### The Basics

@I2P comes with two encrypted transport layer technologies that allow @Kovri to securely use [TCP/IP](https://en.wikipedia.org/wiki/Tcp/ip) connections. These technologies (@SSU and @NTCP) are called *@transports*.

### In-depth information

@SSU is encrypted [UDP](https://en.wikipedia.org/wiki/User_Datagram_Protocol) and @NTCP is encrypted [TCP](https://en.wikipedia.org/wiki/Transmission_Control_Protocol). They provide @encryption at the [transport layer](https://en.wikipedia.org/wiki/Transport_layer) so higher level @messages can be sent through @tunnels across the @I2P network.

### Notes

- Read about @I2P's transports on the [Transport](https://geti2p.net/en/docs/transport) page
- Read about the transports layer within the [OSI model](https://en.wikipedia.org/wiki/OSI_model)
