Part of the activities done at LACNIC Labs involve the gathering, processing, and presentation of different kinds of Internet-related metrics. These metrics include IPv6 penetration measurements, internet numbers metrics, RPKI deployment, Internet security metrics, and Internet connectivity measurements. These tasks usually end up in getter a better insight of the regional Internet, are input regional actors, and are made available via open datasets to the community in general.
In this talk Juan Carlos will provide an overview of the recent efforts that are taking place in IETF and IEEE 802 to address privacy concerns. The talk concentrates on lower layers (e.g. Layer 3 and below), where some well know issues will be identified. A description of a Wi-Fi privacy experiment carried out at the IETF and IEEE 802 meetings will also be provided, together with results of the experiment and next steps.
Large-scale measurements: use cases and the LMAP framework -- Philip Eardley (BT’s Networks Research team)
Measuring broadband performance on a large scale is important for network diagnostics by providers and users, as well as for public policy. The LMAP framework provides a logical architecture, which assists standardisation of the key protocols that coordinate interactions between the components.
Informing Protocol Design Through Crowdsourcing: the Case of Pervasive Encryption -- Marcelo Bagnulo (UC3M)
Middleboxes, such as proxies, firewalls and NATs play an important role in the modern Internet ecosystem. On one hand, they perform advanced functions, e.g. traffic shaping, security or enhancing application performance. On the other hand, they turn the Internet into a hostile ecosystem for innovation, as they limit the deviation from deployed protocols. It is therefore essential, when designing a new protocol, to first understand its interaction with the elements of the path. The emerging area of crowdsourcing solutions can help to shed light on this issue. Such approach allows us to reach large and different sets of users and also different types of devices and networks to perform Internet measurements. In this talk, we show how to make informed protocol design choices by using a crowdsourcing platform. We consider a specific use case, namely the case of pervasive encryption in the modern Internet. Given the latest public disclosures of the NSA global surveillance operations, the issue of privacy in the Internet became of paramount importance. Internet community efforts are thus underway to increase the adoption of encryption. Using a crowdsourcing approach, we perform large-scale TLS measurements to advance our understanding on whether wide adoption of encryption is possible in today's Internet.
Benchmarking Performance of Virtual Network Functions (VNF) -- Al Morton (AT&T)
This talk will introduce the topic of Laboratory Benchmarking, starting with some background on Physical Device Benchmarks. We quickly indicate how the “game” is changing with virtual networking functions deployed in general-purpose computing systems, resulting in many new degrees of freedom in configuration. Next we cover benchmarking new functions of SDN and NFV Infrastructure, such as SDN controllers and Virtual Switches. We conclude by connecting the topics in this talk to the IETF Benchmarking Methodology Working Group (BMWG).
IPv6 Extension Headers in the Real World -- Fernando Gont (SI6 Networks)
This presentation will cover the methodology employed for measuring the support of IPv6 extension headers in the IPv6 Internet, and the corresponding results, which essentially indicate that there is widespread dropping of IPv6 packets that contain extension headers.
