Abstract
A system may include receiving a packet, of a packet stream, including control tags in a header portion of the packet and classifying each of the control tags into a category selected from a set of possible categories. The set of possible categories may include an unambiguous interposable (UI) category that is assigned to a control tag that corresponds to an unambiguous parsing interpretation and that is interposable within a sequence of the control tags, and an ambiguous interposable (AI) category that is assigned to a control tag in which the control tag has an ambiguous parsing interpretation and in which the control tag is interposable within the sequence of the control tags. The method may further include determining parsing operations to perform for the packet based on the classified categories of the control tags and based on the packet stream of the packet.
