LHCONE DTNs preGDB meeting Gerben van Malenstein CERN
LHCONE & DTNs pre-GDB meeting Gerben van Malenstein CERN • January 10, 2017
Networking Services for Applications • Research & Education Networking • Delivering high-bandwidth connectivity • Networks and exchanges • Prototyping, developing, testing and delivering new services • Collaborating e. g. in LHCOPN, LHCONE, … • Network Services are successful when invisible • Are they underappreciated, not valued, or maybe even completely unknown to application communities (being commodity)? • Basic knowledge of networking for application communities • Underlying processes • Infrastructure/topologies • Technologies • Interaction application and network communities needed

Exchanges & Data Transfer Nodes Concept of a World-wide DTN Architecture: Cees de Laat, Leon Gommans and Gerben van Malenstein – November 2016
Exchanges & Data Transfer Nodes
Exchanges & Data Transfer Nodes • Concept: bringing high-speed storage close to Exchanges • Reference Implementation done by ESnet • Hardware measurements done by Caltech • Understanding/researching a globally common Reference Implementation • Hardware, software, local storage and network protocols, WAN network protocols and paradigm • Persistent infrastructure • Need to establish a paradigm network: • E. g. at CERN, DE-KIT, Nether. Light, Star. Light, Caltech, Asia, Latin America • Building infrastructure needs use cases from scientists • First implementation in 2017 • Needs statements from the experiments on the longer term
