That’s correct and a major feature of the architecture. The way to get 
path diversity and adaptive congestion control is to control the 
propagation of interests in order to control resource allocation for the 
reverse path the data messages traverse. For an example of a recent 
multi-path, multi-destination ICN Congestion control algorithm, check 


Recovery from link failure is accomplished by retransmission of 
Interests, either in-network or by the consumer. ICN pays a lower cost 
for retransmission than end-to-end IP designs, because it supports 
short-term caching of data on the part of the path shared by the 
operating and failed links/nodes.
