The Babel routing protocol is a distance-vector routing protocol for Internet Protocol packet-switched networks that is designed to be robust and efficient on both wireless mesh networks and wired networks.

Babel is based on the ideas in Destination-Sequenced Distance Vector routing (DSDV), Ad hoc On-Demand Distance Vector Routing (AODV), and Cisco's Enhanced Interior Gateway Routing Protocol (EIGRP), but uses different techniques for loop avoidance. Babel has provisions for using multiple dynamically computed metrics; by default, it uses hop-count on wired networks and a variant of ETX on wireless links, but can be configured to take radio diversity into account [1] or to automatically compute a link's latency and include it in the metric.[2]

Babel operates on IPv4 and IPv6 networks. It has been reported to be a robust protocol and to have fast convergence properties.[3][4]

Three implementations of Babel are freely available: the standalone sample implementation, a version that is integrated into the Quagga routing suite[5][6] and an independent reimplementation in Python.[7] The version integrated into Quagga allows for authentication,[8] while the standalone version has support for Source-Specific routing[9]
