QoS Deployment

The QoS configuration has been completed on most of the GÉANT routers. The following IP QoS services are deployed:

• Best Effort
• Premium IP
• DWS
• Less than Best Effort.

The deployment map below shows what QoS services are available at which routers. The colour of the routers indicates the services available:

• Routers in green: all services co-exist (Best-Effort, Premium IP, DWS and Less than Best Effort).
  
  
• Routers in yellow: Best-Effort, Premium IP and DWS services co-exist. These routers are Juniper M-40 with older FPC re-used from TEN-155. These FPCs do not have "queue priority" mechanisms, which prevents a perfect isolation of the Best Effort from the Less than Best Effort. The Less than Best Effort will be accepted but in case of congestion, the Best Effort performances will deteriorate.

If you wish to use one of these services and find out that they are not provided on a router, please contact us.
