I2P 2.3.0-14-rc Release Candidate Needs Testers
This updated dev build features the changes which were present in
the earlier 2.3.0-12 dev build, plus it updates and implements
handling for "Congestion Capabilities" a new feature which helps
us respond to attackers who attempt to congest the network by consuming
excessive resources.
Help us test this new feature for hardening the network against attack
If you want to help, you can get a dev build at our official Github:
What are Congestion Capabilities?
When you are using I2P to make connections, you can be one of two basic
things, a "Router" or a "Client." Routers make connections to eachother
and they form the I2P Network itself, and Clients are used to build applications
inside the I2P network like HTTP Servers, for instance by forming Tunnels
between routers. In order to build these connections, a Router broadcasts it's
"RouterInfo" to the Network Database, which is where Capabilities come in.
A RouterInfo contains a set of "Capabilities" which indicate what the Router
it represents is capable of. If it is capable of connecting directly or whether
it requires a relay/introducer, on which addresses, whether NTCP2 or SSU2, and
bandwidth tier are all expressed inside the RouterInfo. With this change, when a
router is nearing the limit of what it can handle, it will publish an additional
Capability in it's RouterInfo which will indicate the level of congestion it is
experiencing.
When other routers see that this router is in distress, they can then "back off"
and request fewer or none of their client tunnels be built through the affected
router, giving it time to recover and reducing the chances that it's resources will
be exhausted.
