“…While the high degree of connectivity available in certain areas may limit the consequence of these problems [30], other regions appear to be particularly vulnerable [5,6,36]. The $560-million Asia America Gateway cable (AAG), notorious for frequent breakdowns, connects Southeast Asia and the US, handling over 60% of Vietnam's international Internet traffic.…”

The growth of global Internet traffic has driven an exponential expansion of the submarine cable network, both in terms of the sheer number of links and its total capacity. Today, a complex mesh of hundreds of cables, stretching over 1 million kilometers, connects nearly every corner of the earth and is instrumental in closing the remaining connectivity gaps. Despite the scale and critical role of the submarine network for both business and society at large, our community has mostly ignored it, treating it as a black box in most Internet studies, from connectivity to inter-domain traffic and reliability. We make the case for a new research agenda focused on characterizing the global submarine network and the critical role it plays as a basic component of any inter-continental end-to-end connection.

The increasing evolution of computing technologies has fostered the new intelligent concept of Ubiquitous computing (Ubicomp). Ubicomp environments encompass the introduction of new paradigms, such as Internet of Things (IoT), Mobile computing, and Wearable computing, into communication networks, which demands more efficient strategies to deliver tasks and services, considering heterogeneity, scalability, reliability, and efficient energy consumption of the connected devices. Middlewares have a crucial role to deal with all these aspects, by implementing efficient load balancing methods based on the hardware characterization and the computational cost of the queries and tasks. However, most existing solutions do not take into account both considerations in conjunction. In this context, we propose a methodology to characterize distributed servers, services, and network delays in Ubicomp environments, based on the Server Ability to Answer a Query (SAAQ). To evaluate our SAAQ-based methodology, we implemented a simple middleware in a museum context, in which different IoT devices (e.g., social robots, mobile devices) and distributed servers with different capabilities can participate, and performed a set of experiments in scenarios with diverse hardware and software characteristics. Results show that the middleware is able to distribute queries to servers with adequate capacity, freeing from service requests to devices with hardware restrictions; thus, our SAAQ-based middleware has a good performance regarding throughput (22.52 ms for web queries), end-to-end delay communications (up to 193.30 ms between San Francisco and Amsterdam), and good management of computing resources (up to 80% of CPU consumption).

A system for profiling the IXPs in a region and monitoring their growth: Spotlight at the internet frontier

This work aims at designing and implementing a system able to profile and help manage the set of Internet eXchange Points (IXPs) in an Internet region.As part of the Internet Society's strategy to help monitor and understand the evolution of IXPs in a particular region, a route-collector data analyzer tool was developed before being deployed and tested in AfriNIC. In fact, traffic localization efforts in the African peering ecosystem would be more sustained, and their efficacy assessed if they were supported by a platform, which evaluates and reports in real time about their impact on the Internet. We, thus, built the "African" Route-collectors Data Analyzer (ARDA), an open source web platform for analyzing publicly available routing information collected since 2005, by local route-collectors. ARDA evaluates predefined metrics that picture the status of the interconnection at local, national, and regional levels. It shows that a small proportion of AfriNIC ASes (roughly 17%) are peering in the region. Through them, 58% of all African networks are visible at one IXP or more. These have been static from April to September 2017, and even February 2018, underlining the need for increased efforts to improve local interconnectivity. We show how ARDA can help detect the impact of policies on the growth of local IXPs or continually provide the community with up-to-date empirical data on the evolution of the IXP substrate. Given its features, this tool will be a helpful compass for stakeholders in the quest for better traffic localization and new interconnection opportunities in the targeted region.
