![]() The IP address serves as a unique identifier that enables data packets to be sent and received over the internet. IP operates at the network layer of the OSI model, and it works by assigning a unique IP address to each device on a network. It is a fundamental protocol of the internet protocol suite and is responsible for addressing, routing, and fragmenting data packets. Internet Protocol ( IP) is a network protocol used to deliver data packets from one device to another over the internet. But have you ever wondered how all of our devices are able to communicate with each other over the Internet? The answer lies in Internet Protocol (IP), the backbone of the Internet. This is for example the case for UFZ which is currently connected to the Backbone via DESY.The Internet has revolutionized the way we communicate, work, and live. In this case, it is also possible to set a routing encapsulation or “ GRE tunnel” from the Helmholtz institute to (e.g.) DESY and within this GRE tunnel configure a BGP peering. Some centres don’t have an existing BGP peering with DFN. This is illustrated in the picture below for Helmholtz centre A.Ĭentres without existing BGP peering with DFN ¶ Especially, if a trust relationship between the HIFIS partners can be established, the firewall/IPS system between LAN and router via the “ DFN Helmholtz VRF” could be omitted to allow faster data transfers, because the traffic has not to be deeply inspected. Technical preparations ¶ Centres with pre-existing BGP peering with DFN ¶Įach centre has to configure its routing to the Backbone, and may decide to use dedicated hardware or not. For more details on the transfer service provided by HIFIS, please visit this page. Like this, the transfers are conducted over a route that provides even higher security in addition to using a standard HTTPS connection. This use case is currently being investigated for sharing data between centres when the data itself should not be transferred through the internet. Use case 2: Data transfers using WebFTS over the backbone. This use case is currently being implemented to connect HZDR equipment at XFEL (via DESY) to the HZDR networks which are not normally accessible outside of HZDR’s local network. This is typically a use case when a scientist is working in a satellite station of his institution in another centre and wants to access his home institution’s servers. Use case 1: Direct connection between private IP addresses of two different Helmholtz centres. Two use cases are being developed in the frame of the Helmholtz Backbone: Availability of resources: potentially reduced latency between centres.Simplified access, for example by-passing firewalls for connections between Helmholtz centres.Protection of existing resources, for example shielding a sensitive resource in a Helmholtz centre from public HTTP requests.The following map shows the DFN glass fiber network and the current centres connected to the Helmholtz Backbone.īackground map of Helmholtz centres taken from. It is a virtual local area network, or VLAN, that is orchestrated by DFN in its so-called “Helmoltz VRF”, specific to HIFIS, with no link to the internet. The backbone is an overlay of the DFN X-WiN, using the existing connections Helmholtz centres have via DFN. ![]() The networks of the individual Helmholtz centers are being interconnected on the basis of a high bandwidth network with mutual trust and increased overall security.
