Proximity enforcement in heterogeneous network environments

A method comprising:

• determining a first round trip time associated with a first segment of a network established between a content source and a sink, wherein the first segment of the network is determined to meet a predefined proximity requirement based on a distance associated with the first segment, wherein the predefined proximity requirement is based on one or more content propagation limitations;
• determining a total round trip time of the network;
• calculating a second round trip time associated with at least a second segment of the network, wherein the calculation is made based on the total round trip time and the first round trip time;
