GlobalNet unveils upgraded backbone route

Services provider GlobalNet has unveiled its newly built backbone running Stockholm-Copenhagen-Hamburg-Amsterdam-Frankfurt-Stockholm.

The six-month project saw GlobalNet use Ciena’s WaveLogic 5 Extreme and the resulting new fibre is routed independently, providing a reservable service through the DWDM ring.

The round-trip delay (RTD) of the Amsterdam to Hamburg line is 11.2 ms; Hamburg to Copenhagen is 4.5 ms; Copenhagen to Stockholm is 8.7 ms; while the Stockholm to Frankfurt leg is no more than 20 ms.

According to GlobalNet CCO, Dimitri Burmistrov, over the last three years the firm has witnessed a "steady increase in the capacity of channels consumed by our network members".

The total capacity of Russia-Europe DWDM channels provided by GlobalNet increased by 11.7% from 2019 to 2020, and by 22.9% from 2020 to 2021.

Burmistrov told Capacity: "The significant rise in the traffic of channels occupied by clients allows us to make an optimistic forecast of traffic growth in the new year by 25-27%. Of course, new infrastructure in a historically traffic-rich region will also play a role here."

Referencing GlobalNet's distributed secure Internet Exchange Point, DATAIX, he added: "At the same time, another reason to outlook the preservation of stable dynamics of our network is the annual increase in the DATAIX peak load. So, in the past year, it reached 5Tbps and went up by 20% compared to 2020".

Sharing the full figures Burmistrov reported 2.8 Tbps in 2018; 3.0 Tbps in 2019; 3.8 Tbps in 2020; and 4.8 Tbps in 2021.

This latest network upgrade follows earlier work to boost GlobalNet's fibre network with 800G wavelength capabilities. GlobalNet has also launched 400G Ethernet technology, making it possible to connect to the network in Stockholm, Frankfurt and Amsterdam using one 400G port instead of four 100G ports.

Commenting on the capabilities enabled by Ciena's equipment, Burmistrov said the programmable capacity from 200G to 800G "brings new levels of scale programmability to optical networking".

He added: "Ciena allows to increase the network density and provide reliable, flexible and cost-efficient access to higher-quality bandwidth to interconnect data centres. Now we are able to evolve to simple, ubiquitous 400GbE client connectivity across any path in the network."
