Description

Babel (also known as BABEL, the Babel Routing Protocol, or BGP-free core) is a loop-free distance-vector routing protocol that is designed to operate without the use of a centralized routing protocol such as the Border Gateway Protocol (BGP). It is an open source routing protocol designed to provide a secure and reliable routing infrastructure for networks of any size and complexity. Babel uses the Diffie-Hellman key exchange algorithm to authenticate messages between routers. It also uses a distributed version of the Flooding Time Synchronization Protocol (FTSP) to ensure that all routers in the network have a synchronized view of the topology. Babel also supports multiple routing table instances, allowing routers to be preconfigured with different routing policies. Babel is designed to be a robust and reliable routing protocol, which is why it is being increasingly adopted by Internet Service Providers (ISPs) to provide a secure and reliable core routing infrastructure. It is also being used to provide an alternative to BGP for small networks such as home networks, allowing for simpler and more secure routing.
