WLCG relies on the network as a critical part of its infrastructure and therefore needs to guarantee effective network usage and prompt detection and
resolution of any network issues, including connection failures, congestion and traffic routing. The OSG Networking Area is a partner of the WLCG effort
and is focused on being the primary source of networking information for its partners and...
For several years the HEPiX IPv6 Working Group has been testing WLCG services to ensure their IPv6 compliance. The transition of WLCG central and storage services to dual-stack IPv4/IPv6 is progressing well, thus enabling the use of IPv6-only CPU resources as agreed by the WLCG Management Board and presented by us at previous HEPiX meetings.
By April 2018, all WLCG Tier 1 data centres have...
Recently, we've deployed IPv6 for the CMS dCache instance at KIT. We've run into a number of interesting problems with the IPv6 setup we had originally chosen. The presentation will detail the lessons we've learned and the resulting redesign of our IPv6 deployment strategy.
This presentation provides an update on the global security landscape since the last HEPiX meeting. It describes the main vectors of risks to and compromises in the academic community including lessons learnt, presents interesting recent attacks while providing recommendations on how to best protect ourselves. It also covers security risks management in general, as well as the security aspects...
There are many ongoing activities related to the development and deployment of Federated Identities and AAI (Authentication and Authorisation Infrastructures) in research communities and cyber Infrastructures including WLCG and others. This talk will give a high-level overview of the status of at least some of the current activities in FIM4R, AARC, WLCG and elsewhere.
High Energy Physics (HEP) experiments have greatly benefited from a strong relationship with Research and Education (R&E) network providers and thanks to the projects such as LHCOPN/LHCONE and REN contributions, have enjoyed significant capacities and high performance networks for some time. RENs have been able to continually expand their capacities to over-provision the networks relative to...
The Belle II detector is already taking data by cosmic ray test and is about to record data by beam. The importance of the network connectivity becomes higher than all other experiments in KEK. It is not only for the data transfer but also for researchers who are watching the condition of detectors from off sites.
We will report the present status of the campus network and the upgrade plan in...
Chinese Academy of Sciences has 104 research institutes, 12 branch academies, three universities and 11 supporting organizations in 23 provincial-level areas throughout the country. These institutions are home to more than 100 national key labs and engineering centers as well as nearly 200 CAS key labs and engineering centers. Altogether, CAS comprises 1,000 sites and stations across the...
Present the Network status at IHEP and LHCONE progress in China
Scientific activities generate huge data and need to transfer them to some places to research. Traditional networking infrastructure has a defined architecture and can not satisfy such real-time and high-quality transferring requirements.
China Science and Technology Network(CSTNet) was constructed in order to meet the needs of the research institutes under the Chinese Academy of Sciences and...
