Section 6 says:
afsdb1, afsdb2, and afsdb3 all provide VLDB service via UDP. The first two have the same priority but have weights indicating that afsdb1 should get about twice as many clients as afsdb2.
It should say:
afsdb1, afsdb2, and afsdb3 all provide VLDB service via UDP. The first two have the same priority but have weights indicating that afsdb2 should get about twice as many clients as afsdb1.
Notes:
The given DNS zone file shows:
_afs3-vlserver._udp SRV 0 2 7003 afsdb1.example.com.
_afs3-vlserver._udp SRV 0 4 7003 afsdb2.example.com.
This means that afsdb2.example.com. as weight 4 (double of weight for afsdb1.example.com.).
According to RFC 2782:
Weight
A server selection mechanism. The weight field specifies a
relative weight for entries with the same priority. Larger
weights SHOULD be given a proportionately higher probability of
being selected.
