FS#36482 — Réseau XDSL Lille

Amélioration

CLOSED
100%
Nous allons basculer les boucles optiques de Lille sur les équipements KOSC dans les prochains jours.

Le réseau optique de Lille se compose de 5 boucles.

Nous allons dans un premier temps basculer un côté d'une boucle qui concerne le NRA LQN59. Ceci aura lieu dans la nuit du 21 au 22 Jan.

Puis dans la nuit du 22 au 23 nous basculerons un côté de chaque boucle sur les équipements KOSC.

Dans une dernière nuit du 23 au 24 Jan nous basculerons les 2eme côté des boucles.

Aux terme de ces interventions, l'ensemble des boucles optiques de Lille seront alors géré par KOSC.

L’impact est une coupure de 15 minutes par NRA.

Moving the rest of the NRAs secondary side to KOSC similar to what we have done yesterday to lqn59.


Comment by OVH - Wednesday, 23 January 2019, 00:42AM

Secondary sides of the Lille NRAs successfully migrated to KOSC, tomorrow night if all ok during the day we will migrate Primary sides to KOSC.

We have noticed some issue on WAS59. You might experience poor connection (packet loss, higher ping, ...)

We are investigating.


Comment by OVH - Wednesday, 23 January 2019, 11:40AM

It seems that it also impact other NRA from the lopp. Still working on it.

So far : ron59 tou59 stm59 san59 was59 ron59 lqn59 can59 hau59 lzi59 asc59 tri59 pil59 boi59 fac59 sec59 lib59.

Our provider is looking for root cause.


Comment by OVH - Wednesday, 23 January 2019, 12:24PM

We swapped to old configuration (using our equipment directly).

fixing the vlan on the rest of NRAs...


Comment by OVH - Thursday, 24 January 2019, 01:13AM

We took 3 measurements to fix packet loss problem:

1- fixing vlan issue on each NRA, to have unique id.
2- replacing optical module on the uplink between ovh and kosc.
3- add a backup link that bypass nexus switch directly to our LAC.

If all good by tomorrow's high traffic, we will do the total migration tomorrow's night.


Comment by OVH - Thursday, 24 January 2019, 15:02PM

We noticed some latency issues/ packet loss for can59 clients, we are moving can59 vlan to backup link.


Comment by OVH - Thursday, 24 January 2019, 23:37PM

Finalizing and migrating all NRA to KOSC.


Comment by OVH - Friday, 25 January 2019, 01:39AM

Migration was successful.
