Hunt and Kurtz [9] consider a loss network as the number of circuits a
nd the offered traffics become large. They prove a functional law of l
arge numbers for such a network and illustrate their results with some
simple examples. In this paper we apply their results to slightly mor
e complicated examples to illustrate other, and sometimes surprising,
behaviour of the loss networks in heavy traffic. The networks we consi
der operate under somewhat unusual routing rules but this is to enable
us to produce the behaviour in networks with only a few links. In lar
ger, real-world networks it is likely that much more 'natural' and int
uitively appealing routing rules could produce similar undesirable beh
aviour.
