O2’s overall internet traffic, including isolated peaks, is booming as data demand rises. At the beginning of this year, O2 achieved record data transmission and broke through the 1 Tbps mark. It has responded by significantly increasing the transmission capacity to the Czech peering point, NIX.CZ, with new 400GE Ethernet technology. So far, the operator has been connected to NIX.CZ via five 100-gigabit ports on two lines. It has now increased traffic to 800 Gbps, interconnecting via 2 x 400GE for the first line, with the second to follow by the end of this year.

O2’s internet traffic exceeded 1 Tb/s through a leap in the network’s capacity
“O2 regularly increases its lines both in the backbone network and to NIX.CZ and other peering partners. This year, however, we were the first in the Czech Republic to install a new technology enabling us to increase our transmission capacity by leaps and bounds,” explains Martin Lukeš, IP/transmission technology development manager at O2. “This move will allow us to make better use of the output of the data network’s core elements and to simplify the administration. Not only for our network’s external connections, but within the internal network’s backbones.”
One of the main goals of the current technological improvements is to create a buffer for the peak traffic times currently associated with significant use of home connections for telecommuting, online learning and entertainment.
“Watching online broadcasts of sports events in particular has traditionally put a lot of strain on Czech internet lines. In the past, one in seven viewers watched these broadcasts online, and I expect this trend to grow in the future. This will also be influenced by the fact that the people are unable to attend these events in person,” adds Martin Lukeš.
“NIX.CZ has combined its upgrade of backbone switches with the deployment of 400GE technology. We connected with our largest member via these ports. The upshot of this was that we made the first ever use of 400GE technology on different equipment in the Czech Republic,” says Adam Golecký, NIX.CZ’s director. “400GE technology is the next generational leap. We greatly appreciate the fact that O2 has increased its NIX.CZ connection to 800 Gbps on the first of the two lines. The target is to upgrade the second line this year for a total connection capacity of 2 x 800 Gbps,” adds Golecký.
NIX.CZ statistics show that, during the last week, as much as 67 petabytes (PB) of data flowed through the main Czech internet node, equivalent to approximately 30 million transmitted films of around two GB in size.
