  This paper deals with the concept of a 'Physical Internet', the idea of
building large logistics systems like the very successful Digital Internet
network. The idea is to handle mobile resources, such as containers, just like
Internet data packets. Thus, it is possible to use the principles of
encapsulation and routing to optimize the freight. The problem is that mobile
resources, such as containers, are not quite similar to data packets, because
they are real and not dematerialized. Thus the handling and the storing of
mobile resources, such as containers, will create imbalances in the logistics
network, leading to starvation or overstocking of logistic network nodes. We
propose in this paper a study addressing this problem leading to some
solutions.
