A technical diagram illustrating DLEP flow control in a router-modem system, showing packet flow, credit decisions, and transmit queues.

Create a clean, simple technical diagram in infographic style that explains DLEP flow control in a router-modem system. Show a left-to-right packet flow with labeled blocks: On the far left, an application sending a packet labeled "High Priority". Next, a router block that maps the semantic class "High Priority" to an IP DSCP value. Then a traffic classification step inside the router showing "DSCP -> Flow ID (FID)". Then a credit window decision step showing a check: "Credits available?" with two paths: yes -> forward packet no -> wait for more credits On the far right, a modem with internal queues and a radio link. Also show that the modem grants credits back to the router with an arrow labeled "Credit Window Grant". Use a modern flat design, white background, blue and gray colors, minimalistic networking icons, simple arrows, professional engineering style, easy to understand. Mehr sehen
