ABSTRACT:
Methods, apparatuses and systems facilitating the concurrent classification and control of tunneled and non-tunneled data flows in a packet-based computer network environment. As discussed in more detail below, embodiments of the present invention allow for the “intra-tunnel” classification of data flows and, based on the classification, the deterministic and intelligent application of aggregate bandwidth utilization controls on data flows corresponding to a given tunnel. Embodiments of the present invention allow for the allocation of bandwidth on an application-level basis between tunneled and non-tunneled traffic, as well as between applications within a given tunnel. Other embodiments of the present invention can be configured to provide a differentiated security model for non-tunneled and tunneled traffic. In addition, embodiments of the present invention can be further configured to implement a layered security model for tunneled traffic.
