Abstract
An example method for congestion control using congestion prefix information in a Named Data Networking (NDN) environment is provided and includes sensing, at a first node, congestion preventing an interest packet from being forwarded over a link to a second node, generating a prefix marker associated with a class of traffic to which the interest packet belongs, generating a negative acknowledgement (NACK) packet that includes the prefix marker, the NACK packet being indicative of congestion for any interest packet in the class of traffic indicated by the prefix marker over any path that includes the link, and transmitting the NACK packet over the NDN environment towards a sender of the interest packet.
