/barrelfish-2018-10-04/doc/006-routing/
H A D	Routing.tex	184 We assign virtual circuit identifiers at random. At each node, we use a hash table to map virtual circuit identifiers to a pointer to the channel state. The use of a hash table allows efficient message forwarding. When a message arrives, it can be determined where to forward this message by means of a simple look-up in the hash table. The complexity of this lookup is linear in the number of virtual circuit identifiers that map to the same hash bucket (the number of buckets in the hash table is a compile time constant).

Some BIOSs report a memory map that is not sorted by 75 map is preprocessed to eliminate conflicts and ensure ascending addresses. 77 As the preprocessed memory map might be larger due to the case where one memory 79 first need to copy the map into a larger buffer. The memory map is then sorted 82 At the end, regions are page-aligned as Barrelfish can only map whole pages. 94 \caption{Memory map transformation}
