate measurement results into network management systems (e.g., Leone) [2]. Related projects (e.g., Flamingo) [1] are increasingly working with measurement data from these platforms. Large-scale measurements are meanwhile also used to drive network operations or to dynamically adjust how services are delivered to customers. Content Delivery Network (CDN) providers use measurement data to optimize content caches and to tune load balancing algorithms. One key challenge is that global Internet measurement systems can generate large amounts of data that need to be processed to derive relevant information.
This seminar (#16012) was a followup of the Dagstuhl seminar on Global Measurement Frameworks (#13472) [7]. The main focus of the first seminar was an exchange of ideas on the development of global measurement infrastructures, frameworks and associated metrics. Some of this work is now further pursued in standardization bodies [4] such as the IETF Large-Scale Measurement of Broadband Performance (LMAP) working group and the Broadband Forum. The goal of this followup seminar was to focus on the experience obtained with different metrics, tools, and data analysis techniques. It provided a forum for researchers to exchange their experience with different practices to conduct global measurements. The aim was to identify what works well in certain contexts, what has proven problematic in other contexts, and identify open issues that need further research. The seminar approached this by looking at three distinct dimensions: (a) Measurement metrics, (b) data processing technologies and (c) data analysis methodologies. Some key questions were:
- Which metrics have been found useful for measuring Quality of Experience (QoE) of certain classes of services? Which metrics have been found problematic? Is it possible to find indicators for good metrics and problematic metrics?
- Which technologies have been found useful for storing and processing large amounts of measurement data? Which technologies were found to be problematic? Are there new promising technologies that may be used in the future? What are the specific requirements for dealing with large-scale measurement data and how do they relate to or differ from other big data applications?
- Which data analysis techniques have been found to be useful? Which data analysis techniques have been found to be problematic? Are there any novel promising techniques that need further research and development?
Although at the seminar the participants chose to organize the discussions on more general topics than these specific questions, during the discussions most of these questions were addressed to one degree or another.
