### The Basics
The term *Garlic Routing* has a diverse history of varying interpretations.
As it currently stands, Monero defines *Garlic Routing* as the method in which @Kovri and @I2P create a @message-based anonymous overlay network of internet peers. The @layered-encryption of Garlic Routing is similar to the @layered-encryption of [Onion Routing](https://en.wikipedia.org/wiki/Onion_routing).
### History
In written form, the term *Garlic Routing* can be seen as early as June of 2000 in Roger Dingledine's [Free Haven Master's thesis](http://www.freehaven.net/papers.html) (Section 8.1.1) as derived from the term Onion Routing.
As recent as October of 2016, [#tor-dev](https://oftc.net/WebChat/) has offered insight into the creation of the term *Garlic Routing*:
[Nick Mathewson](https://en.wikipedia.org/wiki/The_Tor_Project,_Inc):
>[I think that there was some attempt to come up with a plant whose structure resembled the 'leaky-pipe' topology of tor, but I don't believe we ever settled on one.]
[Roger Dingledine](https://en.wikipedia.org/wiki/Roger_Dingledine):
>during the free haven brainstorming, there was a moment where we described a routing mechanism, and somebody said "garlic routing!", and everybody laughed.
so we for sure thought we had invented the name, at the time.
Note: permission to use the aforementioned quotes were granted by Nick Mathewson and Roger Dingledine
### In-depth Information
In technical terms, for @Kovri and @I2P, *Garlic Routing* translates to any/all of the following:
- Layered Encryption (like Onion Routing)
- Bundling multiple @messages together (garlic cloves)
- ElGamal/AES Encryption
Note: though [Tor](https://torproject.org/) uses layered @encryption, Tor does not use ElGamal and is not message-based.
### Notes
- In terms of Onion/Garlic Routing, another way to envision layered @encryption is by replacing the onion/garlic with a [Matryoshka doll](https://en.wikipedia.org/wiki/Matryoshka_doll)
