Note

This page provides an overview of Grid'5000 network infrastructure. Other useful pages:

Grid'5000 Network Infrastructure

Backbone Network

Grid'5000 backbone network infrastructure is provided by RENATER. RENATER is the French National Telecommunication Network for Technology, Education and Research. More information can be found on renater.fr. RENATER offers about 30 POPs (Points Of Presence) in France, at least one POP for each region, which metropolitan and regional networks are connected on. More than 600 sites (Universities, Research Centers, ..) are interconnected through RENATER.

Renater's WDM infrastructure
10Gbps lambda activated for Grid'5000 in Renater's Dark Fiber infrastructure
Grid5000 IP Network


The actual phase of the network is RENATER-5, the deployment has been completed by January 2009. The "standard" architecture is based on 10Gbit/s dark fibers and provides IP transit connectivity, interconnection with GEANT-2 (http://www.geant2.net/), overseas territories and the SFINX (Global Internet exchange).


All Grid'5000 sites (with the exception of Reims and Nantes) are connected to dedicated 10Gbit/s lambdas on a DWDM infrastructure (see Wikipedia: Wavelength-division Multiplexing for more info).

Reims and Nantes are connected using an L2 VPN.


Grid'5000 sites networks

Grid'5000 sites provide access to a variety of network technologies (both Ethernet and high-performance networks such as InfiniBand). More information is available on the following pages:

The list of high performance networks is available on this page.

Address space for virtual machines

Grid'5000 has two different mechanisms to provide IP addresses to virtual machines: subnet reservation and KaVLAN.

  • Subnet reservation provides a mean to allocate IP addresses in the production (= default) network. This provides a way to avoid conflicts between users, but does not provide isolation: all machines are still in the same L2 network. Subnet reservation is documented in the Virtual_machines_on_the_production_environment tutorial, and on the Subnet_reservation page.
  • KaVLAN provides network isolation through dynamic switches and routers reconfiguration, for the duration of an experiment. Inside a KaVLAN network, users are free to allocate IP addresses as needed. However, some IP ranges are routed to/from the KaVLAN network. KaVLAN is documented in the Deploying_OpenStack_using_KaVLAN tutorial (which provides an introduction to KaVLAN), in the Network_isolation_on_Grid'5000 tutorial (which is a more advanced KaVLAN tutorial), and on the KaVLAN page.

IP subnet assignments for the sites within a global VLANs

A global VLAN is a /18 subnet (16382 IP addresses). It is split so that every site gets one /23 (510 ip) in the global VLAN address space.

Example for the global VLAN of Lille, KAVLAN-12, whose address space is 10.11.192.0/18:

  • Bordeaux: 10.11.192.1 → 10.11.193.254
  • Grenoble: 10.11.194.1 → 10.11.195.254
  • Lille: 10.11.196.1 → 10.11.197.254
  • Lyon: 10.11.198.1 → 10.11.199.254
  • Nancy: 10.11.200.1 → 10.11.201.254
