Besides CCR, these artifacts were rarely evaluated. During the last months of 2018, we organised two different Artifacts Evaluation Committees to which authors could submit the artifacts of their papers for evaluation. The first one evaluated the papers accepted by Conext’18 shortly after the TPC decision. It assigned ACM reproducibility badges to 12 different papers. The second one evaluated papers accepted by CCR and any SIGCOMM-sponsored conference. 28 papers received ACM reproducibility badges. We report on the results of a short survey among artifacts authors and reviewers and provide some suggestions for future artifacts evaluations.","PeriodicalId":403234,"journal":{"name":"Comput.

However, such hybrid data centers are currently limited by a restrictive routing policy enforcing artificial segregation: each network flow can only use either the static or the flexible topology, but not a combination of the two.\u0000 This paper explores the algorithmic problem of supporting more general routing policies, which are not limited by segregation. While the potential benefits of non-segregated routing have been demonstrated in recent work, the underlying algorithmic complexity is not well-understood.\u0000 We present a range of novel results on the algorithmic complexity of non-segregated routing. In particular, we show that in certain specific scenarios, optimal data center topologies with nonsegregated routing policies can be computed in polynomial-time. In many variants of the problem, however, introducing a more flexible routing comes at a price of complexity: we prove several important variants to be NP-hard.","PeriodicalId":403234,"journal":{"name":"Comput.

This workshop series provides a forum for researchers, Internet facilities and service providers, technologists, economists, theorists, policy makers, and other stakeholders to exchange views on current and emerging regulatory and policy debates. To add clarity to a range of vigorous policy debates, and in pursuit of actionable objectives, this year’s meeting used a different approach to structuring the agenda. Each attendee chose a specific policy goal or harm, and structured their presentation to answer three questions: (1) What data is needed to measure progress toward/away from this goal/harm? (2) What methods do you propose to gather such data? (3) Who are the right entities to gather such data, and how should such data be managed and shared? With a specific focus on measurement challenges, the topics we discussed included: analyzing the evolution of the Internet in a layered-platform context to gain new insights; measurement and analysis of economic impacts of new technologies using old tools; security and trustworthiness, reach (universal service) and reachability, sustainability of investment into Internet infrastructure, as well as infrastructure to measure the Internet.

It serves as the basis for making a variety of management decisions for improving the performance, availability, security, and efficiency of networks. However, it is challenging to build real-time and fine-grained network telemetry systems because of the need to support a variety of measurement queries, handle a large amount of traffic for large networks, while staying within the resource constraints at hosts and switches. Today, most operators take a bottom-up approach by passively collecting data from individual devices and infer the network-wide information they need. They are often limited by the monitoring tools device vendors provide and find it hard to extract useful information. In this paper, we argue for a top-down approach: We should provide a high-level declarative abstraction for operators to specify measurement queries, programmable measurement primitives at switches and hosts, and a runtime that translates the high-level queries into low-level API calls. We discuss a few recent works taking this top-down approach and call for more research in this direction.","PeriodicalId":403234,"journal":{"name":"Comput. Commun.
