    摘要： Mechanisms for path continuity determination in an aggregate flow environment. An ingress node and a downstream node for which a path continuity check is desired are determined. The ingress node devolves, from an aggregate flow entry, one or more microflows that comprise packets which are destined for the downstream node. The downstream node is directed to generate corresponding microflows. Each microflow is associated with a continuity set identifier and has one or more timers, such as an idle timer and/or a hard timeout timer. Upon timeout of one of the timers, the ingress node and the downstream node send a microflow termination message that contains the continuity set identifier to a controller node. The controller node determines a path continuity status between the ingress node and the downstream node based on a receipt of one or more microflow termination messages from the ingress node and the downstream node.
