Detailed Description

represents the Routing Information Base

The Routing Information Base contains a collection of Routes, each represents a piece of static or dynamic routing information registered by applications, operators, or NFD itself. Routes associated with the same namespace are collected into a RIB entry.

std::list< shared_ptr< RibEntry > > nfd::rib::Rib::findDescendantsForNonInsertedName ( const Name & prefix ) const

finds namespaces under the passed prefix

Note: Unlike findDescendants, needs to find where prefix would fit in tree before collecting list of descendant prefixes

Returns: { a list of entries which would be under the passed prefix if the prefix existed in the RIB }

void nfd::rib::Rib::beginApplyUpdate	(	const RibUpdate &	update,

passes the provided RibUpdateBatch to FibUpdater to calculate and send FibUpdates.

If the FIB is updated successfully, onFibUpdateSuccess() will be called, and the RIB will be updated

If the FIB update fails, onFibUpdateFailure() will be called, and the RIB will not be updated.
