The diagrams in this section provide a summary of the flow of packets through the cOS Core state-engine. There are three diagrams, each flowing into the next. It is not necessary to understand these diagrams, however, they can be useful as a reference when configuring cOS Core in certain situations.

The packet flow is continued below in Figure 1.2, “Packet Flow Schematic Part II”.

The packet flow is continued below in Figure 1.3, “Packet Flow Schematic Part III”.

Apply Rules

The figure below presents the detailed logic of the Apply Rules function in Figure 1.2, “Packet Flow Schematic Part II” above.

The above sequence is described further in the list The Routing Table Selection Process in Section 4.3, Policy-based Routing.
