Nicolas Simar – DANTE - TF-NGN Berlin: Premium IP update and LBE tranparency on GEANT 5 Premium IP for MOICANE

Nicolas Simar – DANTE - TF-NGN Berlin: Premium IP update and LBE tranparency on GEANT 6 Next Supported projects LONG (IST ) –IPv6 project –Seven connection between seven sites in Spain and Portugal, 2Mbps each. –Premium IP will be supported in GÉANT and in FCCN, but not in redIRIS for the time being due to setting up of new network.

Nicolas Simar – DANTE - TF-NGN Berlin: Premium IP update and LBE tranparency on GEANT 7 CoS traceroute Modified version of traceroute developed by SEQUIN to help the discovery of the DSCP changes along the path. It allows to verify if the DSCP values are the expected ones.

Nicolas Simar – DANTE - TF-NGN Berlin: Premium IP update and LBE tranparency on GEANT 8 Future Improvement Having central information repository for the contact information and a topology diagram of the equipment along the path. Creation of a tool for monitoring the OWD, IPDV, OWL and to check the available bandwidth. –Target: network operator (and potentially end-users) –Pre-requisite for an operational Premium service

Nicolas Simar – DANTE - TF-NGN Berlin: Premium IP update and LBE tranparency on GEANT 9 LBE transparency Marking on a Juniper M series –Marking only on output-queue (just before the packet emission) –Four output-queues per port (in general) –For each output-queue, two loss-priorities (doesn’t mean they are defined or different ) –For one pair, one tagging value is applied to all the packets in this output-queue and with this loss-priority (or no re- tagging)

Nicolas Simar – DANTE - TF-NGN Berlin: Premium IP update and LBE tranparency on GEANT 10 Current Queue utilisation Queue 0 (weight 5) - loss-priority lowBest Efforttag DSCP 0 highDWStag DSCP 32 Queue 1 (weight 90) - loss-priority lowPremium IPtag DSCP 46 high/ Queue 2 - Unused (reserved for LBE) Queue 3 (weight 5) - network control lowNetwork control tag DSCP 48 highNetwork control tag DSCP 56

Nicolas Simar – DANTE - TF-NGN Berlin: Premium IP update and LBE tranparency on GEANT 11 LBE tranparency GOAL : LBE transparency –Currently the LBE packets are classified in the LBE queue, and are tagged as Best Effort - DSCP 0 –Should avoid the re-tagging to DSCP 0. Solution: remove the tagging done for the Best Effort Easy: no –Because the marking to BE on GEANT is used to change the service to BE for the packets using the Premium IP tagging and the DWS one without being allowed.

Nicolas Simar – DANTE - TF-NGN Berlin: Premium IP update and LBE tranparency on GEANT 12 Solutions These packets have to be classified in another unused –unused queue: and allocate to the queue a weight of 1. – (not good bcs Premium protection) –move all the network control traffic and into => available for tagging to BE Network control classification in under investigation (but not likely).

Nicolas Simar – DANTE - TF-NGN Berlin: Premium IP update and LBE tranparency on GEANT 14 Implications Once LBE service deployed (-> classified in queue 2) –On the first GEANT router, the errant PIP and DWS treated as LBE (queue weight) for tagging purpose. –Then, on the next routers as BE (because tagged as BE on the first one). Acceptable solution? ECN bits kept unchanged.
