-The B.A.T.M.A.N. protocol originally only used a single message type (called OGM) to determine the link qualities to the direct neighbors and spreading these link quality information through the whole mesh. This procedure is summarized on the [[BATMANConcept|BATMAN concept page]] and explained in details in "the RFC draft":http://tools.ietf.org/html/draft-wunderlich-openmesh-manet-routing-00 published in 2008. +The B.A.T.M.A.N. protocol originally only used a single message type (called OGM) to determine the link qualities to the direct neighbors and spreading these link quality information through the whole mesh.

This approach was chosen for its simplicity during the protocol design phase and the implementation. However, it also bears some drawbacks: * Wireless interfaces usually come with some packet loss, therefore a higher broadcast rate is desirable to allow a fast reaction on flaky connections. Other interfaces of the same host might be connected to Ethernet LANs / VPNs / etc which rarely exhibit packet loss would benefit from a lower broadcast rate to reduce overhead.
