4 GÉANT Testbed Service The GÉANT Testbed Service (GTS) delivers integrated virtual environments as testbeds for the network research community The network testbed resources are dynamically allocated from a real e- infrastructure distributed throughout the GÉ ANT core service area allowing researchers to define, build, test and re build highly scalable, high capacity virtual networks quickly, easily and cost-effectively Jacopo De Benedetto, Mayutan Arumaithurai 6

8 GÉANT Testbed Service For a fast and stable connection, External Domain Ports require a VPN interconnection to one of the GTS facilities (paid service ). NDN Testbed GTS Infrastructure Göttingen Node DFN VPN GTS POD Hamburg Jacopo De Benedetto, Mayutan Arumaithurai 10

9 GÉANT Testbed Service For a fast and stable connection, External Domain Ports requires a VPN interconnection to one of the GTS facilities (paid service). Workaround: use the Internet Access Gateway (IAGW) From GTS v2.0 Architecture Guide: The IAGW is a best-effort service and is implemented using a virtual routing forwarding table (VRF) across the GÉANT IP core. This is essentially a VLAN that appears in each Pod and is bridged to appropriate VMs during activation. The interfaces of the individual devices attached to the subnet typically are limited to 1 Gbps or less. Further, as in conventional IP net works, the interface linking the IAGW subnet to the outside world is shared by all projects i.e. all IAGWs for all the projects managed by a GTS domain will typically share the same total capacity to the Internet (this is not an architectural requirement, but is typical, and currently all IAGWs share a single 1Gbps port).
