In my previous blog post, I described the three phases in the implementation of the optical layer: installation of new equipment, migration to this new equipment and pick-up of the old equipment. We started installing the equipment in late June, with the first migration scheduled to begin in the second half of August. That means it is time for an update.
Training, testing and installing
The focus during the past and coming weeks is on preparation for the migrations. The engineers have been trained, and a range of tests have been performed or are currently being performed. The migration scenario has been tested and honed in the lab. Our first practical test was the 400 Gbit/s link between Breda and Utrecht. We tested the ECI equipment on an optical fibre that was not yet in use to check whether the equipment is properly configured and works as it should. We did not encounter any problems during that test. We are also developing a test protocol, and we will perform this test at all migration sites.
Supplementary tests on the 400 Gbit/s link
We are currently using the 400 Gbit/s link between Breda and Utrecht for supplementary equipment tests in order to determine how the ECI equipment behaves and how it can be used for the benefit of Dutch education and research institutions. These activities further increase our familiarity with the ECI equipment.
Nearly ready for the first migration
We have been busy installing the new equipment since the end of June. The equipment is installed at all major nodes and at the locations within the first branch (Zwolle to Nijmegen via Deventer, Apeldoorn and Arnhem). This migration is scheduled to take place in the second half of August.
We will visit these locations twice more in the near future: once to test the equipment, and once to prepare the network for migration. We will perform the first migration at night. This will enable us to ensure that the impact is limited in the event that something goes wrong.
We have a sound migration scenario that has been thoroughly tested both in the lab and on site. We expect the migrations to go quickly and smoothly.
Once the first branch has been successfully migrated, we will carry out the other migrations during the day. This will allow us to keep inconvenience to the institutions to a minimum and implement the migrations in a shorter period of time. The second branch we will work on is Zwolle to Nijmegen via Enschede.
