Recent years have witnessed growing consolidation of web operations. For example, the majority of web traffic now originates from a few organizations, and even micro-websites often choose to host on large pre-existing cloud infrastructures. In response to this, the “Decentralized Web” attempts to distribute ownership and operation of web services more evenly.
In this talk we'll go through the design and implementation of the largest and most widely used Decentralized Web platform — the InterPlanetary File System (IPFS) — an open-source, content-addressable peer-to-peer network that provides distributed data storage and delivery. IPFS has millions of daily content retrievals and already underpins dozens of third party applications. We'll go through recent findings on the evaluation of the performance of IPFS by introducing a set of measurement methodologies that allow us to uncover the characteristics of peers in the IPFS network. During our evaluation we found presence of IPFS nodes in more than 2700 Autonomous Systems and 152 countries, the majority of which operate outside large central cloud providers like Amazon or Azure. We evaluated the performance of IPFS and show that both publication and retrieval delays are acceptable for a wide range of use cases.
Yiannis Psaras has a long-standing interest in Information- or Content-Centric Networks with several noteworthy contributions in the area. He has extensive background in several of the architectural and protocol design aspects of Information-Centric Networks having run several projects over the last decade. He sees IPFS as an overlay deployment of ICN in the wild with a huge user-base and is therefore excited to contribute his past experience into the protocol design choices of a live network. Yiannis has been active in the ICN research community and the IRTF ICNRG for several years. In the past, he has worked in areas related to congestion control, routing, caching, naming and resource allocation of current and future fixed and mobile Internet architectures. At Protocol Labs he has led several critical protocol design, operation and infrastructure projects and is currently leading efforts on IPFS network measurements and protocol optimization.
