The government wants this ability to ensure they can protect their Internet assets from foreign aggression and be able to route all traffic internally.
The bill would require telecoms to be able to redirect all traffic through routing points controlled by the Russian state, giving it a brake on the flow of information to networks overseas.
Roskomnazor will inspect the traffic to block prohibited content and make sure traffic between Russian users stays inside the country, and is not re-routed uselessly through servers overseas, where it could be intercepted.
A date for the test has not been set, but is supposed to happen before April 1, according to a law introduced a year ago.
By carrying out this test, Russian Federation is believed to be one step closer to a situation in which all domestic internet service providers will have to direct data through state-controlled routers.
A group of major private and state telecoms led by Natalya Kaspersky, co-founder of the Kaspersky Lab antivirus maker which was banned by the U.S. government, have chose to conduct the test to disconnect "Runet" from the rest of the internet sometime before April 1.
Russia did create a local DNS backup, so theoretically, Russians should still be able to access sites hosted within Runet (the Russian Internet).
According to ZDNet, ISPs across the country are concerned that the new law's implementation could cause a "major disruption".
The move comes after a law was passed in the Kremlin previous year that ordered changes to be made so that Russian Federation could operate independently on the net, should the need arise.
The proposed law, fully endorsed by President Putin, is expected to pass.
The Russian government has agreed to foot the bill and to cover the costs of ISPs modifying their infrastructure and installing new servers for redirecting traffic towards Roskomnazor's approved exchange point. This is similar to the Great Firewall of China, but with the ability to maintain independence with an isolated intranet if needed.
